Abstract

The invention discloses a planetary reducer, which comprises a reducer main body, a reducer box for placing the reducer main body, a case cover, an end cover, an input shaft and an output shaft. The reducer main body includes a sun gear, a Mesh and rotate planetary gears and planetary carriers for supporting planetary gears; grooves are provided on the inside of the case cover to place rubber gaskets and input shaft bearings; the first end surface of the sun gear is connected to the input shaft and is integrally processed with the input shaft ;The input shaft is connected to the external drive through the input shaft bearing, the rubber gasket, the input hole of the case cover and the input hole of the end cover; the end cover is used to seal the gap between the input shaft and the case cover; the rear end of the planet carrier is connected with The output shaft, and the output shaft and the rear end of the planet carrier are integrally processed; the output shaft is connected to the external load through the output shaft bearing and the output hole of the reducer box; The planetary gear meshes; the box cover and the reducer box are connected by threads.

Description

technical field [0001] The invention belongs to the design field of planetary reducers, in particular to a planetary reducer which is convenient for assembly, disassembly and fault diagnosis in engineering machinery. Background technique [0002] In the field of mechanical technology, the reducer has a series of advantages such as accurate transmission ratio, large range of available transmission ratio and transmission power, high transmission efficiency, long service life, compact structure and reliable operation. The reducer plays the role of reducing the speed and increasing the torque between the prime mover and the working machine to meet the needs of the work. It is widely used in large and high-power construction machinery. It is an indispensable mechanical transmission device. [0003] However, when the transmitted power is large, it is necessary to increase the size of each part of the reducer to increase the load strength of the reducer. This will inevitably incre...
