HRB bearing small make up to introduce bearing wear and tear

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Bearing wear and tear of the specific reason mainly has the following kinds: the friction on the surface of small peak valley squeeze each other, gradually fall off the surface layers of brittleness and wear. (1) the oxidation wear and tear. Bearing tiny peak valley of relative motion appearance and oxidation synthesis and in the air and substrate metal joint fragile brittle oxide, the oxide off in the friction, wear called oxidation wear. (2) thermal wear friction. When bearing in high speed under the condition of heavy load and poor lubrication, appearance in the peak valley due to friction decreased hardness and wear resistance high temperature, contact, adhesion and tear occur even. The wear and tear, called friction heat and wear. (3) hard wear. If bearings make relative movement, organization uneven bearing movement appearance, the presence of hard particles, or between the movement appearance of bearing fall into impurities such as grains of sand, chip, chip, bearing in relative motion, hard or impurities can make the bearing surface scratch groove, even the wear and tear, called hard wear. (4) spot corrosion wear. Gears, bearings and rolling contact surface, the relative process periodically by a lot of contact pressure, long effect, metal fatigue phenomenon appearance, makes the bearing tiny crack and erosion on the surface, the wear is called pitting wear. Due to rust or corrosion, chemical corrosion effect caused by the wear and tear. Bearing appearance of acid, alkali, salt liquid or the erosion of harmful gases. To speed up the wear process, the wear called chemical corrosion effect caused by the wear and tear. The microstructure of the metal or chemical composition change, lower the bearing surface wear resistance, hardness, speed up the wear process. The wear and tear, called high temperature effect caused by the wear and tear. Due to water, acid, alkali, salt, liquid and harmful gas such as temporary contact corrosion damage: the movement of the bearing on equipment. Due to rust or corrosion and damage, known as corrosion damage.
