Description

Technical Field

[0001] This utility model relates to the field of friction disc technology, specifically a high wear-resistant nylon friction disc. Background Technology

[0002] A friction disc is a mechanical component that relies on contact surface friction to transmit power and achieve braking or clutch functions. It is widely used in automobiles, machine tools, construction machinery, and other equipment. During operation, it continuously withstands friction, pressure, and wear caused by relative motion. If its wear resistance is insufficient, it will lead to rapid wear of the contact surface and increased gaps. This will not only reduce power transmission efficiency and cause vibration or abnormal noise, but may also create safety hazards due to braking or clutch failure.

[0003] However, existing friction discs may be made of ordinary materials, which are prone to wear during long-term friction, resulting in a short service life and the need for frequent replacement. In addition, a lot of heat is generated during operation due to friction. If the heat generated by friction cannot be dissipated in time, the high temperature will cause the friction disc material performance to degrade, or even cause overheating failure. Summary of the Invention

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1 to 4 This utility model discloses a high-wear-resistant nylon friction disc, comprising a friction disc body 1, a wear-resistant layer 2 fixedly connected to the outer surface of the friction disc body 1, heat dissipation grooves 3 provided on the outer surface of the wear-resistant layer 2, a reinforcing layer 4 fixedly connected to the inner wall of the wear-resistant layer 2, a buffer layer 5 fixedly connected to the inner wall of the reinforcing layer 4, a positioning sleeve 6 fixedly connected to the center of the friction disc body 1, and multiple heat dissipation holes 7 and mounting holes 8 provided on one side surface of the friction disc body 1. The heat dissipation holes 7 and the heat dissipation grooves 3 cooperate with each other to form a three-dimensional heat dissipation channel. The heat generated by friction can not only be dissipated through the heat dissipation grooves 3 on the outer surface of the wear-resistant layer 2, but also diffuse from the inside of the friction disc body 1 to the outside through the heat dissipation holes 7, further improving the heat dissipation efficiency and preventing the friction disc body 1 from failing due to overheating. The mounting holes 8 are fixedly connected to the base 9 by bolts, which can prevent the friction disc body 1 from loosening or shifting during operation, ensuring the stability of its working position, and facilitating installation, disassembly and maintenance. The outer wall of the friction disc body 1 is provided with a serrated edge groove 10, which increases the contact area between the friction disc body 1 and the air, and helps to dissipate heat. On the other hand, the serrated structure can increase the friction with other mating parts to a certain extent, improve the power transmission effect, and at the same time, it can stir the surrounding air during rotation, which helps to dissipate heat.

[0024] The positioning sleeve 6 is provided with a slot 11, and a drive shaft 12 is slidably connected to the positioning sleeve 6. A locking block 13 is fixedly connected to one end of the drive shaft 12, and the locking block 13 matches the slot 11. The drive shaft 12 is the component that transmits power, and the locking block 13 at one end matches the slot 11 of the positioning sleeve 6. The drive shaft 12 is connected to the friction disk body 1 through a sliding connection. When the drive shaft 12 rotates, the engagement of the locking block 13 and the slot 11 can drive the friction disk body 1 to rotate synchronously, thereby realizing the transmission of power. The heat dissipation grooves 3 are arranged in a radial and annular staggered pattern. This design can maximize the heat dissipation area of ​​the outer surface of the wear-resistant layer 2. When the friction disk body 1 is working, a large amount of heat generated by friction can be quickly transferred to the air through the heat dissipation grooves 3. At the same time, the staggered distribution pattern is conducive to air circulation, accelerates heat dissipation, and avoids the degradation of the material performance of the wear-resistant layer 2 due to excessively high local temperatures.

[0025] The wear-resistant layer 2 is made of reinforced nylon composite material. Nylon itself has certain wear resistance and mechanical properties. After reinforcement treatment, its wear resistance, impact resistance and other properties are further improved. It can directly withstand the friction during the working process and reduce the damage of friction to the friction disc body 1. Silicon carbide particles are added inside the wear-resistant layer 2. Silicon carbide is a material with extremely high hardness, which can significantly improve the surface hardness and wear resistance of the wear-resistant layer 2. This makes the friction disc less prone to wear and damage when it comes into contact with other parts for a long time, thereby greatly extending the service life of the friction disc.

[0026] The reinforcing layer 4 is made of fiber-reinforced nylon-based composite material. Fibers possess high strength and high modulus; when combined with nylon-based materials, they effectively enhance the overall structural strength and deformation resistance of the friction disc body 1. When the friction disc is subjected to significant pressure or impact, the reinforcing layer 4 disperses stress, preventing breakage and deformation, thus ensuring structural stability. The buffer layer 5 is made of modified nylon composite material; the modified nylon exhibits better elasticity and toughness. During operation, vibration and impact are inevitable for the friction disc body 1. The buffer layer 5 absorbs and mitigates these vibrations and impacts through its elastic deformation, reducing damage to the friction disc body 1 and related connecting components, while also lowering operating noise and improving operational stability.

[0027] Working principle: In use, the friction disc body 1 is fixedly connected to the base 9 through the mounting hole 8. Then, the locking block 13 at one end of the drive shaft 12 cooperates with the slot 11 of the center positioning sleeve 6 of the friction disc body 1 to realize the sliding connection and positioning of the drive shaft 12 and the friction disc body 1, ensuring that the two rotate coaxially. When the drive shaft 12 rotates, the locking block 13 and the slot 11 engage to drive the friction disc body 1 to rotate synchronously. During the rotation, the wear-resistant layer 2 of the friction disc body 1 contacts other mating parts and generates friction, using friction to realize the transmission of power.

[0028] During the friction process, a large amount of heat is generated. At this time, the radial and annular interlaced heat dissipation grooves 3 on the outer surface of the wear-resistant layer 2 increase the heat dissipation area and accelerate the dissipation of surface heat. The heat dissipation holes 7 on one side of the friction disk body 1 form an internal heat dissipation channel to conduct internal heat out. The serrated side grooves 10 on the outer wall also help to agitate the air and enhance the heat dissipation effect. The three work together to prevent the friction disk body 1 from overheating. At the same time, the reinforcing layer 4 improves the overall structural strength of the friction disk and resists the stress during friction and power transmission. The buffer layer 5 relieves vibration and impact through its own elasticity and ensures the stability of the friction disk body 1 during operation. Through the synergistic effect of the various structures, the functions of high wear resistance, efficient heat dissipation and stable operation are achieved.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
