Problems solved by technology

However, when the bearing is working, not only rolling friction but also sliding friction will occur between the rings, rolling elements and cage, which will cause the bearing parts to wear continuously. The existing bearing steel materials cannot meet the wear resistance and serviceability of the bearing. life

Abstract

The invention discloses a wear-resistant sealed bearing. The wear-resistant sealed bearing comprises a bearing ring I, a bearing ring II, a rolling body and a cage; an annular rolling way is formed between the bearing ring I and the bearing ring II; the rolling body is arranged in the annular rolling way through the cage; the section of the bearing ring I is [-shaped; the bearing ring I includes a ring body and a ring stopper; the ring stopper is arranged on the side surface of the ring body; a gap d is formed between the ring stopper and the bearing ring II; an oil film layer is arranged on the surface of the rolling body; and wear resistant layers are respectively arranged on the surfaces, near the rolling body, of the bearing ring I and the bearing ring II. The wear-resistant sealed bearing is simple in structure, higher in wear resistance and higher in tightness, and needs no independent sealed structure.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a wear-resistant sealed bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment and are widely used. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. With the development of technology, the use of bearings is becoming more and more extensive, and its requirements are becoming more and more special, and sealing and wear resistance are important indicators for bearings. [0003] The sealing structure of the existing sealed bearing uses an independent sealing ring to be assembled in the bearing. Due to the independent sealing structure design, the sealing performance of this kind of bearing can usually meet the requirements; but this kind of bearing needs to reserve a corresponding sealing ring inside the bearing. space, and usually require ...
