Detailed introduction of speed ratio of helical gear reducer

A gear reducer is a relatively precise device designed to reduce speed and increase torque. There are many types of reducers, which can be divided into gear reducers, worm gear reducers, and planetary reducers according to the type of transmission device. According to different transmission stages, it can be divided into single stage and multi-stage reducers; According to the power level, speed reducers can be divided into high-power speed reducers and low-power speed reducers. Widely used in intelligent robots, automation industrialization, intelligent wearable devices, and other fields.

Describe the speed ratio of the gear unit:

A reducer is also known as a reducer or gear box. Inside the gear box, multiple sets of reduction gears are meshed to transmit transmission equipment commonly used for low rotational speed and high torque. The motor, motor, or other high-speed running power is used to achieve the purpose of deceleration by meshing the small number of teeth on the input shaft of the reducer with the large gear on the output shaft. An ordinary reducer also has several pairs of gears with the same principle to achieve ideal deceleration effect, The ratio of the number of teeth of large and small gears is the transmission ratio. The reduction ratio, or the transmission ratio of a reduction device, is a type of transmission ratio that refers to the ratio of the instantaneous input speed to the output speed in the reduction mechanism, represented by the symbol "i". The general method for expressing the reduction ratio is to use 1 as the denominator and use ":" to connect the ratio of input speed to output speed. If the input speed is 1500 r/min and the output speed is 25 r/min, the reduction ratio is: i=60:1.

The reducer is an independent component consisting of a gear drive, worm drive, and gear worm drive enclosed in a rigid housing, commonly used as a reduction transmission device between the prime mover and the working machine.
