Rated load bearing

Bearing static load, bearing in the following situations, should use the ultimate static load rating C0 stop counting: low speed, Ordinary n< 10 r / min) Slow reciprocating swing, under the effect of load for a long time rest, about (in turn Accept dynamic stress) Or bearing under stationary state, only the role of the load in a short time, also must check the peace of the related coefficient, including impact load or maximum load. Was rated static load ISO 76:1981 specification, the equivalent of the heaviest load to the center of the rolling element and raceway contact, the contact stress calculation: automatic self-aligning ball bearing for 4600 mpa all other ball bearing is 4200 mpa all roller bearings is 4000 mpa under this stress can form for deformation of the rolling element and raceway, about the scroll diameter of 0. 0001. About the radial bearing load for pure radial load; About thrust bearing, is in the center of the bearing axial load. Calculation of the bearing static load: refers to the calculation of the static load coefficient of peace, defined as: s0 = C0 / P0 type: C0 = root static load rating, KNP0 = equivalent static load, peace KNS0 = static load coefficient to calculate the equivalent static load, should be the maximum load may be present generation into the type. Bearing the basic dynamic load rating C ACTS on the dynamic load bearing under the dynamic stress, namely rotation in accept load bearing. Its expression shown to ISO 281:1990 was rated life when 1000000 revolutions of bearing the load. The size of the load and the direction is assumed constant. On the radial load is pure radial load, about the thrust bearing, is in the center of the bearing axial load. Is defined as the rolling bearing life, on one of the bearing ring or rolling body first present metal fatigue ( Peeling or fracture) Signs and the bearing can be under the revolution to a certain speed of working hours; Complete the same theory proves that the appearance of the bearing under the condition of the same work, will reach a different life.
