Abstract

The utility model relates to the field of tools, in particular to a bearing dismounting tool which comprises a body and a threaded rod and is characterized in that internal threads are formed at one end of the body; external threads matched with the internal threads of the body are formed in a corresponding position at one end of the threaded rod; the head of the threaded rod is tapered; the other end of the threaded rod is designed to be a square head; an inner hole of the body is matched with an excircle of a bearing; and a spacing rib for clamping the bearing is arranged on the other end face of the body; and a bearing removal notch for dismounting is further formed in the body. When the tool is in use, the spacing rib on the body is clamped on the end face of the bearing or in an axial locking groove of the bearing to clamp the bearing; the threaded head of the threaded rod pushes against the end face of a shaft; a spanner pulls and rotates the other end of the threaded rod; the threads are screwed in to allow the body to move outward; the spacing rib drives the bearing to move outward; when the bearing is completely separated from the shaft, the bearing can be removed from the notch of the body; and the tool is simple in structure, convenient to use and low in cost and has good application prospects.

Description

A kind of bearing extractor

Technical field

The utility model relates to field of tool, is specially a kind of bearing extractor.

Background technology

Automobile engine and speed changer axis generally all can adopt bearing with being connected of housing, when bearing removal, general employing knocked dismounting or specific purpose tool dismounting by hand, knocking by hand dismounting is easy to bearing or axle to produce damage, adopt three movable jaws to block bearing face and bearing removal specific purpose tool is in the market general, utilize the axial precession of screw thread, bearing is pulled out, this specific purpose tool complex structure, price is higher, and for a lot of privileged sites, as bearing installation position axial space hour, this specific purpose tool cannot be suitable for.

Summary of the invention

In view of above-mentioned technical problem, the purpose of this utility model provides bearing extractor a kind of simple in structure, easy to use and with low cost.

The utility model is achieved through the following technical solutions:

A kind of bearing extractor, comprise body and screw rod, it is characterized in that: body one end is provided with internal thread, screw rod one end correspondence position is provided with the external screw thread matching with body internal thread, head is arranged to cone, and the screw rod other end is designed to square toes, and the endoporus of body coordinates with bearing top circle, on body other end end face, be provided with the limit rib that fixes bearing, the bearing being also provided with on body for pulling down takes out breach.

Limit rib of the present utility model is used for blocking bearing face or bearing shaft to locking groove.

As preferably, the described cone with external screw thread one end screw head becomes 60 ° of cone angles.

When the utility model uses, limit rib on body be stuck in the end face of bearing or bearing shaft in locking groove in order to block bearing, screw flight head withstands the end face of axle, pulls the other end of rotary screw with spanner, screw thread precession, body is outwards moved, and limit rib band dynamic bearing outwards moves, in the time that bearing departs from axle completely, can from the breach of body, take out, the utility model is simple in structure, easy to use and with low cost, has good application prospect.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the schematic diagram of bearing while taking out from body breach.

Fig. 3 is that the A of body is to view.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model embodiment is further described:

As Figure 1-3, a kind of bearing extractor, comprise body 1 and screw rod 2, it is characterized in that: body 1 one end is provided with internal thread 11, screw rod 2 one end correspondences are provided with the external screw thread 10 matching with internal thread 11, band external screw thread 10 one end screw heads are arranged to cone 8, cone becomes 60 ° of cone angles, screw rod 2 other ends are designed to square toes 5, the endoporus of body 1 coordinates with bearing top circle, is provided with the limit rib 3 that fixes bearing on body 1 other end end face, and limit rib 3 blocks bearing 6 end faces, on body, be also provided with breach 4, for the taking-up of the bearing pulled down.

The course of work of the utility model embodiment is as follows:

When use, first by the breach of body 14 down, be enclosed within on the cylindrical of bearing 6, limit rib 3 blocks the end face of bearing 6, manually screw in screw rod 2, the cone 8 of screw rod 2 external screw thread 10 heads heads in the centre bore 9 on axle 7 end faces, now, pull the square toes 5 of rotary screw 1 other end by the direction of screw thread precession with common manual spanner or pneumatic impact spanner, along with the rotation of screw rod 2, the limit rib 3 of body 1 is with dynamic bearing 6 to move laterally, until bearing 6 departs from completely with axle 7, complete the dismantlement work of bearing 6, by body 1, screw rod 2 and bearing 6 entirety are taken off, screw rod 2 is oppositely screwed out to a part, bearing 6 can take out from breach 4.

Claims
