Bad bearing their own rigid, if insufficient mounting rigidity. Deformation and deformation of bearing mounting, caused nonuniformity of the original clearance, bearing to run rough at work, abnormal noise occurs. Especially noticeable impact of this situation on bearings, resulting in bearing many local no clearance, between roller and roller, roller conveyors and roller wear because of the crush. At the same time. Mounting isolation warping deformation results not only in the Raceway, affect the meshing clearance of ring gear and pinion and meshing performance, and the host of the quality of work, may also make the raceways and rolling elements produce edge stress and cause early failure in bearing. Bearings are fixed with bolts with a host, the mounting deformation of a rigid enough, uneven outer bolt stress under repeated, severe cases will be due to local bolt as a seriously unbalanced load, into the accident.
Usually slewing bearings under the effect of overturning moment, raceways of rolling load on general distribution by sine curve, if insufficient mounting rigidity, will change the rolling load distribution, load surge at the intersection points with the host, caused early damage of bearings. After the change of rolling load distribution. Significantly greater than the actual peak load curve 3 the loads are distributed in a sine curve.
