Taper bearing press-fitting fixture and bearing press-fitting fixture for vehicle steering column

Abstract

The invention discloses a taper bearing press-fitting fixture. The taper bearing press-fitting fixture comprises a cylindrical fixture body, wherein an axially-penetrating guide hole is formed in thefixture body; a placement groove coaxial with the guide hole and used for placing a taper bearing is formed in one end of the fixture body; the sidewall of the placement groove is a conical surface used for forming transition fit with the outer race of the bearing; and an annular bypass groove used for accommodating a bearing retainer is formed in the bottom of the placement groove. During taper bearing press-fitting, the taper bearing is placed in the placement groove of the fixture body, radial location for the taper bearing is realized, and the deformation of the bearing retainer due to extrusion during taper bearing installation can be avoided; then the fixture body sleeves a steering column through the guide hole, and the guide hole is capable of playing the role of preliminary guide;then the taper bearing is pressed into a specified position on the steering column by virtue of a tool; and the taper bearing press-fitting fixture is simple and convenient, and capable of improvingthe bearing press-fitting quality and the bearing press-fitting efficiency. The invention further discloses a bearing press-fitting fixture comprising the taper bearing press-fitting fixture, for a vehicle steering column.

Description

technical field [0001] The invention relates to the technical field of bearing installation, in particular to a tapered bearing press-fitting tool. In addition, the present invention also relates to a press-fitting tool for a steering column bearing of a vehicle comprising the above-mentioned press-fitting tool for a tapered bearing. Background technique [0002] The steering column is a part that assists turning on the vehicle. During the production and assembly process, the steering column needs to be pressed into a tapered bearing. The tapered bearing is usually composed of a tapered outer race, a bearing cage and an inner ring of the bearing seat. [0003] At present, when the bearing is pressed, the bearing is usually inserted into one end of the steering column first, and then pressed into the designated position on the steering column with a hammer or a press. This pressing method has the disadvantages of inaccurate bearing positioning, low installation efficiency and...

Problems solved by technology

[0003] At present, when the bearing is pressed, the bearing is usually inserted into one end of the steering column first, and then pressed into the designated position on the steering column with a hammer or a press. This pressing method has the disadvantages of inaccurate bearing positioning, low installation efficiency and easy damage. The bearing causes problems such as bearing deformation and affects the quality of subsequent assembly
