Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-lubricating copper bushing technology, specifically a self-lubricating structure for a copper bushing of a power transmission wheel in a processor. Background Technology
[0002] The copper bushing of a transmission wheel in a processing machine is a multi-functional mechanical component, primarily used in equipment requiring simultaneous conductivity, wear resistance, and low friction. The core of a self-lubricating copper bushing lies in combining the high strength of a metal substrate with a solid lubricant. A typical method involves machining regularly arranged cavities on the surface of the copper bushing and embedding solid lubricating materials such as graphite or molybdenum disulfide. This design achieves long-term lubrication without additional lubrication, making it particularly suitable for high-temperature, high-load, or difficult-to-maintain environments.
[0003] Traditional self-lubricating copper bushings use holes on the bushing surface filled with solid lubricant. However, these holes are directly exposed, making the lubricant susceptible to contaminants such as impurities and dust from the external environment, accelerating lubricant failure. The exposed holes also cause lubricant to leak during dynamic friction, resulting in resource waste and shortened lubrication cycles. Therefore, a self-lubricating structure for the copper bushing of the transmission wheel in a processing machine is needed to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a self-lubricating structure for the copper bushing of the electric drive wheel in a processor, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to a self-lubricating structure for the copper bushing of a power transmission wheel in a processor, comprising:
[0006] Flange copper sleeve;
[0007] The anti-damage component includes a first countersunk hole, a filter plate, and a support plate. The first countersunk hole is formed on the flange copper sleeve and is evenly distributed. The filter plate is placed inside the first countersunk hole, and the support plate is placed at the end of the first countersunk hole near the outer side of the flange copper sleeve.
[0008] Furthermore, the damage prevention component also includes a groove and a support plate. The groove is formed at one end of the first countersunk hole near the outer side of the flange copper sleeve, and one end of the support plate is fixed to both ends of the support plate and inserted into the groove.
[0009] Furthermore, the first countersunk hole is filled with a solid lubricant and is located at one end of the support plate near the inner side of the flange copper sleeve.
[0010] Furthermore, the filter holes on the filter plate are concentrated in the middle of the filter plate, and the diameter of the outer ring filter holes is smaller than the inner diameter of the guide hole on the inner side of the first countersunk hole.
[0011] Furthermore, it also includes a pushing component, which includes an opening, a first movable plate, a spring, and a second movable plate. The opening is located in the middle of the support plate, and the first and second movable plates are movably connected to both sides of the support plate. The spring is fixed between the first and second movable plates and is movably connected in the opening.
[0012] Furthermore, the pushing assembly also includes an arc-shaped plate, a fixing post, a mounting hole, and a second countersunk hole. There are two arc-shaped plates, which wrap around the outer side of the middle section of the flange copper sleeve. The fixing post is fixed at both ends of the arc-shaped plate. The mounting hole is opened in the middle of the fixing post. The second countersunk hole is opened at both ends of the flange copper sleeve. The mounting hole and the second countersunk hole are fixed by screws.
[0013] Furthermore, the pushing assembly also includes a reinforcing rib, one end of which is fixed to the inner side of the arc-shaped plate, and the other end is attached to the outer side of the flange copper sleeve.
[0014] Furthermore, the support plate is in clearance fit with the outer end of the first countersunk hole, and the clearance is very small. The diameters of the first movable plate and the second movable plate are smaller than the inner diameter of the outer end of the first countersunk hole.
[0015] This utility model has the following beneficial effects:
[0016] This invention utilizes a damage prevention component to evenly open a first countersunk hole and a groove on the flange copper sleeve. The filter plate is placed into the first countersunk hole, and a fixing lubricant is filled in. Then, the support plate is placed into the first countersunk hole, causing the support plate to snap into the groove. Subsequently, the fixing lubricant is filled from the inside of the flange copper sleeve into the guide hole at the rear end of the first countersunk hole. Finally, the flange copper sleeve is placed over the electric drive wheel. This design forms a physical isolation layer, preventing external impurities from entering the first countersunk hole and avoiding contamination of the lubricant. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] Please see Figure 1-4 As shown, this utility model is a self-lubricating structure for the copper bushing of a power transmission wheel in a processor, comprising:
[0028] Flange copper sleeve 10, fitted onto the outside of the electric transmission wheel of the processor;
[0029] The anti-damage component includes a first countersunk hole 20, a filter plate 22, and a support plate 23. The first countersunk hole 20 is opened on the flange copper sleeve 10 and is evenly distributed. The filter plate 22 is placed inside the first countersunk hole 20, and the support plate 23 is placed at the end of the first countersunk hole 20 near the outside of the flange copper sleeve 10.
[0030] The damage prevention component also includes a groove 21 and a support plate 24. The groove 21 is opened at one end of the first countersunk hole 20 near the outer side of the flange copper sleeve 10. One end of the support plate 24 is fixed to both ends of the support plate 23 and inserted into the groove 21.
[0031] The first countersunk hole 20 is filled with solid lubricant and is located at one end of the support plate 23 near the inner side of the flange copper sleeve 10.
[0032] The filter holes on the filter plate 22 are concentrated in the middle of the filter plate 22, and the diameter of the outer ring filter holes is smaller than the inner diameter of the guide hole on the inner side of the first countersunk hole 20.
[0033] The support plate 23 is fitted with the outer end of the first countersunk hole 20 with a small clearance.
[0034] The first countersunk hole 20 serves as the core accommodating cavity, providing installation space and channels for subsequent components. The groove 21 and the support plate 24 constitute a detachable limiting and locking mechanism. The filter plate 22 achieves dual control—acting as a physical barrier to intercept impurities and precisely regulating the flow rate of lubricant. The support plate 23 provides support and protection.
[0035] Working principle:
[0036] The first countersunk hole 20 and groove 21 are evenly opened on the flange copper sleeve 10. The filter plate 22 is placed into the first countersunk hole 20 and filled with fixing lubricant. Then the support plate 23 is placed into the first countersunk hole 20, so that the support plate 24 is inserted into the groove 21. Then the fixing lubricant is filled from the inside of the flange copper sleeve 10 into the guide hole at the rear end of the first countersunk hole 20. Finally, the flange copper sleeve 10 is put on the outside of the electric drive wheel.
[0037] This step forms a physical isolation layer, preventing external impurities from entering the first countersunk hole 20 and avoiding contamination of the lubricant.
[0038] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:
[0039] The pushing component includes an opening 30, a first movable plate 31, a spring 32, and a second movable plate 33. The opening 30 is located in the middle of the support plate 23. The first movable plate 31 and the second movable plate 33 are movably connected to both sides of the support plate 23. The spring 32 is fixed between the first movable plate 31 and the second movable plate 33 and is movably connected in the opening 30.
[0040] The push assembly also includes an arc plate 34, a fixing post 36, a mounting hole 37, and a second countersunk hole 38. There are two arc plates 34, which wrap around the outer side of the middle section of the flange copper sleeve 10. The fixing post 36 is fixed at both ends of the arc plate 34. The mounting hole 37 is opened in the middle of the fixing post 36. The second countersunk hole 38 is opened at both ends of the flange copper sleeve 10. The mounting hole 37 and the second countersunk hole 38 are fixed by screws.
[0041] The push assembly also includes a reinforcing rib 35, one end of which is fixed to the inner side of the arc plate 34, and the other end is attached to the outer side of the flange copper sleeve 10.
[0042] The diameters of the first movable plate 31 and the second movable plate 33 are smaller than the inner diameter of the outer end of the first countersunk hole 20;
[0043] The opening 30, the first movable plate 31, the spring 32, and the second movable plate 33 create an adaptive pressure transmission system. The arc plate 34 and the reinforcing rib 35 construct a high-strength support frame. The fixed column 36, the mounting hole 37, and the second countersunk hole 38, together with screws, achieve high-precision axial positioning.
[0044] Working principle:
[0045] One end of the spring 32 is fixed to one side of the first movable plate 31, and the other end of the spring 32 passes through the opening 30. The second movable plate 33 is then fixed to the spring 32. After installing the anti-damage component and filling it with lubricant, the flange copper sleeve 10 is placed on the outside of the electric transmission wheel. Then, two arc-shaped plates 34 are wrapped around the outside of the flange copper sleeve 10, so that the mounting hole 37 on the fixing post 36 is aligned with the second countersunk hole 38. The screws are screwed into the second countersunk hole 38 and the mounting hole 37. At this time, the arc-shaped plate 34 wrapped around the outside of the flange copper sleeve 10 presses the second movable plate 33 against the support plate 23. Due to the obstruction of the electric transmission wheel and the fixed lubricant, the spring 32 is compressed. When the electric transmission wheel is in use, the fixed lubricant is squeezed from the filter plate 22 onto the electric transmission wheel. As the lubricant decreases, the spring 32 extends, driving the first movable plate 31 to move inward toward the first countersunk hole 20, continuously pushing the remaining fixed lubricant out of the filter plate 22.
[0046] This step ensures a long-term supply of lubricant, further reduces the pathways for external contaminants to enter, and maintains the cleanliness of the lubrication system.
[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
