Interpretation of reducer technical terms

 

When we buy a reducer, we usually encounter some words in the industry. If we don’t understand it, it may be misunderstood, which will affect the selection of the reducer. To understand the parameters of the reducer, first learn these professional terms.

Code: Many engineers will say a few yards and a few yards of the reducer, in fact, this is the power, one yard is equal to 750W, two yards is equal to 1500…and so on.

The reduction ratio, also called the speed ratio, is a very important parameter of the reducer. Its calculation method is: reduction ratio = input speed / output speed. The general standard reducer is 1:1, 1:2, 1:3, 1:4, 1:5, 1:10, 1:15, 1:20, 1:25:1:30, 1:35, 1:40…and so on, some companies will also adjust the reducer according to customer needs.
Number of stages: here refers to the number of gear stages of the reducer, divided into two, four, six, eight… The more poles, the slower the speed, but the higher the torque, the more commonly used is 4 The reducer corresponds to the 4-level motor.
Full load efficiency: Under full load, the transmission efficiency of the reducer is a very important parameter, which should be selected according to your own practical situation.
Working life: The accumulative working time of the reducer under the rated load and the rated input speed. Generally, if the quality of the reducer is not improperly used or used in the wrong environment, high load, the service life is relatively long.
Rated torque: the torque for long-term operation allowed by the rated life. When the output speed is 100 rpm, the life of the reducer is the average life. When this value is exceeded, the average life of the reducer will be reduced. The reducer malfunctions when the output torque exceeds twice.
Noise: The unit is decibel dB (A). This value is measured when the input speed is 3000 rpm, without load, and a distance of 1 meter from the reducer.
Backlash: Fix the input end so that the output end rotates clockwise and counterclockwise. When the output end bears plus or minus 2% of the rated torque, the output end of the reducer will have a slight angular displacement. This angular displacement is the return clearance. Also called “backlash”. The unit is “minute”, which is 1/60 of a degree.
