Reducer industry has been rapid development, reducer rapid progress!

Recently from the China General Machinery Industry Association to reduce the speed of the club learned that, with the national infrastructure to further increase efforts in recent years, China's reducer industry has been rapid development. According to the statistics of the slippery crash branch, last year, the industry produced a total of 45 million units reducer, sales income of 2 billion yuan, exports about 100 million US dollars. Experts predict that the "Eleventh Five-Year" period, due to the country's overall economic development, reducer industry, the total economic growth rate will reach double digits.
Reducer in China's development has been nearly 40 years of history, widely used in national economy and national defense industry in various fields. Products from the initial parallel shaft helical gearbox, to the development of five categories of products, namely cycloid reducer, CVT, gear reducer, worm gear reducer, electric drum. According to preliminary statistics, the amount of reducer used in the industry are: electrical machinery, metallurgical machinery, environmental protection machinery, electrical appliances, road machinery, chemical machinery, food machinery, light industry machinery, mining machinery, transportation machinery, construction machinery, building materials Machinery, cement machinery, rubber machinery, water machinery, petroleum machinery, these industries use the number of reducer products accounted for the use of reducer in the industry the total number of 60% to 70%.

Brief Introduction to the Advantages of Spiral Bevel Gear Reducer

The Division of the production of spiral electric motor speed reducer can be based on user requirements for any connection and a variety of installation location options.
The following list of the advantages of Cycloidal speed reducer, for your reference.
1, the internal engagement of the fuselage is good, low vibration frequency, resulting in a small noise, smooth transmission.
2, coincidence degree. Reducing the load of each pair of teeth, the relative increase in the carrying capacity of the gear, long life;
3, because the contact area is large, resulting in large force area, transmission torque, commonly used in heavy machinery;
4, helical gears allow the least number of teeth than the spur gear less teeth, so the helical gear is not prone to root cutting;
5, helical gear mechanism than the straight gear compact, small size, light weight, high transmission accuracy.

First determine what vertical gear reducer, such as cast iron worm gear reducer, aluminum worm gear reducer, gear reducer and so on.
Reducer structure and type of accessories to determine, in understanding the structure of the reducer on the basis of working conditions, the initial requirements to determine the following:
1, reducer transmission series selected, reducer transmission series is based on the working advantages of variable speed drives, by the transmission type, transmission ratio, space position and size requirements.
2, to determine the form of transmission parts, there is no special requirements, the axis as far as possible the use of horizontal layout (such as horizontal reducer). For the two-stage cylindrical gear reducer, the size of the transmission power and the layout requirements to determine the use of expansion or coaxial.
3, the primary type of bearing, the general reducer are used both rolling bearings and sliding bearings, rolling bearing type by the load and speed requirements. Select the bearing should also consider the bearing adjustment, fixed, lubrication and sealing and other issues, and determine the end cover structure.
4, the body structure of the reducer decision, usually in the absence of special requirements, the gear reducer body is used along the gear axis level of the structure, in order to assemble.
5, select the coupling type, high-speed shaft commonly used elastic coupling, low speed shaft commonly used portable rigid coupling

Hypoid Reducer selection is good, it is recommended that the reducer test run without load, it should be the load test run. Load in the test should be at the rated speed, respectively, according to the reducer rated load of 25%, 50%, 75%, 100% in four stages slowly loading. And each stage of the operation time to stabilize the temperature of lubricants prevail, in more than 2 hours. Load test reducer, for commutation or not indicate the direction of rotation of the PC gear reducer, should be positive and negative test. For unidirectional reducer, one-way test is allowed, but the direction of rotation of the test must be consistent with the work.

There are many types of vertical gear reducer, if the type of gear transmission can be divided into: worm reducer, cylindrical gear reducer, bevel gear reducer, worm - industrial gearbox types. If the transmission series can be divided into: two-stage reducer and single-stage reducer and multi-stage reducer. According to the gear arrangement can be divided into points: coaxial, split and expand the three. According to the installation can be divided into: horizontal and vertical. According to the casting type can be divided into cast iron and aluminum alloy two.
