Embodiment Construction

[0010] The present invention as figure 1 shown.

[0011] The internal sliding lubrication structure of the middle support of the transmission shaft includes the bearing 3 of the middle support seat 1 of the transmission shaft. There is a helical oil groove 5 on the mating surface between the optical axis 4 of the spline shaft 2 and the inner ring of the bearing 3, and the axial distance L1 between the head and the tail of the oil groove 5 is greater than the width L2 of the bearing, and the length from the oil seals 6 at both ends is less than less than 3mm; that is figure 1 The length of L1 is greater than the length of L2.

Abstract

The invention provides a transmission shaft intermediate support internal sliding type lubricating structure, which comprises a transmission shaft intermediate support bearing. The bearing is sleeved on a spline shaft's smooth shaft, the matching surface of the spline shaft's smooth shaft and a bearing inner race is provided with spiral oil grooves, and the straight line distance between the heads and tails of the oil grooves is greater than the width of the bearing, and the distance to oil seals at both ends is not less than 3mm. As the matching surface of the spline shaft's smooth shaft and the bearing inner race is provided with spiral oil grooves, the structure can store lubricating grease and reduce friction coefficient, solve the problems of heat generation by dry friction and abnormal wear, effectively solves the problems of bearing burning-out and abnormal wear caused by sliding friction in a friction process of the intermediate support bearing and the spline smooth shaft, and reduces the incidence of intermediate support damage.

Description

technical field [0001] The invention relates to a transmission shaft in an automobile part, in particular to an internal sliding lubricating structure for the intermediate support of the transmission shaft. Background technique [0002] Inner sliding intermediate support structure, that is, the intermediate support can slide freely along the spline optical axis. The advantage is that when the transmission shaft is subjected to axial impact force, the bearing and the spline optical axis will move axially to relieve the friction between the rubber backing ring and the bearing. Axial forces prevent damage to rubber backing rings and bearings. The disadvantage is that the bearing often slides axially, which will cause dry friction to generate heat, cause the temperature of the bearing to rise, abnormal wear, cause the bearing to burn, and the intermediate support will be damaged prematurely. Contents of the invention [0003] In order to solve the temperature rise and abnorma...
