With the development of science and technology, the spindle speed of the machine tool is getting higher and higher, and the speed change range is getting larger and larger. Therefore, the requirements for the stability of the bearing at high speed ar...

When the surface of the grindstone is in contact with the convex peaks of the rough raceway surface, due to the small contact area, the force per unit area is large. Part of the abrasive grains on the surface of the grindstone fell off and chipped, r...

When applying bearing preload, it is recommended to measure the deformation continuously. It should be pointed out that this deformation is nonlinear, increasing the load at the high deformation stage in the low deformation stage, and increasing the ...

The service life of any bearing depends heavily on the care and maintenance it receives. This is especially true in industrial applications, where working conditions are often harsh, heavy loads, and dust and pollution are common scales. Bearings are...

It is necessary to select the size and accuracy according to the use location, use conditions and environmental conditions, and matching the appropriate bearing is the premise to ensure the life and feasibility of the one-way bearing....

First, accurately measure the size of each defect (asymmetric type) existing in the part, calculate the small grinding amount (the amount of grinding when the size of the finished product deviates) M, and then offset the center of the part during gri...
