Check the check manual, found strange, deep groove ball bearing dynamic load and static load is large, much largerBut the dynamic load of spherical roller bearing is much smaller than that of static load. The tall man knows, tell me to solve the puzzle!
Rated dynamic load refers to the rated life of 1 million RPM bearings bear the load,Rated static load refers to the bearing load, the static load of the largest roller and raceway contact, permanent deformation and rolling body raceway and rolling body for the diameter of the 1/10000. Know the definition, your problem is not a problem.
Deep groove ball bearing dynamic load static load dynamic load: the reason is often in the static load on certain safety factor after that, considering the motion of the impact load so deep groove ball bearing dynamic load static load.Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient (friction, coefficient) during movement, and guarantee its rotary accuracy (accuracy). According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher. Generally, the rolling bearings are composed of four parts, namely, outer ring, inner ring, roller and cage. Strictly speaking, the rolling bearings are composed of six big parts, namely, outer ring, inner ring, rolling body, cage, seal and lubricating oil. Mainly with the outer ring, inner ring, rolling body can be defined as rolling bearings. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.Load refers to various applied in engineering structure on the engineering structure or component effect of the direct effect of habits, common are: the weight of the structure, floor live load and live load on the roof, roof ash load, vehicle load, crane load, equipment load and wind power, snow and ice and wave loads.
You look at the rated dynamic load and rated static load calculation methods and principles, it is estimated that you can easily solve the problem. If you don't understand, I suggest you look at the design of rolling bearing Changsen million "". Jia Qunyi's "rolling bearing design and application" of these two domestic bearings design classic monographs.
