Abstract
The utility model discloses a sealed rotary shaft which comprises a rotary shaft, a gland and a mechanical seal. The gland is sleeved on the rotary shaft, the mechanical seal is arranged between the rotary shaft and the gland and comprises a rotary seal and a fixed seal, the rotary seal is sleeved on the rotary shaft and is fixedly connected with the rotary shaft, and the fixed seal is sleeved on the rotary shaft and is fixedly connected with the inner wall of the gland. The sealed rotary shaft has the advantages that the rotary seal replaces a planar seal, accordingly, the sealed rotary shaft is good in seal performance, and the service life of the rotary shaft and the service lives of sealing parts are prolonged.
Description
Technical field
The utility model relates to a kind of running shaft, specifically, relates to a kind of sealing rotary rotating shaft.
Background technique
Conventionally, the transmission rotational axis designing in machinery equipment, You position need to be immersed in some liquid, because axle is a solid of rotation, in order to guarantee that running shaft can seepage liquid, conventionally at an outside framework oil seal of needs sealing station design, be placed on running shaft, be rotated formula sealing, but such method, there is certain drawback: in outside framework oil seal position, easily wear and tear, easily running shaft is worn into an annular groove, will produce seepage like this, particularly, at some chemical fields, more can cause very large loss and danger; Separately, due to seepage, running shaft is easily corroded or oxygenated, and finally causes reduce the working life of running shaft and Sealing.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of rotary seal to convert plane sealing to, the sealing rotary rotating shaft of good seal performance, long service life.
For achieving the above object, the technical solution of the utility model is as follows: a kind of sealing rotary rotating shaft, comprise running shaft, be sheathed on the gland on described running shaft and be arranged at the mechanical seal between described running shaft and gland, described mechanical seal comprises rotary seal and fixing seal, described rotary seal is sheathed on described running shaft and is fixedly connected with described running shaft, and described fixing seal is sheathed on described running shaft and is fixedly connected with the inwall of described gland.
Further, described rotary seal internal surface is embedded with seal ring.
Further, between the outer surface of described fixing seal and the internal surface of gland, be also provided with seal ring.
Further, the end of described gland is radially equipped with screw, and the end of described screw is positioned at the free end of described fixing seal.
Further, the wearing face of described rotary seal and fixing seal is oppositely arranged and contacts.
Further, the material of described wearing face is graphite alloy.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: the setting of rotary seal and fixing seal, make to convert the rotary seal of running shaft to plane sealing, and improved the sealability of running shaft, can not infilter liquid, extend the working life of running shaft and Sealing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment technology, to the accompanying drawing of required use in embodiment's technical description be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of sealing rotary rotating shaft of the utility model.
Wherein, 1, running shaft, 2, gland, 3, rotary seal, 4, fixing seal, 5, seal ring, 6, seal ring, 7, screw, 8, fixing body, 9, liquid.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of sealing rotary rotating shaft, be soaked in liquid 9, comprise running shaft 1, be sheathed on the gland 2 on running shaft 1 and be arranged at running shaft 1 and gland 2 between mechanical seal, one end of gland 2 is fixedly connected on fixing body 8, mechanical seal comprises rotary seal 3 and fixing seal 4, rotary seal 3 is sheathed on running shaft 1 and is fixedly connected with running shaft 1, when running shaft 1 rotation, rotary seal 3 can be along with running shaft 1 rotates together, relative and running shaft 1 is state of rest, fixing seal 4 is sheathed on running shaft 1 and is fixedly connected with the inwall of gland 2, can not rotate along with the rotation of running shaft 1.
Wherein, rotary seal 3 internal surfaces are embedded with seal ring 5, between the internal surface of the outer surface of fixing seal 4 and gland 2, are also provided with seal ring 6.The end of gland 2 is radially equipped with screw 7, and the end of screw 7 is positioned at the free end of fixing seal 4, so fixing seal 4 can not produce displacement to the right.The wearing face of rotary seal 3 and fixing seal 4 is oppositely arranged and contacts.
All the other are same as the previously described embodiments, and difference is, the material of wearing face is graphite alloy.
Embodiment 3
All the other are same as the previously described embodiments, and difference is, the number of screw 7 is set to four, along the circumferential uniform setting of this gland, makes whole can being fixed of free end of whole fixing seal 4, can not be subjected to displacement.
Pass through technique scheme, the beneficial effect of technical solutions of the utility model is: the setting of rotary seal and fixing seal, make to convert the rotary seal of running shaft to plane sealing, and improved the sealability of running shaft, can not infilter liquid, extend the working life of running shaft and Sealing.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To these embodiments' multiple modification, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
