Abstract
The utility model relates to an axial compensation sealing device mainly for solving the problem of leakage due to wearing of an axial component, which comprises a rotation axis, an end cap fixed to the external wall of an axle hole, and an O-shaped seal washer, wherein, the discoid end cap on the external end face of the rotation axis is fixedly connected with a ladder-shaped cylindrical static ring; the O-shaped seal washer is arranged between the external wall of the rotation axis and the internal wall of a ladder-shaped cylindrical motional ring which is arranged around the surface of the rotation axis body and rotates synchronously with the rotation axis; a cylindrical compensation sleeve which is connected with the static ring through threads is suitably arranged around the external wall face of the motional ring; a magnetic coating layer is inlayed in the external end face of the static ring opposite to ladder-shaped end face of the motional ring, and an external end face of the compensation sleeve is in contact with the ladder-shaped end face of the motional ring. The utility model is simple in structure, easy in maintenance and operation, low in labor intensity, quick as well as time and labor saving. Moreover, the utility model can be repaired without stoppage of equipment with short equipment idling time, high efficiency and long life-span.
Description
Technical field
The utility model relates to a kind of seal arrangement of machinery, especially a kind of nose balance seal arrangement of rotatingshaft.
Technical background
At present, the transmission shaft of mechanical field adopts the sealing configuration of axis body end face more and since be installed in the axis body surface each zero, parts are rigid construction, wearing and tearing in various degree can take place in Sealing in the movement process of rotatingshaft high speed rotating; Cause equipment the phenomenon of revealing after running a period of time, can occur; So need the Sealing that regular shutdown will easily be worn and torn to carry out repair and replacement, not only influence is normal produces, and wastes time and energy.
Summary of the invention
The purpose of this utility model provides a kind of nose balance seal arrangement that keeps in repair that do not need to shut down.
For achieving the above object, the utility model nose balance seal arrangement has rotatingshaft, the end cap affixed with the axis hole outer wall, parts such as O RunddichtringO, the discoid end cap that wherein is positioned at the rotatingshaft exterior edge face is fixedlyed connected with the cylindric stationary ring of ladder, be set between the inwall of the cylindric rotating ring of ladder that rotates synchronously with rotatingshaft on rotatingshaft axis body surface and the rotatingshaft outer wall and be provided with the O RunddichtringO, be sleeved on the outer wall surface of rotating ring adaptedly by the cylindric compensation sleeve that is threaded with stationary ring, the stationary ring exterior edge face relative with the ladder end face of rotating ring is inlaid with magnetisable coating, and an exterior edge face of compensation sleeve contacts with the ladder end face of rotating ring.
After adopting said structure, because stationary ring exterior edge face relative with the ladder end face of rotating ring and rotating ring produce magnetic attracting force, so drive the frictional contact surface that is closely closing with the ladder end face of exterior edge face of the cylindric compensation sleeve of stationary ring by being threaded to one and rotating ring, wear and tear as the compensation sleeve exterior edge face that rotatingshaft contacts with rotating ring in rotary course, rotating ring can move axially along rotatingshaft; Another exterior edge face of rotation compensation sleeve moved axially the compensation sleeve to drive rotating ring and resetted this moment.Realize the maintenance under the non-shutdown working state, avoid changing the problem that wear-out part appearance influence is produced, thereby enhance productivity because of regularly shutting down.
The utility model has the advantages that: simple in structure, maintenance is easy, quick, time saving and energy saving, labor intensity is low, can under the non-stop-machine state of equipment, keep in repair, the time that equipment is stopped transport is short, high working efficiency, long service life.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model nose balance seal arrangement.
Embodiment
Show as Fig. 1, the utility model nose balance seal arrangement has rotatingshaft 1, with the axis hole outer wall by screw thread or the end cap 2 that is welded to connect, O RunddichtringO 6, the discoid end cap 2 that wherein is positioned at rotatingshaft 1 exterior edge face is bolted to connection with the cylindric stationary ring 5 of ladder, be set between the inwall of the cylindric rotating ring 3 of ladder that rotates synchronously with rotatingshaft 1 on rotatingshaft 1 axis body surface and rotatingshaft 1 outer wall O RunddichtringO 6 is installed, be sleeved on the outer wall surface of rotating ring 3 adaptedly by the cylindric compensation sleeve 4 that is threaded with stationary ring 5, stationary ring 5 exterior edge faces relative with the ladder end face of rotating ring 3 are inlaid with magnetisable coating, perhaps rotating ring and stationary ring are made by two different magnetic materials, and an exterior edge face of compensation sleeve 4 contacts with the ladder end face of rotating ring 3.
Because stationary ring exterior edge face relative with the ladder end face of rotating ring and rotating ring produce magnetic attracting force, so drive the frictional contact surface that is closely closing with the ladder end face of exterior edge face of the cylindric compensation sleeve of stationary ring by being threaded to one and rotating ring, wear and tear as the compensation sleeve exterior edge face that rotatingshaft contacts with rotating ring in rotary course, rotating ring can move axially along rotatingshaft; Another exterior edge face of rotation compensation sleeve moved axially the compensation sleeve to drive rotating ring and resetted this moment.Form the Seal cage of sealing.Can visual structure be installed in the outer wall surface of equipment in the use, the compensation sleeve end face that commute takes place to wear and tear is carried out regular monitoring, and the situation according to wearing and tearing in time compensates adjustment at any time.
The utlity model has characteristics such as simple in structure, that maintenance is easy, quick, time saving and energy saving, and labor intensity is low, can under the non-stop-machine state of equipment, keep in repair, thus the efficiency of equipment height, long service life.
