Description

External Diameter Bearing Jig}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer diameter bearing jig, and more specifically, to an outer diameter bearing jig capable of smooth press-fitting without damaging the bearing when the bearing is press-fitted.

A bearing is a mechanical element that fixes the axis of a rotating machine at a fixed position and rotates the shaft while supporting the weight of the shaft and the load applied to the shaft, and is also referred to as a bearing.

Here, the shaft portion in contact with the bearing is referred to as a journal, and can be divided into two types, sliding bearing and rolling bearing, depending on the contact state.

Rolling bearings come in contact with the ball or roller of the shaft and the bearing, and when the shaft rotates, the ball or the roller rotates together, so the frictional resistance is small.

In the rotating machine shaft, there are cases where the load is perpendicular to the shaft and the shaft is caught in the axial direction, and the bearing is required to perform rotational motion withstanding such a load.

Rolling bearings are divided into ball bearings and roller bearings.

A ball bearing is a steel ball inserted between an inner race and an outer race, or inserted between two discs, and a roller bearing is a bearing in which a plurality of rolls are inserted between an inner race and an outer race.

1, when the bearing 10 is fixed to the machine, the bearing 10 is placed on the upper portion of the bearing fixing groove 1 formed on the machine, and the bearing 10 is pushed or hit, So that the outer diameter of the bearing fixing groove 2 abuts against the inner circumferential surface of the bearing fixing groove 2.

However, the above-described method has a problem in that when the bearing is pressed or hit, the bearing is press-fitted into the bearing fixing groove to cause ball damage or breakage of the bearing.

When the outer diameter of the bearing is simply pressed through a cylinder-shaped jig or when a hitting is applied, the bearing is liable to be damaged due to contact with a bearing steel ball or a roller due to sliding to the side.

In addition, since the indentation of the bearings depends on the skill of the operator, the uniformized work is not performed, the working time is different, and the occurrence of defects frequently occurs.

In addition, malfunction of the mechanical device due to tilting of the bearing may occur.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bearing jig for an outer diameter which can press-fit a bearing without any damage to the bearing.

It is another object of the present invention to provide a bearing jig for an outer diameter which is capable of uniformly performing press-fitting of a bearing, shortening a working time, and causing no failure.

Another object of the present invention is to provide a bearing jig for an outer diameter, in which a bearing fixed to the apparatus is pressed into a correct position to prevent malfunction of the mechanical device.

According to an aspect of the present invention, there is provided a jig for press-fitting a bearing, comprising: a body having a through hole formed therein; a through hole formed in the jig; An inner ring contact portion protruding from the center of both ends in the longitudinal direction of the body so as to be inserted into the inner ring contact portion; an outer ring protruding from an end of the body so as to be spaced apart from the inner ring contact portion by a predetermined distance, And a contact portion.

And bearings of different sizes are inserted into both ends of the body.

And the through hole is inserted with a bolt or the like so that the body can be fixed to the press.

The outer diameter bearing jig according to an embodiment of the present invention has an effect that a bearing can be pressed or a bearing can be easily pressed without damaging the bearing.

In addition, a uniform work of press-fitting of the bearing is achieved, the working time is shortened, and there is no defect occurrence.
