Bearing combined configuration manufactured by magnetic steel alloy, iron silicon alloy, nickel-based alloy and martensitic stainless steel

Abstract

The invention discloses bearing combined configuration manufactured by magnetic steel alloy, iron silicon alloy, nickel-based alloy and martensitic stainless steel. The bearing combined configurationmanufactured by the magnetic steel alloy, the iron silicon alloy, the nickel-based alloy and the martensitic stainless steel is manufactured by the magnetic steel alloy, the iron silicon alloy, the nickel-based alloy and the martensitic stainless steel. The bearing combined configuration manufactured by the magnetic steel alloy, the iron silicon alloy, the nickel-based alloy and the martensitic stainless steel also comprises an alloy bushing; and the alloy bushing adopts easy-to-deform materials such as aluminum, lead, tin, copper or alloy thereof. The alloy bushing is a cylindrical bushing with a blind hole. The combined piece obviously reduces the destructive effect of electrochemical corrosion; and the friction surface of a bearing and the surface of a shaft are matched accurately, so that the working performance under the friction environment is guaranteed.

AI Technical Summary

Problems solved by technology

Ball and roller rolling bearings are also used in industrial equipment. The shortcomings of rolling bearings are that the absolutely circular surfaces of bearing sleeves and rolling elements cannot be achieved, and it is impossible to make rolling elements of exactly the same size. The high unit load of the friction part of the bearing parts will cause fatigue spalling, electrochemical corrosion, high requirements on the quality and purity of the lubricating oil, and require sufficient lubrication, etc.
