Big power spiral bevel gear reducer

Abstract

The invention relates to a big power spiral bevel gear reducer, which is provided with an engine body and a spiral bevel gear shaft, wherein an output shaft, a first and a second gear shafts are arranged in the engine body, a stop cover is arranged on one end of the output shaft, a through cover is arranged on the other end of the output shaft, end covers are fixedly arranged on the two ends of the first and the second gear shafts through bolts, a key slot is arranged on one end of the spiral bevel gear shaft, the other end of the spiral bevel gear shaft is connected with a spiral bevel gear, the spiral bevel gear is engaged with the first gear shaft, the first gear shaft is engaged with the second gear shaft through a first gear, and the second gear shaft is engaged with the output shaft through a second gear. The big power spiral bevel gear reducer is simpler and more novel in structure, small in whole volume, large in transmission torque, small in noise, large in overload capacity, long in service life and excellent in sealing performance and dustproof performance, can not cause large damage when the power is large, has anti-loose function, and does not affect strength of a shaft.

Description

technical field [0001] The invention relates to a high-power spiral bevel gear reducer. Background technique [0002] The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque, and is widely used in modern machinery.

[0003] The traditional spiral bevel gear hard tooth surface reducer usually includes a box body and an input flange fixedly connected with the box body. An input shaft is arranged at the input flange, and an input gear is arranged at one end of the input shaft corresponding to the box body. However, its transmission The structure of the mechanism is complex, the processing is difficult, and there are disadvantages such as large overall volume, small transmission torque, high noise, small overload capacity, and short service life. It is easy to slip during use and has a great impact on the strength of the shaft. Reduce the safety factor, when the power is large, the axial force is large, resulting in a greatly reduced life of the reducer, and when used in a large dust environment, the reducer has poor sealing performance, and dust is easy to enter it, causing the reducer to fail.
