Structure and characteristics of cylindrical gear reducer
Apr 11, 2022

The cylindrical gear reducer is one of the gear reducers. Based on the principle of the gear reducer, it is a mechanical transmission device used to reduce the speed and increase the torque. It uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired speed. The number of revolutions, and obtain a larger torque device. The cylindrical gear reducer is a relatively precise machine, and the purpose of using it is to reduce the speed and increase the torque. Often used in mining, ports, aviation, construction, lifting, machinery and equipment, automobiles and other fields.

The structure of cylindrical gear reducer

 

The cylindrical gear reducer is mainly composed of parallel shaft gears, cylindrical gears, sealing rings, transmission shafts, and boxes; Multi-stage gear reducer, each stage is composed of multiple large and small gears; the large transmission ratio of one-stage cylindrical gear reducer is generally 8-10, and the main limitation is that the outline size is too large. If i>10 is required (i represents the transmission ratio), a two-stage cylindrical gear reducer should be used. The two-stage cylindrical gear reducer is used in the case of i: 8-50 and the sum of the center distances of the high and low speed stages is 250-400mm. The three-stage cylindrical gear reducer is used for the use requirements that require a relatively large transmission. From the above conclusions, it can be seen that the more stages of the cylindrical gear reducer, the greater the reduction ratio, the lower the output speed, the greater the torque, and the greater the noise; otherwise, the smaller it is.

 

Performance characteristics of cylindrical gear reducer

 

Small size, light weight, high precision, large bearing capacity, high efficiency, long service life, high reliability, smooth transmission, low noise; generally oil pool lubrication, natural cooling, when the thermal power can not meet, can use circulating oil lubrication or fan. Cooling coil cooling. The working environment can be -40-50℃, if it is lower than 0℃, it can work normally under special environment. Cylindrical gear reducer, the power and performance of the gear reducer can be designed and customized according to the actual application requirements.
