Description

Technical Field

[0001] This utility model relates to the field of split copper sleeve technology, specifically a split wear-resistant copper sleeve. Background Technology

[0002] Split-type copper bushings are mechanical transmission and connection components that split traditional one-piece copper bushings axially or radially to form two or more assemblable units (commonly two half-copper bushings). Their core material is mainly copper alloy, such as tin bronze, aluminum bronze, and brass, which combines the wear resistance, thermal conductivity, and corrosion resistance of copper itself. At the same time, the "split design" overcomes the limitations of one-piece copper bushings in terms of installation, maintenance, and adaptation scenarios, making them an important supporting component for shaft parts and sleeve structures in industrial equipment. They are widely applicable to transmission systems, hydraulic devices, engineering machinery, and other scenarios. In the fields of industrial equipment transmission, hydraulic systems, and mechanical connections, split-type copper bushings have become an important component to replace integrated copper bushings because they are easy to install on shaft parts or sleeve structures and can be disassembled for partial maintenance and replacement. Traditional split-type copper bushings mostly use bolt connections to fix the two halves of the copper bushing. Due to the "long-term and unstable" vibration load of large equipment, the bolts connected to the outside of the copper bushing will be subjected to alternating stress during continuous vibration. Especially at the transition between the bolt head and the screw, and at the root of the thread, micro-cracks are prone to appear due to stress concentration. As the equipment operates for longer, the cracks will continue to expand, leading to a decrease in bolt strength. When the stress exceeds the fatigue limit of the bolt, the bolt may break directly, resulting in the two copper bushings falling off and affecting the normal operation of the equipment. Therefore, a split-type wear-resistant copper bushing is proposed to address the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a split-type wear-resistant copper sleeve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A split-type wear-resistant copper sleeve includes a first half-copper sleeve and a second half-copper sleeve. An anti-detachment mechanism is provided between the first half-copper sleeve and the second half-copper sleeve. An installation mechanism is fixedly connected to the top of the anti-detachment mechanism. The anti-fall-off mechanism includes a first stabilizing block and a second stabilizing block. A snap-fit ​​plate is fixedly connected to the outer side of the first stabilizing block, and an elastic rubber plate is provided on the outer side of the snap-fit ​​plate. A connecting groove is opened inside the second stabilizing block, and a slot is opened in the inner wall of the connecting groove. A stabilizing cover is fixedly connected to the top of the second stabilizing block, and a moving rod is slidably snapped to the bottom of the stabilizing cover. A positioning ball is fixedly connected to the bottom of the moving rod, and a compression spring is sleeved on the moving rod. A ball groove is opened on the top of the snap-fit ​​plate.

[0005] As a further optimization of this utility model, the installation mechanism includes a first fixing plate and a second fixing plate. The first fixing plate is internally threaded with a screw rod, and a rotating cover is fixedly connected to the outside of the screw rod.

[0006] As a further optimization of this utility model, the first half-copper sleeve and the second half-copper sleeve have the same specifications, the first stabilizing block is fixedly connected to the outside of the first half-copper sleeve, and the second stabilizing block is fixedly connected to the outside of the second half-copper sleeve.

[0007] As a further optimization of this utility model, the first stabilizing block and the second stabilizing block are evenly distributed on the outer sides of the first half copper sleeve and the second half copper sleeve, and the snap-fit ​​plate and the connecting groove are on the same plane.

[0008] As a further optimization of this utility model, the elastic rubber sheet is evenly and symmetrically distributed on the outer side of the snap-fit ​​plate, and there is a certain inclination angle between the elastic rubber sheet and the snap-fit ​​plate.

[0009] As a further optimization of this utility model, the following features are provided: the slot is adapted to the elastic rubber plate, the positioning ball is movably connected inside the connecting groove, and the positioning ball is adapted to the ball groove, with a chamfer on the edge of the ball groove.

[0010] As a further optimization of this utility model, the first fixing plate is fixedly connected to the top of the first stabilizing block, the second fixing plate is fixedly connected to the top of the second stabilizing block, and the end of the screw away from the first fixing plate is rotatably engaged inside the second fixing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the dual-fixing design of the anti-detachment mechanism plays a crucial role. On the one hand, when the snap-fit ​​plate on the first stabilizing block is inserted into the connecting groove of the second stabilizing block, the outer elastic rubber plate can precisely fit and engage with the snap-fit ​​groove on the inner wall of the connecting groove. With the elastic tension of the elastic rubber plate, a preliminary stable connection is formed, preventing the snap-fit ​​plate from shaking in the connecting groove. On the other hand, the moving rod at the bottom of the stabilizing cover, under the action of the compression spring, drives the positioning ball to be tightly embedded in the ball groove at the top of the snap-fit ​​plate. The chamfered design of the edge of the ball groove facilitates the smooth insertion of the positioning ball, further limiting and fixing the snap-fit ​​plate longitudinally. The dual-fixing structure greatly enhances the connection stability between the first and second half copper sleeves, effectively preventing the copper sleeves from falling off under transmission, vibration and other working conditions, and ensuring the normal operation of the equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A split-type wear-resistant copper sleeve includes a first half copper sleeve 1 and a second half copper sleeve 2. An anti-dropping mechanism 3 is provided between the first half copper sleeve 1 and the second half copper sleeve 2. An installation mechanism 4 is fixedly connected to the top of the anti-dropping mechanism 3. The anti-fall-off mechanism 3 includes a first stabilizing block 31 and a second stabilizing block 32. A snap-fit ​​plate 33 is fixedly connected to the outside of the first stabilizing block 31. An elastic rubber plate 34 is provided on the outside of the snap-fit ​​plate 33. A connecting groove 35 is opened inside the second stabilizing block 32. A slot 36 is opened in the inner wall of the connecting groove 35. A stabilizing cover 37 is fixedly connected to the top of the second stabilizing block 32. A moving rod 38 is slidably snapped to the bottom of the stabilizing cover 37. A positioning ball 39 is fixedly connected to the bottom of the moving rod 38. A compression spring 310 is sleeved on the moving rod 38. A ball groove 311 is opened on the top of the snap-fit ​​plate 33.

[0017] It should be noted that: the No. 1 half copper sleeve 1 and the No. 2 half copper sleeve 2 have the same specifications. The No. 1 stabilizing block 31 is fixedly connected to the outside of the No. 1 half copper sleeve 1, and the No. 2 stabilizing block 32 is fixedly connected to the outside of the No. 2 half copper sleeve 2. The No. 1 stabilizing block 31 and the No. 2 stabilizing block 32 are evenly distributed on the outside of the No. 1 half copper sleeve 1 and the No. 2 half copper sleeve 2. The snap-fit ​​plate 33 and the connecting groove 35 are on the same plane.

[0018] Furthermore: the elastic rubber plate 34 is evenly and symmetrically distributed on the outside of the snap-fit ​​plate 33, and there is a certain inclination angle between the elastic rubber plate 34 and the snap-fit ​​plate 33. The snap-fit ​​groove 36 is adapted to the elastic rubber plate 34. The positioning ball 39 is movably connected inside the connecting groove 35, and the positioning ball 39 is adapted to the ball groove 311. The edge of the ball groove 311 is chamfered.

[0019] Specifically, the distribution of stabilizing blocks 31 and 32 is not simply "equally spaced". Instead, it needs to be designed in combination with the stress characteristics of the copper sleeve. For example, if the copper sleeve is often used in high-frequency vibration scenarios, the stabilizing blocks need to be densely distributed on both sides of the vibration direction to enhance vibration resistance. If it is used in a working condition with large transmission torque, 3-4 sets of stabilizing blocks need to be evenly set around the circumference of the copper sleeve to ensure uniform torque transmission and avoid excessive local stress that could cause the stabilizing blocks to break. In addition, the fixing method of the two also needs to match the copper sleeve material and the operating temperature. If the copper sleeve is used in a high-temperature environment, high-temperature resistant welding materials should be selected for welding to prevent connection point failure at high temperatures.

[0020] Furthermore, the combination of the "uniform and symmetrical distribution" and "tilted angle" of the elastic rubber plate 34 ensures force balance during snap-fitting and achieves "one-way snap-fitting" through the tilt angle. When inserted into the connecting groove 35, the tilted surface reduces resistance and facilitates quick docking. When the copper sleeve tends to separate under external force, the vertical surface of the elastic rubber plate 34 will fit tightly against the inner wall of the groove 36, forming a "reverse lock" that greatly improves the resistance to detachment. At the same time, the rubber material must be oil-resistant and aging-resistant nitrile rubber or fluororubber to avoid elastic failure caused by corrosion from equipment lubricating grease.

[0021] As a further implementation of this scheme, the installation mechanism 4 includes a first fixing plate 41 and a second fixing plate 42. The first fixing plate 41 is internally threaded with a screw 43, and the outside of the screw 43 is fixedly connected with a rotating cover 44.

[0022] It should be noted that: the first fixing plate 41 is fixedly connected to the top of the first stabilizing block 31, the second fixing plate 42 is fixedly connected to the top of the second stabilizing block 32, and the end of the screw 43 away from the first fixing plate 41 is rotatably engaged inside the second fixing plate 42.

[0023] Furthermore, the No. 1 fixing plate 41 and the No. 2 fixing plate 42 serve as the core components for fastening, ensuring that the fixing plates will not deform when the screw 43 is turned. In addition, the "rotation snap-fit ​​structure" inside the No. 2 fixing plate 42 needs to match the end of the screw 43. If used in high-precision equipment, a miniature bearing can be added between the two to reduce rotational friction and make the operation of the rotating cover 44 easier.

[0024] Workflow: First, align the No. 1 half copper sleeve 1 and No. 2 half copper sleeve 2 of the same specifications to the installation position. Since the No. 1 stabilizing block 31 fixed on the outside of the No. 1 half copper sleeve 1 and the No. 2 stabilizing block 32 fixed on the outside of the No. 2 half copper sleeve 2 are evenly distributed and their snap-fit ​​plates 33 and connecting grooves 35 are on the same plane, the snap-fit ​​plate 33 on the No. 1 stabilizing block 31 can be directly inserted into the connecting groove 35 of the No. 2 stabilizing block 32. During the insertion process, the elastic rubber plate 34 with an inclined angle on the outer side of the snap-fit ​​plate 33 will automatically engage with the snap-fit ​​groove 36 that matches the inner wall of the connecting groove 35 to form a preliminary fixation. At the same time, the moving rod 38 that is slidably snapped at the bottom of the top stabilizing cover 37 of the No. 2 stabilizing block 32, under the elastic force of the compression spring 310 sleeved on its outer side, drives the bottom positioning ball 39 to move downward. The chamfered design of the edge of the ball groove 311 at the top of the snap-fit ​​plate 33 makes it easy for the positioning ball 39 to be smoothly embedded into the ball groove 311, further limiting the snap-fit ​​plate 33 longitudinally and completing the double fixation of the anti-drop mechanism 3. Next, the installation mechanism 4 is used for final tightening. Since the first fixing plate 41 is fixed to the top of the first stabilizing block 31 and the second fixing plate 42 is fixed to the top of the second stabilizing block 32, rotating the rotating cover 44 on the outside of the screw 43 can drive the screw 43, which is threadedly connected to the first fixing plate 41, to rotate. The end of the screw 43 away from the first fixing plate 41 rotates and engages inside the second fixing plate 42, thereby bringing the first fixing plate 41 and the second fixing plate 42 closer together, achieving precise fitting and fixing of the first half copper sleeve 1 and the second half copper sleeve 2. When disassembling, rotating the rotating cover 44 in the opposite direction will loosen the screw 43. Then, external force is applied to make the elastic rubber plate 34 disengage from the slot 36 and the positioning ball 39 disengage from the ball groove 311, so that the snap-fit ​​plate 33 can be pulled out from the connecting groove 35, completing the disassembly of the two half copper sleeves.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
