Floating seal ring working abrasion gap adjustment compensation device

Abstract

The invention provides a floating seal ring working abrasion gap adjustment compensation device. The adjustment compensation device is mounted on a movable seat cavity, a floating seal ring and a rubber ring are installed in the movable seat cavity, the movable seat cavity and a shaft are sealed through a shaft sealing rubber ring, an adjusting screw hole is formed in the center of the shaft in the axial direction, a clamping pin position groove running through the shaft is formed in the outer side of the shaft in the radial direction, a clamping pin is installed in the clamping pin position groove, a clamping pin groove position is formed in the outer end of a shaft hole of the movable seat cavity, a clamping pin is inserted into a shaft clamping pin groove, and meanwhile, after the clamping pin is clamped into the clamping pin groove position at the outer end of the shaft hole of the movable seat cavity, a linkage body formed by combining the clamping pin, the shaft and the movable seat cavity is linked with the shaft and rotates along with the shaft. The end of the shaft is provided with an adjusting screw rod inserted into the adjusting screw hole, one end of the adjusting screw rod is located outside the end of the shaft, and the other end of the adjusting screw rod penetrates through the adjusting screw hole to be in contact with the clamping pin. By means of the device,the working abrasion gap of the floating seal ring is variable and adjustable, random abrasion compensation can be carried out, and the service life of the floating seal ring can be prolonged in multiples.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a working wear gap adjustment and compensation device for a floating seal ring. Background technique [0002] The sealing performance and working life of the floating oil seal are the core indicators of its quality. Oil leakage is a key sign of failure of the floating seal ring. There are many reasons for oil leakage, and among them, the long working hours, insufficient elastic force of the apron, unable to make up for the abrasion of the working surfaces of the two iron rings, the gap between the fitting surfaces becomes larger, and the leakage is the most direct and common reason. At this time, replacing the floating seal is the only option. However, if the design can be changed so that the installation of the floating seal ring and the setting of the working pressure are variable and adjustable, and random wear compensation can be performed, the service life of the fl...

Problems solved by technology

There are many reasons for oil leakage, among which the working hours are long, the elastic force of the apron is insufficient, and it cannot compensate for the wear of the working surfaces of the two iron rings, so that the gap between the fitting surfaces becomes larger, and the leakage is the most direct and common reason.
