Abstract
The invention relates to a sealing structure for industrial machinery. The sealing structure comprises a connecting plate, wherein a positioning ring is arranged in the connecting plate; a contact surface between the positioning ring and the connecting plate is of a step shape; the positioning ring is in contact with a lower friction plate; the lower friction plate is in contact with an upper friction plate; a rotating rod is arranged at the center of the positioning ring; the upper side of the upper friction plate is connected with a moveable ring; the upper side of the moveable ring is in contact with a tensioning spring; and the upper end of the tensioning spring is in contact with a locking nut. The sealing structure for industrial machinery is simple and reasonable in design. According to the invention, the positioning ring, the lower friction plate, the upper friction plate and the tensioning spring are arranged, so that the mutual tensioning of the positioning ring, the lower friction plate and the upper friction plate can be realized through the tensioning spring, a better sealing property can be achieved and the requirement of industrial production can be met.
