Mechanical seal following floating

Abstract

The invention discloses a mechanical seal following floating. The mechanical seal comprises a fixed seat A, an end face sealing part D, a sealing part of the fixed seat A, an end face sealing seat B,an end face sealing part E inlaid on the end face sealing seat B in a sealed mode, a fixed seat C, an axial sealing part F of the fixed seat C, a rubber sleeve, a spring and a guiding shaft; the sealing part of the fixed seat A is clamped between a shell and the fixed seat A, the fixed seat A is fixed to the shell through a bolt, and the fixed seat C is fixed to a shaft through a set screw; the guiding shaft is mounted on the outer sides of the two sides of a groove formed by the fixed seat C and the end face sealing seat B, one end of the guiding shaft is fixed to the fixed seat C, the springsleeves the guiding shaft, the other end of the guiding shaft is inserted into a hole of the end face sealing seat B, and the end face sealing part D and the end face sealing part E are mounted between the fixed seat A and the end face sealing seat B; and the rubber sleeve is mounted on the inner side of the groove, one end of the rubber sleeve is mounted on the fixed seat C, the other end of therubber sleeve is mounted on the end face sealing seat B, the axial sealing part F is mounted between the fixed seat C and the shaft, and thus the mechanical seal following floating is constituted.

Description

technical field [0001] The invention relates to a kind of working condition mechanical reducer or roller due to the large load-carrying load, which causes oil leakage between the shell and the shaft in the radial and axial directions, and then solves the problem of oil leakage with a floating mechanical seal, especially for rollers or rollers. The output shaft of the reducer bears a large torque, which causes the floating mechanical seal to follow the large clearance of the shaft and the bearing. Background technique [0002] The seal is a necessary part for the reducer to seal, lubricate and change oil in the transmission equipment under working conditions. The seal between the existing reducer (or drum) shell (cylinder) and the shaft is a skeleton seal or a mechanical dynamic seal. Relative rotation requires that the lip of the skeleton oil seal be coaxial with the shaft of the reducer (or pulley) to ensure good sealing. The reducer (or pulley) is often operated for a long...
