Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer for agricultural machinery. Background Art

[0002] A reducer is a power transmission mechanism, which is mainly used to reduce the speed and increase the output torque. It reduces the speed of the motor to the required speed through the gear speed converter, thereby obtaining a larger torque. Reducers are widely used in various mechanical transmission systems, including lifting, excavation, transportation, construction and other industries.

[0003] Since the reducer needs to frequently replace different rear housing modules to achieve different forms of input such as shaft input, motor input, and IEC adapter flange input; and is compatible with power forms such as internal combustion engines and electric motors, the existing reducer and the replaced rear housing module are usually fixed by bolts, which makes replacement particularly cumbersome. In the Chinese utility model patent announcement number CN 116658573 A, a reducer specifically for agricultural machinery is disclosed, including an engine body and a housing, a connecting flange is installed on the back of the housing, and a first bearing is provided inside the connecting flange and inside the housing. A driving bevel gear, a first driven bevel gear and a second driven bevel gear are provided. When the output coupling rotates, it will drive the first driven bevel gear and the second driven bevel gear to rotate, and then drive the first output shaft and the second output shaft to rotate, so as to transmit the power of the transmission shaft to the first output shaft and the second output shaft through the gear meshing reducer, thereby realizing power diversion, and the power transmission is stable and efficient. At the same time, when the output coupling rotates, it will drive the rotor to rotate. After the rotor rotates, the air circulation speed inside the box body can be accelerated, so that the heat generated during the gear meshing process can enter the heat dissipation hole through the heat conduction hole and dissipate through the heat dissipation hole, thereby improving the heat dissipation effect of the reducer. However, the reducer also has certain defects, that is, the replacement of the rear box module is still fixed by bolts, which is cumbersome to replace. Utility Model Content
