Description
Technical Field
The utility model relates to a connecting axle seal structure specifically indicates a connecting axle seal structure for reducing gear box.
Background
The reduction gearbox is used as a mechanical transmission device, plays a role in matching rotating speed and transmitting torque between a prime motor and a working machine or an actuating mechanism, is widely applied to modern machinery, because the structure and the tightness of the reduction gearbox are unreasonable, the oil leakage and oil seepage of the reduction gearbox often result in, when the oil leakage is serious, the reduction gearbox cannot be normally lubricated in due to the oil shortage, so that the gear is damaged, and through analysis, the position where the oil leakage of the reduction gearbox is most difficult to prevent is a connecting shaft hole, the sealing is generally carried out through an O-shaped sealing ring, but the sealing effect is poor, and along with the use time, the sealing effect is gradually reduced, so that a large amount of lubricating oil is leaked.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a connecting axle seal structure for reducing gear box.
In order to solve the technical problem, the utility model provides a technical scheme is a connecting axle seal structure for reducing gear box: including the box, set up in the shaft hole and the connecting axle of box lateral wall, be equipped with sealing washer and bearing in the shaft hole, connecting axle one end runs through bearing and sealing washer in proper order inside and extend to the box outside, the shaft hole inner wall is kept away from box one end and is equipped with the internal thread, the sealing washer outer peripheral face is close to box one end and is equipped with the external screw thread with internal thread threaded connection, the connecting axle is located the inside axis body of sealing washer and is equipped with first sealing ring along the axis direction, the sealing washer inner wall is equipped with the second sealing ring with the.
As a modification, the outer peripheral surface of the first sealing ring is provided with sealing teeth along the axial direction.
As an improvement, the sealing ring is formed by buckling two semicircular sealing rings, and the semicircular sealing rings are fixedly connected through an inner hexagonal bolt.
Compared with the prior art, the utility model the advantage lie in: through the improvement of connecting axle and sealing washer structure, reinforcing reducing gear box shaft hole sealing effect improves sealed effective service life.
