Roller bearing for supporting main shaft of wind driven generator

Abstract

The invention discloses a roller bearing for supporting a main shaft of a wind driven generator. The roller bearing for supporting a main shaft of a wind driven generator is prepared from a high-strength alloy steel material, has a single-row tapered roller bearing structure, and comprises an outer ring, an inner ring, a tapered roller, an upper groove which is used for receiving the tapered roller and is located at the outer ring, a lower groove which is used for receiving the tapered roller and is located at the inner ring, a keeper which is used for keeping the tapered roller, an upper lubricant groove which is located at the outer ring and provides lubricant to the tapered roller, and a lower lubricant groove which is located at the inner ring and provides lubricant to the tapered roller, wherein four corners of the tapered roller have arc shapes; the upper groove which is used for receiving the tapered roller and is located at the outer ring and the lower groove which is used for receiving the tapered roller and is located at the inner ring compose a tapered roller receiving groove; and four corners of the tapered roller receiving groove have arc shapes.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a roller bearing for supporting the main shaft of a wind power generator. Background technique [0002] In today's society, with the increasingly serious problems of global energy shortage and environmental pollution, the search for renewable energy has become a major issue faced by countries all over the world. Compared with other energy sources, natural wind energy not only has a large amount of reserves, is widely distributed, and will never be exhausted, but also has the advantages of fast start-up, short construction period, less basic investment than hydropower station construction, strong flexibility, and can effectively curb the greenhouse effect and Sandstorm disasters, green environmental protection and other characteristics, so wind power has increasingly become the focus of research. [0003] As a transmission device, the main shaft of the wind turbine ...

Problems solved by technology

Corresponding arcs are also used to form nuclei-shaped grooves at the parts where the inner and outer rings of the bearing are in contact with the rollers, which can increase the contact angle and contact area, and improve the axial bearing capacity; and effectively avoid the obvious stress concentration of existing roller bearings, The problem of high heat
