Brief description of the drawings
Fig. 1 is the sectional view that a kind of gas seal self-adaptive temperature that the utility model proposes regulates bearing.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation that a kind of gas seal self-adaptive temperature that the utility model proposes regulates bearing.
With reference to Fig. 1, a kind of gas seal self-adaptive temperature the utility model proposes regulates bearing, can be used for being subject to the structure, environmental constraint cannot assembly routine sealing original paper, needs again the occasion of sealing, cooling or heating; This bearing comprises: outer ring 1, inner ring 2, conveying mechanism 3, back-up ring 4, movable ring 5, spring sheet 6;
Outer ring 1 is positioned at inner ring 2 outsides, and conveying mechanism 3 is located between outer ring 1 and inner ring 2, conveying mechanism 3 comprise retainer and and rolling element, rolling element is located in retainer, in installation process, outer ring 1 is fixing, inner ring 2 rotates;
Two back-up rings 4 are interference fitted in the interior week at 1 two ends, outer ring, two movable ring 5 Spielpassung are in the interior week of two back-up rings 4, spring sheet 6 is fixed on back-up ring 4 outer ends by rivet and relies on its elastic force that movable ring 5 is remained between inner ring 2 and back-up ring 4, between the interior week of two movable rings 5 and the periphery of inner ring 2, forms annular gap; Be provided with labyrinth seal structure in movable ring 5 peripheries, prevent that inner chamber gas is from too much leakage contribution heat transfer effect between back-up ring 4 and movable ring 5;
Between outer ring 1, inner ring 2, back-up ring 4, movable ring 5, form bearing cavity, on outer ring 1, be provided with the inlet hole 7 being communicated with described bearing cavity, multiple inlet holes 7 are evenly arranged on outer ring 1, and the annular gap between movable ring 5 and inner ring 2 is to be communicated with the air outlet hole 8 of described bearing cavity to chamber; Particularly, conveying mechanism 3 is divided into described bearing cavity the clutch shaft bearing inner chamber and the second bearing cavity that are positioned at its both sides, is provided with the inlet hole 7 being communicated with described clutch shaft bearing inner chamber and described the second bearing cavity on outer ring 1;
In seal process, outer ring 1 is provided with inlet hole 7, allows the gas with certain pressure enter bearing cavity, and the annular gap between inner ring 2 and movable ring 5 forms gas port 8 for Exhaust Gas, blow the extraneous next foreign material such as dust, moisture content off, realize the gas seal of bearing; In order to seal better, the diameter that annular gap is set is increased gradually by outer end to the inner, and the diameter of annular gap outer end is less than its inner diameter.
In the course of the work, the size of air outlet 8 apertures can change along with the size of bearing cavity pressure automatically, when chamber pressure is large, air outlet 8 apertures are large, otherwise little, adjust the aperture of pore 8 according to the temperature height in described bearing cavity, thereby regulate the gas flow that flows through described bearing cavity.
