It is no exaggeration to call a bearing a joint of a car. In a car, not only the wheels need to use bearings, but all the machine parts that will change are indispensable for the participation of the bearings. It is a very inconspicuous but very serious thing in the transmission system. Because of the large amount of work, its wear is also relatively high, so replacing the bearing is a common job in car repair. Here are a few common ways to distinguish between bearing quality: Whether the outer packaging is clear: Under normal circumstances, the factory brand has a special depiction of the external packaging, and the factory that produces the production conditions is manufactured, so the packaging is clear from the line to the color block. . Some imported brands also have a common depiction on their own packaging to protect their intellectual property, which will be continuously analyzed in the future. Whether the steel printing is clear: brand words, labels, etc. will be printed on the bearing body. The font is very clear. The fonts of counterfeit products are not only vague, because the printing skills are rough, the fonts float on the surface, and some can even be easily erased by hand. Is there any noise: hold the inner sleeve of the bearing with your left hand, and turn the outer sleeve with your right hand to make it rotate to hear if there is any noise. Because the production conditions of some counterfeit products are backward, and the hands-on operation is completely carried out, it is inevitable that impurities such as sand will be incorporated into the bearing body during the production process, so the noise will be announced during the rotation. This is the biggest difference between a factory brand that strictly enforces production specifications and operates with machines.

Bearing inspection and repair 1) Inspection and correction of the bearing housing hole The damage of the crank bearing in use is mainly wear, fatigue peeling and melting. When the engine is overhauled, new bearings must be replaced. Before repairing the bearing, first check whether the bearing housing hole meets the requirements. The roundness and cylindricity error of the bearing housing hole is not more than 0.015mm. The method of inspection and correction is: clean the bearing seat, install the bearing cap, and tighten the fixing bolt or nut according to the specified torque. When the roundness and cylindricity of the seat hole are exceeded, the welding can be welded on both ends of the bearing cap. Machining or padding adjustment, it is not allowed to repair the bearing cap. Clean the oil of the journal and bearing, cut the gap of the plastic wire into the same length as the bearing width, and place it on the crank pin so that it is parallel to the center line of the shaft. Carefully install the bearing cap and set the nut according to the regulations. Torque tightening, carefully remove the bearing cap, use the measuring tape printed on the plastic line gap gauge bag, measure the width of the widest part of the flattened plastic wire, and obtain the gap value. Replace the new bearing when the limit value is exceeded. 2) Matching of bearings At present, the commonly used bearing alloys for gasoline engine crankshaft bearings are babbitt and high-tin aluminum alloy. The thickness of the alloy layer is 0.30~0.35mm. In addition to the standard size, the bearing size is reduced by 0.25mm according to the inner diameter. The primary repair size corresponds to the crankshaft journal for use in repairs.

A bearing that is subjected to a sliding motion by a shaft and a bearing is called a sliding bearing. According to the principle of oil film formation on the two opposite moving surfaces of the sliding bearing. Can be divided into fluid dynamic pressure lubrication bearings (also known as dynamic pressure bearings) and hydrostatic bearings (also known as hydrostatic bearings). Generally discussed is a hydrodynamically lubricated bearing that carries oil between two surfaces by relative movement of the shaft and the bearing to form a sufficient pressure film to separate the two surfaces to withstand the load. Commonly used bearing materials are divided into metal materials and non-metal materials. (1) Cast iron. Ordinary gray cast iron or wear-resistant gray cast iron with nickel, chromium and titanium alloy composition, or ductile iron can be used as a material for light-load low-speed bearing bushes. In these materials, a sheet-like or spheroidal graphite component is coated on the surface of the material to form a layer of lubricating graphite. After the surface of the wear-resistant cast iron is phosphating, a porous thin layer can be formed, which helps to improve the wear resistance. (2) Bearing alloy. (usually babbitt or white alloy) bearing alloys are divided into two categories: one is based on tin, adding appropriate amount of bismuth and copper, called tin-based bearing alloys, such as ZChSnSb11-6; the other is Lead is the basic component, and an appropriate amount of tin and antimony is added, which is called a lead-based bearing alloy such as ZCnPbSn16-16. (3) Copper alloy. Copper alloys can be divided into: cast lead
