2,477 Published by Apr 27,2020

In passenger cars, in order to improve the bending mode of the drive shaft, improve the torque deviation phenomenon, and meet the needs of the vehicle layout, the drive shaft is often divided into three sections. .Bearing bearings play an important role in the normal operation of the three-stage drive shaft.

The installation method of the drive shaft carrier bearing differs depending on the bearing structure, fit, and conditions. Generally, since most of them are shaft rotations, the inner ring needs an interference fit. Cylindrical hole drive shaft carrier bearing, which is usually pressed in with a press, or hot-packed. In the case of tapered hole, install it directly on the taper shaft, or install it with a sleeve.

When installing the drive shaft carrier bearing to the housing, there is generally a large amount of clearance fit, and the outer ring has an interference amount. It is usually pressed in with a press, or there is also a cold shrink fit method for installation after cooling. Dry ice is used as a coolant, and when shrink-fitting is installed, the moisture in the air will condense on the bearing surface. Therefore, appropriate anti-rust measures are required.

The correct installation of the drive shaft carrier bearing affects accuracy, life, and performance. Therefore, the design and assembly department should fully study the bearing installation. Hope to install according to the operation standard. The work standard items are usually as follows:

(1) Cleaning the drive shaft carrier bearing and related parts

(2) Check the dimensions and finishing of the related parts of the drive shaft carrier bearing

(3) Installation

(4) Inspection after installing the drive shaft carrier bearing

(5) Lubricant

Precautions

Generally, the heating of grease-lubricated bearings should not exceed 80 ° C. The heating temperature of oil-lubricated drive shaft carrier bearings should not exceed 120 ° C.

The drive shaft carrier bearing is not allowed to contact the bottom of the oil tank. In addition, the heat sleeve installation can also use an induction heating device to heat the drive shaft carrier bearing to expand it and then install it on the shaft.
