Description

Technical Field

[0001] The utility model relates to the technical field of output shafts of reducers, in particular to a seal ring structure for the output shaft of a wear-resistant reducer. Background Art

[0002] The reducer is a relatively precise machine that matches the speed and transmits torque between the prime mover and the working machine or actuator. The purpose of using it is to reduce the speed and increase the torque. It has many types and models, and different types have different uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the shape of the gear, they can be divided into cylindrical gear reducers, bevel gear reducers and bevel-cylindrical gear reducers; according to the layout of the transmission, they can be divided into expansion reducers, split reducers and coaxial reducers.

[0003] The second shaft, also called the output shaft, is a shaft in the car gearbox, directly connected to the drive shaft (transmission shaft), outputs torque and speed, and then drives the car through the differential. In a four-wheel drive car, the second shaft is connected to the transfer case. The output shaft needs to be sealed during use to isolate the inner and outer cavities of the transmission.

[0004] However, the sealing structure of the output shaft is mostly fixed and requires professional equipment to assemble. It is very inconvenient to use for equipment that requires regular disassembly and maintenance, and is not suitable for multi-scenario use of small-batch equipment. For this reason, we propose a sealing ring structure for the output shaft of a wear-resistant reducer. Utility Model Content
