Between the original machine and the work machine or actuator, match speed and transmit torque, widely used in modern machinery. The performance and service life of speed reducer are closely related to the cleanliness of its internal gear. In the production and assembly process of gear, the gear surface often adheres cutting fluid, oil stains, metal debris and other impurities, if these impurities are not removed in time, will affect the meshing precision of gear, increase wear, even lead to speed reducer failure. Therefore, the cleaning of gear is the key link in the production process of speed reducer.

[0003] In the prior art, gear cleaning equipment is mainly divided into two categories: one is traditional soaking cleaning, and the other is spray cleaning. Soaking cleaning is to immerse the gear in cleaning liquid, and remove the surface stains by ultrasonic wave or mechanical stirring. This method can clean the complex surface of gear, but the soaking time is long, the cleaning efficiency is low, and it is difficult to meet the demand of mass production. Spray cleaning is to spray cleaning liquid to the gear surface by high-pressure nozzle, and use the impact force of liquid to remove stains. This method has high cleaning efficiency, but the cleaning effect of interdental part is limited, especially for gear with complex tooth shape or small size, the cleaning liquid is difficult to fully penetrate into the interdental area.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 The gear cleaning device for the reducer shown includes a cleaning tank 1, which is a semi-enclosed box. Figure 1 The structure shown is a schematic diagram of the top cover opening upwards. Figure 1 Based on this, the left side of the cleaning tank 1 is the inlet, the right side is the outlet, and the bottom is the drain end. The overall internal structure of the tank is high at both ends and low in the middle, which facilitates the rapid collection of cleaning fluid at the bottom. The cleaning tank 1 is equipped with a transmission mechanism 2 and a cleaning mechanism 3. The transmission mechanism 2 includes a first horizontal section 2a, an inclined section 2b, and a second horizontal section 2c. The transmission belt used in the transmission mechanism 2 has a hollow structure to facilitate the discharge of cleaning fluid. For details, please refer to [reference needed]. Figure 1 and Figure 2 The first horizontal section 2a is connected to the bottom end of the inclined section 2b, and the second horizontal section 2c is connected to the upper end of the inclined section 2b. The first horizontal section 2a is close to the inlet of the cleaning tank 1, and the second horizontal section 2c is close to the outlet of the cleaning tank 1. The gear enters from the first horizontal section 2a, passes through the inclined section 2b, and exits from the second horizontal section 2c. In a preferred embodiment, the first horizontal section 2a extends to the outside of the inlet of the cleaning tank 1 to facilitate feeding.

[0023] Referring to Figure 1 , Figure 2 and Figure 3 , the cleaning mechanism 3 comprises a first spray head 3a, a rolling brush 3b and a second spray head 3c arranged in sequence, wherein the first spray head 3a and the rolling brush 3b are located at the top of the first horizontal section 2a, and the second spray head 3c is arranged at the top of the inclined section 2b. In a preferred embodiment, the rolling brush 3b is provided with two brushes, and the bristles of the two brushes are arranged in a staggered manner. The rolling brush 3b is composed of a hollow reel and a soft brush, which is driven by a motor. The two rolling brushes 3b are connected by a belt pulley transmission, and the bristles of the two rolling brushes are arranged in a staggered manner, which can more comprehensively cover the gear surface and the tooth gap, and ensure that there is no cleaning dead angle. In addition, the first spray head 3a adopts a single-pipe multi-nozzle structure, and the second spray head 3c adopts a multi-pipe multi-nozzle structure. The second spray head 3c covers the entire area on the upper side of the inclined section 2b, and the orientations of the multiple nozzles are different, which can achieve comprehensive coverage of the gear surface and the gear slot. The combination of the inclined section 2b and the second spray head 3c enables the second spray head 3c to have a better flushing angle. The cleaning liquid sprayed out has a relative movement trend with the gear, and the cleaning effect is better. Furthermore, the cleaning liquid can quickly collect at the bottom end and separate from the gear surface under the inclined angle, which facilitates subsequent air drying.

[0024] The cleaning device also comprises a cleaning liquid supply system, which is composed of a liquid source end and a circulating pump 4. The suction end of the circulating pump 4 is connected with the liquid source end and the drain end of the cleaning tank 1, and the output end is connected with the first spray head 3a and the second spray head 3c. Furthermore, it also comprises a filter part 6, which is composed of a primary filter unit 6a and a secondary filter unit 6b. The primary filter unit 6a is arranged in the cleaning tank 1 and located at the bottom of the transmission mechanism 2. The secondary filter unit 6b is arranged at the front end of the suction end of the circulating pump 4. By arranging the cleaning liquid supply system and the filter part 6, the waste liquid can be recycled and filtered for reuse, reducing the waste of cleaning liquid.

[0025] Referring to Figure 1 and Figure 4 , in a specific embodiment, the gear cleaning device of the speed reducer further comprises an air drying mechanism 5, which is arranged inside the cleaning tank 1 and located at the upper side of the second horizontal section 2c. The air drying mechanism 5 is connected with an air compressor, which provides high-pressure airflow to quickly dry the cleaned gear. The air outlet 5a of the air drying mechanism 5 is arranged obliquely, which can better cover the gear surface and ensure uniform drying.

[0026] In addition, the inlet and outlet of the cleaning tank 1 are respectively provided with protective curtains 7, which can effectively block the splashing of the liquid during cleaning, keep the working environment clean, and avoid waste of cleaning liquid.
