Abstract
The utility model provides a motor belt wheel dismounting tool and relates to a machine repairing tool. The motor belt wheel dismounting tool comprises a pulling plate, screw rods, a top plate and a horizontal jack. The pulling plate is formed by detachably connecting two opposite semi-circular bodies through bolts, the two semi-circular bodies of the pulling plate are clamped on a motor output shaft, close to one side of a motor, of a belt wheel, corresponding coaxial through holes are evenly formed in the circumference of the pulling plate and the circumference of the top plate, the top plate is arranged on the side, far from the motor, of the belt wheel, the screw rods penetrate through the corresponding through holes in the pulling plate and the top plate, and the horizontal jack is arranged between the top plate and the belt wheel. The motor belt wheel dismounting tool has the advantages that work efficiency is improved, the shutdown time due to belt wheel replacing is reduced, the belt wheel is effectively prevented from being damaged in the dismounting process, construction procedures are simplified, labor intensity is reduced, the manufacturing process is simple, and the motor belt wheel dismounting tool is suitable for dismounting motor belt wheels of various types.
Description
Technical field
The utility model relates to a kind of mechanical maintenance tool in use, is specially a kind of motor pulley extracting tool.
Background technology
At present, what field stripping motor pulley was used is old-fashioned three-jaw pulley extractor, very easily causes rim of pulley fracture in pulling drum process.While using three-jaw pulley extractor to pull up old belt pulley, three pawls that can be by pulley extractor apply very large pulling force to belt pulley near a side flange of motor, due to the stressed sheave groove structure having with wheel rim place of concentrating, cause the wheel rim part that belt pulley contacts with three-jaw to be subject to very large tension, so castiron belt pulley is easy to occur fracture at wheel rim.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, can not damage belt pulley, easy to operate motor pulley extracting tool.
The technical scheme that realizes above-mentioned purpose is: motor pulley extracting tool, it is characterized in that: comprise arm-tie, screw mandrel, top board and Horizontal jack, arm-tie is provided with the centre bore matching with motor output shaft, and the centre bore of arm-tie is placed through on the output shaft between belt pulley and motor; Described arm-tie and the one group of through hole that is evenly equipped with corresponding concentric the ring week of top board; Top board is arranged at belt pulley away from motor one side, arm-tie and roof symmetric setting, in the corresponding through hole of arm-tie and top board, placed respectively screw mandrel, the nut that has been threaded respectively on the screw mandrel of arm-tie and top board outer end, Horizontal jack is placed between top board and belt pulley.
Optimally, the tail end of described Horizontal jack top is pressed on top board, and the top, working end of Horizontal jack is pressed on the output shaft of motor, Horizontal jack and motor output shaft concentric.
Optimally, described arm-tie is removably connected and is formed by bolt by two involutory semicircular body.
Optimally, described one group of through hole is distributed on the concentric circles of arm-tie and top board.
Optimally, many group through holes are set on described arm-tie and top board, organize on the concentric circles that through hole is arranged on arm-tie and top board different-diameter more.
During use, first two arm-ties are fastened on the motor output shaft of belt pulley inner side, with screw mandrel, be placed through in corresponding through hole, top board is connected with arm-tie, Horizontal jack is arranged between top board and belt pulley, the tail end top of Horizontal jack is pressed on top board, and the top, working end of Horizontal jack is pressed on the output shaft of motor, guarantees Horizontal jack, top board and motor output shaft concentric; Slowly start the hydraulic means of jack, belt pulley easily comes off from motor shaft under the drive of arm-tie.
The beneficial effects of the utility model:
1, improved operating efficiency, reduced because changing the downtime of belt pulley;
2, effectively avoided the damage at unloading process middle belt pulley;
3, simplify operational procedure, alleviated labour intensity;
4, manufacture craft is simple, is applicable to the dismounting of various model motor pulleys.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of arm-tie;
Fig. 3 is the structural representation of top board.
The specific embodiment
As shown in Figure 1, the utility model comprises arm-tie 1, screw mandrel 2, top board 3 and Horizontal jack 4, arm-tie 1 is removably connected and is formed by bolt 9 by two involutory semicircular body 7 and 8, arm-tie 1 is provided with the centre bore 5 matching with the output shaft of motor 6, two semicircular body 7 of arm-tie 1 and 8 be sticked on the output shaft of belt pulley 10 near the motor 6 of motor one side.
Arm-tie 1 be evenly equipped with some corresponding concentric through holes 11 the ring week of top board 3, top board 3 is arranged at belt pulley away from motor one side, arm-tie 1 is symmetrical arranged with top board 3, the interior screw mandrel 2 that placed respectively of corresponding through hole 11 of arm-tie 1 and top board 3, nut 12 has been threaded respectively on the screw mandrel 2 of arm-tie 3 and top board 1 outer end, Horizontal jack 4 is arranged between top board 3 and belt pulley 10, the tail end top of Horizontal jack 4 is pressed on top board 3, the top, working end of Horizontal jack 4 is pressed on the output shaft of motor 6, the output shaft concentric of Horizontal jack 4 and motor 6.
Many group through holes 11 are set on arm-tie 1 and top board 3, organize on the concentric circles that through hole is arranged on arm-tie 1 and top board 3 different-diameters more.
