Speed control method

The gear speed reducer is a decelerating motor with fixed speed. Once the speed ratio is selected, the motor reducer is selected and the final output speed is fixed. Various speed control methods used in pre-engineering.
1. It is the simplest and most economical method for speed adjustment. There are usually only two speeds, and the speed adjustment ratio is smaller (l: 2, 1, 6) and the limit is three. The speed of regulation is small, although it has the speed.
2. Stepless speed regulation can be divided into mechanical and electrical. The former common method is to insert mechanical stepless speed adjusting device in the connection of motor and gear box. The advantage is that the speed reducers is stable, the structure is not complicated, it is suitable for the bad environment; The disadvantage is that the belt and friction plate of the speed range is a consumable part, which needs to be replaced regularly. The latter is for the asynchronous motor to perform cascade speed regulation, rotor resistance speed regulation or to the dc motor to adjust speed regulation.

How to choose reducer

General vertical gear box selection includes the original conditions, select the type, determine the specifications and other steps.
In contrast, the type of choice is relatively simple, and accurately provide the conditions of the reducer, master reducer design, manufacture and use of the characteristics of the general reducer is the right choice of the key to the key. Specifications are selected to meet the strength, heat balance, shaft extension to bear the radial load and other conditions.
1. According to the mechanical power or torque selection specifications (strength check)
Hypoid Gear Motor and special reducer design selection method is the biggest difference, the former applies to various industries, but the deceleration can only be designed according to a specific working conditions, so the user needs to be based on their own requirements to consider different correction factors , The factory should be the actual selection of the motor power (not the rated power of the reducer) to nameplate; the latter according to the user's specific conditions designed to consider the coefficient, the design has generally been considered, as long as the use of power to meet the use of less than or equal to slow The rated power of the device can be, the method is relatively simple.
Second, the thermal balance check
The permissible thermal power value of the shaft mounted speed reducer is the maximum equilibrium temperature (typically 85), which is permissible under the conditions of a specific working condition (normal ambient temperature 20 ° C, 100% per hour, continuous operation, 100% power utilization) ° C). Conditions are different when the corresponding coefficient (sometimes integrated into a coefficient) to amend.
3. Check the radial load on the shaft extension
General reducer often must be on the input shaft, the output shaft shaft to allow the middle of the maximum allowable radial load to give restrictions should be checked, should be made to the manufacturer when the increase in shaft diameter and increase the bearing requirements.
