Problems solved by technology

At present, many bearing materials have serious wear on the friction pair, the limit PV value is low, the self-lubricating effect is not good, and it is difficult to achieve dry start
Traditional non-metallic materials need to be lubricated or soaked in lubricating medium in advance, and can only be started after sufficient lubrication. On the one hand, a complex lubrication system is added, and on the other hand, the instability of the lubrication system directly leads to lubrication failure, causing the bearing to burn. Therefore, its application range restricted

Abstract

The invention discloses a sliding bearing material of elastoplastic polymer alloy, comprising the raw materials of the following mass portions: 100-120 portions of prepolymer resin, 20-45 portions of crosslinking curing agent, 1-6 portions of antiwear agent, 2-17 portions of lubricating agent, 0.1-1 portion of defoamer and 0-0.5 portion of pressure additive. The material has the characteristics of wear resistance, impact resistance and high limit PV value, and suitably used as a nonmetallic bearing material for water or self lubricating.

Description

technical field [0001] The invention relates to an elastic-plastic polymer alloy sliding bearing material. Background technique [0002] Bearings are used to determine the relative movement position of the rotating shaft and other parts, and play a supporting or guiding role. During the working process of the bearing, its radial direction bears long-term load and high friction, so the bearing is prone to creep, and even fatigue damage or wear failure, resulting in the need for continuous replacement of the bearing. [0003] Ideal non-metallic bearing materials have very high requirements on the tribological properties of materials such as wear resistance, self-lubrication, and limit PV value. At present, many bearing materials have serious wear on the friction pair, the limit PV value is low, the self-lubricating effect is not good, and it is difficult to achieve dry start. Traditional non-metallic materials need to be lubricated or soaked in lubricating medium in advance,...
