Abstract
The invention discloses a bearing dismounting device, which comprises clamping plates and pulling plates, wherein each clamping plate comprises an outer clamping plate on the outer side and an inner clamping plate on the inner side; a semicircular hole is formed in the middle of the clamping plate, a semicircular hole is correspondingly formed in the middle of the backing plate, and the inner diameter of the semicircular hole is larger than the outer diameter of the shaft and smaller than the outer diameter of the bearing; the backing plate, the clamping plate and the pulling plate are all provided with strip holes, and after the tensioning bolt penetrates through the strip holes, the backing plate and the pulling plate are fixed by nuts at the outer sides; a round through hole is formed in the middle of the pulling plate, and a jacking bolt penetrates through the round through hole and then abuts against the end face of the shaft. The invention has the advantages that: because the adjustable clamping plate structure is adopted, the motor shafts with different diameters can be disassembled, and therefore the universality is strong; in addition, the invention has simple structure, low cost and good use effect.
Description
Technical Field
The invention relates to the field of machinery, in particular to a dismounting device.
Background
When the motor bearing needs to be disassembled during maintenance, and after the outer ring, the inner ring and the retainer of the bearing are seriously deformed, a normal hydraulic puller cannot be used, and only water is used for electric welding cutting, so that a motor shaft is extremely easy to damage.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a device which can conveniently disassemble a motor shaft, can disassemble the motor shaft aiming at motor shafts with different diameters and has strong universality; the specific technical scheme is as follows:
a bearing dismounting device comprises clamping plates and pulling plates, wherein each clamping plate comprises an outer clamping plate on the outer side and an inner clamping plate on the inner side, each outer clamping plate is provided with a threaded through hole, and an adjusting bolt penetrates through the threaded through hole and then is screwed with the threaded blind hole of the inner clamping plate; a semicircular hole is formed in the middle of the clamping plate, a semicircular hole is correspondingly formed in the middle of the backing plate, and the inner diameter of the semicircular hole is larger than the outer diameter of the shaft and smaller than the outer diameter of the bearing; the backing plate, the clamping plate and the pulling plate are all provided with strip holes, and after the tensioning bolt penetrates through the strip holes, the backing plate and the pulling plate are fixed by nuts at the outer sides; a round through hole is formed in the middle of the pulling plate, and a jacking bolt penetrates through the round through hole and then abuts against the end face of the shaft.
The two ends of the long hole on the clamping plate are respectively arranged on the outer clamping plate and the inner clamping plate.
And nuts are arranged on the two sides of the puller bolt, which are positioned on the pulling plate.
The invention has the advantages that: because the adjustable clamping plate structure is adopted, the motor shafts with different diameters can be disassembled, and therefore the universality is strong; in addition, the invention has simple structure, low cost and good use effect.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the card board.
Detailed Description
The invention is described in detail with reference to the accompanying drawings, as shown in the drawings, the invention comprises a clamping plate 1 and a pulling plate 2, wherein the clamping plate 1 comprises an outer clamping plate 9 at the outer side and an inner clamping plate 10 at the inner side, the outer clamping plate 9 is provided with a threaded through hole, an adjusting bolt 11 penetrates through the threaded through hole and then is screwed with a threaded blind hole of the inner clamping plate 10, and the adjusting bolt is locked by a nut 12; a semicircular hole 15 is arranged in the middle of the clamping plate 1 (the semicircular hole is actually a combination of a rectangular hole and the semicircular hole, the rectangular part is used for a shaft to pass through, the semicircular part is used for limiting the axial position of the bearing), a semicircular hole is correspondingly arranged in the middle of the backing plate 3, and the inner diameter of the semicircular hole is larger than the outer diameter of the shaft 6 and smaller than the outer diameter of the bearing 7; the backing plate 3, the clamping plate 1 and the pulling plate 2 are all provided with strip holes 14, and after the tensioning bolt 4 penetrates through the strip holes 14, the backing plate 3 and the pulling plate 2 are fixed by nuts II 8 on the outer sides; a round through hole is formed in the middle of the pulling plate 2, and the puller bolt 5 penetrates through the round through hole and then abuts against the end face of the shaft 6.
Two ends of the long hole 14 on the clamping plate 1 are respectively arranged on the outer clamping plate and the inner clamping plate.
And nuts are arranged on two sides of the puller bolt 5, which are positioned on the pulling plate.
In order to increase the universality, the diameter of the semicircular hole of the backing plate is larger than that of the semicircular hole of the clamping plate.
As shown in fig. 2, the two ends of the elongated hole 14 are rounded transition ends 13.
