Abstract
A front-rear fine tuning structure of a magnetic fluid sealing device comprises a coaxial shell, magnetic seal parts, a magnetic rotary shaft and bearings. The magnetic seal parts are disposed on two sides of the magnetic transmission shaft. The bearings on two sides of each magnetic seal part are used for fixing the magnetic transmission shaft and the coaxial shell. The front-rear fine tuning structure further comprises maintaining shafts. Each maintaining shaft is disposed between each magnetic seal part and the magnetic transmission shaft. Each mainlining shaft closely attaches to the seal side of the magnetic transmission shaft. Limit shaft clamps are disposed on the magnetic transmission shaft at two ends of each maintain shaft. The front-rear fine tuning structure has the advantages that by the structure, magnetic fluid sealing relies on matched mounting of equipment parts, and machining precision requirements of related matched parts are lowered.
Description
Technical field
The utility model relates to the seal arrangement of a kind of engineering element or parts, relates to specifically a kind of front and back fine tuning structure of magnetic fluid seal device.
Background technique
In prior art, by magnetic field by magnetic fluid be fixed on running shaft surrounding, form the seal arrangement of on-mechanical contact, be widely used in the manufacturing mechanisms such as semiconductor solar cell and LED; Existing device for sealing magnetic fluid sealing technique can only accomplish to carry out rotary seal on magnetic transmission axle, cannot in magnetic transmission axle front-rear reciprocation movement, seal, need to be after magnetic fluid seal device be installed for current partial vacuum manufacturing mechanism, its magnetic transmission axle need to be in the fine setting of moving of front and back, the mounting point skew causing to adapt to the cumulative error of equipment temples.
Model utility content
The purpose of this utility model is in order to provide a kind of rational in infrastructure, the front and back fine tuning structure of the magnetic fluid seal device of adjustable magnetic fluid seal apparatus alignment error.
In order to reach the purpose of this utility model, technological scheme is as follows:
A kind of front and back fine tuning structure of magnetic fluid seal device, comprise coaxial shell, magnetic seal parts, magnetic transmission axle and bearing, described magnetic seal parts are located at the both sides of magnetic transmission axle, the bearing of described magnetic seal parts both sides is for fixed magnetic transmission shaft and coaxial shell, it is characterized in that: also comprise retainer shaft, described retainer shaft is located between magnetic seal parts and magnetic transmission axle, described retainer shaft is close to magnetic transmission shaft sealing side, describedly on the magnetic transmission axle at retainer shaft two ends, is provided with position-limited shaft card.
As preferred technological scheme: the two axial ends of described retainer shaft is apart from position-limited shaft card 2mm～5mm.
As preferred technological scheme: also comprise stationary axle card, described stationary axle clamping is by bearing two ends, relative static in order to fixing magnetic seal parts and retainer shaft position.
As preferred technological scheme: also comprise seal ring, described seal ring is located between retainer shaft and magnetic transmission axle, in order to keep the vacuum seal between magnetic transmission axle and retainer shaft.
