Abstract
The utility model provides a wheel puller for a motor belt pulley, which comprises a screw rod, a nut rod, pulling plates, a belt pulley and a motor shaft, wherein teeth are formed on the inner side of each pulling plate and engaged with the belt pulley, two pulling plates are symmetrically suspended over the belt pulley, two ends of the nut rod are mounted on the two symmetrically-arranged pulling plates in a penetrating manner, fixing clamps are symmetrically mounted on the two pulling plates, external threads of the screw rod are engaged with female threads of the nut rod, the belt pulley is mounted on the motor shaft, the motor shaft is mounted on a motor, and teeth are formed on the outer side of each pulling plate and have different sizes from the teeth on the inner side. The contact area between the pulling plates and the belt pulley is increased, so that the belt pulley is uniformly stressed and protected against damage, resulting in the reduction of production cost. The wheel puller has a smart structure and is suitable for dismounting a belt pulley with a small gap to a motor casing.
Description
Technical field
The utility model is the device of dismounting motor, particularly a kind of motor pulley pulley extractor.
Background technology
Existing belt pulley pulley extractor is three melons or two melon formula belt pulley pulley extractors, when pulling out motor pulley, the front end of three melons or two melons is suspended on the back transverse plane of belt pulley, contact area is little, stressed big, three melons or two melons and belt pulley contact position often occur and pulled out the problem of splitting, cause belt pulley to damage, increase the consumption of belt pulley, increase production cost.Existing belt pulley pulley extractor can not be installed on the less belt pulley in belt pulley and motor housing gap, and therefore, the existing belt pulley pulley extractor scope of application is little.
Summary of the invention
The purpose of this utility model is a kind of motor pulley pulley extractor of design, make it when the dismounting motor pulley, contact with the belt pulley large tracts of land, make the belt pulley stress equalization, the belt pulley contact position can not occur and be pulled out the problem of splitting, be applicable to dismounting belt pulley and the less belt pulley in motor housing gap yet.
The purpose of this utility model is achieved in that by leading screw, Nut pole, fixed card, pull out wheel plate, belt pulley, motor shaft forms, pull out the wheel plate inboard tooth that matches with belt pulley is arranged, pull out two symmetries of wheel plate and hang over belt pulley, the Nut pole two ends are through symmetrical two of installing and pull out on the wheel plate, fixed card rides over symmetrical two of installing and pulls out on the wheel plate, the external screw thread of leading screw and the box thread of Nut pole screw, belt pulley is installed on the motor shaft, motor shaft is installed on the motor, and pulling out the wheel plate outside has the tooth different with inside dimensions.
The beneficial effects of the utility model are: pull out wheel plate and the belt pulley contact area is big, make the belt pulley stress equalization, can not damage belt pulley, can save production cost, the utility model structure is small and exquisite, is applicable to dismounting belt pulley and the less belt pulley in motor housing gap.
Description of drawings
Accompanying drawing is the installation diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
Among the figure: the 1st, leading screw, the 2nd, Nut pole, the 3rd, fixed card, the 4th, pull out wheel plate, the 5th, belt pulley, the 6th, motor shaft, the 7th, motor.Be that the utility model is by leading screw 1, Nut pole 2, fixed card 3, pull out wheel plate 4, belt pulley 5, motor shaft 6, motor 7 is formed, pull out wheel plate 4 inboards the tooth that matches with belt pulley 5 is arranged, pull out 4 two symmetries of wheel plate and hang over belt pulley 5, Nut pole 2 two ends are through symmetrical two of installing and pull out on the wheel plate 4, fixed card 3 rides over symmetrical two of installing and pulls out on the wheel plate 4, the box thread of the external screw thread of leading screw 1 and Nut pole 2 screws, belt pulley 5 is installed on the motor shaft 6, motor shaft 6 is installed on the motor 7, pulling out wheel plate 4 outsides has the tooth different with inside dimensions, so that pull out the belt pulley of tearing different size open with pulling out wheel plate 4.
Rotating threaded shaft 1 when pulling out wheel makes belt pulley 5 produce the axial force that breaks away from motor shaft, thereby extracts belt pulley 5.
