Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a split-type speed reducer. Background Technology

[0002] A split-type reducer is a transmission device in which the motor and reducer are designed as independent modules. The two are connected by a coupling (such as a flexible coupling or a gear coupling) or a flange to transmit power. Its core feature is modular design, which allows the motor and reducer to be installed, maintained and replaced separately. It is suitable for scenarios with high requirements for flexibility and ease of maintenance.

[0003] Split-type reducers achieve speed reduction and torque increase through gear transmission. Their core principle is the same as that of ordinary reducers. The motor transmits power to the input shaft of the reducer through a coupling. The input shaft drives the pinion to rotate, and the pinion meshes with the large gear to achieve speed reduction.

[0004] Traditional speed reducers typically adopt an integrated design of motor and speed reducer, which has many problems during use. The integrated structure lacks versatility, is difficult to adapt to different specifications of motors, has poor versatility, and is difficult to adapt to different working scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a split-type reducer, comprising a reducer body, a motor body, and a mounting assembly. The mounting assembly is located on one side of the reducer body, and the motor body is located inside the mounting assembly. A reduction shaft is rotatably connected to the outer surface of the reducer body. A hexagonal plug is fixedly connected to the end of the reduction shaft away from the reducer body. An output shaft is fixedly connected to the output end of the motor body, and a hexagonal socket is provided at the end of the output shaft away from the motor body to facilitate the insertion of the hexagonal plug.

[0021] Please see Figures 1-5 The present invention provides the following two preferred embodiments:

[0022] Example 1: A split-type speed reducer includes a speed reducer body 1, a motor body 2, and a mounting assembly 3.

Reinforcing ribs 32 are fixedly connected to the outer side wall of the support plate 34. A lower arc plate 33 is fixedly connected to the side of the support plate 34 away from the base plate 31. A U-shaped connector is fixedly connected to the upper surface of the lower arc plate 33. A connecting shaft 314 is fixedly connected inside the U-shaped connector.

[0024] A connecting sleeve 313 is rotatably connected to the outer wall of the connecting shaft 314. An upper arc plate 310 is fixedly connected to the upper surface of the connecting sleeve 313. The upper arc plate 310 is rotatably connected to the connecting shaft 314 through the connecting sleeve 313 and can be flipped open and closed. An upper connecting plate 39 is fixedly connected to the outer surface of the upper arc plate 310. A screw 37 is threadedly connected to the upper connecting plate 39. A knob 38 is fixedly connected to the end of the screw 37 away from the upper connecting plate 39. The screw 37 and the knob 38 achieve quick locking of the upper arc plate 310 and the lower arc plate 33 through the threaded groove 36.

[0025] In use, first rotate the knob 38 to drive the screw 37 to rotate and disengage it from the threaded groove 36, that is, rotate it within the connecting sleeve 313 via the connecting shaft 314. This flips the upper arc plate 310. Then, place the motor body 2 on the lower arc plate 33, insert the hexagonal plug 5 into the hexagonal socket 7, and complete the connection between the reducer body 1 and the motor body 2. After flipping the upper arc plate 310 again, screw the screw 37 into the threaded groove 36 and close the upper arc plate 310 to complete the initial fixation of the motor body 2 and the mounting assembly 3. Then, rotate the turntable 311 to drive the adjusting rod 312 to rotate, pushing the arc-shaped connecting plate 315 and the arc-shaped fixing plate 317 to press the motor body 2, which facilitates the fixation of motor bodies 2 of different specifications.

[0026] Example 2: A protrusion is fixedly connected to the outer surface of the knob 38, and a lower connecting plate 35 is fixedly connected to the upper surface of the lower arc plate 33.

An arc-shaped fixing plate 317 is detachably installed on the outer wall of the arc-shaped connecting plate 315. The adjustment rod 312 and the turntable 311 push the arc-shaped fixing plate 317 to press against the motor body 2, which is suitable for motors of different specifications.

[0028] The upper surface of the arc-shaped fixing plate 317 is provided with an arc-shaped mounting groove 318 that is compatible with the arc-shaped connecting plate 315. The outer side wall of the arc-shaped fixing plate 317 is provided with a through hole, and a fixing rod 319 is inserted into the through hole. The through hole is connected to the arc-shaped mounting groove 318. The outer side wall of the arc-shaped connecting plate 315 is provided with a fixing screw hole 316.

[0029] When using the motor body 2, which requires a larger power motor, the operator loosens the fixing rod 319 to disengage it from the fixing screw hole 316. Then, the arc-shaped connecting plate 315 is pulled out from the arc-shaped mounting groove 318, and the original arc-shaped fixing plate 317 is removed. The widened arc-shaped fixing plate 317 is then inserted into the arc-shaped connecting plate 315 through the arc-shaped mounting groove 318. Finally, the fixing rod 319 is tightened to complete the replacement and re-tighten the motor body 2, making it compatible with motors of different power.
