Abstract
The utility model relates to the technical field of demounting devices, in particular to a demounting device for axle box bearings. The demounting device for the axle box bearings comprises a pressure plate, a rolling bearing, a gasket, a fixing plate, a ball screw, a handle and a sleeve. The pressure plate is connected to one end of the ball screw through the gasket, the fixing plate is arranged on the ball screw, the rolling bearing is arranged between the fixing plate and the pressure plate, the sleeve is arranged outside the ball screw, and the handle is arranged at the other end of the ball screw. The demounting device for the axle box bearings is simple in structure and can be used for removing the axle box bearings of locomotives easily as needed, scraping of the bearings caused by the fact that the bearings are knocked by tools such as copper rods can be avoided, and economical benefits can be brought to enterprises.
Description
Technical field
The utility model relates to a kind of provision for disengagement, relates in particular to a kind of provision for disengagement that is used for axle box bearing.
Background technology
Locomotive enters factory and keeps in repair; Need carry out the axle box bearing dismounting; But when the dismounting axle box bearing, do not have special-purpose extracting tool, the employee can only use copper rod, hammer that bearing is pounded out, and so almost every retainer that takes apart all can be damaged; Thereby cause bearing to be scrapped, also brought tremendous loss for enterprise.
Summary of the invention
The technical problem that the utility model will solve is: in the prior art; When the dismounting axle box bearing; The employee can only use copper rod, hammer that bearing is pounded out, and so almost every retainer that takes apart all can be damaged, thereby causes bearing to be scrapped; Also brought tremendous loss for enterprise, a kind of provision for disengagement that is used for axle box bearing is provided.
In order to overcome the defective that exists in the background technology; The utility model solves the technical scheme that its technical problem adopted: this provision for disengagement that is used for axle box bearing comprises pressing plate, rolling bearing, packing ring, fixed head, ball, handle and cover; Said pressing plate is through an end of packing ring connection ball-screw, and said ball-screw is provided with fixed head, is provided with rolling bearing between said fixed head and the pressing plate; Said ball-screw is provided with cover outward, and the other end of said ball-screw is provided with handle.
The beneficial effect of the utility model is: this provision for disengagement that is used for axle box bearing; It is simple in structure, repaiies in the locomotive when being used to dismantle axle box bearing, just can bearing easily be withdrawed from; Scrap situation thereby avoid beaing the bearing that bearing causes, brought economic benefit to enterprise with instruments such as copper rods.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Wherein: 1, pressing plate, 2, rolling bearing, 3, packing ring, 4, fixed head, 5, ball-screw, 6, handle, 7, cover.
The specific embodiment
Fig. 1 is the structural representation of the utility model; Comprise pressing plate 1, rolling bearing 2, packing ring 3, fixed head 4, ball-screw 5, handle 6 among the figure and overlap 7; Said pressing plate 1 is through an end of packing ring 3 connection ball-screws 5, and said ball-screw 5 is provided with fixed head 4, is provided with rolling bearing 2 between said fixed head 4 and the pressing plate 1; The said ball-screw 5 outer covers 7 that are provided with, the other end of said ball-screw 5 is provided with handle 6.
During use, pressing plate 1 placed in the axle box contact with bearing, fixed head 4 is fixed in outside the axle box, and rotary handle 6 drives ball-screw 5 and rotates, and the rotation of ball 5 just drives pressing plate 1 and rotates, and so just can easily withdraw from bearing.
This provision for disengagement that is used for axle box bearing simple in structure as long as easily withdraw from, scrapped situation thereby avoid beaing the bearing that bearing causes with instruments such as copper rods when being used for locomotive and repairing the dismounting axle box bearing, brought economic benefit to enterprise.
