Abstract
The utility model provides a bearing removing device for vehicle repairing industry. A hollow draw rod is provided with a pin. When the bearing-withdrawing tool is used, the pin is pushed out, and a bearing inner ring is pinned, so the bearing can be taken off easily. The utility model has the advantages of simple structure, portability, and high work efficiency, and is convenient to operate even in a very tiny operating space. The work efficiency can be increased by more than 10 times.
Description
The utility model relates to a kind of bearing extractor, particularly a kind of bearing extractor that is used for motor repair trade.
In motor repair trade, the engine crankshaft bearing of some vehicles is when changing, and is normally that a bearing and a pull bar is welded together, bearing taken off again.Repair work also will be carried out under vehicle body sometimes, because working space is little, and the difficulty when just more having increased dismounting.This method efficient is low, dangerous, also damage other part easily.
Task of the present utility model provides a kind of simple, light, saving of labor, labour-saving bearing extractor.
The utility model is finished as follows: adorning several on the hollow draw-bar can overlap opening wire spring circle along the pin that radially slides of hollow draw-bar on the pin, does not drop out and can shrink back to guarantee pin.A garden conical head bolt is adorned in hollow draw-bar inside, during work, hollow draw-bar is stretched into the inner ring of bearing, and rotation garden conical head bolt utilizes the conical surface of garden conehead, just pin can be ejected, and bearing is pinned, and bearing is taken out.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Below in conjunction with accompanying drawing in detail details of the present utility model is described in detail.
3 open-works are radially bored in same garden in hollow draw-bar (1) lower end on week, and cut out a cannelure, are adorning the pin (3) that can radially slide in the hole, adorn an opening wire spring circle (2) in the cannelure.The inside and outside screw thread that all processes of hollow draw-bar (1), garden conical head bolt (6) is contained in hollow draw-bar (1) lining.One of pin (3) is cone.Pin (3) can move along the radial direction of hollow draw-bar (1) under the effect of garden conical head bolt (6) and opening wire spring circle (2).The matrix cavity of platen (4) is greater than the bearing that is removed, and is enclosed within the outside of hollow draw-bar (1).Nut (5) is spun on the external screw thread of hollow draw-bar (1), screws nut (5) and just hollow draw-bar (1) and bearing can be pulled out.
The utility model part is few, and is simple in structure, easy and simple to handle, can improve more than work efficiency 10 trainings.
Claims (2)
1, a kind of bearing extractor of being made up of bolt, nut, gland, hollow draw-bar is characterized in that: the pin that has several to move in the radial hole of inside and outside threaded hollow draw-bar one end.
2, bearing extractor as claimed in claim 1 is characterized in that: an opening wire spring circle is arranged on the hollow draw-bar.
