A slewing support device and its main shaft for deep ocean current generation

Abstract

The invention provides a rotation supporting device and a deep ocean current electricity generation main shaft the with rotation supporting device. The rotation supporting device comprises a fixed connection portion, a shaft connector, a press plate, a plurality of thrust balls and a plurality of rotating balls, wherein the press plate, the thrust balls and the rotating balls are arranged in the fixed connection portion in a storage mode. A supporting plate which encircles the shaft connector is arranged on the outer side wall of one end of the shaft connector, a bearing column is arranged at the end of the shaft connector, and the bearing column and the supporting plate are held in the fixed connection portion. The other end of the shaft connector is coaxially connected with the deep ocean current electricity generation main shaft. A first gap exists between the supporting plate and the inner side wall of the fixed connection portion. The thrust balls are arranged by encircling the bearing column. The press plate is fixedly arranged on the outer side wall of the shaft connector, and encircles the shaft connector, and a second gap exists between the press plate and the inner side wall of the fixed connection portion. The rotating balls are held in a holding cavity which is mainly defined by the shaft connector, the press plate, the fixed connection portion and the supporting plate, the rotating balls are arranged by encircling the shaft connector, the diameter of each rotating ball is smaller than that of the corresponding thrust ball, and each rotating ball is tangent to the inner wall of the holding cavity in the top, bottom, left and right directions.

Description

technical field [0001] The invention relates to a rotary support device, in particular to a rotary support device for a deep ocean current power generation main shaft and the deep ocean current power generation main shaft. Background technique [0002] There are many types of power generation devices, but there are many problems, such as thermal power generation, carbon dioxide pollution caused by large-scale combustion, coal burning pollution, etc. Wind power generation is a clean energy, but wind power generation is restricted by region, and wind power does not always maintain a state. And the investment of existing wind power generators is tens of millions, the investment funds are too large, and the input-output ratio is small. [0003] Hydropower is also a kind of clean energy. The existing method of hydropower generation is mainly to build dams to store water for power generation. The impact of this method on the environment cannot be measured for the time being, but t...

Problems solved by technology

But in practice, it is found that the main shaft load of the power generation device is large, and there are many force-bearing blades connected to the main shaft. Thrust bearings are very expensive. When used for this kind of underwater power generation, due to corrosion problems, the frequency of bearing replacement is relatively high. At this time, if ordinary thrust bearings are used, the production cost will increase a lot.
