[0002] In automation and control systems, an actuator is a device used to execute or implement control instructions. The actuator is responsible for converting the output signal of the control system into actual actions or operations, which may include mechanical movement, opening or closing of valves, control of electrical equipment, etc.
[0003] In order to increase the torque at the output end of the actuator, a common method is to install a planetary reducer on the actuator, so that it can have a specified maximum torque. In this process, the lubrication of the gears in the reducer is an important indicator to ensure normal operation. Wear between gears will lead to increased transmission energy consumption. Directly applying lubricant between gears for lubrication not only consumes faster, but also the impurities in the lubricant cannot be effectively removed, resulting in unsatisfactory lubrication effect.

DETAILED DESCRIPTION
[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Example
[0019] like Figure 1-4As shown, a 250N wear-resistant actuator proposed by the utility model includes a driving housing 1 and a transmission housing 2 equipped with a planetary reducer, the transmission housing 2 is fixed at the bottom of the driving housing 1, a driving motor 11 is installed in the driving housing 1, and the output end is located in the transmission housing 2, a power supply 12 is fixed in the driving housing 1, an output shaft 21 is rotatably connected to the bottom of the transmission housing 2, a lubrication box 3 is fixed to the outside of the transmission housing 2, a connecting pipe 4 is fixed between the lubrication box 3 and the top of the transmission housing 2, and a circulating pump 41 is installed on the connecting pipe 4, a return pipe 5 is fixed between the upper end of the lubrication box 3 and the transmission housing 2, and a sewage discharge component 6 is arranged in the lubrication box 3.
[0020] The sewage discharge assembly 6 includes a funnel 61 and a sewage discharge pipe 62. The funnel 61 is fixed in the lubrication box 3. The bottom opening of the sewage discharge pipe 62 is fixed to the upper end of the sewage discharge pipe 62. An overflow hole 63 is provided on the outer wall of the sewage discharge pipe 62. A filter screen 64 is fixed in the overflow hole 63. A rotating plate 65 is rotatably connected to the center position of the bottom of the lubrication box 3. A through hole 67 is provided at the center position of the rotating plate 65. A sealing plug 68 is inserted in the through hole 67. A baffle 66 is fixed to the periphery of the upper end of the rotating plate 65. The inner wall of the baffle 66 abuts against the outer wall of the sewage discharge pipe 62, and a sealing gasket is provided at the connection. The baffle 66 corresponds to the overflow hole 63 one by one. A pull-out plate 69 is installed at the bottom of the rotating plate 65. A connecting rod is fixed between the pull-out plate 69 and the sealing plug 68. The bottom of the sewage discharge pipe 62 is rotatably connected to the upper end of the rotating plate 65. Positioning scale lines are provided on the bottom of the lubrication box 3 and the outer side of the rotating plate 65.
[0021] In this embodiment, the entire device is first connected to an external power source, and the output shaft 21 can be rotated by rotating the output end of the drive motor 11 and the transmission of the gears in the transmission housing 2. In this process, the output of the circulating pump 41 can be used to enable the connecting pipe 4 to inject the lubricant in the lubrication box 3 into the transmission housing 2 to lubricate the gear transmission, and finally flow back into the lubrication box 3 to achieve the purpose of circulating lubrication. At this time, the refluxed lubricant will enter the drain pipe 62 through the funnel 61, and the impurity particles in the lubricant will be filtered by the filter screen 64 so that they are retained in the drain pipe 62. When cleaning is required, it is only necessary to pull out the sealing plug 68. In order to prevent the lubricant from flowing out completely after pulling it out, the rotation of the rotating plate 65 can be used to drive the baffle 66 to slide on the outside of the drain pipe 62 to cover the overflow hole 63. Therefore, when the sealing plug 68 is pulled out, only a small amount of lubricant in the drain pipe 62 flows out, and the operation is more convenient.

Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
