Description

Technical Field

[0001] The utility model relates to the field of split-type reducers, in particular to a split-type reducer. Background Art

[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, a gear, and a worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery.

[0003] For example, a split-type reducer disclosed in the utility model with authorization announcement number CN219655228U determines the amount of oil in the machine body by the position of the pointer, so that the hammer continuously collides with the metal sheet, thereby continuously emitting a warning sound to remind the operator that the amount of oil in the machine body is insufficient, so that the machine body can be replenished with oil in time. At present, most split-type reducers are divided into reducers and motors, and most of the motors are integrated structures and are not easy to disassemble. Therefore, when the internal structure of the motor is damaged, it is difficult to achieve rapid maintenance of its internal structure, which affects the normal operation of the entire split-type reducer and causes unnecessary trouble. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a split reducer, which can solve the problem that the existing split reducer judges the amount of oil in the body by the position of the pointer, so that the hammer continuously collides with the metal sheet, thereby continuously emitting a warning sound to remind the operator that the amount of oil in the body is insufficient, so that the body can be replenished with oil in time. At present, most split reducers are divided into reducers and motors, and most of the motors are integrated structures and are not easy to disassemble. Therefore, when the internal structure of the motor is damaged, it is difficult to achieve rapid maintenance of its internal structure, which affects the normal operation of the entire split reducer, and thus causes unnecessary troublesome technical problems.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a split reducer, comprising a reducer body, the output end of the reducer body is connected to a spline shaft, and a stop block is provided on the outer surface of one end of the spline shaft, a first shell is distributed on one side of the reducer body, and a second shell is distributed on one end of the first shell, a through hole is opened on the side wall of the first shell, and a stop groove is connected to one side of the through hole, a clamping block is provided on the side wall of one end of the first shell, an extension rod is provided on the top side wall of the first shell, and a reset spring is provided on the inner side of the top end of the extension rod, a locking block is provided on the other end of the reset spring, and a heat dissipation structure is provided in the inner cavity of the first shell.

[0006] As a preferred technical solution of the utility model, the heat dissipation structure includes a heat conducting plate and heat dissipation fins, the heat conducting plate is distributed on the inner side of the first shell, and the side wall of the heat conducting plate is provided with heat dissipation fins.

[0007] As a preferred technical solution of the present invention, a slot is provided on the side wall of the second shell, and one end of the slot is connected to a lock hole, and a groove is provided on the end side wall of the second shell.

[0008] As a preferred technical solution of the present utility model, a motor body is distributed inside the second shell, and a connecting sleeve is connected to one end of the motor body.

[0009] As a preferred technical solution of the present utility model, the locking block is slidably connected to the extension rod via the return spring, and the extension rods are equidistantly distributed on the side wall of the first shell.

[0010] As a preferred technical solution of the utility model, the heat dissipation fins are equidistantly distributed on the side wall of the heat conducting plate, and the heat conducting plate is symmetrically distributed along the vertical center line of the motor body.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. By using the combination of the shell, the extension rod, the reset spring and the lock block, the subsequent rapid assembly and disassembly between the shells can be facilitated, which is convenient and quick, and has higher practicality. When the extension rod is input into the inner side of another shell, the reverse force generated by the deformation of the reset spring will push the lock block longitudinally, thereby realizing the longitudinal movement of the lock block, and then one end of the lock block will be input into the inner side of the shell, realizing the rapid connection between the two shells, which is not only more flexible, but also more convenient;

[0013] 2. By using the heat conducting plate and the heat dissipation fins in combination, the purpose of heat dissipation can be better achieved in the future, thereby preventing the motor body from generating a high temperature when working, thereby affecting the normal service life of the motor body. The heat generated by the motor body when working will be absorbed by the heat conducting plate, and then dissipated through the multiple heat dissipation fins evenly distributed on the side wall of the heat conducting plate, thereby achieving the purpose of heat dissipation.
