The shaft and the bearing direct contact with the prevent the occurrence of adhesion and the formation of the boundary lubrication performance. Compatibility of materials of the impact of Friction factors are:
(1) as vice Materials and Metallurgy, constitute the degree of difficulty of the alloy.
(2) the the affinity and capacity of the materials and lubricants.
(3) into a pair materials state without lubrication, the friction factor.
(4) The microstructure of of the material.
(5) the thermal conductivity.
(6) the size of the surface oxide, film characteristics.
2 the clamp into the sex
Materials, external hard particles clamp allows the lubricant into to prevent scratches or (and) the ability of the abrasive wear. Metal materials, the low hardness and elastic modulus of the lower clamp into like, non-metallic materials are not necessarily, such as carbon graphite, lower modulus of elasticity, but the clamp into the bad. Spherical roller bearings are usually relatively soft material and hard material composition friction pieces, generally with soft materials bearing.
3. The Run
In the shaft and the bearing run-in process, reducing the shaft diameter and bearing machining error, concentricity error, the surface roughness parameter values ??to make uniform contact, thereby reducing the ability of the friction and wear rate.
4 various friction compliance
Materials rely on the surface of the elastic-plastic deformation compensation, the sliding friction surface of the initial with the bad and the axis of the flexural properties. Low modulus of elasticity of the material compliance.
5 abrasion resistance
Into the capacity of Vice materials to resist wear and tear. Under the provisions of wear and tear conditions, the wear rate or wear degree of wear of the reciprocal of the wear resistance.
6 fatigue resistance
Material resistance to fatigue failure under cyclic loading. In the temperature of the bearing strength of the material, hardness, impact strength and even fight fatigue is very important. Run, the clamp into the good material, usually poor fatigue resistance.
7 corrosion resistance
Material to resist corrosion. Lubricants used in the atmosphere will gradually oxidized, acidic substances, and in most lubricants containing extreme pressure additives, they are corrosion FAG bearing materials, self-aligning roller bearing material with corrosion resistance.
8 the gas corrosion
Solid state for the liquid movement, when the bubbles in the liquid near the solid surface rupture, the local impact of high pressure or localized high temperatures will lead to cavitation wear. Materials ability to resist cavitation wear is called the resistance to cavitation. Typically, gas corrosion resistance of the copper-lead alloy, tin-based FAG self-aligning roller bearing alloy and aluminum zinc silicon type alloy.
9 Compressive strength.
Withstand the one-way load and not pushed the bad or size does not change the ability.
