Distinction between high and low speed operation of bearing

Bearing is an indispensable part of many mechanical parts, the performance of the bearing will directly affect the mechanical performance, so many people in the purchase of mechanical equipment will also pay attention to the performance of the bearing, among them, the high and low speed operation of the bearing plays a decisive role in the use of the bearing, China bearing website decomposes the high and low speed operation of the bearing.

   according to the speed, it can be divided into two kinds of high-speed bearings and low-speed bearings, and these bearings occupy a very important position in our present industrial field, and even drive the development of an industry. We usually drive cars, and all kinds of electrical facilities in our home have bearings.

What is the difference between high speed and low speed bearings? Many friends may have misunderstandings about him. It's not that the rotation speed of the bearing itself is different, but the internal structure of the bearing is different. The bearing belongs to high speed or low speed, which is divided by its linear speed. Many low-speed bearings can rotate tens of thousands per minute, while some high-speed bearings only rotate a few hundred per minute. In addition to their name and their linear speed, there is another difference that the rotating parts in their structure are also different. Generally speaking, the rotating parts of low-speed bearings are circular, some are cylindrical or even conical, while the rotating parts of high-speed bearings are mainly bearing shells.

   at the same time, from the appearance, there are some differences between the two. Generally speaking, the appearance of low-speed bearing is rougher, and the joint between parts is looser. In order to ensure its accuracy and precision, the surface of high-speed bearing is generally very smooth, and the distance between inner ring and outer ring is very small, And it's a lot more accurate.

   another point is that there are some differences between high-speed and low-speed bearings in materials. High speed bearings generally use very high hardness steel, which can withstand the pressure brought by too high rotating speed. Ordinary bearings, if the speed is relatively low, use some ordinary materials and do not need to bear too much pressure, Therefore, the hardness and durability requirements of materials are also relatively reduced.

   in fact, both low-speed and high-speed bearings are manufactured after precise design and repeated inspection by designers. Although its parts are very small, its technological innovation and change can often drive the development of an industry, and its role can not be underestimated. Therefore, if our daily equipment contains bearing parts, we must pay attention not to damage it, otherwise it may cost a lot of maintenance costs.
