Abstract

The utility model relates to a bearing withdrawing device which is composed of an expanding sleeve and a top rod, wherein the expanding sleeve is in a cylinder shape and is provided with more than three through grooves which are uniformly distributed; the head of the expanding sleeve is conical, and a platform, the expanding sleeve and the screws of the top rod are matched. When the bearing withdrawing device is used, the expanding sleeve is arranged in the internal hole of a bearing; a conical head extends out of the internal hole of the bearing and is arranged in the top rod; the head of the top rod is butted with the blind hole surface of a bearing chamber, and after the top rod is rotated, the bearing can be withdrawn. The utility model is suitable for the condition that a bearing of a first shaft of a speed changer of an internal combustion engine is withdrawn from a bearing chamber and similar conditions to withdraw bearings.

Description

A kind of bearing withdrawing device

The utility model relates to a kind of internal-combustion engine vehicle repairing specific tool.Specifically, be the specific purpose tool that the bearing in a kind of explosive motor clutch spindle takes out from bearing chamber.

The automotive internal combustion engines clutch spindle, because of the special assembling relation, its bearing can only be stayed in the bearing chamber when dismounting, and bearing chamber is a blind hole, it is very difficult to want to take out bearing in bearing chamber, the mechanic usually ruins bearing just and has got, and becomes the slight difficult problem in the maintenance work.

The purpose of this utility model is at this specific version, for easily the bearing in the bearing chamber being taken out, and manufactured and designed a kind of bearing withdrawing device of special use.

The utility model is achieved in that

This bearing withdrawing device is made up of ringfeder and push rod, and ringfeder is a tubular, and has groove uniform more than 3, and head is taper, puts into effect, and the conehead maximum gauge is greater than getting brearing bore diameter.There is internal thread at the rear portion, matches with the push rod screw thread, and push rod and ringfeder all are equipped with handle.

During use, ringfeder is put into brearing bore, conehead stretches out outside the brearing bore, after push rod is put into ringfeder, make the push rod head replace bearing chamber blind hole face, rotate the push rod handle, bearing will take out.

Adopt the utility model by the cooperating of ringfeder and push rod, can easily the bearing taking-up be unlikely the damage bearing with uniform active force for bearing inner sleeve.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the bearing withdrawing device working state figure;

As shown in the figure: this bearing withdrawing device is made up of ringfeder 2 and push rod 3, and ringfeder is a tubular, and has groove uniform more than 3, head is taper, puts into effect, and the conehead maximum gauge is greater than bearing 4 diameter of bores, there is internal thread at the rear portion, matches with screw top, and push rod and ringfeder all have handle 1 and 6.During use, ringfeder is put into bearing 4 endoporus, conehead stretches out outside the brearing bore, after push rod is put into ringfeder, make the push rod head replace bearing chamber 5 blind hole faces, rotate push rod handle 1, bearing will take out.

Claims

1, a kind of bearing withdrawing device, formed by ringfeder and push rod, it is characterized in that ringfeder is a tubular, and having groove uniform more than 3, head is taper, puts into effect, the conehead maximum gauge is greater than getting brearing bore diameter, there is internal thread at the rear portion, matches with the push rod screw thread, and push rod and ringfeder all are equipped with handle.
