Abstract
The utility model provides an automobile half axle bearing remover, belonging to the design and manufacture technical field of the automobile half axle bearing removal tool. The utility model consists of a hydraulic cylinder and a half axle sleeve. A lower plunger piston in the hydraulic cylinder is provided with an addendum cone. The lower part of the hydraulic cylinder is provided with a positioning rod. The internal wall of the half axle sleeve is provided with a thread. The application of the product is that the end of the half axle extends into the half axle sleeve. The addendum cone bears against the central part of the half axle and firmly combines a half axle supporter with a fixed base through a bolt. After that, a plunger piston of the hydraulic cylinder is pressed so as to lead the lower plunger piston to move downwards gradually and lead the addendum cone to bear against the downward movement of the half axle end. As the bearing is beared against by the half axle supporter and keeps still, the half axle gradually moves downwards, thus leading the bearing to separate from an interference fit area and the half axle. The automobile half axle bearing remover has the advantages of simple structure, reasonable design and extremely convenient and fast disassembly of the bearing, and solves various problems of the removal which are caused by the existing autogenous cutting method.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of automobile axle shaft bearing extractor.
Background technology
At present in motor vehicle repair, be a pretty troublesome job for the dismounting of axle bearing.Because the bearing on the semiaxis is that interference fit combines with semiaxis, and is very tight.In the time of need changing as bearing wear, generally all adopt the method for gas cutting, directly bearing is destroyed just and can take off.Change new again.But in gas cutting, because high temperature causes the damage of oil sealing again again to the glue system oil sealing direct baking on bearing next door.So up to the present, the dismounting for axle bearing does not also have any better method.
Summary of the invention
At above-mentioned situation, the utility model provides a kind of axle bearing replacer, and it is convenient and swift to operate, and has solved the problem that existing dismounting form is brought.
Structure of the present utility model is as shown in drawings: be made of axle tube and hydraulic cylinder.Have a hydraulic cylinder on the top of body, a depression bar cover is arranged at the top of hydraulic cylinder.Bottom at hydraulic cylinder has backstay.The backstay outside is threaded.Fuel tap once on the hydraulic cylinder.The backstay outside has spiral.On the hydraulic cylinder lower plunger, have addendum cone.In the bottom of body one axle tube is arranged, be threaded on the inwall of sleeve pipe.Backstay is connect by screw thread mutually with axle tube.On a side of axle tube, have form.One holder is arranged at the bottom of axle tube.
Using method of the present utility model is: when the dismounting axle bearing, the semiaxis end is stretched in the axle tube, then firm banking and semiaxis bearing are connect with bolted.Observe addendum cone by form and whether aim at the semiaxis center.After aiming at, press the hydraulic cylinder upper plug with depression bar, make the addendum cone on the lower plunger push the semiaxis end gradually.At this moment, it is motionless to withstand bearing by the semiaxis bearing.And semiaxis progressively breaks away from the interference fit district on the semiaxis under the extruding of addendum cone, and bearing is come off from semiaxis.After treating that bearing unloads, turn oil return valve, make the expansion link retraction, break away from semiaxis.Cause according to the different in size of different automobile types semiaxis, the screw thread that can adopt backstay to combine with axle tube is regulated operating distance, to satisfy the use of different size semiaxis.The utility model is simple in structure, and is reasonable in design, very convenient quick for the dismounting of axle bearing, can be used as the specific purpose tool of automobile axle shaft bearing removal.Fundamentally solved the difficult problem of axle bearing dismounting.Be not only convenient and swiftly, and safe and reliable, can not cause any damage miscellaneous part.
