Understand ina rolling bearing load degree to prevent injury

1, bearing radial load first accept ina bearings for centripetal bearing radial load. This type of bearing the nominal contact Angle of a0 & gt; = 450. Communication to the size of the roller bearing is larger than of radial load ball bearing can accept. N and NU type cylindrical roller bearing can only accept the radial load, other types of centripetal bearing radial load is acceptable, also can accept the axial load. 2, bearing the axial load of the primary accept axial load of the popular for thrust bearing, ina bearing its nominal contact corner a0 & gt; 450. Thrust bearing and thrust angular contact ball bearing according to the structural differences can also accept one or two tendencies of axial force. Under the radial load, ina bearings will produce effects on the axial force, typically by the second bearing. Two single row angular contact ball bearing or bearing configuration of tapered roller bearings back to back or face to face, each bearing must inherit from another bearing axial force. Two bearing phase at the same time, the radial load at the centre of the two bearings, if bearing configuration adjusting zero clearance, half part load bearing load distribution can be automatically achieved. Should keep in mind that not only affected by the bearing elastic rigidity, and shaft and the installation of the elastic bearing, ina bearing ring cooperate and all other components in the stress field, including the influence of the elastic deformation of bearing. All of these factors on the axis of the whole system of elasticity has considerable influence.
