Steel ball factors, which affect the bearing performance

1) ball mill wear-resistant steel ball shape error influence on bearing performance of the wear-resistant steel ball mill shape error is one of the important reasons affecting bearing vibration and noise. The vibration of the form error, the greater the bearing. Bearing rotates, as a result of the existence of ball mill wear-resistant steel ball shape error, cause changes in the ball mill wear-resistant steel ball center continuously thus caused the bearing of the low-frequency vibration and noise.
(2) the ball mill wear-resistant steel ball surface roughness affects the performance of the bearing surface roughness refers to the ball mill of wear-resistant steel ball for ball mill wear-resistant steel ball surface in addition to the spherical error surface micro-roughness and waviness. Ball mill in wear-resistant steel ball surface roughness of bearing, the high-frequency vibration has a great impact, make the bearing produces noise. Ball mill wear-resistant steel ball surface roughness of bearing vibration is greater than the influence of surface of ring channel, its value, the greater the bearing vibration is the higher. Therefore must be strict control of the wear-resistant steel ball mill table surface roughness.
(3) ball mill wear-resistant steel ball surface defects affect the performance of the bearing surface defect of wear-resistant steel ball for ball mill is caused by mechanical processing, rust corrosion or raw materials mill wear-resistant steel ball surface crack, scratch, rust, and depression. As a result of the ball mill, wear-resistant steel ball surface defects will cause the pulse type vibration of shaft bearing, rotate the bearing vibration, and noise, so the ball mill wear-resistant steel ball surface defects are not allowed. The pulse cycle is inversely proportional to the bearing rotating speed, the size of the vibration, and the size of the defect. Pass the test now, ball mill wear-resistant steel ball surface defects, the greater the bearing vibration value is higher. Large ball mill in the steel ball, lining board, the impact of the material between serious, of the ball mill is the loss of metal carbide micro-breakout caused by abrasion as the main body. For the average diameter of steel ball mill, material cutting with ball mill steel ball surface between as the area of the claw is relatively small, so the wear of the cutting metal loss in a secondary position.
Generally speaking, in the medium and small ball mill, cutting wear and fatigue spalling is a major cause of the loss of metal ball mill ball, can choose high hardness martensite steel ball mill. Ball mill ball in the heat treatment process after stabilizing treatment, secondary carbides are dispersed in the tissue of the martensite, can reduce the cutting wear and tear caused by the loss of metal.
