Further, the method comprises the following steps of; the front side wall and the rear side wall of the semi-cylinder are spliced to form a row of connecting nuts, and the connecting nuts are in threaded connection with the fixing screws.

Further, the method comprises the following steps of; still including drawing the horse ware, it is located the support column top to draw the horse ware, it includes I shape backup pad, two set screw and jackscrew to draw the horse ware, the halfcylinder top is equipped with the jack, the jack is equipped with set nut outward, I shape backup pad center is equipped with the screw hole, screw hole threaded connection jackscrew, two set screw passes I shape backup pad left and right sides clearance back threaded connection set nut respectively and passes the jack.

Further, the method comprises the following steps of; and a base is arranged at the bottom of the supporting column.

The utility model has the beneficial effects that: the bearing dismounting device is simple in structure, applicable to dismounting the bearing of the small motor, simple in dismounting method, time-saving, labor-saving and multipurpose. The problems that three claws are not suitable to be placed, uneven in stress, time-consuming and labor-consuming and the like in the existing dismounting process of the puller are solved, and the working efficiency is greatly improved.

FIG. 3 is a schematic structural view of example 2.

In the figure: 1. a support pillar; 2. a bayonet; 3. a cushion pad; 4. a connecting nut; 5. fixing screws; 6. a base; 7. positioning a nut; 8. an I-shaped support plate; 9. two set screws; 10. carrying out top thread; 11. a semi-cylinder; 12. a bearing; 13. a rotating shaft.

Detailed Description

Example 1:

as shown in fig. 1 and 2, a small motor bearing detacher, includes support column 1, support column 1 is formed by two halfcylinders 11 concatenation, support column 1 is hollow structure, support column 1 top center is equipped with bayonet 2, the bottom is equipped with base 6. The semi-cylinder 11 is equipped with blotter 3 in bayonet socket 2 periphery, semi-cylinder 11 is equipped with a row of coupling nut 4 in front and back lateral wall concatenation department, 4 threaded connection set screws 5 of coupling nut.

The using method comprises the following steps: when a small bearing is disassembled, firstly the fixing screw 5 is unscrewed, the two half cylinders 11 are separated, the rotor with the bearing 12 passes through the bayonet 2, the bearing 12 is arranged above the cushion pad 3, then the fixing screw 5 is screwed, the supporting column 1 clamps the rotor rotating shaft 13, then the rotating shaft 13 is knocked by an iron hammer, and then the bearing 12 can be disassembled from the rotor rotating shaft 13, so that the purpose of disassembling the bearing 12 is achieved.

Example 2:

as shown in figure 3, a small motor bearing detacher, includes support column 1 and draws horse ware, support column 1 is formed by two halfcylinders 11 concatenations, support column 1 is hollow structure, 1 top center of support column is equipped with bayonet socket 2, the bottom is equipped with base 6. 11 tops of halfcylinder are equipped with the jack, the jack is equipped with set nut 7 outward, 11 tops of halfcylinder are equipped with blotter 3 in 2 peripheries of bayonet socket, halfcylinder 11 is equipped with a coupling nut 4 in front and back lateral wall concatenation department, 4 threaded connection set screws 5 of coupling nut.

The puller is located 1 top of support column, the puller includes I-shaped backup pad 8, two set screws 9 and jackscrew 10, 8 centers in I-shaped backup pad are equipped with the screw hole, screw hole threaded connection jackscrew 10, two set screws 9 pass 8 left and right sides clearances of I-shaped backup pad after threaded connection set nut 7 and pass the jack respectively.

When a smaller bearing is disassembled, the rotating shaft is deformed or damaged by knocking with an iron hammer due to the small rotating shaft, so that the disassembling method in the embodiment 1 is not suitable to be used, and the disassembling method in the embodiment is as follows: firstly, two positioning screws 9 are unscrewed from a positioning nut 7, a puller is disassembled, then the fixing screws 5 are unscrewed, two semi-cylinders 11 are separated, a rotor with a bearing 12 passes through a bayonet 2, the bearing 12 is arranged above a cushion pad 3, then the fixing screws 5 are screwed down, a rotor rotating shaft 13 is clamped by a support column 1, then the two positioning screws 9 are screwed on the positioning nut 7, the heads of the two positioning screws 9 are clamped above an I-shaped support plate 8, then a jackscrew 10 is screwed to be jacked at the top center of the rotating shaft 13, and screwing is continued until the bearing 12 is disassembled from the rotor rotating shaft 13, so that the purpose of disassembling the bearing 12 is achieved.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to be limiting in any way, and other variations and modifications are possible without departing from the scope of the utility model as set forth in the appended claims.
