Abstract
The invention discloses a bearing disassembling disc. Pin are in clearance fit with a shaft holding box via hole to be inserted into holes of a shaft holding box, and two pins and a top rod are evenly distributed below a force bearing disc in a three-point manner; a cushion block, a jack and a top bearing device are sequentially arranged at the central position of the force bearing disc from bottom to top; the top bearing device is supported in the shaft holding box and is in contact with a bearing through short pins; and the upper end face of a top rod and the upper generatrix of the pins are located on the same plane. The shaft holding box only needs to be turned over one time by disassembling bearings at the two ends of the shaft holding box, bolts do not need to be mounted and dismounted, the pins can be easily pulled out and inserted in, and the whole process can be completed within 10 minutes; and the disc is simple in structure and convenient to operate, the working efficiency can be effectively improved, and the labor intensity of workers is relieved.
Description
Technical field
The present invention relates to railway locomotive disintegration dismounting special process equipment technology field, is that dish disassembled by a kind of bearing specifically.
Background technology
During train wheel overhaul, in order to reach the requirement of flaw detection and maintenance, must disintegrate to axle suspension bearing box comprehensively.Axle suspension bearing box bearing is split type conical surface roller bearing, is railway special product.When axletree and axle suspension bearing box decompose, bearing inner race decomposes with axletree, and bearing outer ring is placed in axle suspension bearing box seam.Axle-hang box is designed with uniform three grooves below bearing outer ring, for insertion short pin dismounting bearing.When dismantling bearing outer ring, jack acts on apical axis bearing apparatus below, is moved upward, eject bearing outer ring by the short pin in apical axis bearing apparatus.Jack upwards pushes up, and a force bearing disk must be had under it to carry out supporting role power.At present, be adopt the force bearing disk mode be bolted in axle suspension bearing box end to carry out supporting role power.During dismounting bearing, fallen by axle suspension bearing box, force bearing disk eight M12 bolts are connected on axle-hang box end face, are then erected by axle suspension bearing box, under force bearing disk is placed in axle suspension bearing box, put cushion block, jack and apical axis bearing apparatus successively well, pressure jack dismounting bearing; During dismounting other end bearing, cushion block, jack and apical axis bearing apparatus need be taken out successively, axle suspension bearing box was fallen, pull down force bearing disk, then force bearing disk is connected to the other end of axle-hang box with eight M12 bolts, axle suspension bearing box is erected, put into cushion block, jack and apical axis bearing apparatus, dismounting bearing.After completing, take out cushion block, jack and apical axis bearing apparatus, then axle suspension bearing box was fallen pull down force bearing disk.Dismounting diaxon commitments need 40 minutes, and driving can not be left substantially.And the groundwork amount dismantling bearing installs and removes force bearing disk exactly, there is length consuming time, labor strength is large, operating process trouble is complicated, take the defects such as driving resource is many.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of bearing to disassemble dish, to reduce labor intensity, increases work efficiency.
The object of the present invention is achieved like this: dish disassembled by bearing, in pin and axle-hang box, via hole matched in clearance is inserted in the hole of axle suspension bearing box, under two pins and push rod 3 are distributed in force bearing disk, cushion block, jack, apical axis bearing apparatus are placed in the center on force bearing disk successively from bottom to up, apical axis bearing apparatus is supported on by short pin and bearing touch in axle suspension bearing box, and the upper surface of push rod and the Up Highway UHW of pin are at same plane.
The present invention utilizes the via hole of axle suspension bearing box to insert two pins, then adds a push rod, forms supported at three point force bearing disk, dismounting axle suspension bearing box bearings at both ends only needs once inside out axle suspension bearing box, without the need to installing and removing bolt, light plug pin, whole process can complete in 10 minutes, can avoid installing and removing bolt in a large number, upset axle suspension bearing box, structure is simple, easy to operate, and driving is very short for service time, effectively can increase work efficiency, alleviate labor strength.
Accompanying drawing explanation
Fig. 1 is structural representation sketch of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in drawings, dish disassembled by bearing, push rod 1 directly stands up in operation table top, pin 2 and axle suspension bearing box 8 to cross interporal lacuna be 1MM, easily plug pin 2, two pins 2 and push rod 1 three can be distributed in the force bearing disk 3 times that thickness is 15MM band journal stirrup, the upper surface of push rod 1 and the Up Highway UHW of pin 2 are at same plane, 3 roughly uniform, makes force bearing disk 3 level, and force bearing disk 3 can carry the reaction force that jack 5 ejects bearing; The general jack 5 of the cushion block 4 of transmitting forces, 20T, apical axis bearing apparatus 6 are placed in the center on force bearing disk 3 successively from bottom to up, apical axis bearing apparatus 6 is supported in axle suspension bearing box 8 and is contacted with bearing 9 by short pin 7, apical axis bearing apparatus 6 is a disk, at uniform three squares of circumference soldering, have circular hole in square, apical axis holds short pin 7 in circular hole slidably.
During dismounting bearing, pressure jack 5, the upper end face of jack 5 stretches out, and the short pin 7 in apical axis bearing apparatus 6 moves up for 9 times at bearing with device, releases bearing 9; During dismounting other end bearing, take out whole device, upset axle suspension bearing box 8, repeats last action.Dismounting bearings at both ends only need overturn axle suspension bearing box 8 once, can complete in 10 minutes.
Claims (2)
1. dish disassembled by bearing, it is characterized in that: pin (2) and axle suspension bearing box (8) via hole matched in clearance are inserted in axle suspension bearing box (8), under two pins (2) and push rod (1) three are distributed in force bearing disk (3), cushion block (4), jack (5), apical axis bearing apparatus (6) are placed in the center on force bearing disk (3) successively from bottom to up, and apical axis bearing apparatus (6) is supported on axle suspension bearing box (8) and is contacted with bearing (9) by short pin (7).
