The utility model adopts the above structure, have following advantage: 1, raise the lead screw through hollow hydraulic jack hydro -cylinder, drive and promptly fill up the pressure transmission to bearing inner race, the bearing inner race that raise, dismantle in following the gear with the bearing, avoided dismantlement in -process counter gear bearing to cause the damage, 2, the cross -section of the outer wall of supporting seat is the inclined plane, and the effect is guaranteed to draw not lead to the supporting seat to warp when getting the bearing.
Description
Technical field
The utility model relates to a kind of mining wheel side gear bearing dismounting tool.
Background technology
Mine truck in use, because stope slope sharp bend is anxious, often cause mine truck to take turns side gear to damage, when more gear changing owing to lacking specific purpose tool, two dish roller bearings often on dish gear and two jump rings are just dismantled not get off, even if destroy a dish with gas cutting another dish to be disassembled, to needing the bearing of dismounting also can bring certain damage in gas cutting process becomes, employ the bearing disassembled by Methods of OFC-A, vehicle bearing when the large turning of heavy load is easily cracked, brings great potential safety hazard to trouble free service.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of mining wheel side gear bearing dismounting tool, to reach object bearing being avoided when gear disassembling gets off damage of the bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of mining wheel side gear bearing dismounting tool, the elevating mechanism comprising supporting mechanism, stretch in dead eye the grasping mechanism be pressed on bearing, pulled out in gear by bearing to bearing transmission of pressure by grasping mechanism, described grasping mechanism is connected with described elevating mechanism.
Described elevating mechanism comprises hollow hydraulic jack, and described hollow hydraulic jack comprises jack cylinder, hydraulic top piston, screw mandrel, and described jack cylinder is provided with oil-in and oil return opening.
Described supporting mechanism comprises supporting seat, and described supporting seat upper surface is connected with jack cylinder, and the lower surface of supporting seat is extended with and withstands on gear face upper annular feet.
The cross section of the outer wall of described supporting seat is inclined-plane.
Described grasping mechanism comprises grasping pad, and the upper surface of described grasping pad is provided with the step surface structure be pressed on described bearing inner race.
Described screw mandrel is through described supporting seat, and described screw mandrel upper end is connected with described hydraulic top piston, and screw mandrel lower end is connected with described grasping pad.
Described screw mandrel upper end is connected with described hydraulic top piston by nut check.
The utility model adopts said structure, have the following advantages: 1, by hollow hydraulic jack cylinder, screw mandrel is risen, drive grasping pad that the pressure of rise is delivered to bearing inner race, bearing outer ring, bearing is disassembled in gear, avoids in unloading process and damage is caused to gear-bearing; 2, the cross section of the outer wall of supporting seat is inclined-plane, and effect ensures supporting seat can not be caused to be out of shape when pulling bearing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structural representation of the utility model disengage gear bearing;
Fig. 2 is structural representation of the present utility model;
In Fig. 1 ~ Fig. 2,1, jack cylinder; 2, hydraulic top piston; 3, screw mandrel; 4, oil-in; 5, oil return opening; 6, supporting seat; 7, gear; 8, feet; 9, grasping pad; 10, bearing inner race; 11, nut; 12, bearing outer ring; 13, bearing ball; 14, the spacing interior jump ring of bearing.
Detailed description of the invention
A kind of mining wheel side gear bearing dismounting tool as shown in Fig. 1 ~ Fig. 2, the elevating mechanism comprising supporting mechanism, stretch in dead eye the grasping mechanism be pressed on bearing, pulled out in gear by bearing to bearing transmission of pressure by grasping mechanism, described grasping mechanism is connected with described elevating mechanism.
Elevating mechanism comprises hollow hydraulic jack, and hollow hydraulic jack comprises jack cylinder 1, hydraulic top piston 2, screw mandrel 3, and jack cylinder 1 is provided with oil-in 4 and oil return opening 5.Supporting mechanism comprises supporting seat 6, and supporting seat 6 upper surface is connected with jack cylinder 1, and the lower surface of supporting seat 6 is extended with and withstands on gear 7 end face upper annular feet 8.
The cross section of the outer wall of supporting seat 6 is inclined-plane, and supporting seat 6 can not be caused like this when pulling bearing to be out of shape.Grasping mechanism comprises grasping pad 9, and the upper surface of grasping pad 9 is provided with the step surface structure be pressed on bearing inner race 10.Screw mandrel 3 is through described supporting seat 6, and screw mandrel 3 upper end is connected with hydraulic top piston 2, and screw mandrel 3 lower end is connected with grasping pad 9.Screw mandrel 3 upper end is connected with hydraulic top piston 2 by nut 11 locking.Bearing also comprises bearing outer ring 12, bearing ball 13, the spacing interior jump ring 14 of bearing.
When using this frock, steel bowl in the dish bearing not needing to dismantle is taken out, grasping pad 9 is sidelong into, make the interior step of grasping pad 9 and steel bowl inner ring in bearing will be dismantled to coincide, and then screw mandrel 3 is passed between grasping pad 9 mesopore, and then successively supporting seat 6 is installed above, hollow hydraulic jack, finally with nut 11, their are locked integral, then give hollow hydraulic jack cylinder oil-in to pressure with manual hydraulic oil pump, make hydraulic top piston 2 increase and pull grasping pad 9 by screw mandrel 3, the ball of bearing is just in time pushed down in the outside of grasping pad 9, so just can by bearing-withdrawing out.
When bearing is coiled in dismounting first, because installing space limit, lower flat mat thickness is wanted appropriateness and will be done point cuttings such as opposite side to it, not so installs to enter.Must, with interior steel bowl by bearing ball positioning supports, prevent from drawing ball displacement in the process of unloading to cause bearing damage when bearing is coiled in dismounting first.During assembly and disassembly instrument, first steel bowl in dismantled bearing is taken out, the grasping pad 9 of band step surface is placed between two dish bearings, locate by interior steel bowl reinstall and with boss again and coincide, from lower, screw mandrel 3 is penetrated again, supporting seat 6, hollow hydraulic jack, grasping pad 9 pinning with nut 11 are installed one by one above dismantled bearing.
Manual pump oil pipe is connected with jack slowly to power, is exerted a force to bearing outer ring by steel bowl and roller in bearing with plain cushion, pull-out bearing.Necessarily slowly giving pressure when exerting pressure to hollow hydraulic jack, strengthening again to surging after waiting bearing's looseness.Meeting the bearing of dismounting tension, manual pump hypertonia (watching by the Pressure gauge be contained on manual pump), do not dismantle by force, first by checking the reason being difficult to dismantle after jack pressure release, will can continue operation.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that the technical solution of the utility model is carried out; or directly apply to other occasion, all within protection domain of the present utility model without improving.
