Description

A high-temperature resistant timing chain guide rail Technical Field

[0001] This utility model relates to the field of chain guide technology, and in particular to a high-temperature resistant timing chain guide. Background Technology

[0002] The timing chain guide is an important component of the engine. It works in conjunction with the tensioner to ensure that the timing chain always has a stable tension, preventing the timing chain from derailing. During transport, the timing chain is conveyed along the track of the guide groove on the timing chain guide.

[0003] Currently, conventional timing chain guides are integrally molded structures. Prolonged use can lead to cracks in the guides, and damage requires replacement of the entire system, which is wasteful. Furthermore, prolonged use can cause the chain to lack lubrication, resulting in increased friction and reducing the lifespan of both the guides and the chain. In addition, they are generally made of metal, making them heavy and resulting in poor performance.

[0004] Therefore, those skilled in the art have provided a high-temperature resistant timing chain guide to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-temperature resistant timing chain guide. The guide allows for individual replacement via a designed disassembly mechanism, avoiding waste and simplifying operation. Furthermore, the wear-resistant mechanism reduces the guide's weight, and by modifying traditional metal materials, the guide exhibits excellent wear and high-temperature resistance, thereby extending its service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-temperature resistant timing chain guide rail includes a fixed base, wherein a wear-resistant mechanism is provided inside the fixed base, and a disassembly mechanism is provided inside the fixed base.

[0008] The disassembly mechanism includes a fixed base, and cavities are opened inside one end of the outer wall of the fixed base. A locking rod is provided at one end of the outer wall of the fixed base, and one end of the locking rod extends into the cavity. A spring is provided inside the cavity, and the spring is sleeved on the locking rod and located on the inner wall inside the cavity.

[0009] The above technical solution allows for the individual replacement of the guide rails via a designed disassembly mechanism, avoiding waste and simplifying the operation.

[0010] Furthermore, the wear-resistant mechanism includes a guide rail body, the guide rail body has a high-temperature resistant layer inside, and a reinforcing layer is provided on one side of the outer wall of the high-temperature resistant layer;

[0011] The above technical solution, through the wear-resistant mechanism, can reduce the weight of the guide rail while changing the traditional metal material to give the guide rail excellent wear and high temperature resistance, thereby improving the service life of the guide rail.

[0012] Furthermore, the bottom end of the guide rail body is provided with two locking blocks on both sides, and the outer wall of the locking block is provided with a locking groove, and the locking groove and the locking rod are engaged and connected.

[0013] The above technical solution allows the guide rail body to be fixed in place through the cooperation between the slot and the lever.

[0014] Furthermore, the outer wall of the guide rail body is coated with ultra-high molecular weight polyethylene material;

[0015] Through the above technical solutions, ultra-high molecular weight polyethylene material exhibits excellent self-lubrication and wear resistance, which can reduce chain wear and noise during high-speed operation.

[0016] Furthermore, the high-temperature resistant layer material is set as high-temperature nylon material;

[0017] Through the above technical solutions, high-temperature nylon materials possess high rigidity and excellent high-temperature resistance.

[0018] Furthermore, the reinforcing layer material is configured as a modified polyoxymethylene material;

[0019] Through the above technical solutions, the modified polyoxymethylene material has high rigidity.

[0020] Furthermore, a plurality of oil outlet chambers are provided on one side of the inner wall of the fixed base, and an oil inlet is provided on one side of the outer wall of the fixed base, with the oil inlet and oil outlet chambers cooperating with each other;

[0021] Through the above technical solution, lubricating oil can be added to the inside of the guide rail by the cooperation between the oil inlet and the oil outlet, thereby reducing the internal friction.

[0022] Furthermore, through holes are provided at both ends of one side of the outer wall of the fixing base;

[0023] The above technical solution allows the mounting bracket to be installed in the designated location.

[0024] This utility model has the following beneficial effects:

[0025] 1. The high-temperature resistant timing chain guide proposed in this utility model allows for quick replacement of the guide rail through the cooperation of the locking rod, locking block, and spring. This convenient operation avoids damage to the chain caused by damage to the guide rail. At the same time, the guide rail and the fixing seat are manufactured separately, which can effectively avoid cracking that would require the replacement of the entire guide rail and fixing seat, thus saving costs.

[0026] 2. The high-temperature resistant timing chain guide proposed in this utility model improves the performance of the guide by the cooperation of multiple layers of materials. At the same time, changing the material to plastic reduces the weight of the guide, making it easier to install and use. The multiple layers of materials also increase the service life of the guide. Furthermore, the cooperation between the oil inlet and the oil outlet allows for timely addition of lubricating oil to the guide, thereby reducing the friction between the chain and the guide and further extending the service life of both the chain and the guide.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Referring to Figures 1-3, a specific embodiment of this utility model is provided: a high-temperature resistant timing chain guide rail, including a fixed base 101, a wear-resistant mechanism 2 is provided inside the fixed base 101, and a disassembly mechanism 1 is provided inside the fixed base 101.

[0036] The disassembly mechanism 1 includes a fixed base 101. A cavity 102 is opened inside one end of the outer wall of the fixed base 101. A locking rod 104 is provided at one end of the outer wall of the fixed base 101. One end of the locking rod 104 extends into the cavity 102. A spring 103 is provided inside the cavity 102. The spring 103 is sleeved on the locking rod 104 and located on the inner wall of the cavity 102. With the disassembly mechanism 1, the guide rail can be replaced individually, avoiding waste and making the operation simple.

[0037] Referring to Figures 1, 4, and 5, the wear-resistant mechanism 2 includes a guide rail body 201. A high-temperature resistant layer 202 is disposed inside the guide rail body 201, and a reinforcing layer 203 is disposed on one side of the outer wall of the high-temperature resistant layer 202. Through the wear-resistant mechanism 2, the weight of the guide rail can be reduced, and by changing the traditional metal material, the guide rail has excellent wear and high-temperature resistance, thereby improving the service life of the guide rail. Two locking blocks 105 are disposed on both sides of the bottom end of the guide rail body 201. The outer wall of the locking blocks 105 has a locking groove 106, which engages with a locking rod 104. Through the cooperation between the locking groove 106 and the locking rod 104, the guide rail body 201 can be fixed in place. The outer wall of the guide rail body 201 is coated with ultra-high molecular weight polyethylene material. The polyethylene material has excellent self-lubrication and good wear resistance, which can reduce chain wear and noise during high-speed operation. The high-temperature resistant layer 202 is made of high-temperature nylon, which has high rigidity and good high-temperature resistance. The reinforcing layer 203 is made of modified polyoxymethylene, which has high rigidity. Multiple oil outlet chambers 4 are provided on one side of the inner wall of the fixed seat 101, and an oil inlet 5 is provided on one side of the outer wall of the fixed seat 101. The oil inlet 5 and the oil outlet chambers 4 cooperate with each other. Through the cooperation between the oil inlet 5 and the oil outlet chambers 4, lubricating oil can be added to the guide rail, thereby reducing its internal friction. Through holes 3 are opened at both ends of one side of the outer wall of the fixed seat 101 to install the fixed seat 101 in the designated position.

[0038] Working principle: When the guide rail needs to be replaced after a long period of use, pull the lever 104 outward to disengage the lever 104 from the slot 106, allowing the guide rail body 201 to be directly removed from the fixed base 101. During installation, simply place the guide rail body 201 in the corresponding position on the fixed base 101, then release the lever 104. The spring 103 will reset, allowing the lever 104 and slot 106 to re-engage, thus fixing the guide rail body 201 in place. After a period of use, add oil to the oil outlet 4 through the oil inlet 5 to keep the guide rail body 201 and chain lubricated. Since the outer wall of the guide rail body 201 is coated with ultra-high molecular weight polyethylene, it has excellent wear resistance and lubricity, avoiding frequent oil additions. Furthermore, the guide rail body 201 is internally constructed with high-temperature nylon and modified polyoxymethylene, providing high rigidity and excellent high-temperature resistance.
