The precision of spherical roller bearing and surface finish

Bearing - Comfortable and durable - Electricity department authors explain for you: on July 15, precision and surface finish of spherical roller bearing, if the shaft or the precision of the shell is not in conformity with the requirements specifications, the performance of the bearing will be affected, they do not provide their full ability. Square degrees of spherical roller bearing, for example, may lead to inaccurate shoulder bearing internal misalignment and outer ring, which may reduce the edge of the bearing fatigue by adding in addition to the normal load live load. Occasional cage bone fracture and attack for the same reason that the shell should be rigid provide strong support. High rigid shell from his perspective is also good, load distribution for normal operating conditions, such as rotating completed or smooth non-porous finish to make parts surface is smooth; For applications, however, must be polished processing vibration and noise must be low or heavy load application. Under the condition of the installation of two or more bearing a single shell, shell parts surface hole should be designed for the two bearing seat can complete such as with an operation. In the case of split type shell, installed in manufacturing houses have to be careful when the outer ring will not deformation. Shaft precision and surface roughness under normal circumstances, lists the operating conditions. Self-aligning roller bearing precision and surface finish, size of fillet shaft contact or shell, the surface of the bearing must be perpendicular to the axis of the centerline. Front for tapered roller bearing shell side shoulder hole should be parallel to the bearing in order to avoid interference with cages. Spherical roller shaft and the shell of the rounded corners should not go into contact with the bearing chamfer; Radius r a, therefore, must be less than the minimum bearing chamfer size r or r 1. Two shaft and the shell's shoulder high radial bearing should be sufficient to provide good results support the surface of the bearing, but should be extended to the shoulder enough to allow for use special removal tools recommended metric the smallest shoulder height of the radial bearing. Bearing installation related nominal size column in carrying the table, including the right shoulder diameter. Enough is particularly important at the highest point of the shoulders is support side rib taper roller bearings and cylindrical roller bearings under high axial load. Should be used in table figure h and r value in these cases, a shaft of radius or shell, and values are often used in the undercut grinding of the shaft of the fillet radius.
