Embodiment 1

[0033] refer to Figure 1 to Figure 3As shown, a wind power main shaft seal ring on-site replacement tooling includes a positioning block 1 for installing the seal ring and two pressing blocks 2 that cooperate with the positioning block 1. The positioning block 1 is provided with a positioning groove 11 for positioning The cross-sectional shape of the groove 11 is the same as the outer cross-sectional shape of the sealing ring. The cross-sectional shape of the compression strip 21 is the same as the inner cross-sectional shape of the sealing ring. The positioning groove 11 and the positioning bar can both be linear or concentric circular arcs. The pressing block 2 is arranged opposite to the positioning block 1 , and the sealing ring is located between the pressing block 2 and the positioning block 1 . The side of the compression block 2 facing the positioning block 1 is provided with a compression strip 21, the compression block 2 and the positioning block 1 are fixed by th...

Abstract

The invention discloses a field online replacing tool and method for a wind power main shaft sealing ring. The field online replacing tool comprises a positioning block and a plurality of pressing blocks, wherein the positioning block is used for positioning the sealing ring; the pressing blocks are opposite to the positioning block and are used for pressing the sealing ring; the pressing blocks are detachably fixed to the positioning block, and the sealing ring is positioned between the pressing blocks and the positioning block. The field online replacing tool has the beneficial effects thatclamping of the sealing ring can be quickly accomplished through the tool, field cut-off and field connecting and fixing of the sealing ring can be realized, cutting convenience of the sealing ring can be guaranteed, field connecting and fixing of the sealing ring is convenient, cut aligning during viscose connecting after the cut sealing ring sleeves the main shaft can be guaranteed, a cutting surface lip is precisely in butt joint, bonding strength, sealing performance and service life of the sealing ring are effectively guaranteed, and labor intensity and operation difficulty of a worker are relieved.

Description

technical field [0001] The invention relates to the technical field of wind power engines, in particular to a tool and method for on-site on-line replacement of wind power main shaft sealing rings. Background technique [0002] The main shaft of the wind power generator needs to be provided with a sealing device to solve the problem of main shaft bearing grease leakage. For example, in the Chinese patent document CN 204900831U, the authorized announcement date is December 23, 2015, which is called "a wind power generator main shaft sealing device". ” utility model patent, which discloses a wind turbine main shaft sealing device, including a shaft sleeve fixed on the main shaft and an end cover fixed on the bearing seat, and a seal is formed between the end cover and the shaft sleeve. A labyrinth sealing structure is used to reduce grease leakage inside the sealing device; a sealing member is arranged between the outer surface of the shaft sleeve and the end cover to prevent ...
