Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
See Fig. 1, Fig. 2: a kind of seal arrangement, its structure mainly are made of axle sleeve 2, rotating seat 4, rotating ring 6, quiet assembly 4, branch semi-ring 2 etc.
Described axle sleeve 2 inboards are provided with Sealing 1, described Sealing 1 is fluorine rubber circle, the flexible assembly 3 of the arranged outside of described axle sleeve 2, push up mutually with rotating seat 4 at the top of described elastic component 3, and push up mutually with axle sleeve 2 bottom, described rotating seat 4 is provided with anti-relative whirligig with axle sleeve 2, described anti-its structure of relative whirligig is that described rotating seat 4 is provided with fork pin 13, tapped hole 14, described fork pin 13 stretches into driving groove 11, and bolt 9 passes hole 12 and top and tapped hole 14 and spins together.The transmission that cooperates of axle sleeve 2 and rotating seat 4 efficiently solves and occurs rotation easily when self-alignment axle sleeve and rubber corrugated pipe are engaged in transmission in the prior art and skid, thereby produces the problem of seal leak.
As preferably, elastic component 3 is a spring, and according to the size of institute's seal arrangement, can be set to cluster spring, also can be single spring.
As preferably, driving groove 11 is provided with 3, and is distributed on the bottom of axle sleeve 2, and also corresponding uniform being arranged on the rotating seat 4 of fork pin 13 can prevent effectively that axle sleeve 2, rotating seat 4 rotations from skidding.
Described rotating seat 4 inside top are provided with rotating ring protection structure, and described rotating ring protection structure comprises bellows 5, and described bellows 5 tops are provided with groove, are provided with rotating ring 6 in the groove.
Described quiet assembly 7 comprises stationary ring, described stationary ring adopts pressureless sintering silicon carbide, it is light to have material weight, the intensity height, the friction ratio number is little, and radiation resistance is good, and self-enrichment, group is good to performance, and characteristics such as chemical stability and heat resistance and heat-conductive characteristic excellence can improve the resistance to flexure and the heat conductivity of friction pair.
Described stationary ring arranged outside has first protective gear; the inboard is provided with second protective gear, as preferably, described in first protective gear of arranged outside be rubber ring 15; described rubber ring 15 is through vulcanizing treatment, and inboard second protective gear that is provided with is set to stainless steel coil 16.As preferably, its end face planeness of described stationary ring is not more than 0.0009mm; Roughness is not more than 0.2 μ m, because pressureless sintering silicon carbide has the hardness height, the big characteristics of fragility are so at periphery bag one circle vulcanized rubber, the inboard is provided with stainless steel coil can strengthen its mechanical shock resistance.
