Abstract
The utility model relates to a bearing dismantling tool, in particular to a special dismantling tool for the main drive gear bearing of the Meichi-bridge reducer. The bearing dismantling tool comprises a pressure plate and two clamping plates. The utility model is characterized in that the both sides of the two clamping plates are perforated with linking bolts, and the two clamping plates form a hole whose center diameter is slightly bigger than the outside diameter of the bearing; the end of the hole is provided with an inward flange which is matched with the space of the bearing and the gear shaft shoulder. The center of the pressure plate is provided with dismantling screws which dead face to the end face of the gear shaft, and the pressure plate and the clamping plates are connected and integrated by carrying bolts which are clamped between the two clamping plates. The utility model solves the dismantling problem that the space between the matched bearing and the shaft compression is small, and the bearing dismantling tool is simply manufactured and is time and labor-saving and safe and reliable.
Description
(1) technical field under
The utility model relates to a kind of bearing extractor, particularly a kind of speed specific purpose tool of bridge decelerator main drive gear bearing dismounting of U.S.A that is used for.
(2) background technology
U.S.A speeds, and driving gear shaft and bearing belong to interference fit in the bridge decelerator, and maintenance and be subjected to structural limitations when changing does not have the withdrawal space, and general extracting tool can't use, and causes the dismounting difficulty.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, and a kind of bearing extractor that bearing and gear shaft press-fit the back interference fit that is used to solve is provided.
The technical solution of the utility model is:
A kind of bearing extractor, comprise pressing plate and two clamping plates, its special character is: described two clamping plates both sides are penetrated with connecting bolt, two clamping plates form central authorities for be slightly larger than bearing outside diameter circular hole, there is inward flange the circular hole end, and the space of inward flange and bearing and the gear shaft shaft shoulder is suitable; The knockout screw that faces the gear shaft end face is equipped with in pressing plate central authorities, and pressing plate, clamping plate are connected as one by the bolt that is clipped in two clamping plate.
The utility model is to be stretched into the small space of the bearing and the gear shaft shaft shoulder and embraced bearing by two clamping plates, utilizes the spiral reinforcement principle, and knockout screw withstands on the gear shaft end face, and the rotation knockout screw drives pressing plate and clamping plate move simultaneously, and bearing is pulled down.
The utility model has solved bearing and axial compression and has cooperated the little dismounting problem of rear space, and it is simple to have a processing and manufacturing, uses advantages such as time saving and energy saving, safe and reliable.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 looks schematic diagram for a left side of the present utility model.
Among the figure, 1 clamping plate, 2 bolts, 3 pressing plates, 4 knockout screw, 5 connecting bolts, 6 gear shafts, 7 bearings, 8 circular holes, 9 inward flanges.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises pressing plate 3 and the two clamping plates 1 that roughly becomes cuboid, two clamping plates 1 both sides are connected and fixed with connecting bolt 5, two clamping plates 1 central authorities are extruded with inward flange 9 for being slightly larger than the circular hole 8 of bearing outside diameter around the circular hole 8, inward flange 9 is suitable with the space of the bearing 6 and gear shaft 6 shaft shoulders; The knockout screw 4 that faces circular hole 8 centers is equipped with in pressing plate 3 central authorities, and pressing plate 3 both sides are the bolt 2 of binding clip 1 and pressing plate 3.
Claims (1)
1. bearing extractor, comprise pressing plate (3) and two clamping plates (1), it is characterized in that: described two clamping plates (1) both sides are penetrated with connecting bolt (5), two clamping plates (1) form central authorities for be slightly larger than bearing (7) external diameter circular hole (8), there is inward flange (9) circular hole (8) end, and inward flange (9) is suitable with the space of the bearing (7) and gear shaft (6) shaft shoulder; The knockout screw (4) that faces gear shaft (6) end face is equipped with in pressing plate (3) central authorities, and pressing plate (3), clamping plate (1) are connected as one by the bolt (2) that is clipped in two clamping plate (1).
