Description

Technical Field

[0001] The invention relates to the technical field of reducers, and in particular to a noise-reducing reducer. Background Art

[0002] At present, reducers are widely used in various fields of industry. Reducers are an independent component composed of gear transmission, rod transmission, gears, and worm transmission enclosed in a rigid shell. They are often used as reduction transmission devices between the prime mover and the working machine. Existing reducers will generate loud noises during operation, which will bring inconvenience to the staff. In addition, reducers will generate higher temperatures when used for too long, so it is difficult to dissipate the heat quickly, which shortens the service life of the reducer.

[0003] The prior art discloses a noise-reducing reducer with the authorization announcement number of CN215673515U, comprising a base, a fixed frame is arranged on the base, and a support plate is arranged in the middle and lower part of the fixed frame; when the machine body is running, the spring is used to reduce the vibration of the machine body, thereby reducing the noise generated by the vibration of the machine body when it is working, and the noise generated by the machine body can be effectively absorbed by the cooperation of the sound-absorbing layer, the sound-absorbing board and the sound-absorbing board. At the same time, under the action of the sound-absorbing board and the sound-absorbing board, the noise generated by the machine body is reduced, and the sound-absorbing board can block the transmission of noise, thereby reducing the impact of noise on the outside, and the wind force generated by the two fans is transmitted to the machine body through the opening and the through hole, thereby dissipating the heat of the machine body, so that the heat dissipated will pass through the through hole, the opening and the exhaust port in turn, and finally the heat can be dissipated through the heat dissipation port. However, the reducer and the heat dissipation fan of the utility model are started separately, and the degree of automation is low. If the staff starts the reducer but forgets to start the heat dissipation fan, the heat generated by the reducer during operation will be very large, which will increase energy consumption and shorten the life of the reducer.
