Understanding gear reducer

Gear reducer is generally used for low speed high torque transmission device, the motor reducer ordinary to the same principle will also have a few gears to achieve the desired reduction effect than the size of the gear teeth is gear ratio. With the continuous development reducer industry, more and more companies use the reducer.
Gear reducer 1, R series coaxial Hypoid Gear Reducer with international technical requirements of manufacturing, high technology content 2, space-saving, reliable and durable to withstand high overload capacity, power up to 132KW; 3, low energy consumption, superior performance, speed reducer efficiency up to 95%; 4, small vibration, low noise, high energy; 5, high-quality forged steel, steel cast iron box, the gear surface after high-frequency heat treatment; 6, through precision machining, to ensure parallel shaft and positioning bearing requirements, forming helical gear reducer assembly configuration of the various types of motors, a combination of mechanical and electrical integration, fully guaranteed product quality characteristics.

Gear motors use to pay attention to those matters?

1, when the gear unit, pay special attention to the central axis of the drive, for errors in the application can not exceed the amount of compensation gear couplings used. Reducer in accordance with the requirements of the following, it is possible to obtain a more ambitious and more lasting effect transmission service life.
2, the fixed wuma gearmotor is very important to ensure a smooth and strong, in general, we should gear unit on a horizontal foundation or base, while behind the oil tank should be able to remove, and the cooling air circulate. Fixed gearhead is not good, is not reliable foundation that will be presented form, oscillation appearance, will make bearings and gears have been unnecessary damage.
3, device orientation gear unit to ensure that operations staff can conveniently near to contain the cursor, breather plug and oil drain plugs orientation. After the device reducer complete view should all view orientation in accordance with the order of accuracy of the device, to determine the reliability of each fastener.
4 gearhead output shaft when the device is transmitting member, you must pay attention to soft operation to stop the use of a hammer and other things rough device, it is best to use to install fixtures and internally threaded end of the shaft of an apparatus to bolts screwed into efforts will Drive pressed into gear, this can not maintain internal parts reducer damaged.

Gear Motor Application Industry

Applications helical worm gearmotor very extensive, machinery and equipment belonging to the indispensable power equipment, especially in the packaging machinery, printing machinery, corrugated machinery, box machinery, transport machinery, food machinery, three-dimensional parking equipment, automated warehousing, warehouse , chemicals, textiles, dyeing and finishing equipment on. Micro gear motor also widely believed to electronic locks, optical equipment, precision instruments, financial equipment in the field.

Gear reducer machine and its configuration form

RV Worm Gear Reducer machine and mill column is an important part two. Their position is between the mill stand and the motor. Their role, in general, is to adjust the output torque of the motor, making it suitable for use in the mill.
Gear machines coming from the motor to reverse the torque distribution to the mill stands of work rolls. Gear motor or flywheel torque coming at high speed into a low-speed torque to suit the rolling purposes. In simple terms, gear machine for transmitting torsional torque distribution, and gear for changing the rotational speed of the motor.
In the old mill motor to the transmission mill work rolls can be by means of gears, belts or rope drive. On newer mills, mostly using the gear mechanism (gear unit and reducer). Sometimes a mill columns, sometimes several mill columns become units, common use of a transmission mechanism.

Gear reducer running-in period of use and maintenance

variable gear motor running-in period for a rational use of oil, especially an input power of more than 11KW reducer shall note the load gear oil. Note Always check the lubricating oil, hydraulic oil, coolant, oil level and quality, and pay attention to check the tightness of the machine. Inspection found a lack of excessive oil should analyze the reasons. At the same time, we should strengthen the lubrication points lubrication recommended run-in period, every week for the lubrication point greasing (except for special request).

Gear reducer Reasons for oil leak

Once the Hypoid Reducer oil spills, not only a waste of resources and pollute the environment, can cause serious gear reducer less oil off the oil, the gear meshing surface wear and tear, bite and then welding or peeling occurs, resulting in equipment accident. Here to talk about common and everyone gear reducer is what causes leakage.
1 gear reducer generating a pressure difference inside and outside
Gear reducer operation, the movement, the friction heat and affected by the ambient temperature, the gear reducer temperature, if no holes or holes to plug, then gradually increase the pressure inside the machine, the higher the internal temperature with the outside world The greater the pressure difference, the lubricant under pressure effect, leaking from the crevice.
2 gear reducer unreasonable structure design
(1) hole cover is too thin, easily deformed after tightening the bolts, the bonding surface uneven, the oil spill from the contact gap.
(2) in the manufacturing process of the gear reducer, casting annealing or aging treatment is not carried out, not eliminate stress, the inevitable deformation, resulting in the gap, resulting in leaks.
(3) did not return to the housing sump, lubricating oil accumulated in the shaft seal, cover, joint surface, etc., under the pressure differential, leakage outward from the gap.
(4) The seal structure design is unreasonable. Early use of gear oil groove, the felt ring type seal structure, so that when the assembly is compressed felt deformed, while the combination of surface cracks sealed. If the spigot in contact with the seal is not very satisfactory, since the compensation performance felt very poor, sealed in a short time lapse. Although the oil groove back hole, but easily blocked, back to the oil effect is difficult to play.
3 excessive amount of fuel
Gear reducer during operation, the oil tank is agitated badly, lubricating oil splashing around in the machine, if an excessive amount of fuel, lubricating oil accumulate in large numbers of seals, the joint surface, etc., resulting in leaks.
4 improper maintenance process at the time of equipment maintenance, due to the combination of surface dirt removal is not complete, or the improper selection of sealants, seals direction anti-loaded, no timely replacement of seals, etc. can also cause oil spills. These are universal finishing gear reducer oil spills cause analysis, in addition in addition to the above reasons, the gear reducer oil spill may also seal quality and assembly process, shaft surface roughness higher aspect, and if found during the operation gear machine oil spills, please calm analysis, properly handle!

helical bevel worm gearmotor when installing and lubrication should be how to deal with helical gear reducer having six basic installation form, as novel reduction gear. Using optimization module combination system of advanced design, with small size, light weight, transmission torque, smooth start, the drive level the score fine and other properties, can choose any connection and a variety of mounting positions according to user requirements. Here we will explain in detail
Helical gear reducer when installing and lubrication should be how to deal with?
First, install
1, the gear reducer general inclination to be installed in the horizontal plane must not exceed 10 °.
2, when the input shaft and the output shaft is coupled with the power and ancillary machinery, as with coupling connection is required shafts and strictly in the heart of the phenomenon can not have a different use of V-belts and chains should not be too tight or too loose.
3, installed base should be solid and reliable, without vibration, loosening fixing screws should be strictly in accordance with the relevant standards and regulations to use.
4, the mounting screws should be tightened from time to time to check whether, stable fixation, the gasket try to use spring washer.
Second, lubricating
1, gear reducer commonly used sump lubrication, note must be added before use good extreme pressure gear oil N220 or N320 to a predetermined position (the lowest portion of the tooth 20-30mm), and regularly serviced.
2, the first 50 hours, should be immediately replaced with new oil and clean the oil inside the body, after completely replaced once every three months.
3, seal leak your own replaced soon.

Identification of the difference between the quality of the materials used gear reducer

Development of PC gear reducer very quickly, less than a half-century Chinese team slowly into the lead in the design and use of materials after decades of research, and now there are different products, materials are provided, in a variety of different models also vary in performance. Gear as the most important components, materials used is certainly the best, forged by the high precision and high hardness of the steel from the gear, used in a variety of gear reducer, if the spiral bevel gear reducer needed after carburizing Surface hardness processes will enhance the process, so that the gear can be unharmed in a variety of work environments. On gear life and jerry effect the product will shine into a huge influence, a serious cause reducer not work.
Box, this is a fixed internal parts of the carrier, but also provide an important part of the seal produced for internal gears, worm and other parts. Often used in the aluminum and cast iron reducer of these two materials forging box, aluminum housing benefits that better heat dissipation, light weight, mainly used in small or micro gear machine. The cast iron type box, its thermal performance is slightly inferior to aluminum, but the power has been made of cast iron products in the cabinet, it can be a good enough weight reducer suppress vibration generated during operation, hardened Processing of cast iron box on the corrosion wear resistance is much higher than the aluminum housing. Reducer main material lies on the gear and housing, of course, the worm also included among the gear. Identification of quality on these two aspects is a good way, in the holds many lessons technologies are mature, is expected to be used to identify the best way to a gear reducer merits.

Factors affecting the gear reducer carrying capacity analysis:

1, the prime mover and work machine load due to the uneven nature of the vertical gear reducer will bring additional external loads. 2, precision gear manufacturing error and speed of operation. Gear machining, assembly process will be errors exist, resulting in relative motion gears in motion the process to bring internal gear additional load. 3, the connection of. When the prime mover is connected with the gear reducer installation of high precision, high additional load that is coaxial, then bring to a smaller gear, otherwise great. Learn how the gear reducer, in order to better use, familiar factors affect the carrying capacity of the deceleration machine in order to better prevent, correct and reasonable use of gear, good lubrication maintenance customers each gear should be noted !

Roller bearing capacity optimization gear teeth of the gear machining process

optimization gearhead heat treatment processes generally mechanical gear is not just the surface hardness of the Cycloidal Speed Reducer Gearbox to the decision, it is also being affected by the surface shear stress to the core of the transition region and the ratio of the size of the shear strength, the ratio should not exceed 0.55. The best way to deal with hardened gear reducer is deep carburizing, it can get sufficient depth of hardened layer, the smaller the transition area as well as a relatively high residual tensile core hardness. Typically the carbon content of the tooth surface is preferably controlled at between 0.8% and 1%, from the tooth surface to the core hardness gradient to ease.
Optimizing machining hobbing process, make rough rolling and finish rolling step processed separately, before fine-dedicated hob hobbing first rough cut with hob, use a dial indicator Cutting depth control, to maintain its precision Cutting depth error to near zero float in, fine tooth hobbing error can not more than 0.03 mm. Tooth machining accuracy is usually to reach more than nine, the tooth surface roughness also consistent with the design requirements. Vibration can be polished or electropolished in grinding teeth after, to improve the surface roughness. Use tooth tip relief, the tooth surface modification and large arc tooth root and other technologies to reduce or eliminate interference engagement and partial load, reduces tooth root stress concentration, increased flexibility gear elasticity. Such as for proper tooth shaving, lapping, grinding teeth and other modifications can increase the contact stress limit of fifteen to twenty-five%; for tooth longitudinally modification, such as repair flanks, can improve gear twice the service life can be reduced to about one fifth bending stress around, it can also reduce noise pollution.

Methods to ensure the normal operation of the gear reducer

1, to ensure the quality of assembly. Some time can be purchased or homemade special tools to remove and install the gear reducer parts, try to avoid tapping with a hammer and other tools; replace the gear, when worm, try to use original parts and be replaced in pairs; assembly output shaft to Note tolerances; to use anti-adhesive or red lead oil to protect the hollow shaft, with the area to prevent rust or dirt wear, difficult disassembly maintenance.
2, the selection of lubricants and additives. combined worm reducer 220 # gear oil is generally used for heavy-duty, start frequently, poor use of the environment reducer, can use some lubricant additives, so that when you stop running gear gear oil is still attached to the gear surface, forming a protective film direct contact between metals at preventing heavy load, low speed, high torque and starts. Additives containing ring modulators and anti-leak agent, the seal ring remains soft and flexible, effective reduce oil leakage.
3, gear reducer installation location options. Lower position permitting, try not to use vertical installation. When vertical installation, the installation a lot more than the amount of the lubricating oil level, could easily lead to fever reducer and oil spills.
4, the establishment of lubrication maintenance of the system. According lubrication "five" Principles of gear for maintenance, so that each person has a responsibility reducer regularly checked and found significant temperature exceeds 40 ℃ or oil temperature exceeds 80 ℃, the quality of oil drops or oil found more copper and generating unusual noise and other phenomena, should immediately stop using and timely maintenance, troubleshooting, replacement of oil. When refueling, pay attention to oil, to ensure correct lubrication of gear.
