Introduces a motor dedicated page and bearing heating causes and function parameters

Editrice motor special beauty bud and bearing heating and function parameters of motor bearings NMB fever reasons: 1. Is in need of lubrication oil problem: NMB bearing, lubricating oil quality and bearing running quality, the relationship between the bearing life is very big. Running resistance such as quality, grease, grease will not adsorption in the rolling element or roll road, no lubrication bearing, friction force increases, the heat increased, the bearing will be fever; Not too thin, high speed of the roller will soon put grease extrusion or left out, the same fever. There are oil metamorphism, pollution can also cause bearing heating. 2. Inappropriate environment: inappropriate environment is easy to cause the bearing temperature rise, such as housing, integrating ash can affect bearing cooling; Environmental temperature on the high side also can make bearing heating, such as the summer sun point-blank, or motor with electric heating device to heat radiation; And ventilation is bad, difficult to convection, can make the heat dissipation of the motor is affected, these can make motor bearing temperature, etc. NMB bearing function parameters: 1, the cage and material: J steel plate stamping 2, the number of columns: roller single row 3, roller type: spherical roller, weight: 0. 002 ( kg） 5, bearing material: high carbon chromium bearing steel, precision grade 6: P07, rolling element: the ball 8, groove type: deep groove raceway, sealing cover: double sealed, purpose: gm
