Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer with a locking device. Background Art

[0002] The full name of the reducer is the reduction motor, which is a combination of a motor and a gearbox. It is also called a motor-reducer integrated machine. The main transmission structure of the reducer is assembled from a transmission motor (also called a motor) and a gearbox. The reducer needs to be installed on the main shaft of the motor when in use. In order to facilitate the connection of the motor main shaft, a coupling will be installed inside the reducer. During installation, the motor main shaft can be aligned with the coupling and inserted. After insertion, the motor is rotated so that the hole on the motor is aligned with the thread groove on the reducer. After alignment, the bolts are passed through the motor and the reducer can be fixed. However, since the motor is heavy, it is time-consuming and laborious to align the hole on the motor with the thread groove on the reducer. In addition, since the thread groove is directly opened on the reducer, it is not easy to replace the thread groove when it is slipped. There are certain shortcomings. For this reason, we propose a reducer with a locking device. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art or related technologies.

[0004] To this end, the technical solution adopted by the present invention is: a reducer with a locking device, including a body, a convex ring, a locking ring, a bolt and a gasket, a mounting seat for installing the main shaft is arranged on the right side of the body, the convex ring is arranged on the outside of the mounting seat, the locking ring includes a first locking plate inserted through the outside of the convex ring, a second locking plate abutting the rear side of the first locking plate, a fastening knob threadedly connected to the first locking plate, a fastener arranged on the first locking plate and a threaded groove opened on the right side of the first locking plate, the bolt is threadedly connected to the locking ring, and the gasket is inserted on the bolt.

[0005] Preferably, an output shaft is arranged at the front end of the machine body, and a coupling for connecting to the main shaft is arranged inside the mounting seat on the machine body.

[0006] Preferably, the convex ring is an annular structure.

[0007] Preferably, the first locking plate and the second locking plate have the same structure, both the first locking plate and the second locking plate are provided with mounting holes, and both the first locking plate and the second locking plate are provided with grooves on their inner sides.

[0008] Preferably, the fastening knob is a T-shaped stud.

[0009] Preferably, the fastener consists of a screw and a nut.

[0010] Preferably, the four gaskets correspond to the bolts one by one, and through holes are provided on the four gaskets.

[0011] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows: the utility model realizes the effect of quick assembly and disassembly without affecting the use of the reducer by arranging the convex ring and the locking ring, which saves time and effort, and the locking ring can be detached and replaced, avoiding the problem that it is difficult to replace when the thread groove is slipped. At the same time, by arranging the gasket, it is convenient to disassemble the bolt. When in use, the main shaft of the motor can be directly inserted into the body, and then the fastening knob of the locking ring can be loosened so that the fastening knob no longer abuts against the convex ring, and then the locking ring can be rotated so that the thread groove on the locking ring is aligned with the motor. The mounting holes on the motor can be aligned, and the bolts can be passed through the mounting holes on the motor and connected to the thread grooves. Finally, the tightening knob is tightened to achieve the locking effect. Compared with the traditional method of aligning the thread grooves by rotating the motor, the utility model saves more effort through the locking device, and the nut of the rotatable fastener can be disengaged from the screw. After disengagement, the first locking plate and the second locking plate can be directly separated, and the lock ring can be disassembled and replaced, avoiding the problem of difficulty in replacement when the thread grooves are slipped. At the same time, the bolts can be inserted with gaskets when fixing, and the gaskets can be used to drive the bolts out of the motor during disassembly, so that the bolts can be quickly disassembled.
