Abstract
The utility model discloses a tool for bearing outer ring disassembling. A bearing clamping mechanism comprises a mounting seat. Clamping jaws hinged to the mounting seat comprise tip parts and matching parts. A screw rod is further arranged on the mounting seat. The matching relation of the screw rod and the clamping jaws is that when the screw rod is screwed into the mounting seat, the end portion of the screw rod abuts against the matching parts of the clamping jaws and pushes the clamping jaws to rotate to make the tip parts stretch. The two clamping jaws are arranged on the mounting seat first, then the screw rod is screwed into the mounting seat, the screw rod is not completely screwed in at first in order to prevent the clamping jaws from bearing force, the tip parts of the clamping jaws naturally hang down under the state of the self gravity of the clamping jaws, at this time, the whole clamping mechanism penetrates through a bearing, the screw rod is tightly screwed slowly clockwise, the clamping jaws are pushed through the screw rod, so that the clamping jaws deviate along rotating shafts, the tip parts of the clamping jaws tilt and are in contact with the bottom of an outer ring of the bearing, and accordingly the outer ring of the bearing can be clamped, a stable supporting point is provided for disassembling of the outer ring of the bearing, and the outer ring of the bearing can be easily disassembled.
Description
Technical field
The utility model relates to the Vehicle Engineering field, more precisely, relates to a kind of frock for the bearing outer ring dismounting.
Background technology
Double-clutch speed changer is different from general automatic transmission system, and the flexibility of existing manual transmission has the comfortableness of automatic transmission again, and unremitting power output can also be provided.
Double-clutch speed changer is a kind of new technique, in Development and Trial and process of the test, often need carry out the improvement of experimental technique scheme and disassemble analysis model machine or exemplar, the normal cone bearing that uses is as preloaded bearing in the DCT gearbox, and bearing outer ring is common and housing takes the interference mode to press-fit, therefore bearing outer ring is very difficult in disassembling process, even can't disassemble, have a strong impact on the checking exploitation of DCT gearbox; Therefore, designing a kind of frock of disassembling for bearing outer ring and solve the problem that bearing outer ring is difficult to disassemble, is that those skilled in the art are badly in need of the technical problem that solves at present.
The utility model content
The utility model is in order to solve the problem that the bearing outer ring that exists in the prior art is difficult to disassemble, and a kind of frock of disassembling for bearing outer ring is provided.This frock can make disassembling of bearing outer ring become simple and reliable, guarantees to disassemble in the process can not damage exemplar, has avoided the people to take failure mode to disassemble influence to product quality.
In order to solve the above problems, the technical solution of the utility model is: a kind of frock of disassembling for bearing outer ring, comprise the bearing clamping device, and described bearing clamping device comprises mount pad, be articulated with a plurality of jaws on the described mount pad, described jaw comprises a point and auxiliary section; Also be provided with a screw rod on the described mount pad, the matching relationship of described screw rod and jaw is: screw in the process of mount pad at screw rod, described screw rod has an end to be withstood the auxiliary section of jaw and promotes jaw and rotate the open process of point that makes.
Preferably, the cross section of described mount pad is inverted U-shaped, and two jaws are assemblied in the two ends of mount pad sidewall respectively symmetrically by rotating shaft; A screw rod is assembled by screw in the top of described mount pad.
Preferably, comprise that also one is supported on the bracing or strutting arrangement on the bearing block, the bracing frame of described bracing or strutting arrangement for passing for screw head.
Preferably, support frame as described above is one to be supported on the stop sleeve on the bearing block, and the screw end head that passes stop sleeve is provided with clamp nut, and this clamp nut is set to, and under the effect of a torque, the screw rod on the bearing clamping device is drawn out.
Preferably, also be provided with observation window on the described stop sleeve.
The concrete assembling of the utility model frock, course of action are as follows:
At first two jaws are installed on the mount pad, then lock locking nut, then screw rod is screwed into mount pad, earlier be not screwed into screw rod fully to avoid jaw stressed, make jaw sagging naturally at the point of jaw under the state of gravity, the jaw on the frock is not when being subjected to the thrust of screw rod, and the point of gravitate jaw can let droop by nature, because cam is sagging to diminish the pivot angle between two jaws, thereby whole bearing clamping device is placed among the bearing outer ring like a cork.
Pass bearing with whole clamping device this moment, slowly screw screw rod clockwise, promoting jaw by screw rod makes jaw deflect along rotating shaft, make the point perk of jaw and touch the bottom of bearing outer ring, thereby bearing outer ring can be clamped, for the dismounting of bearing outer ring provides a stable fulcrum, so that bearing outer ring is removed like a cork.
Frock of the present utility model also provides clamp nut and stop sleeve, when clamp nut and screw rod screw, act on moment process screw rod and clamping device on the stop sleeve, finally the point by jaw is delivered to the bearing outer ring bottom, and the pressure that clamp nut screws is transformed into the pulling force of housing washer, along with the continuous increase of moment will progressively overcome the magnitude of interference between bearing outer ring and the bearing block, bearing outer ring is disassembled smoothly the most at last.

The specific embodiment
For the technical problem that the utility model is solved, the technical scheme of employing, the technique effect of obtaining should be readily appreciated that, below in conjunction with concrete accompanying drawing, the specific embodiment of the present utility model is described further.
The utility model provides a kind of frock of disassembling for bearing outer ring, and this frock can make disassembling of bearing outer ring become simple and reliable, guarantees to disassemble in the process can not damage exemplar, has avoided the people to take failure mode to disassemble influence to product quality.
With reference to figure 1, Fig. 2, Fig. 3, in a kind of concrete embodiment, the utility model provides a kind of frock of disassembling for bearing outer ring, comprise that as the stop sleeve 1 of bracing or strutting arrangement (can be a bracing frame) also comprise screw rod 2, the head of screw rod 2 passes stop sleeve 1, screw rod 2 heads are furnished with a clamp nut 7, in the process that turns this clamp nut 7, clamp nut 7 acts on the moment on the stop sleeve when screwing with screw rod 2, makes screw rod 2 outwards mobile.
The cross section is on the mount pad 3 of inverted U-shaped and offers two installing holes, and two jaws 4 are installed on the sidewall of mount pad 3 symmetrically by rotating shaft 5 respectively, and the other end of two rotating shafts 5 is equipped with two locking nuts 6 and prevents rotating shaft 5 lax or plaies.The quantity of the utility model jaw 4 can also be three, and at this moment, mount pad 3 is cylindrical, and three jaws are articulated in the breach that the mount pad sidewall offers equidistantly.Certainly according to those skilled in the art's understanding, the quantity of jaw 4 can also be four or more.
