Notes for Buying Helical Gear Reducer

Determine the purpose of the reducer purchase

The first step to buy the reducer, we must first determine the purpose of the purchase. For reducer classification, there are cycloid reducer, planetary gear reducer, worm reducer, etc. There is less harmonic gear reducer, the roller cam reducer, toroidal worm reducer, and so on. There are many branches below, and is quite complex to enumerate. And each worm gear speed reducer is not suitable for the same areas. A turbo-worm should be used with ordinary motor; accuracy requirement is high, if equipped with stepper, servo motor, planetary gear reducer should be used; cycloid reducer is rarely see to be used, which is also equipped with high-precision servo motors.

Overall, we must first determine whether to purchase imported reducer, or domestically made reducer, because, as the different manufacturers, it has its own set of name. If not be aware of this, it might bring problem for the work later.



Secondly, we need to have a technical drawing reflecting reducer structure or reducer style. Because when we get the parameters of the reducer, we can analyze whether it is applicable for our production. Here, we need to have a wealth of theoretical knowledge to investigate the reference parameters we understand. This requires a lot of accumulation, but also requires a certain amount of experience, which requires us constantly learning reducer technology.

The following points should be noted when selecting helical gear reducer:

1. Allowable input shaft diameter Reducer input shaft hole and the motor output shaft are generally connected by a collar whose thickness varies. When not jacketed with ring, the reducer input shaft hole is maximum value.

2. Allowable input flange Cannot be greater than or less than the standard size of Pro-stage gear unit, for example, the standard flange for PLE80 reducer is 80mm, the Pro stage PLE60 and PLE120, PLE80 reducer, the maximum allowed flange should not be less than 60mm, but is also not be more than 120mm.

3. Maximum input speed The maximum input speed of the motor is less than the maximum input speed of reducer.

4. Rated output torque The adaptive motor rated output torque multiplies reducer reduction ratio is the reducer output torque, which should be less than or equal to the rated output torque of the reducer.

We need to know certain reducer parameters, but also understand to inject the right amount of lubricant in the reducer before running, choose the viscosity of the lubricant in accordance with the provisions. Working oil temperature must not exceed 80℃. Lfetime lubrication combination reducer is filled with synthetic oil in the factory, in addition, the reducer usually doesn’t have lubricating oil when supplied, but have the oil fill plug and oil drain plug. If the transmission power is more than the heat capacity of the reducer, the external cooling means must be provided.
