Abstract and Keywords

Abstract: The friction and wear performance of the brake belt of washing machine has an important impact on the smooth braking of washing machine, so it is necessary to study the friction and wear performance of the brake belt of washing machine under different friction conditions. In this paper, through the friction and wear test of the end face of the brake belt of washing machine under the condition of surface contact, the influence of different friction conditions such as sliding speed and brake pressure on the friction and wear performance of the brake belt material of washing machine is analyzed, and the friction and wear mechanism of the brake belt of washing machine is discussed. The results show that higher or lower speed and load will cause a decline in the friction performance of brake materials, which is not conducive to brake friction. The increase in speed and load will lead to an increase in wear of brake materials, and the higher the speed and load, the more intense the increase in wear. The friction stability and wear resistance of brake materials are the best at 160 N and 400 r/min. The wear mechanism shows that the micro convex body on the contact surface is compressed and deformed under the action of friction to fill between the substrate surfaces, forming a smooth and flat surface, thereby stabilizing the friction coefficient and improving the wear resistance.

摘要和关键词

摘要: 洗衣机制动带的摩擦磨损性能对洗衣机的平稳制动具有重要影响,因此有必要研究不同摩擦条件下洗衣机制动带的摩擦磨损性能。文章通过开展洗衣机制动带在面接触条件下的端面摩擦磨损试验研究,分析不同滑动速度和制动压力等摩擦条件对洗衣机制动带材料摩擦磨损性能的影响,探讨洗衣机制动带的摩擦磨损机理。试验结果表明:较高或较低的速度和载荷会造成制动材料的摩擦摩阻性能下降,不利于制动摩擦;速度和载荷的增加会导致制动材料磨损量的增加,且载荷和速度越高磨损量增加得越剧烈;在160 N、400 r/min下制动材料的摩擦稳定性和抗磨损性能最佳。磨损机理表明,接触表面的微凸体在摩擦力的作用下受压变形填充到基体表面之间,形成光滑平整的表面,从而有助于稳定摩擦系数并提高耐磨损性能。
