Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
Example 1
As shown in fig. 1-3, a device for dismounting a bearing for reducing bearing damage includes a bearing seat 2, a bearing groove is formed on the outer surface of the bearing seat 2, a bearing member 3 is disposed in the bearing groove, an auxiliary gasket 4 is disposed between the bearing member 3 and the bottom of the bearing groove, a hole is formed in the middle of the auxiliary gasket 4, a jack groove is formed in the hole wall, a rod member 1 is inserted between the bearing member 3 and the auxiliary gasket 4, a cavity is disposed inside the rod member 1, a bottom rod 11 is disposed in the cavity, a top plate 13 is movably connected to the lower end of the bottom rod 11, a compression post 6 is fixedly connected to the outer surface of the upper end of the bottom rod 11, a hole 12 is formed in the outer surface of the rod body 1, when the compression post 6 moves down, the lower end of the bottom rod 11 moves down, the top plate 13 extends out of the hole 12 and enters the jack groove, the number of the top plate 13 is two, and, when the top plates 13 are arranged, it should be noted that the top plates 13 cannot move freely until the opposite surfaces of the two top plates 13 contact with each other, that is, the two top plates 13 cannot be perpendicular to the bottom of the rod 1, so as to prevent the rod from being locked when in use, and therefore, a movable joint with a limiting piece can be adopted.
The compression column 6 is a threaded column, the position state of the top plate 13 is convenient to regulate and control by using the threaded column, and the threaded column is in threaded connection with the inner surface of the rod piece 1; the outer surface of the lower end of the compression column 6 is fixedly connected with a connecting rod 7, the lower end of the connecting rod 7 is movably connected with a rotating rod 8, and the connecting rod 7 is connected with a bottom rod 11 through the rotating rod 8; a limiting clamping block 9 is fixedly connected to the outer surface of the side wall of the bottom rod 11, a limiting groove block 10 is fixedly connected to the inner surface of the rod piece 1, a limiting groove is formed in the outer surface of the limiting groove block 10, and the limiting clamping block 9 is located in the limiting groove and moves up and down; the outer surface of the upper end of the compression column 6 is fixedly connected with a top plate 5.
In use, as shown in fig. 3, the bearing removing device for reducing bearing damage first inserts the rod body 1 into the inner hole of the bearing piece 3 in the bearing seat 2, and the bottom of the auxiliary gasket is left in a hole arranged on the surface of the middle part of the auxiliary gasket 4, at the moment, the top plate 5 can be pressed by hands to select the pressing column 6, so that the pressing column 6 rotates and moves downwards, due to the matching action of the rotating rod 8, the limiting clamping block 9 and the limiting groove block 10, the bottom rod 11 drives the movable connecting end of the top plate 13 to move downwards, the other end of the top plate 13 extends out of the position of the outlet hole 12 and is inserted into the jacking groove on the side wall of the auxiliary gasket 4, and then the whole device is pulled up, the up-down distance of the jack-up notch in actual installation should be adjusted to the size of the top plate 13 which can slide into, too large will increase the thickness of the auxiliary gasket 4, and too small may affect the insertion effect of the top plate 13.
