The utility model has the advantages of simple structure, and reasonable design, through the flexible handle and strong the riveting at the spacing bulb in handle both ends of passing the screw rod, can change arm of force length by according to actual need, work efficiency has effectively been improved, smooth bulb can prevent fish tail palm when using simultaneously, a pair of of ski is installed simultaneously and the special drag hook that removes can be controlled, can be under the narrow and small condition in bearing and the betweencenters crack steady bearing of pulling out, the slide is equipped with length simultaneously, the drag hook angle, the different special drag hook of drag hook thickness, can satisfy the different diameter bearings and the clearance condition needs of laminating.

Description

A kind of bearing extractor

Technical field

The utility model belongs to fixture component technical field and in particular to a kind of bearing extractor.

Background technology

Existing bearing and axle are interference fit, and bearing lower surface and axle carry gear and fit clearance requirement high precision, There is high requirement to puller drag hook end surface thickness, drag hook angle and intensity.The bearing finished products puller bought on the market draws Hook gauge cun, angle and eave tile end surface thickness can not meet bearing pull-out demand, so needing to design a kind of bearing extractor, full Sufficient need of work.

Utility model content

The utility model purpose：A kind of bearing extractor is provided, meets the needs of specified conditions lower bearing dismounting.

Technical solutions of the utility model：A kind of bearing extractor, including screw rod, pass through screw rod movable handle and Slide plate and the drag hook that can move left and right on slide plate for a pair that screw rod uses cooperatively, described handle is reserved through on screw rod Hole, the screw thread that described slide plate passes through on screw rod is in mating connection, and described drag hook is sleeved on the corresponding left and right sides of slide plate.

In the utility model：Described handle be respectively arranged at two ends with size identical bulb, by sleeving and riveting in handle two The bulb at end can carry out spacing to handle, prevents handle from skidding off screw rod, wherein said bulb smooth surface impulse- free robustness, smooth Bulb design can effectively prevent user's hand during having an effect from surprisingly scratching.

The beneficial effects of the utility model：The utility model structure is simple, reasonable in design, by the movable hand through screw rod Handle and sleeving and riveting, in the spacing bulb in handle two ends, can change torque arm length according to actual needs, effectively increase operating efficiency, Smooth bulb can prevent from scratching palm when using simultaneously, and it is special that a pair being simultaneously attached on slide plate can move left and right Drag hook, the length of its drag hook, angle and drag hook end surface thickness smoothly can be drawn in the case that bearing and shaft clearance gap are narrow and small Go out bearing, slide plate, equipped with the different special drag hook of length, drag hook angle, drag hook thickness, disclosure satisfy that different-diameter axle simultaneously Hold and fit gap condition needs.

Brief description

Fig. 1 is structural representation of the present utility model；

In figure：1st, screw rod, 2, bulb, 3, handle, 4, slide plate, 5, drag hook.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is further elaborated.

As shown in figure 1, a kind of bearing extractor, the handle 3 including screw rod 1, passing through screw rod 1 preformed hole, sleeving and riveting are in hand Slide plate 4 that the bulb 2 at handle two ends is connected with screw rod 1 screw thread and be sleeved on a pair of drag hook 5 on slide plate 4,

When being embodied as, need the bearing lower end of pull-out by adjusting position on slide plate 4 for the drag hook 5 and putting into drag hook end Face, position on slide plate 4 for the adjustment drag hook 5 is so that drag hook 5 arm of force is vertical and slide plate 4 and drag hook 5 bottom planar horizontal further It is adjacent in the bearing lower surface needing pull-out.Handle 3 is rotated clockwise, under making screw rod 2 gentle behind the position adjusting drag hook 5 Fall, until screw rod 2 top withstands on brearing bore axle.Check again for drag hook 5 position, continuing, after confirmation is errorless, the hand that turns clockwise Handle 3 is until bearing is completed to pull out by drag hook 5.

Above specific embodiment of the present utility model is described, but the utility model is not limited to above retouching State.For a person skilled in the art, any equal modifications and substitutions to the technical program are all in the utility model Scope among.Therefore, the impartial conversion made under without departing from spirit and scope of the present utility model and modification, all should cover In scope of the present utility model.

Claims (2)

1. a kind of bearing extractor it is characterised in that：The movable handle including screw rod, passing through screw rod and screw rod cooperation make Slide plate and the drag hook that can move left and right on slide plate for a pair, described handle passes through reserved hole on screw rod, described The screw thread that slide plate passes through on screw rod is in mating connection, and described drag hook is sleeved on the corresponding left and right sides of slide plate.

2. bearing extractor according to claim 1 it is characterised in that：Described handle be respectively arranged at two ends with size phase Same bulb, can be carried out to handle by the bulb at handle two ends for the sleeving and riveting spacing, prevent handle from skidding off screw rod, wherein said Bulb smooth surface impulse- free robustness, smooth bulb design can effectively prevent user's hand during having an effect from surprisingly drawing Wound.
