Problems solved by technology
However, the piece gear and the output shaft parts used for the assembly of the reduction box are press-fitted after heat treatment. Due to the influence of the machining accuracy of the straight grain part of the output shaft and the deformation of the heat treatment process, the pressure-fitting of the deadly gear and the output shaft is more difficult. After assembly, the output shaft and the plate gear sometimes resonate. If the mutual friction is not enough, it will cause slipping and out of gear. cause negative impact

The invention discloses an improved integrated mechanism of an output shaft and a disk gear of a reduction gearbox. The output shaft is arranged at one end of a reduction gearbox body, and a fixed end cover is arranged at the other end of the reduction gearbox body. The disk gear is connected to the position, located in the reduction gearbox body, of the output shaft, and the disk gear and the output shaft are integrated. An output shaft bearing is arranged on one side of the output shaft, and an output shaft flange plate is arranged on the other side of the output shaft. In addition, the output shaft is tightly installed in the reduction gearbox body through an oil seal. According to the scheme, the output shaft and the disk gear are integrated, torque transmission is better facilitated, slipping and gear disengagement caused by resonance and insufficient mutual friction generated by press fitting of the output shaft and the disk gear are avoided, the assembling difficulty and the machining difficulty are effectively reduced, and the bearing torque and the movement precision are improved; and meanwhile, noise generated by a speed reducer is greatly reduced.
Description
technical field [0001] The invention relates to a machine for press-fitting a piece gear and a straight-grain part of an output shaft, in particular to an improved integrated mechanism of a reduction box output shaft and a piece gear, which belongs to the technical field of reducers. Background technique [0002] The reducer is widely used in modern machinery. It is the transmission part between the prime mover and the working machine, and plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. Generally, the high speed and low torque input by the original moving part are converted into high torque and low speed output to the working machine through the gear set, so it is called a reducer. [0003] From the structural point of view, the reducer is an independent component composed of gear transmission, worm transmission, gear-worm transmission and other methods enclosed in a rigid shell. In the prior art, the...
