Transmission shaft support unit

Abstract

The invention discloses a transmission shaft support unit, belongs to the technical field of bearing production, and mainly solves the problem of damage of the transmission shaft support unit caused by easy release of a support bearing and function loss of a rubber pad in the prior art. The transmission shaft support unit is characterized by comprising a support base, a rubber shock pad, a support bearing and a sealing ring, wherein two snap spring grooves and a large inner snap spring are arranged in an inner hole of the support base; honeycomb blind hole grooves are formed in two peripheral end surfaces of the rubber shock pad; two snap spring grooves, a small inner snap spring and a waveform spring are arranged in an inner hole of a metal ring; the support bearing adopts an inner-outer ring integrated four-point contact ball bearing; an outer lip of the sealing ring is fixed in the inner hole of the metal ring; and the inner diameter of a sealing lip is lightly contacted with and fits the outer diameter of the inner race of the support bearing. The transmission shaft support unit has the characteristics of improving the axial bearing capacity of the bearing, reducing the axial impact load, improving the torque resistance and preventing the release of the support bearing to prolong the service life of the bearing, and is mainly applied to an automotive transmission shaft support unit.

Description

technical field [0001] The invention belongs to the technical field of bearing manufacture, and in particular relates to a long-life transmission shaft support unit, which is a bearing unit product. Background technique [0002] The transmission shaft support unit is an important part of the automobile transmission system. Due to the large vibration and frequent axial impact loads when the automobile is in operation, and the bearings bear a large torque to a certain extent, the working conditions are very harsh, so the support bearings are very easy to loosen. In addition, the rubber pad used in the original support has a large permanent deformation under high temperature and high pressure conditions, and the precision of the rubber pad is reduced, resulting in loss of function, resulting in damage to the drive shaft support unit. Therefore, it is necessary to improve the structure of the existing transmission shaft support unit, reduce the axial impact load, increase the ax...
