Bearing materials Split into the bush and the overall structure. To improve the frictional properties of the surface of the pad, often cast in one or two of its inner diameter surface antifriction material, typically referred to as the bushing, the pad so there are three bimetallic metal pads and the pad.
Integral Split Bush bearing alloy casting Bearing Materials Bushing or bearing is an important part sliding bearings, bearing and bearing liner material referred to as bearing materials. As the bush or in direct contact with the journal bearing liner, general journal section compares the wear, so the main failure mode is bearing wear. Journal bearing wear and material, bearing their own materials, lubricants and lubrication directly related to select bearing materials of these factors should be considered in order to improve the life and work performance plain bearings.
Bearing materials are: A) a metal material, such as bearing alloy, bronze, aluminum alloy, zinc-based alloy; 2) porous metal material (powder metallurgy materials); 3) non-metallic materials. Where:
Bearing alloy: bearing alloy known as white metal, mainly tin, lead, antimony or other alloy metals, due to its good wear resistant, high plasticity, running - good performance, good thermal conductivity and resistance to rubber and oil resistance and adsorption is good, it is suitable for heavy-duty, high-speed, smaller strength bearing alloys, expensive, must be cast in bronze, steel or cast iron bearing when used to form a thin coating.
The porous metal material: a porous metal material is a powder which has a porous texture, if immersed in the lubricating oil, so that the pores filled with the lubricating oil into the oil-bearing, self-lubricating properties. Small porous metal material toughness, only applies to the non-stationary and the impact load, low-speed conditions.
Bearing plastic: plastic bearings commonly have bakelite, nylon, Teflon, etc., plastic bearings have a greater compressive strength and abrasion resistance, can be used lubricating oil and water, but also self-lubricating properties, but poor thermal conductivity.
