Steam turbine bearings, thrust bearings bearing and deep groove ball bearings

Applications: low speed, light load or intermittent work machine, according to the material classification list: strength enough material can be directly into bearing, such as brass, gray cast iron. After choose the right tools, can the bearing installed, when installation should pay attention to have no bruising, rust layer, abrasive dust, sand, dust and dirt, can cause installation if any difficulty, must keep the imported bearing surface and cooperate with the assembly parts surface clean. Its reason because of its characteristics of good wear resistant, high plasticity, saturation performance is good, good thermal conductivity and good bonding resistance and oil adsorption is good, but, because of its price is more expensive, so, when use, must be casting in bronze, steel or cast iron shell and form a thin coating. A case, the fracture source is located in the surface of the parts or the surface or in the stress concentration at the initiation, such as Angle, holes, grooves and surface damage, such as weak links. Life ( Refers to the set of bearing) Life of a bearing ring or a washer or a rolling element material fatigue before expansion appeared for the first time, a ring or a washer relative to the other a ring or a washer of the revolution. A double LieDiao roller bearing users reflect a set of oversize bearings bearings bearings in use process found their to appear early failure, the set of bearing ring is used for cement grinding roller, poor working conditions. Parameters, moreover must also consider other parts to optimize system performance, do not follow the installation and maintenance requirements will result in equipment failure, constitute a major security hidden danger, of course not bearing clearance is too large, thrust bearing installed correctly, the seat can automatically adapt to roller rolling, to ensure that the rolling element is located in the top and bottom ring raceway. Diving deep well pump, where the improvement is as follows: skeleton oil seal modified single mechanical seal, the purpose is to prevent the motor chamber water and other debris into the bearing, speed bearing wear failure; Bearing cavity filled with oil, the purpose is lubricated bearing, lubrication and cooling mechanical seal, improve bearing under working environment. Bearing seal failure, leading to the external bearing inner dirt or moisture, cause bearing corrosion, clean the bearing of removed, advanced coarse fine clean after cleaning. Can use high temperature austenitizing ℃, or ℃ high temperature, also can use forged heat to achieve rapid annealing process, for GCr steel after quenching, demanding the average carbon content is. With the method of inspection, cleaning the bearing shell, first check the bearings should be no crack, sand holes, the phenomenon such as shell, and then on the shaft neck evenly coating thin red lead, don't apply it too thick, it will effect the inspection. Scheme and size size series, radial ( The axial) Radial distances ( 轴向) distan - Methyl amino acetonitrile ce in radial ( The axial) Measure the distance.
