Description

Technical Field

[0001] This utility model relates to the field of composite gear technology, and in particular to a gear with a bimetallic composite locating pin structure. Background Technology

[0002] A gear is a mechanical component typically used to transmit power and change speed or direction. It transmits motion through the meshing of teeth and is widely used in various mechanical devices, such as automobiles, machine tools, and speed reducers, to meet different transmission requirements. A bimetallic composite locating pin structure is used to fix the copper alloy layer and the steel base together, ensuring a tight bond between the two materials and improving the overall structural stability.

[0003] A bimetallic composite locating pin gear is a gear design that combines two different metal materials (usually steel and copper alloy). This design forms a single structure by combining a copper alloy layer with a steel base gear. In existing gear technology, gears are often integrated structures, which can only be replaced as a whole when worn, resulting in high maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a gear with a bimetallic composite locating pin structure, which aims to improve the problem that in existing gear technology, gears are often an integral structure, and when they are worn, the whole unit can only be replaced, resulting in high maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gear with a bimetallic composite positioning pin structure, comprising an inner gear ring and a sliding assembly. An outer gear ring is provided on the outer wall of the inner gear ring. A groove is formed inside the outer gear ring. A threaded post is threadedly connected to the inner gear ring. A rotating block is fixedly connected to the top of the threaded post. The outer wall of the threaded post is threadedly connected to the inside of a limiting rod. The outer wall of the limiting rod is slidably connected to the inside of the inner gear ring. A connecting piece is fixedly connected to the outer wall of the limiting rod. A sliding piece is fixedly connected to the end of the limiting rod away from the connecting piece. A limiting assembly is provided on the outer wall of the sliding piece.

[0006] The above technical solution allows the rotating block to drive the threaded column to rotate and slide inside the gear inner ring. By sliding the threaded column into or out of the limiting post, the position of the limiting post inside the gear inner ring can be fixed or adjusted. When the limiting post restricts movement, it will limit the sliding plate, fixing it inside the gear inner ring.

[0007] Preferably, the limiting component includes a rod, the outer wall of which is fixedly connected to the outer wall of the slide plate, the outer wall of which is slidably connected to the inside of the gear inner ring, the outer wall of which abuts against the inner wall of the slot, and a first spring slidably connected to the outer wall of the rod, one end of which is fixedly connected to the outer wall of the slide plate, and the other end of which is fixedly connected to the inside of the gear inner ring.

[0008] Preferably, the sliding assembly includes a sliding column, the outer wall of which is slidably connected to the inside of the gear inner ring, and a pull tab is fixedly connected to the top of the sliding column.

[0009] Preferably, a fixing plate is slidably connected to the outer wall of the sliding column, one end of the fixing plate is fixedly connected to the inside of the gear inner ring, and the other end of the fixing plate is fixedly connected to a second spring.

[0010] Preferably, the outer wall of the second spring is slidably connected to the inside of the gear inner ring, and a fixing rod is fixedly connected to the lower surface of the second spring, with the outer wall of the fixing rod abutting against the inside of the limiting rod.

[0011] Preferably, the inner ring of the gear has symmetrically arranged second heat dissipation holes around its perimeter.

[0012] Preferably, the outer ring of the gear has symmetrically formed first heat dissipation holes around its perimeter.

[0013] Preferably, heat dissipation fins are symmetrically arranged around the inner ring of the gear, and heat dissipation through holes are uniformly opened inside the inner ring of the gear.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotating block drives the threaded column to rotate. Through the cooperation of the limiting rod, connecting piece, sliding piece, insert rod and first spring, the inner ring and outer ring of the gear can be assembled. The modular design facilitates the quick removal of the worn outer ring of the gear from the inner ring for partial replacement, thereby reducing maintenance costs.

[0016] 2. In this utility model, the combination of the first heat dissipation hole, the second heat dissipation hole, the heat dissipation fins and the heat dissipation through hole increases the heat dissipation area and promotes air flow, effectively dissipating heat to the surrounding environment.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a gear with a bimetallic composite positioning pin structure, including an inner gear ring 1 and a sliding component 11. The outer wall of the inner gear ring 1 is provided with an outer gear ring 2. The inner wall of the outer gear ring 2 is provided with a groove 3. The inner wall of the inner gear ring 1 is threadedly connected to a threaded post 4. The top end of the threaded post 4 is fixedly connected to a rotating block 5. The outer wall of the threaded post 4 is threadedly connected to the inside of a limiting rod 6. The outer wall of the limiting rod 6 is slidably connected to the inside of the inner gear ring 1. The outer wall of the limiting rod 6 is fixedly connected to a connecting piece 7. The end of the limiting rod 6 away from the connecting piece 7 is fixedly connected to a sliding piece 8. The outer wall of the sliding piece 8 is provided with a limiting component.

[0027] Specifically, the outer ring 2 of the gear is assembled on the outer wall of the inner ring 1 of the gear. Both the inner ring 1 and the outer ring 2 of the gear are made of metal. The outer ring 2 of the gear is in direct contact with other transmission components and is prone to wear after long-term use. Through modular design, the outer ring 2 of the gear can be replaced individually. The inner ring 1 of the gear supports the threaded column 4, and the threaded column 4 fixes the rotating block 5. By rotating the rotating block 5, the threaded column 4 can slide and rotate inside the inner ring 1 of the gear. The threaded column 4 restricts the position of the limiting rod 6 inside the inner ring 1 of the gear. When the threaded column 4 is stuck inside the limiting rod 6, it will fix the limiting rod 6. The limiting rod 6 fixes the connecting piece 7, thereby limiting and fixing the connecting piece 7.

[0028] Reference Figure 3 The limiting component includes a rod 9, the outer wall of the rod 9 is fixedly connected to the outer wall of the slide plate 8, the outer wall of the rod 9 is slidably connected to the inside of the gear inner ring 1, the outer wall of the rod 9 abuts against the inner wall of the slot 3, and a first spring 10 is slidably connected to the outer wall of the rod 9. One end of the first spring 10 is fixedly connected to the outer wall of the slide plate 8, and the other end of the first spring 10 is fixedly connected to the inside of the gear inner ring 1.

[0029] Specifically, the slider 8 supports and fixes the insert rod 9. When the slider 8 slides, it will drive the insert rod 9 to slide synchronously. The first spring 10 is set between the slider 8 and the inner ring 1 of the gear. The first spring 10 will be compressed due to the sliding of the slider 8. When the first spring 10 is not compressed, it will push the slider 8 to slide in the opposite direction through its own rebound. The inner ring 2 and the outer ring 1 of the gear can be fixed or disassembled by the insert rod 9 sliding into or out of the slot 3.

[0030] Example 2:

[0031] Reference Figure 1 and Figure 4 The sliding assembly 11 includes a sliding column 1101, the outer wall of which is slidably connected to the inside of the gear inner ring 1, and a pull tab 1102 is fixedly connected to the top of the sliding column 1101; a fixing plate 1103 is slidably connected to the outer wall of the sliding column 1101, one end of the fixing plate 1103 is fixedly connected to the inside of the gear inner ring 1, and the other end of the fixing plate 1103 is fixedly connected to a second spring 1104; the outer wall of the second spring 1104 is slidably connected to the inside of the gear inner ring 1, and a fixing rod 1105 is fixedly connected to the lower surface of the second spring 1104, with the outer wall of the fixing rod 1105 abutting against the inside of the limiting rod 6;

[0032] Specifically, the inner ring 1 of the gear supports the sliding column 1101, the sliding column 1101 fixes the pull plate 1102, and pulling the pull plate 1102 allows the sliding column 1101 to slide inside the inner ring 1 of the gear. The sliding column 1101 also fixes the fixing plate 1103, thereby allowing the fixing plate 1103 to slide synchronously inside the inner ring 1 of the gear. The second spring 1104 is placed between the fixing plate 1103 and the inner ring 1 of the gear. The second spring 1104 has a rebound function. When it is not compressed, it will push the fixing plate 1103 to slide in the opposite direction through its own rebound. The fixing plate 1103 fixes the fixing rod 1105, which can drive the fixing rod 1105 to slide synchronously. The fixing rod 1105 restricts the position of the limiting rod 6 inside the inner ring 1 of the gear.

[0033] Reference Figure 1 and Figure 5 The inner ring 1 of the gear is symmetrically provided with second heat dissipation holes 13 around its perimeter; the outer ring 2 of the gear is symmetrically provided with first heat dissipation holes 12 around its perimeter; heat dissipation fins 14 are symmetrically provided around the inner ring 1 of the gear, and heat dissipation through holes 15 are uniformly provided inside the inner ring 1 of the gear.

[0034] Specifically, the first heat dissipation hole 12 and the second heat dissipation hole 13 are symmetrically distributed around the inner ring 1 and the outer ring 2 of the gear, which can promote airflow to remove heat and improve heat dissipation efficiency. The heat dissipation fins 14 are usually made of aluminum alloy with high thermal conductivity. Setting them around the inner ring 1 of the gear can increase the heat dissipation area and improve heat dissipation efficiency. The heat dissipation through hole 15 can further improve the heat dissipation effect and ensure that heat can be quickly dissipated to the surrounding environment.

[0035] Working principle: When the compound gear is needed, the inner ring 1 and the outer ring 2 are used together. The outer ring 2 is prone to wear after long-term use. When the outer ring 2 needs to be replaced, the rotating block 5 drives the threaded column 4 to slide and rotate inside the inner ring 1. When the threaded column 4 slides inside the inner ring 1, it will slide out of the limit rod 6 at the same time, releasing the restriction on the limit rod 6. At this time, the first spring 10 is no longer squeezed. The first spring 10 will push the slide plate 8 to slide in the opposite direction through its own rebound. When the slide plate 8 slides, it will drive the insertion rod 9 to slide at the same time. When the insertion rod 9 slides out of the inner wall of the outer ring 2, the outer ring 2 can be removed from the outer wall of the inner ring 1.

[0036] Similarly, in another embodiment, pulling the pull tab 1102 causes the slide column 1101 to slide inside the inner ring 1 of the gear. When the slide column 1101 slides, it will cause the fixing plate 1103 to slide, and during the sliding process, it will squeeze the second spring 1104. When the fixing plate 1103 slides, it will also cause the fixing rod 1105 to slide, so that it slides out of the interior of the limiting rod 6. This can also release the restriction on the limiting rod 6, thereby sliding the insertion rod 9 out of the inner wall of the slot 3 and removing the outer ring 2 of the gear from the outer wall of the inner ring 1. This achieves the effect of quickly removing the worn outer ring 2 of the gear from the inner ring 1 for partial replacement through modular design, reducing maintenance costs.

[0037] During operation, the inner ring 1 and outer ring 2 of the gear generate a large amount of heat. Four sets of first heat dissipation holes 12 and second heat dissipation holes 13 are symmetrically arranged around the inner ring 1 and outer ring 2 to facilitate the dissipation of heat from inside the inner ring 1 and outer ring 2 to the outside. The heat dissipation fins 14 and heat dissipation through holes 15 can assist in heat dissipation, further improving the heat dissipation performance. This increases the heat dissipation area, promotes airflow, and effectively dissipates heat to the surrounding environment. The improved heat dissipation performance also reduces wear during use. This composite gear not only achieves the effect of quickly removing the worn outer ring 2 from the inner ring 1 for partial replacement through modular design, reducing maintenance costs, but also increases the heat dissipation area, promotes airflow, and effectively dissipates heat to the surrounding environment. The improved heat dissipation performance also reduces wear during use.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
