Abstract

The invention discloses a shaft end sealing mechanism. The shaft end sealing mechanism comprises an equipment end plate, a sealing base, a lock nut and a compression sleeve, wherein the sealing base is arranged on the equipment end plate; a rotating shaft is arranged inside the sealing base in a matching way; a sealing material is arranged between the inner cavity of the sealing base and the rotating shaft; the lock nut is arranged on the sealing base; the compression sleeve is arranged on the rotating shaft and is positioned between the sealing material and the lock nut; the lock nut is rotated to drive the rotating shaft to move upwards along the sealing base; and the sealing material is extruded and tensioned by the compression sleeve to realize a shaft end sealing function. According to the shaft end sealing mechanism, an integral spiral pre-tightening structure is adopted together with a ball-type one-way non-return structure, so that rapid pre-tightening and timely locking can berealized by only rotating the lock nut. The tensioning system can keep stable pre-tightening force, and has an automatic compensation function, so that the service life of the sealing material is prolonged greatly.

Description

technical field [0001] The invention relates to a shaft end sealing mechanism, which belongs to the technical field of design of food conditioner sealing mechanism. Background technique [0002] Common conditioners and other equipment in the food, feed and other industries, due to the particularity of their working conditions, often adopt the packing seal method. The packing seal has strong adaptability and low cost. However, after wear and tear, the extrusion amount needs to be adjusted in time to maintain its seal. Effect. The existing packing sealing mechanism often adopts the flange compression method, and the axial extrusion force is provided by the bolts around the flange to meet the pre-tightening requirements of the packing. This method is difficult to ensure uniform extrusion force, resulting in one-sided In addition, all bolts need to be pre-tightened regularly, which requires a lot of work and high maintenance costs. Contents of the invention [0003] The tech...
