The utility model discloses a solve the technical scheme that above-mentioned technical problem took and be:

the utility model provides a bearing detacher, includes baffle, push away an axle device, two flat boards and two pull rods, and processing has the semicircle orifice on every flat board, and two flat boards are together fixed with the detachable mode and form the arm-tie, and two semicircle orifices coincide on the arm-tie face and form a round hole, and the arm-tie passes through two pull rods and baffle fixed connection, is equipped with the push away an axle device that is used for pushing up the axle on the baffle.

Preferably, the push shaft device is a jack.

Preferably, the ejector rod of the jack is concentrically arranged with the bearing.

Preferably, a bearing dismounting device, still include two connecting blocks, be equipped with the notch on every connecting block, be equipped with the arch in two dull and stereotyped lock department both sides, the arch of two dull and stereotyped both sides is pegged graft in the notch of connecting block, is equipped with the through-hole that runs through the notch on every connecting block, is equipped with the bolt that is used for two fixed flats in the through-hole.

Preferably, each tie rod is threadedly connected to each connecting block.

Preferably, each plate has a thickness of less than 28 mm.

Compared with the prior art, the utility model following beneficial effect has:

the utility model discloses a push away the tip that the axle device pushed up at the axle to provide the axial force, exert reverse pulling force to the bearing inner race through the arm-tie, avoid traditional three-jaw bearing puller to dismantle the in-process of bearing inner race atress, destroy the problem of bearing holder or sealing ring easily. Meanwhile, after the bearing is assembled, the gap between the bearing and the inner cover is narrow, the detachable pulling plate is arranged, and the bearing detacher can be placed into the gap according to the plates with different thicknesses arranged in the gap between the bearing and the inner cover to detach the bearing.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.

Example 1: the embodiment is described below with reference to fig. 1 and 2, and the embodiment relates to a bearing dismounting device, which includes a baffle 1, a push shaft device 2, two flat plates 3 and two pull rods 4, wherein a semicircular hole is processed on each flat plate 3, the two flat plates 3 are detachably fixed together to form a pull plate, the two semicircular holes on the surface of the pull plate are matched to form a circular hole, the pull plate is fixedly connected with the baffle 1 through the two pull rods 4, and the baffle 1 is provided with the push shaft device 2 for pushing a push shaft 6.

In order to facilitate the disassembly of the bearing 7, the shaft pushing device 2 can be a jack, which enables the pulling plate to generate an acting force opposite to the shaft 6 during the disassembly process.

In order to facilitate the disassembly of the bearing 7, the pull plate generates an acting force opposite to the shaft in the disassembly process, and the ejector rod of the jack is arranged concentrically with the bearing. Optionally, one end of the shaft pushing device 2 is positioned at a stop opening of the baffle, and the other end of the shaft pushing device is arranged opposite to the shaft, so that deflection in the force application process is avoided.

For better two dull and stereotyped 3 locks of messenger and fixed connection together, this example still includes two connecting blocks 5, is equipped with the notch on every connecting block 5, is equipped with the arch in two dull and stereotyped 3's lock department both sides, and the arch of two dull and stereotyped 3 both sides is pegged graft in the notch of connecting block 5, is equipped with the through-hole that runs through the notch on every connecting block 5, is equipped with the bolt or the stud that are used for two fixed dull and stereotyped 3 in the through-hole. When the bearing 7 is disassembled, the two flat plates 3 are firstly placed in a space between the bearing 7 and the inner cover 8 and are fixed through the connecting block 5 through bolts or studs, and the shaft 6 is pushed by the shaft pushing device 2, so that the shaft 6 and the bearing 7 move mutually to be disassembled.

To facilitate assembly and disassembly, each tie rod 4 is optionally screwed to each connecting block 5. And one side of each pull rod 4, which is opposite to the threaded connection of each connecting block 5, is provided with an external thread and a boss, a through hole is processed in the baffle plate 1, and each pull rod 4 penetrates through the through hole of the baffle plate 1 to enable the baffle plate 1 to be clamped on the boss and fastened through a nut.

In order to allow the pulling plate to be placed in the space of 28mm between the bearing 7 and the inner cover 8, the thickness of each plate 3 is less than 28 mm.

Although the present invention has been described in detail with reference to certain specific embodiments, it will be understood by those skilled in the art that the foregoing examples are for purposes of illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
