Dustproof and shockproof gearbox

Abstract

The invention discloses a dustproof and shockproof gearbox, which comprises a box body, an input shaft, an output shaft, a supporting gear and a sliding rod. A partition plate is arranged in the box body; sealing sleeves are arranged at the left side and the right side of the box body; a dustproof ring and an oil seal ring are arranged in each sealing sleeve; the dustproof ring is arranged at theend, away from the box body, of each sealing sleeve, and the oil seal ring is arranged at the end, close to the box body, of the sealing sleeve; the right end of the input shaft runs through the leftside of the box body; the input shaft is arranged on the inner sides of the dustproof ring and the oil seal ring; and the left end of the output shaft runs through the left side of the box body and the partition plate. The dustproof and shockproof gearbox is provided with the sealing sleeves, the dustproof rings and the oil seal rings, wherein the dustproof rings and an oil seal rings are arrangedbetween the input shaft and the sealing sleeves, the dustproof rings are arranged at the ends, away from the box body, of the sealing sleeves and play a role in blocking dusts, and meanwhile, the oilseal rings are arranged at the ends, close to the box body, of the sealing rings and play a role in blocking dusts for the second time; and meanwhile, gearbox oil in the gearbox is prevented from leaking.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a dustproof and shockproof gearbox. Background technique [0002] The gearbox is mainly composed of gears and shafts. Through different gear combinations, variable speed and torque are generated to change the transmission ratio. [0003] The existing gearbox has a single sealing structure, and when the input shaft and output shaft rotate, it is easy to carry dust into the gearbox, contaminate the gearbox oil, and reduce the service life of the equipment. The existing gearbox is not equipped with an anti-vibration device. When vibration occurs, the input shaft and output shaft will follow the vibration, affecting the transmission effect, and the existing gearbox is not equipped with a dust sedimentation device. After a period of use, the friction between the internal gears of the gearbox will generate a lot of dust. The mixing of chips in the transmission oil further accelerate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a dustproof and shockproof gearbox to solve the problem that the existing gearbox proposed in the background art has a single sealing structure, and when the input shaft and output shaft rotate, dust is easily carried into the gearbox and polluted. The gearbox oil reduces the service life of the equipment. The existing gearbox is not equipped with an anti-vibration device. When vibration occurs, the input shaft and output shaft follow the vibration, which affects the transmission effect, and the existing gearbox is not equipped with dust precipitation. After using the device for a period of time, the friction between the internal gears of the gearbox will produce a lot of powder, and the powder mixed in the transmission fluid further accelerates the wear speed of the gears.
