How to distinguish high-speed spindle bearings from low-speed bearings-

Bearings are an indispensable part of many mechanical parts. The functional application of bearings will affect the performance of spindle equipment. Therefore, many people also care about the performance of bearings when purchasing spindle equipment. Among them, the high and low speed of bearings Operation plays a decisive role in the application of bearings, so this article will explain how to distinguish high-speed spindle bearings from low-speed spindle bearings. Many good friends may misunderstand him. It is not that the speed of the bearing itself is unusual, but the structure of the internal structure of the bearing is different. The bearing is classified as fast or low gear by its angular velocity. The speed of many low-speed gear bearings can reach tens of thousands of revolutions per minute, but some high-speed spindle bearings only have a few hundred revolutions per minute. In addition to their naming and their angular velocity, there is another difference that the parts used for rotation in their structures are different. Generally speaking, the rotating part of the low-speed gear bearing is elliptical. Some are cylindrical or even tapered, while the part that rotates in high-speed spindle bearings is primarily the bearing pad. There are some differences between the two types of bearings in terms of appearance. Generally speaking, the surface of low-speed bearings is more rough, and the joints between parts are more loose. In order to ensure its accuracy, high-speed spindle bearings And other high-precision levels are generally very smooth on the surface, while the distance between the inner hole and the outer side is not large, and other precision levels will be much higher. Another point is that on the material, there is a slight difference between high-speed and slow-speed bearings. High-speed spindle bearings generally use very high-strength stainless steel plates, which can withstand the pressure generated by excessively high speeds for parts. If the speed of ordinary bearings is relatively low, some ordinary materials are basically used, and they do not need to bear a lot of pressure, so the requirements for the strength and durability of materials are correspondingly reduced a lot. Whether it is low-speed gear or high-speed spindle bearings, they are actually produced after repeated designs and continuous testing. Although its parts are very small, its technological innovation and changes can often promote the development of an industry, and its role cannot be underestimated. Only when the torque is accurate can the rotation be stable! (/rhqfgs.html)
