Description

Technical Field

[0001] This utility model belongs to the technical field of automated production line equipment, and in particular relates to a self-lubricating silent drive module. Background Technology

[0002] In fields such as automated production lines and robotics, self-lubricating silent drive modules can improve equipment operating efficiency and reliability, reduce equipment maintenance costs and noise pollution, and provide workers with a better working environment.

[0003] However, in existing drive module technology, lubrication and noise reduction are two key issues. The lubrication system of traditional drive modules is often relatively simple, usually using manual lubrication on a regular basis. This method not only requires frequent manual maintenance, but also makes it difficult to ensure the uniform distribution of lubricating oil. Due to insufficient or excessive lubrication, the friction coefficient between moving parts is high, which can easily generate greater noise and heat accumulation, thereby affecting the service life and operating efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating silent drive module, which effectively solves the problem that the lubrication system of traditional drive modules is difficult to ensure the uniform distribution of lubricating oil due to the use of periodic manual oiling.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a self-lubricating silent drive module, including a frame and a lubrication component. A servo motor is provided at the front end of the frame, and two guide rails are symmetrically arranged on the top surface of the frame.

Detailed Implementation

[0025] Example 1: A self-lubricating silent drive module, such as Figure 1 As shown, the device includes a frame 1 and a lubrication assembly. A servo motor 2 is located at the front end of the frame 1, and two guide rails 3 are symmetrically arranged on the top surface of the frame 1. A threaded rod 4 is rotatably connected inside the frame 1, and the front end of the threaded rod 4 is connected to the output shaft of the servo motor 2. The servo motor 2 can drive the threaded rod 4 to rotate.

[0026] like Figure 1 and Figure 2 As shown, the lubrication assembly includes a sliding unit 9, two oil reservoirs 5, and two sleeves 6. The sliding unit 9 spans the two guide rails 3 and is slidably connected to the guide rails 3. The middle part of the sliding unit 9 extends downward to form a threaded rod connection part 7. The threaded rod 4 passes through the threaded rod connection part 7 and is threadedly connected to the threaded rod connection part 7. The sliding unit 9 can reciprocate by rotating the threaded rod 4 in both directions.

[0027] like Figure 2 and Figure 3 As shown, two oil reservoirs 5 are respectively located at the front and rear ends of the sliding unit 9. Each oil reservoir 5 has an oil inlet pipe 8, through which lubricating oil can be added. Molybdenum disulfide is also added to the lubricating oil. A placement groove is provided on the sliding unit 9 at a position corresponding to the guide rail 3. Several ball bearings 10 are placed in the placement groove, and the ball bearings 10 contact the guide rail 3. Multiple oil outlets 11 are provided on the oil reservoir 5 at positions corresponding to the placement groove. In this embodiment, the ball bearings 10 are arranged in two layers within the placement groove, and each layer of ball bearings 10 is arranged in a straight line along the axis of the guide rail 3.

[0028] When the sliding unit 9 begins to move, lubricating oil enters the corresponding placement groove through the oil outlet 11, then contacts the surface of the ball 10, forming an oil film on the surface of the ball 10. As the ball 10 moves, the oil film is evenly distributed across the entire contact surface of the guide rail 3. This reduces direct metal-to-metal contact between the sliding unit 9 and the guide rail 3, lowers the coefficient of friction, slows wear, and also reduces heat and noise generated by friction. Simultaneously, the smooth surface reduces the resistance of the lubricating oil, making the lubrication process smoother and further reducing noise. Furthermore, the molybdenum disulfide additive in the lubricating oil forms a protective film on the metal surface, further reducing direct metal-to-metal contact and the coefficient of friction, thereby reducing noise generated by friction.

[0029] like Figure 3 and Figure 4 As shown, two sleeves 6 are symmetrically arranged at the front and rear ends of the threaded rod connection part 7. The sleeves 6 are connected to the oil storage tank 5 through the oil supply pipe 20. Several oil outlet holes 12 are evenly arranged on the inner wall of the sleeves 6. The threaded rod 4 passes through the sleeves 6. A sponge 13 is provided inside the sleeves 6, and the sponge 13 is connected to the threaded rod 4.

[0030] like Figure 5 and Figure 6 As shown, in this embodiment, the sponge 13 is connected to the sleeve 6 via the mounting bracket 14. A collar 15 is fixedly installed on the free end of the sleeve 6. The collar 15 has four evenly spaced fixing grooves 16. A limit block 18 is connected to the fixing groove 16 via a spring 17. The reaction force of the spring 17 allows the limit block 18 to reset. The free end of the limit block 18 is arc-shaped. Figure 7 As shown, the two ends of the sponge 13 are connected in a cylindrical shape by snap-fit. The mounting bracket 14 is engaged with the cylindrical sponge 13. The mounting bracket 14 is provided with a slot 19 at a position corresponding to the fixing groove 16. The slot 19 is engaged with the limiting block 18.

[0031] As the sliding unit 9 moves, lubricating oil enters the sleeve 6 through the oil supply pipe 20. The lubricating oil inside the sleeve 6 comes into contact with the sponge 13 through the oil outlet. The sponge 13 absorbs the lubricating oil and then wipes and lubricates the surface of the threaded rod 4, thereby achieving automatic lubrication, reducing manual maintenance, and reducing noise caused by friction.

[0032] After a period of use, the sponge 13 will wear down as it wipes the surface of the threaded rod 4, requiring replacement. To remove the sponge 13, pull the mounting bracket 14 outwards. The slot 19 will then compress the arc-shaped end of the limiting block 18, causing it to retract and disengage from the mounting bracket 14 and the collar 15. The movement of the mounting bracket 14 will move the sponge 13 out of the sleeve 6. Pulling the sponge 13 further will disengage it from the mounting bracket 14. The sponge 13 can then be removed from the threaded rod 4 by opening the clips. When installing a new sponge, the sponge 13 is fitted onto the surface of the threaded rod 4 and the two ends of the sponge 13 are snapped together to form a cylindrical shape. Then, the sponge 13 is inserted into the mounting bracket 14 for fixation. Then, the mounting bracket 14 and the sponge 13 are inserted together into the sleeve 6. The reaction force of the spring 17 causes the limiting block 18 to engage with the slot 19, thereby fixing the mounting bracket 14 and the sponge 13.

[0033] In this embodiment, both the oil outlet 11 and the oil supply pipe 20 are equipped with electrically controlled valves. The supply of lubricating oil can be controlled by the electrically controlled valves to ensure that the ball bearing 10 and the threaded rod 4 are always in a state of proper lubrication, and to prevent poor lubrication caused by too much or too little lubricating oil.

[0034] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
