Special puller of SA series speed reducer

Technical Field

The utility model relates to a draw the horse, more specifically say, especially relate to a special horse that draws of SA series speed reducer.

Background

The SA series speed reducer (hollow shaft series) is widely applied to the storage, logistics and tobacco industries due to the characteristics of compact structure and wide power, torque and speed ranges. In the use process, the disassembly and assembly maintenance of the speed reducer is inevitably involved. At present, the method for disassembling the speed reducer from the transmission shaft adopts a puller or the puller is matched with auxiliary pieces with different shapes, and the auxiliary pieces are fixed on the end surface of the inner side of the speed reducer to pull out the speed reducer. In this way, a proper stress position needs to be found on the side end face of the reducer so that the reducer is stressed uniformly when the puller works. However, in the actual working process, it is difficult to find a proper stress position on the back of the speed reducer, so that each pulling claw can be uniformly stressed when the puller works, and the pulling claws slip and loosen in the working process. Therefore, when the speed reducer is disassembled, various pulling horses are required to try to disassemble, or a series of auxiliary tools are arranged to be fixed on the end face of the inner side of the speed reducer to provide a position for uniform stress of the pulling claw, so that the defects of high disassembling difficulty, large quantity of spare tools, high tool maintenance cost and the like exist.

In the puller special for the SA series speed reducer, the adjusting seat consists of a seat body in threaded connection with the adjusting thread part and a plurality of cantilevers uniformly distributed at intervals along the circumferential direction of the seat body; the adjusting long hole is arranged in the middle of the cantilever along the length direction of the cantilever.

In the puller special for the SA series speed reducer, the two sides of each adjusting long hole along the length direction are respectively provided with the reinforcing ribs, and the reinforcing ribs are arranged on the end surfaces of the base body and the cantilever close to the hydraulic starting rod.

In the puller specially used for the SA series speed reducer, the guide sleeve in threaded connection with the adjusting thread part is integrally formed on the upper end surface and the lower end surface of the base body.

In the puller special for the SA series speed reducer, the positioning screw is composed of a nut, a limit post connected with the nut, and a screw rod part arranged at the free end of the limit post; the outer diameter of the screw rod part is smaller than that of the limiting column.

The utility model adopts the above structure after, through setting up the regulation seat and being connected with regulation screw thread portion, through the screw hole threaded connection that the outer end of set screw is direct to be covered with the speed reducer, adopt the direct mode of pulling out to dismantle the speed reducer. Because the threaded holes on the outer end cover are uniformly distributed along the circumferential direction of the transmission shaft, the stress of each stress point is uniformly protected when the puller works. Simultaneously, adjust the slot hole through setting up, make the utility model discloses a draw the horse, can adapt to the dismantlement of whole SA series speed reducer for the dismantlement of SA series speed reducer is maintained and is become very convenient and fast. Not only saves a large amount of tools, but also improves the working efficiency.
