SKF bearings support structure design of axis of motion accuracy and performance played an important role in the work of the bearing, require comprehensive consideration of bearing arrangement, qualified and adjustment of axial position, compensation of thermal expansion of the shaft, bearing clearance adjustment, fastening, lubrication of bearings and seals, and so on.
(1) the arrangement of bearings
General dual hinge support structure, made up of each of the supporting shaft with 1~2. Under purely radial load of shaft, two supporting symmetric arrangement of NSK bearings can be taken. Combined effect of radial load axial load axis, two bearing angular contact ball bearings often use the same model, in which case the two bearing arrangement are arranged back to back, face to face and in-line three ways.
(2) the support structure of the basic types
Radial location of FAG bearings typically have two supporting mutual qualified, and axial position qualify there are a variety of ways, can generally be divided into both ends of fixed supports, fixed-bearing on both sides and walks-walks supports three basic forms.
