Bearing load and failure modes

Bearing load and failure forms of bearing is an important part of the machine, its moment changes in relationship to the mechanical equipment operation problem, now the author say about the change of the loading and failure mode of the rolling bearing characteristics. (1) for rotation circle and rolling body after carrying the contact load and stress at each point is changing; And in every contact point of the contact load and the characteristics of the stress pulse cycle; In the bearing area is not affected by load; Fixed ring 2 for each point of the load and stress is unequal, and at each load point load at the time of the contact load and stress have rendered the same pulse cycle characteristics, just with different values of amplitude; One of the most bottom loading its value is the largest, for deep groove ball bearings, 6 class) :F0 = ( 4. 37 / Z) Fr。 Rolling bearing failure modes (1) for the normal operation of bearing, 10 r / min < n < nlim) — — Inside and outside the circle and rolling body fatigue pitting; For static don't turn or low speed ([2] n≤10 r/min） Or intermittent oscillating bearing - — Inside and outside the circle and the plastic deformation of roller; (3) inside and outside the circle and the inevitable friction and wear of rolling body; The design of the rolling bearing criterion (1) for the normal operation of the bearing - — To prevent fatigue pitting corrosion, based on fatigue strength calculation, life calculation; 2 for low-speed bearing, or continuous under load or discontinuity under load and not rotating bearing, control plastic deformation, demand -- — Static strength calculation; (3) for high speed bearing - — In addition to life calculation, and calculation of the bearing limit speed.
