Abstract
The utility model discloses a combined sealing structure for ends of rollers, which can meet the requirements of high-speed rotating shafts and can guarantee the sealing effect to the maximum extent. The combined sealing structure comprises a labyrinth component and a lip-shaped sealing piece, wherein the labyrinth component consists of two labyrinth sealing pieces which are matched with each other; the lip-shaped sealing piece is arranged in a cavity formed by the two labyrinth sealing pieces; and the labyrinth component comprises a first labyrinth component and a second labyrinth component which are respectively arranged on the inner side and the outer side of a roller. By combining the labyrinth component and the lip-shaped sealing piece, the combined sealing structure for ends of rollers can form labyrinth sealing and static sealing; and the combined sealing structure is simple in structure and has a better sealing effect than that of a single sealing structure.
Description
Technical field
The utility model relates to a kind of roller class end combined sealing structure.
Background technique
The lubricated requirement of some its bearing of roller class of the low-speed running of the roller class that runs up of machinery or the accurate running of requirement is all higher, therefore the requirement of its sealing also can be corresponding higher, the shaft seal of high-speed rotary machinery is widely used contactless labyrinth seal, the effect quality of labyrinth seal is decided by the complexity of its passage and narrow, and owing to be subject to the restriction of axle head physical dimension, complexity and the stenosis of employed labyrinth seal are limited, and therefore the simple using effect of labyrinth seal of using is also limited.
The model utility content
For the problems referred to above, the roller class end combined sealing structure that the utility model provides a kind of labyrinth seal and static seal to be used in combination.
For achieving the above object, the utility model roller class end combined sealing structure, comprise labyrinth assembly and lip packing, described labyrinth assembly is comprised of two labyrinth seals of installing that cooperatively interact, and described lip packing is arranged in the cavity of described two labyrinth seals formation.
Further, described labyrinth assembly comprises the first labyrinth assembly and the second labyrinth assembly that is installed in respectively the inside and outside both sides of roller.
Particularly, described the first labyrinth assembly is comprised of moving labyrinth and the quiet labyrinth of installing that cooperatively interact, and described moving labyrinth is installed on the roll neck of roller spare, and described quiet labyrinth is installed on the roller case.
Particularly, described the second labyrinth assembly is comprised of moving labyrinth end cap and the quiet labyrinth end cap of installing that cooperatively interact, and described moving labyrinth end cap is installed on the roll neck of roller spare, and described quiet labyrinth end cap is installed on the roller case.
Further, described quiet labyrinth is installed on the described roller case by quiet labyrinth fastening piece.
Further, described quiet labyrinth end cap is installed on the described roller case by quiet labyrinth end cap fastening piece.
Further, described moving labyrinth end cap is fixed on the described roll neck by gland.
The utility model roller class end combined sealing structure, the combined sealing structure that is combined to form labyrinth seal and static seal by labyrinth assembly and lip packing, this composite structure is simple, sealing effect is more effective than adopting single sealing configuration, the accuracy of manufacturing of this structure requires relatively low, can save cost, it is more convenient than a kind of sealing of single use to install and dismantle, and increases work efficiency.Because the life cycle in moving labyrinth is long, do not need to change, according to the cycle that determines to change sealing working life in quiet labyrinth.The use of this structure both can solve the needs of high-speed rotating shaft, also can farthest guarantee the effect that seals simultaneously.

Embodiment
Below in conjunction with Figure of description the utility model is further described.
Roller base part combination combined sealing structure described in the utility model, can make the lubricating component of this roller base part obtain maximum sealing effect, labyrinth seal assemblies can guarantee the basic sealing of the roller base part that runs up for a long time, but can not realize the blocking-up on the complete meaning, realize this blocking-up by static seal, both cooperatively interact and realize the combination seal of such roller based part, thereby the lubrication effect of this roller base part is guaranteed.
Shown in Fig. 1-7, the utility model roller class end combined sealing structure, comprise labyrinth assembly and lip packing 3, described labyrinth assembly is comprised of two labyrinth seals of installing that cooperatively interact, and described lip packing is arranged in the cavity of described two labyrinth seals formation.
Further, described labyrinth assembly comprises the first labyrinth assembly and the second labyrinth assembly that is installed in respectively the inside and outside both sides of roller.
Particularly, described the first labyrinth assembly is comprised of moving labyrinth 11 and the quiet labyrinth 12 of installing that cooperatively interact, and described moving labyrinth is installed on the roll neck of roller spare 1, and described quiet labyrinth is installed on the roller case 2.
Particularly, described the second labyrinth assembly is comprised of moving labyrinth end cap 21 and the quiet labyrinth end cap 22 of installing that cooperatively interact, and described moving labyrinth end cap is installed on the roll neck of roller spare, and described quiet labyrinth end cap is installed on the roller case.
Further, described quiet labyrinth is installed on the described roller case by quiet labyrinth fastening piece.
Further, described quiet labyrinth end cap is installed on the described roller case by quiet labyrinth end cap fastening piece.
Further, described moving labyrinth end cap is fixed on the described roll neck by gland.
The inboard moving labyrinth of roll neck cooperates the processing after heat to be loaded on the roll neck with roll neck, quiet labyrinth is installed on the roller case with fastening piece, and the cavity design and installation lip seal that forms between moving labyrinth and the quiet labyrinth forms labyrinth seal between moving labyrinth and the quiet labyrinth.The sealing of the lubricant oil of the bearing of installing in the roller case is finished by lip seal and labyrinth seal combination seal.
Quiet labyrinth, roll neck outside end cap is installed on the roller case with fastening piece, cooperating processing with roll neck after, moving labyrinth end cap is installed on the roll neck, and fixed by gland 5, the cavity design and installation lip seal that forms between moving labyrinth end cap and the quiet labyrinth end cap forms labyrinth seal between moving labyrinth end cap and the quiet labyrinth end cap.The sealing of the lubricant oil of the bearing 4 of installing in the roller case is finished by lip seal and labyrinth seal combination seal.
For reaching requirement behind the labyrinth size requirement between satisfied moving labyrinth and the quiet labyrinth and moving labyrinth and the roller hot charging, requirement cooperates processing with roller when the moving labyrinth of processing.
Roller class of the present utility model end combination sealing arrangement adopts simple and practical structural type; can be widely used in the lubrication and seal of the roller type component that runs up; this structural type is economic and practical; adopt combination seal greatly to improve the reliability of its sealing; than simple the effective of a kind of sealing that use, when static seal lost efficacy, also has the protection of motive sealing; it is lubricated that bearing can not lost because of the inefficacy of static seal, thereby cause scaling loss.The maintenance of this combination seal is also comparatively easy, because the long service life in moving labyrinth, so only need to consider in actual use the working life of static seal, lost efficacy the needed repair time thereby saved because of lubrication and seal, improve the working efficiency of working machine, also created preferably economic benefit.
