Sealing performance testing device for sealing ring of dual-drive large-scale wind power main shaft bearing

Abstract

The invention discloses a sealing performance testing device for a bearing sealing ring of a dual-drive large wind power main shaft, which is provided with a main shaft, two ends of the main shaft are provided with self-aligning bearings, the bottom of each self-aligning bearing is provided with a horizontal moving workbench and a vertical moving workbench, and the right end of the main shaft is connected with a main shaft rotation driving motor; a disc-shaped rack, a left inline simulation ring and a right inline simulation ring are arranged on a main shaft, an internal tooth turntable bearing is arranged on the disc-shaped rack, a left external connection simulation ring and a right external connection simulation ring are arranged on the internal tooth turntable bearing, a left annular mounting groove and a right annular mounting groove are formed in the inner ring surfaces of the left external connection simulation ring and the right external connection simulation ring respectively, a pressing ring is arranged outside the mounting grooves, and an inner oil separation sleeve is arranged between the left inline simulation ring and the right inline simulation ring in a sealed mode. An outer oil separation sleeve is installed between the left external connection simulation ring and the right external connection simulation ring in a sealed mode, an annular oil injection cavity is formed between the inner oil separation sleeve and the outer oil separation sleeve, an inner ring driving motor is further installed on the disc-shaped machine frame, and a brake is installed on an output shaft of the main shaft rotation driving motor. The device can be used for testing the sealing performance of the large-scale wind power main shaft bearing sealing ring.

Description

technical field [0001] The invention relates to a large-scale wind power main shaft bearing sealing ring, in particular to a double-drive large wind power main shaft bearing sealing ring sealing performance testing device. Background technique [0002] The diameter of the main shaft bearing sealing ring of a large wind turbine is relatively large, and it is very difficult to process and manufacture. Since the sealing rings of large-scale wind power main shaft bearings are mainly used in the air and in the field, the working conditions are complex and harsh, and the design and manufacture of the sealing rings cannot be fully considered. It is necessary to repeat the design and manufacture of the sealing rings according to the use effect during use. Improve it to meet the requirements of use. The improvement of the sealing ring is mainly to adjust the shape of the sealing lip, including the height of the sealing lip, the thickness of the waist, etc., as well as the size of th...

AI Technical Summary

Problems solved by technology

Every time the sealing ring is improved, the sealing ring must be disassembled from the bearing of the main shaft of the wind turbine. The disassembly process is cumbersome, which not only reduces the power generation efficiency of the wind turbine, but also increases the cost during the disassembly process. Moreover, If there is a seal failure problem during the operation of the wind turbine, it may also lead to a safety production accident.

[0003] There is no sealing performance test device for large-scale wind power main shaft bearing sealing ring in the prior art
