Description

Technical Field

[0001] This utility model relates to the field of bushing technology, specifically to an alloy bushing. Background Technology

[0002] Alloy bushings are mechanical components made of two or more metals or metals and non-metallic elements. They are fitted onto shafts or other components to provide protection, support, and friction reduction. Common types include copper alloys, iron-based alloys, and hard alloys. They possess high strength, wear resistance, self-lubrication, corrosion resistance, and vibration and noise reduction properties. Manufactured using powder metallurgy, casting, and machining processes, they are widely used in various fields such as automotive, machinery manufacturing, petrochemical, aerospace, and construction machinery. They reduce friction, ensure equipment accuracy and stability, and adapt to different working conditions.

[0003] This application improves upon the existing technology. In the prior art, existing bushings are mostly made of alloy materials to improve wear resistance. However, in actual use, although alloy bushings can improve wear resistance, the inner wall of the alloy bushing is relatively smooth and cannot store lubricating oil, which will reduce the wear resistance of the bushing to a certain extent and result in poor performance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide an alloy bushing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an alloy bushing, comprising an alloy bushing body, wherein multiple grooves are formed on the inner wall of the alloy bushing body, and oil injection holes are formed symmetrically on the inner wall of the grooves. An annular groove is formed on the outer wall of the alloy bushing body on the side of two oil injection holes that are far apart from each other. Multiple slots are formed in an annular array on the outer side of the annular groove. A locking block is movably disposed inside the slot, and a filter screen plate is fixedly connected to the inner side of the locking block.

[0007] As a further embodiment of this utility model: the number of grooves is not less than three, and the depth of the grooves is 0.1-0.5mm.

[0008] As a further embodiment of this utility model: the diameter of the groove is 5-10mm, and the distance between two adjacent grooves is 10-20mm.

[0009] As a further embodiment of this utility model: a screw hole is provided through the surface of the card block, and a screw is threadedly connected to the inner wall of the screw hole.

[0010] As a further embodiment of this utility model: each of the filter screens has four locking blocks on its outer wall, and the filter screen and the locking blocks are an integral die-cast structure.

[0011] As a further embodiment of this utility model: the mesh on the filter plate is made of stainless steel and the mesh density is 200 mesh.

[0012] This utility model has the following beneficial effects:

[0013] (1) By setting grooves and oil injection holes, during the process of oil injection and lubrication through the oil injection holes, multiple grooves can be set to store lubricating oil. The grooves are evenly distributed and can form an oil film to isolate the friction surface, reducing direct metal contact under dry friction conditions, thereby improving the wear resistance of the bushing. This solves the problem that existing bushings are mostly made of alloy materials to improve wear resistance. However, in actual use, although alloy bushings can improve wear resistance, the inner wall of the alloy bushing is relatively smooth and cannot store lubricating oil, which will reduce the wear resistance of the bushing to a certain extent and result in poor performance.

[0014] (2) Through the structural design of the annular groove, slot, block, screw hole, screw and filter screen, the oil filling hole can be protected by the filter screen, which can effectively prevent dust or debris from entering the oil filling hole. The screw can be rotated with a tool until one end of the screw is disengaged from the screw hole. Then the filter screen is moved along the outside until the filter screen is disengaged from the annular groove, thus completing the disassembly of the filter screen. Similarly, the filter screen can be installed. By making it easy to disassemble, clean and install the filter screen, the filtration effect can be effectively guaranteed, and thus better ensure that oil is injected through the oil filling hole.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-5An embodiment of this utility model is provided: an alloy bushing, including an alloy bushing body 1, a plurality of grooves 2 are formed on the inner wall of the alloy bushing body 1, the number of grooves 2 is not less than three, the depth of the grooves 2 is 0.1-0.5mm, the diameter of the grooves 2 is 5-10mm, the distance between two adjacent grooves 2 is 10-20mm, and oil injection holes 3 are formed on the inner wall of the grooves 2 in a centrally symmetrical manner.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during use, when lubricating through the oil injection hole 3, the multiple grooves 2 can store lubricating oil. The grooves 2 are evenly distributed and can form an oil film to isolate the friction surface, reducing direct metal-to-metal contact under dry friction conditions. This improves the wear resistance of the bushing and solves the problem that existing bushings often use alloy materials to improve wear resistance. However, in actual use, although alloy bushings can improve wear resistance, their smooth inner walls cannot store lubricating oil, which reduces the wear resistance of the bushing to a certain extent and results in poor performance.

[0028] On the outer wall of the alloy bushing body 1, there is an annular groove 4 on the side of the two oil injection holes 3 that are far apart from each other. Multiple slots 5 are arranged in a ring array on the outer side of the annular groove 4. A locking block 6 is movably arranged inside the slot 5. A filter screen plate 9 is fixedly connected to the inner side of the locking block 6. A screw hole 7 is opened through the surface of the locking block 6. A screw rod 8 is threadedly connected to the inner wall of the screw hole 7. Four locking blocks 6 are arranged on the outer wall of each filter screen plate 9. The filter screen plate 9 and the locking block 6 are an integral die-cast structure. The mesh on the filter screen plate 9 is made of stainless steel and the mesh density is 200 mesh.

[0029] Specifically, such as Figure 4 and Figure 5 As shown, during use, the filter screen 9 can protect the oil filling hole 3, effectively preventing dust or debris from entering the oil filling hole 3. The screw 8 can be rotated with a tool until one end of the screw 8 disengages from the screw hole 7. Then, the filter screen 9 can be moved along the outside until it disengages from the annular groove 4, thus completing the disassembly of the filter screen 9. Similarly, the filter screen 9 can be installed. By facilitating the disassembly, cleaning, and installation of the filter screen 9, its filtration effect can be effectively guaranteed, thereby ensuring better oil filling through the oil filling hole 3.

[0030] Working principle: In this application, during the lubrication process through the oil injection hole 3, the multiple grooves 2 can store lubricating oil, and the grooves 2 are evenly distributed to form an oil film that isolates the friction surface, reducing direct metal-to-metal contact under dry friction conditions, thereby improving the wear resistance of the bushing. Secondly, the oil injection hole 3 can be protected by the filter screen plate 9, which can effectively prevent dust or debris from entering the oil injection hole 3. The screw 8 can be rotated with a tool until one end of the screw 8 is disengaged from the screw hole 7, and then the filter screen plate 9 can be moved along the outside until it is disengaged from the annular groove 4, thus completing the disassembly of the filter screen plate 9. Similarly, the filter screen plate 9 can be installed. By facilitating the disassembly, cleaning and installation of the filter screen plate 9, its filtration effect can be effectively guaranteed, thereby better ensuring the lubrication through the oil injection hole 3.

[0031] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. At the same time, the electrical components mentioned in this application are all connected to an external power supply and control switch when in use. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Therefore, this utility model will not explain the control method and circuit connection in detail. Moreover, the external controller mentioned in the specification can play a control role for the electrical components mentioned in this article, and the external controller is a conventional known device.
