Description

Technical Field

[0001] The utility model relates to the technical field of reducer gears, and more specifically to a noise-reducing gear for a reducer. Background Technique

[0002] A reducer is a power transmission mechanism, whose function is to convert the high speed and low torque of a motor or engine into low speed and high torque output to meet the working needs of various mechanical equipment. It is widely used in various mechanical transmission systems, such as conveying equipment, lifting equipment, vehicle drive, etc. The reducer transmits power through the meshing of gears and achieves the purpose of speed reduction through the combination of multiple gear sets. Therefore, the quality structure of the reducer gears plays an important role in the reducer.

[0003] For example, a reducer gear with the publication number of CN219549535U in the prior art includes a support sleeve and a plurality of fan-shaped grooves equidistantly arranged on the outer peripheral surface of the middle end of the support sleeve. Fan-shaped blocks are movably arranged on the fan-shaped grooves, and a connecting mechanism and a limiting mechanism are arranged between the support sleeve and the fan-shaped blocks; while the overall disassembly and assembly are flexible and simple, the fixing stability is high.

[0004] However, the above prior art still has the following problems when in use: The gears are usually sleeved on the power rod. After long-term use, the stability of the gears will be reduced due to wear, resulting in noise generated by the deviation when the gears are meshed with each other. Based on this, the utility model provides a noise-reducing gear for a reducer with high stability, which plays a role in reducing noise generation. Content of the Utility Model

[0005] In order to overcome the above defects of the prior art, the utility model provides a noise-reducing gear for a reducer, which supports the reducer gear through two semi-circular support plates, thereby improving the stability of the reducer gear, avoiding noise generated by the deviation of the reducer gear, and at the same time, using the sound-absorbing cotton on the inner wall of the semi-circular support plate to absorb noise, thereby reducing the spread of noise, so as to solve the problems appearing in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A noise-reducing gear for a speed reducer, including a speed reducer gear. Ring-shaped installation grooves are provided at both the front and rear ends of the speed reducer gear. Support components are provided in both ring-shaped installation grooves. Both support components include two semi-circular support plates that are detachably fixed. The two semi-circular support plates are both arranged in the ring-shaped installation grooves. A fixing collar connected to the speed reducer gear is sleeved on the two semi-circular support plates. The fixing collar is used to conveniently fix the two semi-circular support plates, thereby facilitating the disassembly of the semi-circular support plates. The fixing collar is arranged on the outer walls of the two semi-circular support plates. One end of each semi-circular support plate is fixedly provided with a semi-circular limiting plate. Ring-shaped limiting grooves are provided on the inner walls of both ring-shaped installation grooves. The two semi-circular limiting plates are both arranged in the ring-shaped limiting grooves. By rotating the semi-circular limiting plates in the ring-shaped limiting grooves, the stability between the semi-circular support plates and the speed reducer gear can be improved. Sound-absorbing cotton is fixedly adhered to the inner walls of the two semi-circular support plates. The two sound-absorbing cottons are in contact with each other. The sound-absorbing cotton can be used to absorb noise, so the noise can be reduced.

[0007] In a preferred embodiment, a limiting ring is fixedly provided on the side of the fixing collar close to the speed reducer gear. Semi-circular limiting grooves are provided on the outer walls of the two semi-circular support plates. The limiting ring is arranged in the two semi-circular limiting grooves. By matching the limiting ring with the semi-circular limiting grooves, the stability between the fixing collar and the speed reducer gear can be improved.

[0008] In a preferred embodiment, a plurality of fixing holes are provided on both fixing collars. The plurality of fixing holes are evenly distributed on the fixing collars and are used to firmly fix the fixing collars and the speed reducer gear together.

[0009] In a preferred embodiment, two mounting ring plates are provided at the ends of the two semi-circular support plates away from the speed reducer gear. The two mounting ring plates are rotatably connected to connect the two semi-circular support plates to the speed reducer housing.

[0010] In a preferred embodiment, one of the mounting ring plates is detachably fixed to one end of the two semi-circular support plates, and a plurality of mounting holes are provided on the other mounting ring plate for connecting the mounting ring plate to the speed reducer housing for use.

[0011] In a preferred embodiment, receiving grooves are provided on the outer walls on both sides of the two semi-circular support plates.

The fixing collar 5 is arranged on the outer walls of the two semi-circular support plates 4. Receiving grooves 14 are provided on the outer walls on both sides of the two semi-circular support plates 4. The two receiving grooves 14 on the two semi-circular support plates 4 correspond to each other one by one, and are used for receiving and fixing the bolts for the two semi-circular support plates 4;

[0023] One end of each semi-circular support plate 4 is fixedly provided with a semi-circular limiting plate 6. Ring-shaped limiting grooves 7 are provided on the inner walls of the two ring-shaped mounting grooves 2. The two semi-circular limiting plates 6 are both arranged in the ring-shaped limiting grooves 7. Sound-absorbing cotton 8 is fixedly adhered to the inner walls of the two semi-circular support plates 4. The two sound-absorbing cotton 8 are in contact with each other. The sound-absorbing cotton 8 can absorb noise, so the noise can be reduced;

[0024] Moreover, a limiting ring 9 is fixedly provided on the side of the fixing collar 5 close to the speed reducer gear 1. Semi-circular limiting grooves 10 are provided on the outer walls of the two semi-circular support plates 4. The limiting ring 9 is arranged in the two semi-circular limiting grooves 10. By matching the limiting ring 9 with the semi-circular limiting grooves 10, the stability between the fixing collar 5 and the speed reducer gear 1 can be improved in this way. A plurality of fixing holes 11 are provided on both of the two fixing collars 5. The plurality of fixing holes 11 are evenly distributed on the fixing collar 5 and are used for firmly fixing the fixing collar 5 and the speed reducer gear 1 together;

[0025] Furthermore, two mounting ring plates 12 are provided at the ends of the two semi-circular support plates 4 far from the speed reducer gear 1.
