Abstract
The utility model discloses a prevent rotating rotary seal circle, including stairstepping sliding ring and O type circle, the stairstepping sliding ring includes as the outer edge portion of first order ladder, as the sealing of second ladder and the supporting part of conduct third ladder, the sealing is equipped with the convex seal groove with the laminating of O type circle, O type circle sets up in convex seal groove, the inner wall of stairstepping sliding ring is equipped with the wave seal lip. The utility model discloses a prevent rotating rotary seal circle will be outward edge portion be embedded into the ditch inslot of equipment, has solved the sliding ring and has followed the rotatory problem of main shaft, avoided the rapid wear of sealing washer, lengthened life, simultaneously outer edge portion can make open slot two parts combine together and produce to seal up, need not additionally increase the static seal within a definite time at two parts slot.
Description
Technical field
This utility model relates to a kind of mechanical sealing member, particularly to a kind of anti-rotation rotating seal ring.
Background technology
Existing rotating seal ring uses in being all integrally fixed at groove, and its slip ring pastes under the support force of O
It is combined on spindle outer wall, when the shaft rotates, for sliding friction between slip ring and main shaft.But in the process of use
In, slip ring is easy to follow main shaft and rotates, and causes and becomes sliding friction between slip ring and O, adds
The acute abrasion of sealing ring, have impact on service life, and it also requires a static seal structure, makes open type ditch
Formed when groove two parts combine and seal.
Utility model content
For solving above-mentioned technical problem, the utility model discloses a kind of anti-rotation rotating seal ring, including rank
Trapezoidal slip ring and O, described stairstepping slip ring includes the outer portion as first order ladder, as
The sealing of two ladders and the supporting part as the 3rd ladder, described sealing is provided with and O laminating
Circular arc seal groove, described O is arranged in circular arc seal groove, and the inwall of described stairstepping slip ring sets
There is waveform sealing lip.
The beneficial effects of the utility model are:
Outer portion is embedded in the groove of equipment by anti-rotation rotating seal ring of the present utility model, solves cunning
Ring follows the problem that main shaft rotates, it is to avoid the Fast Wearing of sealing ring, extends service life, simultaneously outside
Open type groove two parts can be made to combine and produce sealing along portion, need not be additionally between two parts groove
Increase static seal.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below will be to institute in embodiment

Fig. 2 is use state diagram of the present utility model.
Labelling in figure: 1-stairstepping slip ring；11-outer portion；12-sealing；13-supporting part；14-waveform
Sealing lip；2-O type circle；3-main shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.
As depicted in figs. 1 and 2, a kind of anti-rotation rotating seal ring, including stairstepping slip ring 1 and O type
Circle 2, stairstepping slip ring 1 includes the outer portion 11 as first order ladder, sealing as the second ladder
12 and supporting part 13 as the 3rd ladder.
Sealing 12 is provided with and the circular arc seal groove of O 2 laminating, and O 2 is arranged on this circular arc
In seal groove.The inwall of stairstepping slip ring 1 is additionally provided with waveform sealing lip 14, makes stairstepping slip ring 1 with main
Formed multiple-sealed between axle 3, improve sealing property.
During use, outer portion 11 is embedded in the groove of equipment, solves slip ring and follows asking of main shaft 3 rotation
Topic, it is to avoid the Fast Wearing of sealing ring, extends service life.Outer portion 11 can also make open type simultaneously
Groove two parts combine and produce sealing, additionally need not increase static seal between two parts groove.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
