LLFig. 1 Fig. 2 Back-to-back arrangementsFig. 3 Face-to-face arrangementsThere may be some applications where the bearing arrangement needs to be preloaded requires a negative operating clear-ance. In applications such as machine tool spindles, automotive differentials and elec-tric motors, preload enhances stiffness or precise shaft positioning. Preload can be obtained with a spring or by adjustment ( by a nut). Springs are also used to provide a minimum load on lightly loaded is typically expressed as a force, but can also be expressed as a distance (path).
A pinion arrangement design (igs. 6 and 7, page 6) typically consists of two different size tapered roller bearings, A and B, with diff erent spring constants c A and cB. Both are subjected to a preload force F 0. If an external axial force K a acts on bearing A, bearing B becomes un loaded, and the addi - tional load acting on bearing A ...
