Bearings are the most basic parts of machinery. In the general mechanical design, according to demand, adopt standards and manuals. But with the mechanical manufacturing technology progress, and the improving of performance, in many occasions in the design only take into account such a level has been unable to meet the requirements.
In the usual mechanical design should pay attention to the deep bearing application design, in order to obtain the best design results:
1.The geometrical accuracy requirements for the bearing-related parts are matched to the bearing's accuracy grade. At present in many common mechanical parts there is this problem. We generally known that the bearing ring for the thin-walled parts, with the shaft, hole size accuracy or position accuracy is not good, will directly affect the bearing deformation or force state, directly lead to assembly after the movement performance.
2.Bearing the improper use of the problem is not much, we can master. But the characteristics of the selected bearing, and thus how to optimize the design of the assembly of the size of the assembly chain, is not to ignore the details, if not properly, will inevitably reduce the bearing life. Such as clearance adjustment, positioning structure, preload and other details can not be ignored or omitted. Some of which are bound to be adjusted according to mechanical performance requirements, different factors in different hosts or different occasions should be different, which requires our designers based on the standard technical parameters provided by the bearing, in-depth study and make Different designs, and even constantly sum up and optimize the design of this detail.
In short, in the mechanical movement, the bearing is a basic piece, but also the most concentrated mechanical failure parts, there is a depth of our application design optimization space, to be more in-depth discussion.
