Solid self-lubricating bearings for grinding parts
Solid self-lubricating bearings,DU oilless dry bush mainly include JDB-1, SF-1, FB09G, and other series of bearings, which are gradually transferred to the pits on the working surface of the grinding piece by the wear-and-wear self-lubricating material in the initial stage of work; Its friction and wear performance mainly depends on the performance of solid lubricants. The self-lubricating bearing working surface materials are usually made of copper alloy, aluminum alloy--bimetal, babbitt, etc., polytetrafluoroethylene PTFE, modified polyoxymethylene, rubber, Molybdenum disulfide, black lead and the like.
The utility model can separate the moving auxiliary surface after forming a solid lubricating film on the surface of SGLXS L oilless bushing,SGLXS L shaped slide guide,oilless slide plate pad solid self-lubricating bearing, the sliding friction force can be greatly reduced, and the shaft wear is also avoided. The flying solid self-lubricating bearing and the shaft have sliding friction, and the shaft transmits torque and motion during the operation. Therefore, the hardness and strength of the shaft material are required to be high. The JDB-1 self-lubricating bearing generally adopts a metal-on-grinding part. The hardness is above HRC 40°; the SF-1 is required to be lower, and the general 45# steel can also be used. The friction and wear performance mainly depends on the performance of the solid lubricant. The solid self-lubricating bearing Outer Square bronze bushing has large bearing capacity and high rotation precision, and the solid lubricating film has anti-impact effect.
