Abstract

The utility model relates to a detacher making unilateral disassembly on an automobile rolling bearing or rolling bearings on inner bores of deceleration box bodies of other facilities, which is composed of a support frame, a screw rod, a nut screw and a taper sleeve. The utility model causes the work to conveniently remove the bearing in high safety and reliability by utilizing the principle of screw and conical body reinforcement in the physical mechanics. The utility model has the advantages that the service life of the facility is extended, the repair cost is decreased, etc.

Description

A kind of stripping attachment

The present invention relates to the provision for disengagement that a kind of rolling bearing that will be installed in the casing carries out one-sided dismounting.

At present, during the dismounting of rolling bearing on automobile or the miscellaneous equipment deceleration box endoporus, the master worker beats with hand hammer, both required great effort like this, again fragile bearing and mating surface, to making a big impact in the safe operation and service life of equipment.

The objective of the invention is to utilize spiral and bullet reinforcement principle in the physical mechanics, provide a kind of and not only can not damage bearing and mating surface but also labour-saving shaft bearing replacer.

The utility model is finished in the following way: promptly comprise support, screw rod, tapered sleeve, handle nut, clamp nut composition, support is " door " body, and there is a hole at the center, screw rod can therefrom pass, screw rod is provided with silk, and the lower end is provided with a cone, and tapered sleeve is two, it is half lonely shape, tapered sleeve is provided with bayonet socket, it can be fastened on the cone by bayonet socket, and tapered sleeve inclined-plane gradient is the same with cone, the another side of tapered sleeve combines with bearing inner wall, and it is parallel with awl bar center line.On screw rod upper end and support, be equipped with handle nut, be equipped with clamp nut in the cone upper end.

The present invention has simple in structure, and easy operating is laborsaving, does not damage advantages such as work package.

Accompanying drawing is the structural representation of stripping attachment.

The 1st, rolling bearing, the 2nd, casing, the 3rd, tapered sleeve, the 4th, cone, the 5th, clamp nut, the 6th, clamp, the 7th, support, the 8th, pad, the 9th, handle nut, the 10th, screw rod.

Further specify below in conjunction with accompanying drawing, during use, stripping attachment support (7) is put on the working face (2), loosening handle nut (9) is put down screw rod (10), loosening clamp nut (5), cone (3) is enclosed within on the cone (4), be fixed by bayonet socket with clamp (6), then cone (4) and cone (3) are together stretched in the interior cover of rolling bearing (1), built-in length contacts with the inner face of the axial limiting platform of movable tapered sleeve (3) and rolling bearing (1) and is as the criterion, and tightens clamp nut (5), and cone (4) and tapered sleeve (3) are connected as a single entity, pulling handle nut (9) gets final product work.

Claims (1)

1, a kind of stripping attachment, it comprises support (7), screw rod (10), handle nut (9), clamp nut (5), tapered sleeve (3), one hole is arranged at support (7) top, screw rod (10) can pass from the hole, screw rod (10) upper end is provided with silk, the lower end is cone (4), screw rod (10) is provided with handle nut (9) and clamp nut (5), it is characterized in that: tapered sleeve (3) is two, it is half lonely shape, the upper end of tapered sleeve (3) is provided with bayonet socket, and clamp (6) can be installed in tapered sleeve (3) on the cone (4) of awl bar (10), and the gradient of tapered sleeve (3) is the same with the gradient of cone (4).
