Abstract
The utility model relates to an alignment with moving axis carries out the sealing device that seals. Directly move epaxial sealing flange including installing, having one section installation step respectively on the inner circumference of sealing flange front and back both sides, forming the arrangement space of sealing member between the periphery of installation step and straight moving axis, the sealing member includes sealing washer, nylon cover and spacing ring, following the introversive outer cover of installing respectively in the arrangement space and directly moving epaxial sealing washer and nylon cover, the spacing ring is put in to nylon, the medial surface of sealing washer is provided with annular oil storage tank, between nylon cover and the spacing ring to and the branch maybe interference fit between the inner circumference of spacing ring and sealing flange, clearance fit between the periphery of nylon cover and straight moving axis. Compare with traditional sealing washer, the utility model discloses have good lubrication and sealed effect.
Description
Technical field
The utility model relates to the seal arrangement sealed direct acting axle.
Background technique
In prior art, for the sealing of direct acting axle, directly adopt seal ring sealing, in the movement process of direct acting axle, seal ring is easily out of shape, sealing and lubrication effect poor.Usually need to change seal ring, add manpower and cost.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of direct acting shaft sealer direct acting axle to excellent sealing effect.
A kind of direct acting shaft sealer of the present utility model, comprises the sealing flange be arranged on direct acting axle, is the junction surface for being connected with cover plate on front side of described sealing flange, this junction surface is provided with the groove of annular, is provided with seal ring in described groove; Before and after described sealing flange both sides inner peripheral surface on there is section of installation step respectively, form the accommodation space of Sealing between the circumferential surface of described installation step and direct acting axle;
Described Sealing comprises seal ring, nylon jacket and limited ring; From inside to outside be separately installed with in described accommodation space and be enclosed within seal ring on direct acting axle and nylon jacket, described nylon jacket overlaps restraining position ring block, and the outside of described limited ring has carries out spacing spacing edge to nylon jacket; The inner side surface of described seal ring is provided with the oil storage tank of annular;
Between described nylon jacket and limited ring, and be interference fit respectively between limited ring and the inner peripheral surface of sealing flange; Spielpassung between the circumferential surface of described nylon jacket and direct acting axle.
Compared with traditional seal ring, the utility model has good lubrication and sealing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the partial enlarged drawing in Fig. 1.
Embodiment
As shown in the figure: a kind of direct acting shaft sealer, comprising the sealing flange 2 be arranged on direct acting axle 1, is the junction surface 3 for being connected with cover plate on front side of described sealing flange 2, this junction surface is provided with the groove of annular, is provided with seal ring 4 in described groove; Before and after described sealing flange 2 both sides inner peripheral surface on there is section of installation step respectively, form the accommodation space of Sealing between the circumferential surface of described installation step and direct acting axle 1;
Described Sealing comprises seal ring 5, nylon jacket 7 and limited ring 8; From inside to outside be separately installed with in described accommodation space and be enclosed within seal ring 5 on direct acting axle 1 and nylon jacket 7, described nylon jacket 7 overlaps restraining position ring block 8, and the outside of described nylon jacket 7 and limited ring 8 is respectively arranged with the step 10 and spacing edge 9 that cooperatively interact; The inner side surface of described seal ring 5 is provided with the oil storage tank 6 of annular;
Between described nylon jacket 7 and limited ring 8, and be interference fit respectively between the inner peripheral surface of limited ring 8 and sealing flange 2; Spielpassung between described nylon jacket 7 and the circumferential surface of direct acting axle 1.
When direct acting axle 1 moves, produce certain extruding to seal ring 5, oil storage tank 6 is squeezed, and then realizes lubricant oil or lubricating grease to the lubrication of direct acting axle 1, and meanwhile, Sealing of the present utility model has good sealing effect.
