Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a heat dissipation protection shell of a reduction motor. Background Art

[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, a gear and a worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. Reducers are generally used for low-speed and high-torque transmission equipment. The power of the electric motor, internal combustion engine or other high-speed operation is reduced by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft to achieve the purpose of reduction. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

[0003] In the prior art, the utility model of Chinese patent application No. 202220219665.1 discloses a high heat dissipation fan reducer, including a heat dissipation base, heat dissipation ports are opened on all sides of the heat dissipation base, a heat dissipation shell is fixedly installed on the top of the heat dissipation base, a reducer body is arranged in the heat dissipation shell, two heat dissipation fans are fixedly installed on both side surfaces of the heat dissipation shell, a heat dissipation cavity is arranged in the gap between the heat dissipation shell and the reducer body, and water tanks are arranged on both sides of the bottom surface of the heat dissipation cavity. The fan reducer can conveniently conduct the heat generated by the reducer when working to the heat dissipation fan through a plurality of heat-conducting columns, and then the heat dissipated into the heat dissipation cavity is discharged out through the heat dissipation fan. At the same time, by arranging heat dissipation oblique fins and support plates under the reducer, the heat accumulated at the bottom of the reducer can be effectively discharged, and further by arranging a condenser and a heat-conducting column and making them cooperate with each other, the heat at one end of the heat-conducting column is effectively absorbed and taken away, thereby improving the service life of the reducer and increasing the working efficiency of the reducer.

[0004] However, in the above technical solution, since the cooling fan is exposed to the outside, when the cooling fan is running, external dust will be brought into the interior of the cooling housing and attached to the reducer. In the long run, a large amount of dust attached to the reducer will affect the normal heat dissipation of the reducer and reduce the speed at which the heat inside the reducer is dissipated to the outside, thereby causing the reducer to overheat and be damaged. For this reason, we propose a heat dissipation protective housing for the reduction motor to solve the above problem. Utility Model Content
