[0002] Dry oil is also called lubricating grease, and it is a kind of semi-solid lubricant, which is composed of base oil, thickening agent and additive. The base oil provides lubricating performance, the thickening agent makes the lubricating grease have certain consistency and shape, and the additive is used to improve the oxidation resistance, wear resistance and many other properties of the lubricating grease. The lubricating grease has good adhesion, can form an oil film on the friction surface, reduces wear and prevents corrosion, and is often used in some occasions where lubricating oil is not suitable, such as open gears, rolling bearings, etc.;

[0003] At present, dry oil supplement is generally divided into two supplement modes of manual oil supplement and centralized lubrication system oil supplement. Large equipment or complex equipment with multiple lubrication points generally has a centralized lubrication system.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1-7 The embodiment provides a technical scheme: a full-digital centralized dry oil lubrication system oil supplementing mechanism, which comprises an oil supply shell 1 and a spiral oil conveying assembly 3.

[0027] The oil supply shell 1 is fixedly connected with the top cover 2 at the top, the outer part of the oil supply shell 1 is provided with the control switch 8, the input end of the control switch 8 is electrically connected with the external power supply, the lower end of the oil supply shell 1 is provided with the oil outlet 5, the outer arc surface left upper side of the oil supply shell 1 is provided with the oil inlet pipe 6, the upper end of the oil inlet pipe 6 is externally connected with the external oil supply equipment, the outer arc surface lower side of the oil supply shell 1 is fixedly connected with the mounting frame 4, the lower surface of the mounting frame 4 is provided with the evenly distributed threaded mounting holes, when the oil supplementing mechanism needs to be used, the mounting frame 4 can be installed to the specified work station through the threaded mounting holes and the external bolts, the external oil supply equipment can be controlled, and the lubricating grease can be slowly discharged into the oil supply shell 1;

[0028] The screw oil conveying assembly 3 comprises a rotating rod 31, a first rotating disc 32, an outer rotating disc 33, a driving gear 34, a tooth ring 36, a lower limit ring 37, a screw blade 38 and a scraping blade 39. The rotating rod 31 is rotationally connected to the middle part of the lower side of the top cover 2. The outer arc surface of the rotating rod 31 is fixedly connected with the driving gear 34. The lower end of the driving gear 34 is fixedly connected with the first rotating disc 32. The inner arc surface of the upper side of the oil supply shell 1 is fixedly connected with the lower limit ring 37. The inner arc surface of the upper side of the oil supply shell 1 is fixedly connected with the tooth ring 36. The tooth ring 36 and the lower limit ring 37 are rotationally connected with the outer rotating disc 33. The inner arc surface of the outer rotating disc 33 is rotationally connected with the outer arc surface of the first rotating disc 32. The outer arc surface of the rotating rod 31 is fixedly connected with the screw blade 38. The lower surface of the outer rotating disc 33 is fixedly connected with the uniformly distributed scraping blades 39. The outer shape of the screw blade 38 is gradually decreasing and matched with the oil supply shell 1. The area of the lower end of the screw blade 38 is smaller than that of the upper side, so that the greater the downward conveying of the lubricating grease, the greater the pressure. The scraping blades 39 are located between the oil supply shell 1 and the screw blade 38. The scraping strips of the scraping blades 39 are in real time in contact with the inner wall of the oil supply shell 1. The outer shape of the scraping blades 39 is matched with the inner shape of the oil supply shell 1. The screw oil conveying assembly 3 further comprises a driven gear 35. The upper surface of the outer rotating disc 33 is rotationally connected with the driven gears 35 through rotating shafts left and right symmetrically. The two driven gears 35 are meshingly connected with one driving gear 34. The two driven gears 35 are meshingly connected with one tooth ring 36. The upper end of the top cover 2 is fixedly connected with the motor 7. The output shaft of the motor 7 is fixedly connected with the upper end of the rotating rod 31. The input end of the motor 7 is electrically connected with the output end of the control switch 8. At this time, the control switch 8 can be adjusted and controlled. The motor 7 operates. The output shaft of the motor 7 rotates, thereby driving the rotating rod 31 to rotate, thereby driving the screw blade 38 to rotate, thereby driving the driving gear 34 to rotate, thereby driving the two driven gears 35 to rotate, thereby driving the outer rotating disc 33 to rotate. Because the diameter of the driven gear 35 is smaller than that of the driving gear 34, the rotating speed of the outer rotating disc 33 is smaller than that of the driving gear 34, so the rotating speed of the screw blade 38 is greater than that of the scraping blade 39. After the lubricating grease enters the oil supply shell 1, it will be conveyed by the screw blade 38. In the conveying process, the scraping blades 39 will scrape the lubricating grease adhered to the side wall of the oil supply shell 1, and finally sprayed from the oil outlet 5, ensuring the smoothness of the lubricating grease conveying. When this mechanism is applied to the multi-pipeline dry oil supply equipment room, the rotating speed of each motor 7 can be adjusted and controlled in turn, thereby adjusting and controlling the conveying speed of each pipeline, ensuring that each pipeline can enter the lubricating equipment at a specified supply rate.

[0029] The working principle of the full-digital centralized dry oil lubrication system oil supplement mechanism is as follows: when the oil supplement mechanism needs to be used, the installation frame 4 is installed on the specified station through the threaded mounting hole and the external bolt, the external oil supply equipment is controlled, the lubricating grease is slowly discharged into the oil supply shell 1, the control switch 8 is controlled at this time, the motor 7 is operated, the output shaft of the motor 7 rotates, and then drives the rotating rod 31 to rotate, and then drives the spiral blade 38 to rotate, and then drives the driving gear 34 to rotate, and then drives the two driven gears 35 to rotate, and then drives the external rotating disc 33 to rotate, because the diameter of the driven gear 35 is smaller than that of the driving gear 34, so the rotating speed of the external rotating disc 33 is smaller than that of the driving gear 34, so the rotating speed of the spiral blade 38 is greater than that of the scraper 39, after the lubricating grease enters the oil supply shell 1, the spiral conveying of the spiral blade 38 is received, in the conveying process, the scraper 39 scrapes the lubricating grease adhered to the side wall of the oil supply shell 1, and the lubricating grease conveying is smooth, and the mechanism is applied to the multi-pipeline dry oil supply equipment room, and then the rotating speed of each motor 7 is controlled, and then the conveying speed of each pipeline is controlled, and the pipelines can enter the lubricating equipment at a specified supply rate.

[0030] It is worth noting that the motor 7 disclosed in the above embodiment can be freely configured according to the actual application scene, and the motor 7 is recommended to be a planetary reduction motor of 42HC151-60U19PF10 type, and the control switch 8 is provided with a control button corresponding to the motor 7 and used for controlling the switch of the motor 7.

[0031] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation obtained by using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
