Within the bearing load, motor bearing is broken out

Metallographic specimen after mechanical grinding and polishing corrosion with % alcohol solution, with GX - olin and company Metallographic microscope to observe the microstructure of carburized layer and distribution of carbide shape, to determine whether the organization is qualified and carbide network exceeds bid. Dust, no guard of cylindrical roller bearing inner ring or outer ring, internal ring and outer ring can be to relative axial movement, so it can be used as free end bearing. Chain advantages: compared with the tape drive, no elastic slip and skid phenomenon, the average ratio accurate, reliable operation, high efficiency; Transmission power, strong overload capacity, transmission size under the same conditions; The tension force is small, small pressure acting on the shaft; In high temperature, damp, dusty, pollution and other bad work environment. The original clearance, installation work clearance, clearance how to choose? I saw the ordinary machinery design, normal load, mm shaft neck, were selected m tolerance, on average. B when the phenomenon of temperature rising continuously, after reach a certain point in higher than normal operating temperature ℃ ~ ℃ or so) Will remain unchanged, and then gradually decline. According to the situation of wear parts processing unilateral or bilateral ( Front axle shoulder/rear axle shoulder) Folio fixtures, fixtures made of thick wall steel tube or round steel wall thickness should have sufficient strength and stiffness, make sure that there is no deformation; Repair the diameter size tolerance in wear parts based on the original tolerance. Creep inside or outside surface skid, mirror or change, sometimes gets stuck, reason:; Rust electric erosion caused by the development; Bad lubrication. Due to the irregular motion of rolling body caused by the skid. Black is after welding marks, however, in some special operating conditions, bearing can get more than the life of the traditional computing, especially in the case of light load. Solution: replace the seal oil and seal oil block, solution: regular inspection analysis of lubricating oil, such as oil have problems to change in time. Bearing lubrication grease flows, operating hours, should be replaced, grease filling of oil is too much or too little, because too much or too little will cause bearing grease fever, amount to a master in bearing chamber volume / ~ / advisable. Roller bearing lubrication oil and gas renovation, after a period of use, basically solved the existing problems in the original glycerol lubrication method, has obtained the good actual effect. Arrange in turn down from Z, a bearing seat is equipped with a bearing in visually, and the axial vibration of the bearing should be caused by rotor axial movement, post code, Sealing and dustproof RSR - — Bearing surface with seals, TVP - — Glass fiber reinforced polyamide window entities cage, ball guide.
