Flange Linear Motion Bearings

Abstract

The invention provides a flanged linear motion bearing which is easy to manufacture. The flanged linear motion bearing includes a flange annularly provided around an outer cylinder of the linear motion bearing. The linear motion bearing includes an outer cylinder made of a metal material and a cylindrical rolling element fitted inside the outer cylinder. A cage and a plurality of rolling elements held in the cylindrical rolling element cage are characterized in that the flange is formed by providing a mold around the outer cylinder of the linear motion bearing, injecting a fluid resin material into the mold, and then A flange formed by curing injected fluid resin material.

Description

technical field [0001] The present invention relates to a flanged linear motion bearing in which an annular flange is arranged around an outer cylinder of the linear motion bearing. Background technique [0002] Linear motion bearings (linear bearings) support the shaft inserted into the bearing and allow the shaft to slide smoothly in the linear direction (that is, the axial direction) with the driving force applied in the axial direction of the shaft The possible mechanical parts are assembled and used in various mechanical devices. [0003] Linear motion bearings generally consist of an outer cylinder made of a metal material, a cylindrical rolling element cage (spherical bearing cage) fitted inside the outer cylinder, and a plurality of rolling elements held by the cylindrical rolling element cage (spherical bearings). The shaft body is inserted into the inner side of the cylindrical rolling element cage, and is supported by a plurality of rolling elements partially pr...

AI Technical Summary

Problems solved by technology

However, the method of integrally molding the flanged outer cylinder with a metal material is expensive, so it cannot be said to be advantageous as an industrial method.

In particular, there is a problem that, in the case of manufacturing a large number of flanged outer cylinders having the same shape but with different flange shapes or attachment positions, it is necessary to have a mold corresponding to each flange shape or attachment position.

However, in order to securely fix the flange to the outer cylinder, it is necessary to form claws and claw insertion holes on the flange and the outer cylinder in advance, so this cannot be said to be an advantageous method as an industrial method for the flanged outer cylinder.
