[0019] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with the concrete implementing method.
[0020] In the description of the utility model, it needs to be explained that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "another end" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not indicative or suggestive of the device or element being indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicative or suggestive of relative importance.
[0021] The utility model discloses a kind of adjustable motor bearing stripping devices, the device is used to strip the bearing of motor from shaft, in use, cooperate with hydraulic press and other power device,
[0022] As Figure 1As shown, the device comprises a first top plate 1 and a second top plate 2. The first top plate 1 and the second top plate 2 are arranged at a distance apart, and both are parallel. Threaded holes are arranged on the surfaces of the first top plate 1 and the second top plate 2, and then the first top plate 1 and the second top plate 2 are connected by a screw rod 3. Since the screw rod 3 is arranged for connection, the relative distance between the first top plate 1 and the second top plate 2 can be adjusted by moving on the screw rod 3.
[0023] The first top plate 1 and the second top plate 2 are generally rectangular steel plates.
[0024] The device also needs to arrange a slot hole 4 on the first top plate 1. The first top plate 1 and the second top plate 2 are rectangular steel plates. Preferably, the shape of the slot hole 4 is a circular segment that can be roughly matched with the bearing.
[0025] In order to facilitate the assembly of the screw rod 3 with the first top plate 1 and the second top plate 2, a handle can be arranged at one end of the screw rod 3, or a square head or a hexagonal head can be arranged; it is convenient to rotate the screw rod 3.
[0026] In the specific implementation of the utility model, preferably, two screw rods 3 are arranged to ensure stable connection.
[0027] The device can be in a separated and disassembled state of the first top plate 1, the second top plate 2 and the two screw rods 3 in the non-use state, and can be quickly assembled in use. The first top plate 1 can be pre-processed in multiple ways, mainly different specifications of slot holes, and can be selected and used as needed when disassembling bearings of different specifications.
[0028] The first top plate 1 needs to be cut by 3 / 4 circular chord to form a slot hole. The size of the cutting circle is determined according to the bearing diameter and the shaft diameter. The diameter of the cutting circle should be less than the bearing diameter and greater than the shaft diameter, and the chord length should be slightly greater than the shaft diameter. For example: the maximum diameter of the bearing is 80mm, and the shaft diameter is 60mm, so the diameter of the cutting circle should be less than 80mm and greater than 60mm, and the chord length should be slightly greater than 60mm.
[0029] When the device is used, the bottom of the hydraulic machine is placed in the inner side of the second top plate 2. The bearing to be disassembled is placed in the inner side of the first top plate 1. In order to ensure the installation of the parts, a rubber pad is placed between the shaft head and the hydraulic machine shaft head. Then, the bearing on the shaft can be removed by the pressure of the hydraulic machine. According to the diameter of the shaft head, the corresponding size of the rubber pad is selected. The selection of the portable hydraulic machine should be determined according to the actual situation.
[0030] The utility model can be conveniently and quickly used to disassemble the bearing from the shaft, and through the replacement and adjustment of the top plate, the disassembly of various different types of motor bearings can be realized, and one machine can be used for multiple purposes.
