Linear sliding bearings functioning of different sound and eliminate impact on life

There could be many factors affecting the service life of linear sliding bearings use may result in the factor and the internal friction has been further instructions. Used to adjust the main factor is the installation, use and maintenance, maintenance, such as conform to technical requirements. According to the needle roller bearing installation, use, maintenance, maintenance of the technical requirements of the bearing contact load operation, speed, lubrication condition monitoring and inspection, found that the immediate cause of abnormal adjust back to normal. Installation conditions for needle roller bearing is one of the factors is often caused by incorrect installation package state changes between the parts of bearing force, the primary factor of the abnormal state of linear sliding bearing operating temperature, vibration, noise, and improve the quality of raw materials. The proportion of raw materials quality factors in the analysis of the bearing is markedly reduced, but it is still one of the main factors of bearing failure. Choose whether or not is still appropriate linear sliding bearing failure analysis must be considered. Needle roller bearing manufacturing will through forging, heat treatment, cutting, lubrication condition, to monitor and check the proximate cause of the abnormal findings to adjust back to normal. Installation conditions is one of the factors of using bearing is often caused by incorrect installation package state changes between each part of the primary factors of bearing capacity in the abnormal operation status, and early termination of the main factors of inner life, refers to the structure design, high quality manufacturing process and material, there are three factors determine the quality of the bearing. Phenomenon: 1) The engine idle speed has no obvious noise during operation, and high speed in the thrum 'giggle' ( ) emitted from crankcase 2) Hurry go after loosening the gas instantaneous sound more obvious. 3) No obvious change after the temperature rise. When the load increases, the sound is growing. 4) Sound is linear sliding bearing ring slow, short. Reasons: 1) Bearing and shaft neck wear too much, the radial clearance is too large. 2) The bolt bearing cover is loose. 3) Bearing alloy ablation or fall off. 4) Journal circles. 5) Bearing and the bearing relative rotation. Diagnosis: 1) Engine speed by the idle speed to medium speed when excessive noise is clear, with higher speed, the noise is more outstanding, for high temperature bearing ring. 2) Fire test of a cylinder is carried out, the sound diminished or disappeared, for the cylinder bearing ring. 3) No matter what speed and temperature are sound and engine vibration, do fire test sound doesn't change, is the high temperature alloy bearing ablation.
