Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is that a kind of helical-lobe compressor gearbox input shaft mechanical sealing element is provided to related domain, makes it solve the technical problem of existing like product sealing effect and less reliable.Its objective is and be achieved through the following technical solutions.
A kind of helical-lobe compressor gearbox input shaft mechanical sealing element, this mechanical sealing element comprises axle sleeve, rotating ring, stationary ring, gland, and axle sleeve is used for the socket gearbox input shaft, and gland is fixedlyed connected with gearbox end surfaces.Its structure outline is that described axle sleeve one end is provided with baffle ring, the axle sleeve the other end is inserted in spring, throw-out collar, rotating ring O shape circle, rotating seat, rotating ring, stationary ring, stationary ring rubber pad, gland, jump ring successively, described spring keeps impaction state, described axle sleeve inner ring is provided with axle sleeve O shape circle, and described gland one side is provided with gland O shape circle.Above-mentioned mechanical sealing element, the planar slide sealing by rotating ring and stationary ring, and rotating ring O shape circle, thus form sealing when axle sleeve is rotated and between the gland; By the axle sleeve O shape circle that is provided with in the axle sleeve, thereby make axle sleeve and gearbox input shaft form sealing; Gland O shape circle by the gland side makes to form sealing between gland and the gearbox end surfaces, more than each sealing configuration namely formed a kind of mechanical sealing element that prevents that compressor internal gear oil from leaking.And this kind mechanical sealing element is unit loading type, and it is comparatively convenient to assemble, dismantle.
Described rotating seat inner ring end is provided with the rotating ring seal groove, and described rotating ring O shape circle is installed between rotating ring seal groove and the described throw-out collar.Rotating ring O shape circle is realized between rotating seat and the throw-out collar, and the sealing between rotating seat and the axle sleeve.
Described gland side face is provided with screw hole, and screw hole cooperates screw to be used for the fixing of gland and compressor gearbox end surfaces.
Described axle sleeve one end both sides are provided with the keyway of symmetry, and keyway cooperates key pin to be used for the location of axle sleeve on gearbox input shaft.
Described jump ring pushes against described spring, throw-out collar, rotating ring O shape circle, rotating seat, rotating ring, stationary ring, stationary ring rubber pad, gland between jump ring and described baffle ring, and described stationary ring rubber pad, gland are placed in stationary ring end angle external diameter successively.
The utility model structure is comparatively simple, the mechanical sealing element that belongs to unit loading type, it is comparatively convenient to assemble, keep in repair, good sealing effect, reliability height, can prevent effectively that compressor internal gear oil from leaking, the mechanical sealing element that is suitable as the helical-lobe compressor gearbox input shaft uses, or the architecture advances of like product.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
The name of sequence number is called among the figure: 1, axle sleeve, 101, keyway, 102, baffle ring, 2, jump ring, 3, axle sleeve O shape circle, 4, gland, 401, screw hole, 5, gland O shape circle, 6, the stationary ring rubber pad, 7, stationary ring, 8, rotating ring, 9, rotating seat, 10, rotating ring O shape circle, 11, throw-out collar, 12, spring.
Embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in the figure, this helical-lobe compressor gearbox input shaft mechanical sealing element comprises axle sleeve 1, axle sleeve O shape circle 3, jump ring 2, gland 4, gland O shape circle 5, stationary ring rubber pad 6, stationary ring 7, rotating ring 8, rotating seat 9, rotating ring O shape circle 10, throw-out collar 11, spring 12, axle sleeve one end is provided with two symmetrically arranged keyways 101, the axle sleeve the other end is provided with the baffle ring 102 of evagination, the inner axle sleeve O shape circle of installing of axle sleeve.Above-mentioned spring, throw-out collar, rotating ring O shape circle, rotating seat, rotating ring, stationary ring, stationary ring rubber pad, gland are inserted in from axle sleeve keyway end successively, and by jump ring above-mentioned each parts are limited between jump ring and the axle sleeve baffle ring, and spring remains impaction state.The offset installed inside rotating ring O shape circle of an end of rotating seat and throw-out collar, under spring action, rotating ring O shape circle is realized between throw-out collar and the rotating seat and the sealing between rotating seat and the axle sleeve.Rotating ring places in the rotating seat, and stationary ring places in the stationary ring rubber pad, under spring action, forms the planar slide sealing between rotating ring and the stationary ring.Because the rubber property of stationary ring rubber pad can be formed directly in sealing between stationary ring rubber pad and the gland.Circumferential surface at gland is provided with screw hole 401 and seal groove, be provided with gland O shape circle in the seal groove, when gland with after the helical-lobe compressor gearbox end surfaces is fixedlyed connected by screw, gland O shape circle is realized the sealing between gland and the helical-lobe compressor gearbox end surfaces, and the axle sleeve O shape circle in the axle sleeve is realized the sealing between axle sleeve and the helical-lobe compressor gearbox input shaft.By above-mentioned sealing configuration, can prevent effectively that compressor internal gear oil from leaking.
