Problems solved by technology
[0005] However, these technical solutions all have a common feature: the structural parts in the slewing support device, such as supporting parts, loading parts, and clamping parts, are all loaded by cantilever, and the force transmission path is complicated. It is very unfavorable for the transmission of the transmission and the bearing of related parts, which affects the reliability of the slewing bearing components, and then affects the reliability of the whole machine operation.

The invention discloses a sliding slewing bearing device and a wind generating set. The sliding slewing bearing device at least comprises a supporting piece, a clamping piece, a friction piece, a loading piece and a bearing piece. The supporting piece is of a disc annular structure, the outer edge and the inner edge of the first end face of the supporting piece are each provided with at least one clamping piece, and the clamping pieces bear loads from the loading piece through the friction pieces. The second end face of the supporting piece bears or transmits the load from the loading piece through the friction piece. When the supporting piece is fixedly connected with the bearing piece, the double-side clamping piece is fixedly connected with the loading piece, and the double-side clamping piece and the friction piece rotate relative to the supporting piece; or the supporting piece is fixedly connected with the loading piece, the double-side clamping piece is fixedly connected with the bearing piece, and the supporting piece and the loading piece rotate relative to the clamping piece, the friction piece and the bearing piece. Compared with a conventional scheme, the sliding slewing bearing device disclosed by the invention has the advantages that load transmission is more reasonable, the bearing capacity is higher, and the operation reliability of a wind turbine generator is higher.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a sliding support device and a wind power generating set. Background technique [0002] Wind power is the power generation method with the most large-scale development value and commercial development prospects in the field of renewable energy. The available wind energy is widely distributed around the world and has huge reserves. With the development of society, the utilization of wind energy has been paid more and more attention by various countries, and the technology of wind power generation is also constantly improving. The slewing bearing structure is an important structure in the wind turbine, such as the yaw system and the pitch system. The slewing support structure in the wind turbine has the functions of support and slewing. For example, the main function of the yaw system is not only to yaw against the wind, so that the impeller can capture t...
