Abstract
An air seal body mainly solves the problem in the prior art that overlarge clearance and eccentricity are caused as the air seal body can only be mounted in halves. The air seal body comprises an upper seal body (1), a lower seal body (2) and a seal fixing ring (3), wherein the with seal teeth (4) and the seal cavity (6) are formed on the upper seal body (1); and the upper seal body (1) and the lower seal body (2) are fixedly fastened through the seal fixing ring (3). The utility model has the advantages of reasonable structure and high assembly precision, and can effectively narrow the seal clearance, so as to reduce the medium leakage and improve the equipment efficiency; and the air seal body can further solve the problem that static seal pieces (including bearings) in the positions corresponding to a rotary component need to be integrally mounted, and can be either used in a newly-designed rotary machine or partly transformed according to the structure, so as to guarantee the long-period running of units.
Description
Technical field
The utility model relates to a kind of air sealing, is mainly used in the worm gear machine rotary component, belongs to worm gear machine manufacturing and applied technical field.
Background technique
Existing worm gear machine rotary component air sealing, its rotary component structure is to rotate around center line, radial dimension has nothing in common with each other, and again different black boies can be installed at each shaft part simultaneously.Sometimes be subjected to the influence sealing of revolving part structure can only adopt branchs half to install, be subject to processing make and situation that assembly precision limits under, just can not well implement the thought of revolving part global design, will cause excesssive gap and cause problem such as off-centre.Because the defective on the said structure makes the split position not cause the leakage of working medium well closing, this sometimes leakage is unallowed fully.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned prior art, because the technical problem that the influence of structure can only adopt branch half to install.In order to address this problem, the utility model adopts new structural entity to install, that is: the novel air sealing of split sealing overall package.For achieving the above object, the utility model adopts following technical proposals: air sealing comprises on the seal body that is shaped on sealing tooth (4) and Seal cage (6) (2) and sealing and fixing ring (3) under (1), the seal body.Sealing and fixing ring (3) tightens up (2) under (1) and the seal body on the seal body.
On the above-mentioned seal body under (1) and the seal body (2) integral body add man-hour just unified be processed into cooperates tight, precision height, the fine thread that can loosen simultaneously (5).And according to the size of the sealing and fixing ring (3) of concrete spatial design integral body, so when mounted can be earlier the sealing and fixing ring set on rotary component, and then the upper and lower two halves of split seal are put into correct mounting point, and with the mode of rotary seal retaining ring split sealing integral body is put together on the rotor rotated, install with rotary component is unified then.
The utility model is rational in infrastructure, and its split sealing overall package can solve the problems such as off-centre that cause owing to excesssive gap substantially.Can fully guarantee assembly precision, thereby reduce the leakage that seal clearance reduces medium, improve equipment work efficient.Can also solve simultaneously the problem (comprising bearing) of static element need integral installation on rotary component and the corresponding position, can in newly-designed rotating machinery, use, also can carry out local flow improvement, guarantee the long-term operation of unit by this structure.

Embodiment
Embodiment
See figures.1.and.2, air sealing comprises on the seal body that is shaped on sealing tooth 4 and Seal cage 61, under the seal body 2 and sealing and fixing ring 3.Sealing and fixing ring 3 with on the seal body 1 and seal body under 2 tighten up.
On the above-mentioned seal body 1 with seal body under 2 add just unified processing fine thread 5 in man-hour in integral body, and according to the size of the sealing and fixing ring 3 of concrete spatial design integral body, so when mounted can be earlier the sealing and fixing ring set on rotary component, and then the upper and lower two halves of split seal are put into correct mounting point, and with the mode of rotary seal retaining ring split sealing integral body is put together on the rotor rotated, install with rotary component is unified.
