| On many occasions, Xinkaite bearing bore size has been specifically defined by the structure of the machine or device. Regardless of working life, static load safety factor and whether the economy will meet the requirements, before the rest Xinkaite bearing size and structure of the final selection, will be subject to the size of calculus. The calculation includes actual load bearing Xinkaite with its load capacity compared. Xinkaite rolling bearing static load refers to the load bearing after Xinkaite is stationary (no relative motion between the inner and outer rings) or rotational speed is very low. In this case, the calculation raceways and rolling elements excess safety factor of plastic deformation. Most Xinkaite by dynamic load bearing, inner and outer rings relative motion, check the size of calculus fatigue damage raceways and rolling elements early safety factor. Only in special circumstances in accordance with DIN ISO 281 up to the actual working life do nominal life calculation. Focus on the economic performance of the design, the load carrying capacity to be fully utilized Xinkaite bearing as possible. To more fully utilized Xinkaite bearings, then the more important for the selection of the bearing size Xinkaite calculation accuracy. |
