Abstract
The utility model relates to a repair tools of motor, in particular to device is extracted to belt pulley, including the jackscrew pole, the jackscrew pole includes roof pressure end and application of force end, and device is extracted to belt pulley still includes the rim plate, and the rim plate has central threaded holes and and is used for installing the bolt mounting holes on the belt pulley through the bolt, and the jackscrew pole is installed in central screw hole. Use, the rim plate passes through the bolt and installs on the belt pulley, the jackscrew pole is installed in the central screw hole of rim plate, the jackscrew pole passes through threaded connection with the rim plate and forms a screw -nut mechanism, the roof pressure end top of jackscrew pole is on the motor shaft, application of force end through the acropetal lead screw makes the jackscrew pole rotate, the rim plate outwards removes, drive and extract with the fixed belt pulley together of rim plate, it is convenient to extract the device use, but one -man operation, do not exist because of the problem of belt pulley with the closely unable operation of motor end cover distance, wide application range, and can not damage the motor belt wheel, do not influence reusing of belt pulley.
Description
Technical field
The utility model relates to a kind of maintenance tool of motor, particularly a kind of belt pulley extracting apparatus.
Background technology
Doing on the equipment of power with motor, the particularly beam pumping unit of petroleum industry, often need change at the scene and keep in repair motor pulley, belt pulley and motor shaft adopt interference fit, usually need to be extracted by belt pulley by extracting apparatus at present in disassembly process.
As notification number be CN202922167U, the day for announcing is that the Chinese patent document on May 8th, 2013 discloses a kind of belt pulley extracting apparatus, comprise jackscrew bar and center of circle dish, jackscrew bar comprises top pressure side and force side, and jackscrew bar coils with the center of circle and is threaded, and center of circle dish is provided with claw.During use, claw is stuck on the wheel rim of belt pulley, by making jackscrew bar rotate to the force side of jackscrew bar, belt pulley is driven to extract by claw, but belt pulley plasticity is poor, intensity is not high, and flange thickness is generally at 10 ㎜, and the contact area of claw and belt pulley is less, easily causing wheel rim inside belt pulley damaged, reusing affecting belt pulley time serious.In addition, there is claw and can not enter the problem causing operation failure in part belt pulley and electric motor end cap close together.
Utility model content
The purpose of this utility model is to provide a kind of belt pulley extracting apparatus not damaging rim of pulley.
For achieving the above object, the technical scheme of the utility model belt pulley extracting apparatus is:
A kind of belt pulley extracting apparatus, comprise jackscrew bar, jackscrew bar comprises top pressure side and force side, and belt pulley extracting apparatus also comprises wheel disc, wheel disc has screwed hole of centre and for being installed bolt mounting holes over pulleys carried by bolt, jackscrew bar is arranged in screwed hole of centre.
Described force side comprises six square toes.
Described force side comprises the radial hole on jackscrew bar.
The beneficial effects of the utility model are: belt pulley extracting apparatus of the present utility model in use, wheel disc is installed over pulleys carried by bolt, jackscrew bar is arranged in the screwed hole of centre of wheel disc, jackscrew bar and wheel disc are threaded connection and form a kind of leading screw and nut mechanism, the top pressure side of jackscrew bar withstands on motor shaft, by making jackscrew bar rotate to the force side of jackscrew bar, wheel disc is movement outwards, the belt pulley be fixed together with wheel disc is driven to extract, this extracting apparatus is easy to use, can one man operation, there is not the problem because belt pulley and electric motor end cap distance closely cannot operate, applied widely, and can not motor pulley be damaged, do not affect reusing of belt pulley.
Accompanying drawing explanation
Fig. 1 is the disassembled form structural representation of the embodiment 1 of the utility model belt pulley extracting apparatus;
Fig. 2 is the structural representation of the jackscrew bar of the embodiment 2 of belt pulley extracting apparatus;
Fig. 3 is the structural representation of the jackscrew bar of the embodiment 3 of belt pulley extracting apparatus.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
The embodiment 1 of belt pulley extracting apparatus of the present utility model, as shown in Figure 1, comprise jackscrew bar 1 and wheel disc 2, jackscrew bar 1 comprises top pressure side 11 and force side, top pressure side 11 is the cone-shaped end of the centre bore for pushing up motor shaft, wheel disc 2 has screwed hole of centre 21 and for being installed four bolt mounting holes 22 on pulley 3 by bolt, and jackscrew bar 1 is threaded connection and is arranged in screwed hole of centre 21.In the present embodiment, the force side of jackscrew bar 1 comprises six square toes 12, to use wrench operated.
During use, first the anticreep cover plate outside motor shaft is removed, wheel disc is installed over pulleys carried, the conehead of jackscrew bar is made to aim at the centre bore of motor shaft, rotated six square toes of jackscrew bar force side by spanner, drive wheel disc to move to the outside of motor, belt pulley can be extracted from motor shaft.
The embodiment 2 of belt pulley extracting apparatus of the present utility model, as shown in Figure 2, with embodiment 1 difference is, the force side of jackscrew bar 1 ' comprises the radial hole 12 ' be opened on jackscrew bar 1 ', during use, inserted by crowbar in radial hole, force makes jackscrew bar rotate.
The embodiment 3 of belt pulley extracting apparatus of the present utility model, as shown in Figure 3, with embodiment 1 difference is, jackscrew bar 1 ' ' force side comprise bending bar 12 ' ', and during use, adopt jacket casing to be connected on bending bar, force makes jackscrew bar rotate.
In other embodiments, six square toes of the jackscrew bar force side in embodiment 1 can also replace with square head, also can replace with common interior hexagonal hole, as long as can play the effect being convenient to rotate jackscrew bar.
Belt pulley extracting apparatus of the present utility model is applicable to change the motor pulley on petroleum industry oil pumper, is also applied to the belt pulley of other workplace motor.
