Notes for Gear Reducer Selection

A few things should be noted when select models of the reducer: Try to use close to the ideal reduction ratio: reduction ratio = servo motor speed / reducer output shaft speed

The torque calculation: In terms of the life of the worm gear speed reducer, torque calculation is very important and pay attention to the maximum torque value of acceleration speed (TP) , whether it exceeds the maximum load torque of the reducer. Applicable power is usually applicable power of models on the market, the reducer is high applicable, work coefficient can be maintained at more than 1.2, but you can also choose according to your own needs, there are two main points:

A. The selected motor output shaft diameter is not greater than the maximum shaft diameter in the form; B. If work by the torque calculation, the speed can meet the normal operation, but has insufficient phenomenon in full output, we can do the current limit control on the drive by the motor side, or make torque protection in the mechanical axis, which is very necessary

Selection of general reducer

Selection of general reducer includes asking the original condition, choose type, to determine the specifications and other steps. In contrast, type selection is relatively simple, but accurately providing reducer working conditions, to master the design, manufacture and use characteristics of the helical gear reducer are the key to correctly and reasonably choose specifications. Specifications selection should meet the intensity, the heat balance, shaft extension parts bear radial load conditions.



Choose specifications by mechanical power or torque (strength checking)

The biggest difference between universal reducer and special reducer design selection method is that the former is applicable to various industries, but deceleration can only design according to a specific working condition, so at the selection, users need to consider different correction factors in accordance with their respective requirements, the factory should make the nameplate according to the actual optional motor power (not reducer rated power); the latter design according to the special conditions of the user, the coefficients need to be considered generally has been considered at design, only if the power is less than or equal to the rated power of the gear, it is ok, which can be relatively simple.

Currently, the coefficients used by the countries in the world are basically the same. Though many samples do not reflect KS \ KR two coefficients, but because confidant (clear about the requirements), knowing your enemy (clear about the performance characteristics of reducer), we generally leave large wealthy amount at the time of foreign selection, which is equivalent to consider the impact of the KR \ KS.
