Description

Technical Field

[0001] This utility model relates to the field of mechanical component technology, specifically to an enhanced wear-resistant mechanical component structure. Background Technology

[0002] In the context of today's accelerated industrialization, various types of machinery and equipment are widely used in many key fields such as energy, transportation, manufacturing, and mining. Wear and tear on mechanical parts not only reduces the performance and precision of equipment and affects product quality, but also triggers a series of serious consequences.

[0003] A search revealed a utility model patent with Chinese patent publication number CN117823607A, which discloses a gear and gear reducer for a humanoid robot. The key technical features are: a housing, a first transmission shaft, a second transmission shaft, a first gear set, a second gear set, and an adjustment mechanism. The first and second transmission shafts are connected to the housing. The first gear set includes a first driving gear and a first driven gear. The second gear set includes a second driving gear and a second driven gear. The adjustment mechanism drives the second transmission shaft to move. When the second transmission shaft moves to a position where the first driving gear and the first driven gear are directly opposite each other, the first driving gear meshes with the first driven gear. When the second transmission shaft moves to a position where the second driving gear and the second driven gear are directly opposite each other, the second driving gear meshes with the second driven gear.

[0004] As mentioned above, the gears used in robots are usually made of non-metallic materials to reduce noise, weight and improve corrosion resistance. However, gears are always subject to friction during operation, so their wear resistance is particularly important. Utility Model Content

[0005] The purpose of this invention is to provide an enhanced wear-resistant mechanical component structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an enhanced wear-resistant mechanical component structure, comprising a gear body, wherein the gear body is made of a substrate as the main material, the substrate is made of polyetheretherketone material, carbon fiber and glass fiber are added inside the substrate, and a lubricating coating is sprayed on the outer surface of the gear body, the lubricating coating being made of polytetrafluoroethylene material.

[0007] This design ensures the overall strength and wear resistance of the gears while significantly reducing the coefficient of friction, thus greatly extending their service life. The base material provides fundamental performance protection for the gear body under high-temperature environments. The addition of glass fiber and carbon fiber further enhances the mechanical properties of the materials and reduces costs. The outermost lubricating coating effectively reduces wear and energy loss on the gear surface, comprehensively improving the performance and service life of the gear body under complex working conditions. The base material, specifically polyetheretherketone (PEEK), maintains excellent mechanical properties and chemical stability at high temperatures, exhibiting high strength, high modulus, and good toughness, and is resistant to various chemicals. The material exhibits excellent resistance. The added glass fiber significantly improves the tensile strength, flexural strength, and impact toughness of the material. Compared to pure PEEK, glass fiber reinforcement reduces material costs and helps the composite material maintain its performance at high temperatures. Carbon fiber provides excellent mechanical properties, giving the material lightweight and high strength, and maintaining stable performance under long-term cyclic loading. The outermost lubricating coating (PTFE) significantly reduces the coefficient of friction of the composite material, improves lubricity, and is resistant to various chemicals, helping the composite material maintain its performance in harsh environments. It can form a lubricating film on the gear surface, reducing wear and energy loss.

[0008] As a further preferred embodiment of this technical solution, an annular groove is provided in the middle of the outer wall on both sides of the gear body, and the two annular grooves are arranged parallel to the gear body. The same heat dissipation component is installed in both annular grooves.

[0009] As a further preferred embodiment of this technical solution, the heat dissipation assembly includes two contact rings slidably connected inside two annular grooves. Several heat dissipation fins are fixedly connected to the outer walls of the two contact rings on opposite sides. Two horizontally arranged screws are fixedly connected to the outer wall of one of the contact rings near the gear body. Two clearance holes are opened inside the gear body and the other contact ring. The two screws pass through the two clearance holes and extend outward. A nut is threaded to the outside of each of the two screws. Both nuts are in contact with the surface of the other contact ring.

[0010] Insert the two contact rings into the two annular grooves respectively, with the part that will install the heat sink facing outwards. After the insertion is completed, the screw on the outside of one of the contact rings will pass through the clearance hole and the other contact ring and extend outwards. Then screw the nut into the threaded part of the screw to fix the two contact rings and the annular grooves into one piece. The heat sink can greatly increase the contact area between the gear body and the air, thereby ensuring that the heat generated by the gear body during operation can be dissipated more quickly.

[0011] As a further preferred embodiment of this technical solution, the contact ring, heat sink, and screw are all made of aluminum alloy, and the thread helix angle of the external thread of the screw is less than the equivalent friction angle.

[0012] As a further preferred embodiment of this technical solution, graphene nanomaterials are added to the substrate, and the proportion of graphene is 0.1%-5%.

[0013] As a further preferred embodiment of this technical solution, the proportion of carbon fiber is 5%-20%.

[0014] As a further preferred embodiment of this technical solution, the proportion of glass fiber is 10%-30%.

[0015] This utility model provides an enhanced wear-resistant mechanical component structure, which has the following beneficial effects:

[0016] (1) By setting a base material, carbon fiber, glass fiber and lubricating coating, this utility model can ensure the overall strength and wear resistance of the gear, while also greatly reducing the friction coefficient of the gear, thus greatly increasing the service life of the gear. The base material provides basic performance guarantee for the gear body in high temperature environment. The addition of glass fiber and carbon fiber further enhances the mechanical properties of the material and reduces the cost. The outermost lubricating coating effectively reduces wear and energy loss on the gear surface, comprehensively improving the performance and service life of the gear body under complex working conditions.

[0017] (2) By setting up a heat dissipation component, the two contact rings are respectively inserted into the two annular grooves, and the part of the heat sink is set to face outward. After the insertion work is completed, the screw outside one of the contact rings will pass through the clearance hole and the other contact ring and extend outward. Then, the nut is screwed into the threaded part of the screw, and the two contact rings and the annular grooves are fixed together. The heat sink can greatly increase the contact area between the gear body and the air, thereby ensuring that the heat generated by the gear body during operation can be dissipated more quickly.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, an enhanced wear-resistant mechanical component structure includes a gear body 1. The gear body 1 is made of a substrate 101 as the main material. The substrate 101 is made of polyetheretherketone material. Carbon fiber 102 and glass fiber 103 are added inside the substrate 101. A lubricating coating 104 is sprayed on the outer surface of the gear body 1. The lubricating coating 104 is made of polytetrafluoroethylene material.

[0025] The gear body 1 is made using melt blending control technology, with substrate 101 as the main material, specifically polyetheretherketone (PEEK). It maintains excellent mechanical properties and chemical stability at high temperatures, possesses high strength, high modulus, and good toughness, and exhibits excellent resistance to various chemicals. The added glass fiber 103 significantly improves the tensile strength, flexural strength, and impact toughness of the material. Compared to pure PEEK, glass fiber reinforcement reduces material costs and also helps maintain the performance of the composite material at high temperatures. Carbon fiber 102 provides excellent mechanical properties, giving the material lightweight and high strength characteristics, and maintaining stable performance under long-term cyclic loads. The outermost lubricating coating 104 (polytetrafluoroethylene) significantly reduces the coefficient of friction of the composite material, improves lubricity, and resists various chemicals, helping the composite material maintain its performance in harsh environments. It can form a lubricating film on the gear surface, reducing wear and energy loss.

[0026] like Figure 2 and Figure 3 As shown, an annular groove 2 is provided in the middle of the outer wall on both sides of the gear body 1, and the two annular grooves 2 are parallel to the gear body 1. The same heat dissipation component 3 is installed in the two annular grooves 2.

[0027] The heat dissipation assembly 3 includes two contact rings 301 that are slidably connected inside two annular grooves 2. Several heat sinks 302 are fixedly connected to the outer walls of the two contact rings 301 on the side away from each other. Two horizontally arranged screws 303 are fixedly connected to the outer wall of one of the contact rings 301 near the gear body 1. Two clearance holes 304 are opened inside the gear body 1 and the other contact ring 301. The two screws 303 pass through the two clearance holes 304 and extend outward. A nut 305 is threaded to the outside of each of the two screws 303. The two nuts 305 are in contact with the surface of the other contact ring 301.

[0028] The contact ring 301, heat sink 302 and screw 303 are all made of aluminum alloy, which ensures sufficient heat dissipation without increasing the weight excessively. In addition, the thread helix angle of the external thread of screw 303 is less than the equivalent friction angle, giving it a self-locking property.

[0029] Two contact rings 301 are inserted into the two annular grooves 2 respectively, with the part of the heat sink 302 facing outward. After the insertion is completed, the screw 303 on the outside of one of the contact rings 301 will pass through the clearance hole 304 and the other contact ring 301 and extend outward. Then, the nut 305 is screwed into the threaded part of the screw 303, which can fix the two contact rings 301 and the annular groove 2 into one piece. The heat sink 302 can greatly increase the contact area between the gear body 1 and the air, thereby ensuring that the heat generated by the gear body 1 during operation can be dissipated more quickly.

[0030] like Figure 1 and Figure 2 As shown, graphene nanomaterials are added inside the substrate 101, and the proportion of graphene is 0.1%-5%. By forming a lubricating layer or reducing the coefficient of friction, the wear rate is reduced. The addition of nano-additives can increase the thermal decomposition temperature of the composite material, which helps to improve the performance of the composite material in applications that require heat dissipation.

[0031] like Figure 4 As shown, carbon fiber 102 accounts for 5%-20%.

[0032] like Figure 4 As shown, the proportion of glass fiber 103 is 10%-30%. The addition of this material can reduce material costs compared to pure PEEK.

[0033] This utility model provides an enhanced wear-resistant mechanical component structure, the specific working principle of which is as follows:

[0034] When the device is working, the two contact rings 301 are respectively inserted into the two annular grooves 2, with the part of the heat sink 302 facing outward. After the insertion is completed, the screw 303 outside one of the contact rings 301 will pass through the clearance hole 304 and the other contact ring 301 and extend outward. Then, the nut 305 is screwed into the threaded part of the screw 303, which can fix the two contact rings 301 and the annular groove 2 into one piece. The heat sink 302 can greatly increase the contact area between the gear body 1 and the air, thereby ensuring that the heat generated by the gear body 1 during operation can be dissipated more quickly.

[0035] The gear body 1 is made using melt blending control technology, with substrate 101 as the main material, specifically polyetheretherketone (PEEK). It maintains excellent mechanical properties and chemical stability at high temperatures, possesses high strength, high modulus, and good toughness, and exhibits excellent resistance to various chemicals. The added glass fiber 103 significantly improves the tensile strength, flexural strength, and impact toughness of the material. Compared to pure PEEK, glass fiber reinforcement reduces material costs and also helps maintain the performance of the composite material at high temperatures. Carbon fiber 102 provides excellent mechanical properties, giving the material lightweight and high strength characteristics, and maintaining stable performance under long-term cyclic loads. The outermost lubricating coating 104 (polytetrafluoroethylene) significantly reduces the coefficient of friction of the composite material, improves lubricity, and resists various chemicals, helping the composite material maintain its performance in harsh environments. It can form a lubricating film on the gear surface, reducing wear and energy loss.
