Abstract
The utility model relates to a sealing device, in particular to a springless oil seal used to seal lubricating grease, which overcomes the defect that the lip of the existing springless oil seal is apt to be reversed during reverse installation. The springless oil seal comprises a main sealing lip and an auxiliary sealing lip. The direction of the lip of the main sealing lip and the direction of the lip of the auxiliary sealing lip are consistent with each other, i.e. face to the bottom of the oil seal. The oil seal at least comprises one auxiliary sealing lip. Through changing the lip pattern of the main sealing lip to enable the main sealing lip not to be apt to be reversed during reverse installation, the utility model has the advantages of convenient assembling and improved sealing effect.
Description
Technical field
The utility model belongs to seal arrangement, relates in particular to a kind of no spring oil sealing that is used for packing grease.
Background technique
The oil seal structure of using always during packing grease as shown in Figure 1, this oil sealing comprises sealing main lip 1, sealing pair lip 2 and skeleton 3, seals main lip 1 and is used for packing grease, and sealing pair lip 2 is dust excluder lips, prevent that outside dust or impurity from entering in the lubricating grease, skeleton 3 supports whole oil sealing.The general mode that adopts forward to install when this oil sealing is installed, when running into special circumstances and need oppositely install, it seals main lip anti-lip easily takes place, and causes oil seal failure.Therefore the oil sealing of this kind structure is not suitable for reverse installation.
Summary of the invention
The defective of easy anti-lip when the purpose of this utility model is that overcoming existing no spring oil sealing oppositely installs by changing the lip form of the main lip of sealing, makes it be difficult for anti-lip when oppositely installing, and is convenient to assembling, and improves sealing effect.
The utility model is to adopt following technological scheme to realize: a kind of no spring oil sealing, comprise sealing main lip and sealing pair lip, wherein, the lip of the main lip of described sealing and the lip of sealing pair lip towards consistent, promptly towards the bottom of oil sealing, and include a sealing pair lip in this oil sealing at least.By changing the structural type of the main lip lip of sealing, this oil sealing can be applicable to reverse installation.
In the utility model, seal the lubricating grease that main lip is used to seal the one side, the sealing pair lip stops introduced contaminants pollution lubricating fat effectively.By increasing the sealing pair lip, can play better dustproof effect on the one hand, can improve the servo-actuated between oil sealing and the running shaft on the other hand, improve sealing effect.
The beneficial effects of the utility model are: at first, when this oil sealing was oppositely installed, its main lip lip anti-lip can not occur, so oil sealing is convenient to assembling, had prolonged working life of oil sealing; In addition, by multiple-sealed secondary lip is set, make the pliability of oil sealing better, the servo-actuated that has improved oil sealing for providing sufficient interference fit between oil sealing and the axle, has guaranteed the sealing effect of oil sealing.
Description of drawings
Fig. 1 is the half sectional view of no spring oil sealing in the prior art;
Half sectional view when Fig. 2 has a sealing pair lip for the utility model;
Half sectional view when Fig. 3 has two sealing pair lips for the utility model.
Embodiment
As shown in Figure 2, this no spring oil sealing comprises sealing main lip 1, sealing pair lip 2 and skeleton 3, is surrounded by rubber body on the skeleton 3.The lip that wherein seals main lip 1 and the lip of sealing pair lip 2 be towards consistent, all towards the bottom of oil sealing.Seal main lip 1 and be used to seal solid-state lubricating grease, sealing pair lip 2 is used to seal introduced contaminants.By changing the structural type of the main lip lip of sealing, make oil sealing be applicable to reverse installation.Skeleton 3 has played the effect of supporting whole oil sealing.
As shown in Figure 3, contain the secondary lip 2 of two seals in this oil sealing,, improved the pliability of oil seal lip, make the servo-actuated of oil sealing better, improved the sealing effect of oil sealing by increasing sealing pair lip 2.In addition, more multiple-sealed secondary lip can also be set in this oil sealing.
Claims (1)
1. no spring oil sealing comprises main lip of sealing and sealing pair lip, it is characterized in that: the main lip lip of described sealing and sealing pair lip lip towards consistent, promptly towards the bottom of oil sealing, and include a sealing pair lip in this oil sealing at least.
