Description
Technical field
This utility model relates to a kind of extracting tool, specifically a kind of small end bearing extracting tool.
Background technology
Small end bearing coordinates with piston pin or crosshead pin, in order to reduce the abrasion of pin.Connecting rod small-end bearing, is often sliding bearing.Without on cross-head type connecting rod, its little-end bearing is frequently with tin bronze, the cylindrical shape axle sleeve of Allen's metal making, or uses inner surface to have the steel axle sleeve of antifriction alloy.Particularity due to its structure, the process of its installation and removal is relatively complicated and complicated, and, it is also easy to small end bearing self is caused certain abrasion in installation repeatedly, unloading process, and then affect its life-span used, in unloading process, result even in it damaged, thus the installation and removal instrument of existing small end bearing needs to be improved.
Utility model content
Utility model purpose: the purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of small end bearing extracting tool.
Technical scheme: in order to realize object above, a kind of small end bearing extracting tool described in the utility model, including: long bolt, left end nut, end cap, auxiliary sleeve, axle, right-hand member nut, described long bolt is through in left end nut, end cap, and described auxiliary sleeve one end is fixed on end cap, and its other end is fixed on the side of small end bearing, described axle is through on long bolt, and, matching with small end bearing in its one end, described right-hand member nut is located at the right-hand member of long bolt.A kind of small end bearing extracting tool described in the utility model; by long bolt, left end nut, end cap, auxiliary sleeve are combined; from one end through small end bearing; and at the other end through axle; finally fasten with right-hand member nut; its simple in construction; install, dismounting the most convenient; it is particularly well-suited to the occasion that service clearance is less; whole connecting rod need not be pulled down, the labor intensity of workman can be alleviated, improve assembly precision; small end bearing body will not be damaged, thus small end bearing body is played a very good protection.
End cap described in the utility model is outer gibbosity, and its center is provided with through hole, and, it matches with auxiliary sleeve, makes it the tightst with what long bolt and auxiliary sleeve coordinated, allows its more fastening connected and stable.
The internal diameter of auxiliary sleeve described in the utility model, more than the external diameter of small end bearing, cooperates between the two, it is possible to ensure that both coordinate each other more preferable.
Axle described in the utility model is ladder shaft-like, and its center is provided with perforation.
The inside of small end bearing is located in its small axle diameter one end of axle described in the utility model, and, its small axle diameter cooperates with the internal diameter of small end bearing, matches with the external diameter of small end bearing in one end of its large-diameter.
Beneficial effect: small end bearing extracting tool described in the utility model, has the advantage that
null1、A kind of small end bearing extracting tool described in the utility model，By by long bolt、Left end nut、End cap、Auxiliary sleeve is combined，From one end through small end bearing，And at the other end through axle，Finally fasten with right-hand member nut，Then acted on respectively on left end nut and right-hand member nut by two spanners，Keep right-hand member nut motionless，Rotate left end nut，Axle is made to be extruded from connecting rod small end hole by small end bearing by the effect of screw thread moment，Small end bearing falls completely within inside auxiliary sleeve，Finally pull down right-hand member nut，By long bolt、Left end nut、End cap、Auxiliary sleeve and axle remove，Its simple in construction，The most convenient for small end bearing dismounting，It is particularly well-suited to the occasion that service clearance is less，Whole connecting rod need not be pulled down，The labor intensity of workman can be alleviated，Improve assembly precision，Small end bearing body will not be damaged，Thus small end bearing body is played a very good protection.
2, the axle described in this utility model is ladder shaft-like, and its center is provided with perforation, its small axle diameter cooperates with the internal diameter of small end bearing, match with the external diameter of small end bearing in one end of its large-diameter, and then improve its stability installed, it is further ensured that follow-up unloading can smoothly complete.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: long bolt-1, nut-2, end cap-3, auxiliary sleeve-4, axle-5, nut-6, small end bearing-7.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model.
Embodiment
A kind of small end bearing extracting tool as shown in Figure 1, including: long bolt 1, left end nut 2, end cap 3, auxiliary sleeve 4, axle 5, right-hand member nut 6.
The relation of above-mentioned each parts is as follows:
Described long bolt 1 is through in left end nut 2, end cap 3, described auxiliary sleeve 4 one end is fixed on end cap 3, its other end is fixed on the side of small end bearing 7, described axle 5 is through on long bolt 1, and, matching with small end bearing 7 in its one end, described right-hand member nut 6 is located at the right-hand member of long bolt 1.
The internal diameter of the auxiliary sleeve 4 described in the present embodiment, more than the external diameter of small end bearing, cooperates between the two.
