Mechanical and flexible combined sealing structure for rotating shaft of gearbox

Abstract

The invention discloses a mechanical and flexible combined sealing structure for a rotating shaft of a gearbox. The mechanical and flexible combined sealing structure comprises a body device, wherein a mounting groove is formed in the middle of the right side of the body device; a shaft body is fixedly arranged in the mounting groove; a mounting ring groove is formed in the periphery of the right side in the mounting groove; sealing strip rings are fixedly arranged on the two sides of the interior of the mounting ring groove; and the sides, away from the mounting ring groove, of the sealing strip rings are in contact with the exterior of the shaft body. When the shaft body is mounted in the mounting groove, the sealing strip rings mounted on the two sides of the interior of the mounting ring groove are in fixed contact with the exterior of the shaft body; dust can be prevented from running into the body device through the sealing strip rings when the shaft body rotates; and when the shaft body rotates, lubricating oil is fed into an oil feeding pipe through a pressure regulating valve head and is sprayed between a sealing strip ring and the exterior of the shaft body through an oil feeding spray head, so that the friction force of the sealing strip ring during rotation is reduced through the lubricating oil, the abrasion of the sealing strip ring during rotation can be reduced, and the sealing performance is improved.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a mechanical and flexible combined sealing structure of a rotating shaft of a gearbox. Background technique [0002] The gearbox is an important part widely used in mechanical transmission. The gearbox is widely used in wind turbines. The gearbox must have sufficient rigidity to withstand the force from the wind wheel and the reaction force generated during gear transmission. and the role of torque to prevent deformation and ensure transmission quality; [0003] The traditional mechanical and flexible combined sealing structure of the rotating shaft of a gearbox has the following deficiencies; [0004] At present, the gearbox is widely used in the use of wind power generators, and the connection between the rotating shaft body and the main body device is easy to run into the inside of the connection between the rotating shaft and the main body device during the operation of th...
