Abstract
The utility model relates to a bearing dismantling device, in particular to a thin-wall deep-groove ball bearing dismantling device, which solves the problem that an existing thin-wall deep-groove ball bearing dismantling tool is easy to damage bearings. The dismantling device comprises a support, a hydraulic cylinder and a screw stem, wherein the hydraulic cylinder is fixed on the support, and the screw stem is driven to move vertically by the hydraulic cylinder. A rotary disc, a circular cover plate and a circular bottom plate are sequentially sleeved on the screw, and nuts respectively arranged on the lower portion of the circular bottom plate and the rotary disc are screwed on the screw stem. Tie plates are uniformly distributed between the circuit cover plate and the circular bottom plate, and each tie plate is composed of a plate and a clamp post on the plate. The circular cover plate is provided with radial clamping slots in the amount the same with the tie plates, the rotary disc is provided with inclined arc slots in the amount the same with the tie plates and distributed around the screw stem, and the clamp posts on the tie plates penetrate through the radial clamping slots on the circular cover plate and the inclined arc slots on the rotary disc. The dismantling device is used for dismantling thin-wall deep-groove ball bearings and is convenient in operation and capable of increasing working efficiency.
Description
Technical field
The utility model relates to bearing disassembling device, is specially the provision for disengagement of thin-walled deep groove ball bearing.
Background technology
The dismounting of bearing cooperates differently according to bearing and axle or bearing chamber, stress point is different.When cooperating with axle, stress point is bearing inner race and rotating shaft during dismounting; When cooperating with bearing chamber, stress point is bearing outer ring and bearing block during dismounting.
According to above content, (its mounting structure in workpiece as shown in Figure 1 for the thin-walled deep groove ball bearing, among the figure, 21 is the thin-walled deep groove ball bearing, and 22 is workpiece, and 23 is lip type rubber seal) dismounting, its stress point should be bearing outer ring and bearing block, but because its structure is special, rib is arranged itself and have only the 1mm gap with bearing inner race, it is infeasible adopting the method for existing hydraulic press pressure pad piece (according to bearing outer ring size and workpiece depth design).At present, during dismounting thin-walled deep groove ball bearing, adopt some custom-designed extracting tools, but these tool bearing forces points are bearing inner races, stress point is unreasonable; Dismantle by percussion hammer impact tool root, removal force is not steady; People's hand can not guarantee instrument and BEARING SHAFT level, bearing off-centre when causing dismantling easily.These factors all can cause damage of the bearing.
Summary of the invention
The utility model solves the problem that existing thin-walled deep groove ball bearing extracting tool can cause damage of the bearing, and the provision for disengagement of a kind of thin-walled deep groove ball bearing is provided.
The utility model is to adopt following technical scheme to realize: the provision for disengagement of thin-walled deep groove ball bearing, comprise support, be fixed on the support hydraulic cylinder and by Driven by Hydraulic Cylinder screw rod moving up and down, be with rotating circular disk on the screw rod successively, circular cover and circular bottom plate, also be screwed with the nut that lays respectively at circular bottom plate bottom and rotating circular disk top on the screw rod, between circular cover and circular bottom plate, be evenly equipped with arm-tie, arm-tie is made of the card post on plate body and the plate body, the radially draw-in groove identical with arm-tie quantity arranged on the circular cover, have identical with the arm-tie quantity tilting deep-slotted chip breaker that distributes around screw rod on the rotating circular disk, the card post on the arm-tie passes radially draw-in groove on the circular cover and the tilting deep-slotted chip breaker on the rotating circular disk.During use, with the edge of stent support in workpiece, the nut on rotating circular disk top is upwards rotated, the Driven by Hydraulic Cylinder screw rod moves down, make circular bottom plate, circular cover and the arm-tie between them stretch into bearing inner race, rotate rotating circular disk, the radially draw-in groove of card post on the arm-tie on the circular cover of the driving lower edge of the tilting deep-slotted chip breaker on the rotating circular disk outwards moves, make arm-tie stretch out circular bottom plate and circular cover, and stretch in the end play of bearing and workpiece, the nut on rotating circular disk top is rotated, and with rotating circular disk, circular cover and circular bottom plate compress the location, the Driven by Hydraulic Cylinder screw rod moves up, and the thin-walled deep groove ball bearing is pulled out in workpiece.Rotating circular disk is adjusted the distance that arm-tie stretches into the gap, and screw rod transmits pressure and guarantees pressure shaft core position (cover plate and base plate all have centre bore), and support makes hydraulic cylinder that reliable stress point be arranged, and hydraulic cylinder guarantees the pressure uniform and stable.
Thin-walled deep groove ball bearing described in the utility model provision for disengagement, structural design by rotating circular disk, collapsible arm-tie and hydraulic cylinder, solve bearing and disassembled the stressed difficulty in process middle (center) bearing outer ring, the jiggly problem of removal force, especially rotating circular disk can be adjusted the outreach of arm-tie, both guarantee bearing outer ring stress surface maximum, also made things convenient for operation, improved operating efficiency.

The specific embodiment
The provision for disengagement of thin-walled deep groove ball bearing, comprise support 1, be fixed on the support 1 hydraulic cylinder 2 and by Driven by Hydraulic Cylinder screw rod 3 moving up and down, be with rotating circular disk 4 on the screw rod 3 successively, circular cover 5 and circular bottom plate 6, also be screwed with the nut 7 that lays respectively at circular bottom plate bottom and rotating circular disk top on the screw rod 3, between circular cover 5 and circular bottom plate 6, be evenly equipped with arm-tie 8, arm-tie 8 is made of the card post 9 on plate body and the plate body, the radially draw-in groove 10 identical with arm-tie quantity arranged on the circular cover 5, have identical with the arm-tie quantity tilting deep-slotted chip breaker 11 that distributes around screw rod on the rotating circular disk 4, the card post 9 on the arm-tie 8 passes radially draw-in groove 10 on the circular cover 5 and the tilting deep-slotted chip breaker 11 on the rotating circular disk 4.During concrete enforcement, described screw rod 3 can be connected with the piston rod of hydraulic cylinder or on the piston rod of hydraulic cylinder screw thread is set, to realize the driving of hydraulic cylinder to screw rod.Described support can be made into any shape, structure that is fit to be supported in the edge of work.During actual fabrication, the circular bottom plate bottom can not have nut, directly connects in screw flight and make circular bottom plate into, and this is the easiest constructional variant of expecting of the utility model.
