Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for a speed reducer. Background Art

[0002] A reducer is a standalone component consisting of a gear, worm, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission between a prime mover and a working machine. It matches speeds and transmits torque between the prime mover and the working machine or actuator, making it widely used in modern machinery. However, during operation, friction between the gears of the reducer generates significant heat. Furthermore, due to the high ambient temperature, heat dissipation is poor due to the proximity of the housing. This heat buildup can cause lubricants and seals to lose effectiveness temporarily, even affecting transmission accuracy and causing malfunctions, resulting in unsatisfactory performance.

[0003] Existing technology can ventilate and dissipate heat for reducers through vents and fans. However, existing vents are generally equipped with dust screens to intercept dust and prevent it from entering the reducer. When the dust screens are in use, dust accumulates on their surfaces, thereby affecting the ventilation effect of the vents. Therefore, those skilled in the art have provided a heat dissipation device for reducers to address the problems raised in the above background technology. Utility Model Content

[0007] As a further solution of the present invention: the front end of the connecting rod is provided with an insertion groove, and the rear end of the mounting rod is fixedly connected with an insertion block, wherein the insertion block is inserted into the insertion groove and connects the mounting rod and the connecting rod together.

[0008] As a further solution of the present invention: a plurality of ventilation holes are provided around the reducer body, wherein the ventilation holes can be used for ventilation and heat dissipation, and dustproof nets are fixedly installed on the ventilation holes, wherein the dustproof nets can be used to intercept dust and reduce dust from entering the reducer body.

[0009] As a further solution of the present invention: a circular groove is opened on the inner wall of the rear end of the reducer body, wherein the fan is located in the circular groove, and the rear end of the reducer body is fixedly connected to the outer frame, wherein the double-headed motor is fixedly installed in the outer frame.

[0010] As a further solution of the present invention: the front end of the base is fixedly connected to a second support frame, wherein the upper end of the second support frame is fixedly connected to the reducer body, and the rear end of the base is fixedly connected to the first support frame, wherein the first support frame is fixedly connected to the reducer body, and the second rotating shaft is rotatably connected to the first support frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. When heat dissipation is required, starting the double-headed motor can drive the first rotating shaft to rotate, and the first rotating shaft drives the fan to rotate.

Multiple vents can ventilate and dissipate heat for the reducer body.

[0013] 2. When it is necessary to clean the dust on the dustproof net, start the double-headed motor, and the mounting rod can drive the brush layer to rotate around the outer surface of the reducer body. The brush layer will contact the dustproof net during rotation and clean the dust on the dustproof net. Most of the cleaned dust will fall into the rectangular groove and adhere to the electrostatic dust pad, which can collect the dust and reduce the possibility of dust continuing to float.

[0014] 3. Pull the mounting rod forward to pull the insert block out of the insertion slot. This allows the mounting rod to be removed from the connecting rod, making it easier to replace the mounting rod or clean the brush layer on the mounting rod. BRIEF DESCRIPTION OF THE DRAWINGS
