Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer with good heat dissipation performance. Background Art

[0002] A reducer is a power transmission mechanism enclosed in a rigid shell. The speed and torque are changed through the reducer to adapt to work requirements. The interior of the reducer achieves the effect of speed change through the meshing of gears with a transmission ratio. It is widely used in modern machinery. A large amount of friction heat will be generated during the operation of the reducer, that is, the heat in the body cannot be quickly dissipated in the shell, which will cause a greater risk of thermal damage. The occurrence of this risk will greatly reduce the actual life of the reducer. Therefore, the existing reducers have certain heat dissipation equipment to dissipate the heat when used. However, the existing heat dissipation methods of the reducers are relatively single when used, and the heat dissipation effect is poor. The reducer is still used in a high temperature state, which reduces the service life of the reducer. Therefore, we have introduced a new reducer with good heat dissipation performance.
