Description

TECHNICAL FIELD

[0001] The utility model belongs to bearing technical field, and particularly relates to a high-strength bearing of impact load resistance. BACKGROUND

[0002] Most bearing designs do not fully consider the impact of extreme impact load, resulting in cracks or plastic deformation of the inner and outer rings and balls when encountering sudden load, thereby reducing its performance. The main reason for these shortcomings is the limitation of material selection and structural design, and many bearings use materials that lack sufficient toughness and strength when facing instantaneous impact.

[0003] The conventional approach includes using higher strength materials and optimizing the structural design of the bearing, for example, introducing higher bearing outer ring thickness or increasing the diameter of the rolling body to enhance the impact resistance. However, the disadvantage of these methods is that although the impact resistance of the bearing is enhanced, the weight and cost of the bearing are also increased, and it may cause larger space occupation. In addition, the change of material or improvement of design may not be compatible with other components in some applications, thereby affecting the overall performance of the machine, therefore, we hope to design a bearing with a new structure to solve this problem.
