[0002] With the development of industrial automation and mechanization, air compressor is widely used in various industrial production processes as an important equipment, such as production line, pneumatic tool, chemical device and other fields. The main function of air compressor is to convert electrical energy into gas compression energy, providing high pressure gas source. However, the stability and efficiency of the driving device and lubrication system of air compressor directly affect the performance and service life of the equipment during long-term operation.

[0003] At present, many air compressors on the market use traditional liquid lubrication system. Although liquid lubricant can effectively reduce the friction and wear between parts, it may face the following problems during use:

[0004] Leakage of liquid lubricant: in the liquid lubrication system, lubricating oil is easy to leak under high temperature and high pressure, causing environmental pollution and equipment pollution.

[0005] Replacement and maintenance of lubricant: liquid lubrication system needs to replace lubricating oil regularly, and needs to clean the deposits in the system after long time running, increasing the difficulty and cost of maintenance.

[0006] Uneven lubrication: the lubricant distribution of traditional lubrication system sometimes cannot reach every part uniformly, leading to serious wear of some parts, while other parts are lubricated too much, affecting the service life and operating efficiency of the equipment.

[0007] At present, dry lubrication assembly mostly uses simple lubrication device for lubrication, but these existing technologies often have problems such as unstable lubrication and insufficient generation of lubricating powder, which cannot achieve ideal lubrication effect. In view of this, the existing problems are researched and improved, and an air compressor drive device is provided to solve the existing problems, aiming to solve the problems and improve the practical value through the technology.

Figures 1-4 The air compressor driving device provided by some embodiments of the present application comprises a transmission cabin 100, a driving motor 200, a dry lubricating assembly 300, an output shaft 120, a speed reduction transmission shaft 130 and a transmission shaft 140 which are rotatably installed on the inner side of the transmission cabin 100, and an output gear disc 210 which is arranged at the output end of the driving motor 200 and is used for transmission connection with the bottom end of the transmission shaft 140.

The bottom end of the speed reduction transmission shaft 130 is fixedly connected with a rotating flow paddle 400. The dry lubricating assembly 300 comprises a rotating disc seat 310, a gear disc 320 and two ear plates 330 which are rotatably installed on the surface of the rotating disc seat 310. The two ear plates 330 are oppositely arranged and rotatably installed on the surface of the rotating disc seat 310. An elastic member 340 is fixedly installed on the surface of the rotating disc seat 310, and the two ends of the elastic member 340 are respectively abutted with the end portions of the two ear plates 330. The gear disc 320 is fixed on the surface of the rotating disc seat 310 and is in transmission connection with the surface of the output gear disc 210. The surface of the ear plate 330 is provided with a graphite arc plate 331.

[0037] The ear plate 330 and the graphite arc plate 331 are in the shape of arc plate, and the centers of the ear plate 330 and the graphite arc plate 331 are concentric with the center of the gear disc 320. The inner side of the transmission cabin 100 is provided with a friction end block which is in sliding abutment with the surface of the graphite arc plate 331.

[0038] The cyclone paddle 400 is an axial fan blade structure, and the cyclone paddle 400 is rotationally driven by the reduction transmission shaft 130.

[0039] The transmission cabin 100 is a sealed cabin structure, and the surface of the transmission cabin 100 is fixedly provided with a mechanical seal sleeved on the surface of the output shaft 120.

[0040] The output gear disc 210 is in transmission engagement with the end of the transmission shaft 140 and the surface of the gear disc 320, and the driving motor 200 is a reduction motor structure.

[0041] One end of the lug plate 330 is provided with a shaft pin fixed to the surface of the rotary disc seat 310, and the other end of the lug plate 330 is provided with an elastic member 340, which is one of a spring and an elastic metal sheet.

[0042] The air compressor driving device provided by the embodiment comprises a transmission cabin 100, a driving motor 200, a dry lubricating assembly 300, and a plurality of rotating parts. The core objective of the device is to efficiently and stably transmit the power of the driving motor 200 to each part through the reduction transmission shaft 130, the output shaft 120 and other transmission devices, and to realize efficient lubrication function through the dry lubricating assembly 300.

[0043] Transmission cabin 100: One of the core components of the device, mainly serving to protect and accommodate the transmission device. The outer surface of the transmission cabin 100 is provided with an access door 110 for facilitating daily inspection and maintenance. The transmission cabin internally accommodates various components of the power transmission system and the lubrication system, ensuring that the entire driving device operates in a closed and sealed environment, thereby avoiding gas leakage.

[0044] Driving motor 200: A motor providing a main power source, usually an electric reduction motor. The driving motor 200 is connected with the transmission shaft 140 through the output gear disc 210 at its output end, pushing the reduction transmission shaft 130 and the output shaft 120 to rotate. The selection of the driving motor 200 is determined according to the required output power and the working conditions of the air compressor.

[0045] Dry lubricating assembly 300: Including a rotary disc seat 310, a gear disc 320, a lug plate 330, an elastic member 340 and a graphite arc plate 331. The main function of the lubricating assembly is to drive the rotation of the gear disc 320 and the lug plate 330 through the rotation of the rotary disc seat 310, so that the graphite arc plate 331 contacts the friction end block inside the transmission cabin 100 to generate lubricating powder. The lubricating powder flows between the components, reducing wear and providing long-term dry lubrication.

[0046] The cyclone paddle 400 is installed at the bottom end of the reduction transmission shaft 130 to provide air flow cyclone. During operation, the cyclone paddle 400 can generate rotating air flow to enhance the distribution of lubricating powder and ensure uniform lubrication of the surfaces of various transmission components such as the output shaft 120, the reduction transmission shaft 130, and the output gear disc 210.

[0047] Working process:

[0048] When the drive motor 200 starts, the motor transmits power to the transmission shaft 140 through the output gear disc 210, further driving the reduction transmission shaft 130 and the output shaft 120 to rotate.

[0049] During transmission, the reduction transmission shaft 130 transmits power to the cyclone paddle 400 through the output shaft 120, causing it to generate cyclone air flow. The air flow rotates through the rotating disc seat 310 of the lubricating assembly, driving the rotation of the gear disc 320 and the ear plate 330, which in turn causes the graphite arc plate 331 to contact the friction end block inside the transmission cabin 100.

[0050] This friction generates lubricating powder, which is uniformly distributed to the surfaces of various transmission components through the air flow, avoiding the problem of liquid lubricating oil leakage, effectively reducing the wear between components, and improving the stability of the device.

[0051] Lubricating effect: Through the contact between the graphite arc plate 331 and the friction end block, the generated lubricating powder forms a lubricating film on the surface of the gear disc 320 and other transmission components, reducing the friction between parts, thereby reducing wear and heat generation, and ensuring long-term stable operation of the device.

[0052] Compact structure and sealing: all transmission and lubricating components are effectively encapsulated in the transmission cabin 100, preventing external environment from affecting the device. The sealed design of the transmission cabin 100 avoids gas leakage and lubricant contamination, ensuring the efficiency and reliability of the device during long-term operation.
