Description

Technical Field

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

[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. 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 between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] Reducers are generally used for low-speed and high-torque transmission equipment. The power of electric motors, internal combustion engines or other high-speed running engines is decelerated by meshing the gear with fewer teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio.

[0004] The output shaft is a shaft in the car's gearbox that is 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 output shaft is connected to the transfer case.

[0005] The output shaft needs to be provided with a sealing ring at the connection position with the outside, but the existing output shaft and sealing ring are inconvenient to limit and install. Therefore, we propose a sealing ring limiting clamping device for the output shaft of a wear-resistant reducer. Utility Model Content
