The INA miniature bearing vibration fault approach

INA bearings technology determine the maintenance cycle of machinery and parts in the process of using the technology of state will gradually degenerate, leading to decline in reliability, ability to work some or all of the loss. In order to make the machine keep good technical performance and high reliability level, you need to set up perfect reliability management or control system. In practice, the realization of functions, there are two ways of reliability of control system. The first way above, through the perfect miniature bearing technology maintenance system performance: to maintain the machinery in the second way is by scientific maintenance system to restore the machine's technical capabilities. 1, the characterization of INA bearings vibration quantity has three kinds of vibration displacement, vibration velocity and vibration acceleration. 2, determined by bearing structure design parameters of stiffness, flexibility, quality, and damping of vibration system under the condition of operation will produce that can meet the needs of its mechanical vibration. 3, manufacturing processes of the deviation caused by vibration, the smaller the deviation, the less vibration. 4, operating conditions: installation condition, speed, direction and magnitude of axial load. The influence factors of miniature bearing vibration: 1, roundness, waviness and surface roughness on the surface of the steel ball is the most profound effect on the vibration of bearing parts factors; 2, followed by the shape of the inner ring and outer ring channel error and surface roughness; 3, again is bearing cleanliness and lubricant quality, etc. INA bearings is the purpose of technical maintenance to prevent machinery and parts arrive early critical state, or delay time of arrival in critical state. Therefore, can be prevented by detecting the keep mechanical performance parameters within the rated, so as to prevent the occurrence of failure: or by slowing down technical parameters change process and reduces friction element to damage and prolong the mechanical work and life.
