Abstract
The utility model relates to a rubber oil seal which is used for rotary sealing in a low-voltage oil lubrication system. The rubber oil seal is provided with a framework 1, a rubber layer 2 and a self-tightening spring 5, which is characterized in that the inner edge at the right part of the oil seal is provided with a thread-shaped oil return chute 6, the inner edge at the left part of the oil seal is provided with a dust-proof tongue 7, and a sealing ring 8 is arranged between the dust-proof tongue 7 and the oil return chute 6. The utility model has the function of automatic returning oil and can efficiently prevent the external leakage of the lubricating oil, and the utility model solves the problem of oil leakage of the existing oil seal.
Description
The utility model relates to a kind of rubber oil sea of using do rotary seal in the low pressure oil lubrication system.
Existing rubber oil sea comprises domestic and imported, belongs to the structure shown in the accompanying drawing 1 basically, is made up of skeleton 1, rubber layer 2, dustproof tongue 3, self-tightening spring 5, sealed tongue 4.The just material of import is relatively good, sealed precision is higher, but has grown service time, also exists oil leakage phenomenon.Homemade leakage of oil is even more serious.For head it off, some production of machinery producer near the oil sealing position of rotatingshaft surface Machining oil-return groove, oil leakage phenomenon is greatly alleviated.But at get on the bus system oil-return groove of rotatingshaft is to be cost with the intensity that reduces axle, moreover has increased manufacturing procedure and cost of production.
The purpose of this utility model is to disclose a kind of rubber oil sea that can have the automatic oil return effect.
Technical solution of the present utility model is: a kind of rubber oil sea, have skeleton 1, rubber layer 2, self-tightening spring 5, dustproof tongue 7, and its special way is to be shaped on shape of threads oil-return groove 6 at oil sealing right part inner edge.
The utility model technical solution can be provided with seal ring [8] between dustproof tongue 7 and oil-return groove 6.
Rubber oil sea of the present utility model, owing to be shaped on shape of threads oil-return groove 6, it has the automatic oil return effect, can prevent leaking outside of lubricant oil effectively, has solved the difficult problem of existing oil sealing leakage of oil.
Accompanying drawing 1 is the structural drawing of existing oil sealing.
Accompanying drawing 2 is the structural drawing of the utility model oil sealing.
Embodiment as shown in Figure 2, by skeleton 1, wrapping skeleton 1 rubber layer 2, be located at the dustproof tongue 7 on oil sealing inner chamber right side, be enclosed within dustproof tongue 7 peripheries self-tightening spring 5, be located at the shape of threads oil-return groove 6 of oil sealing right part inner edge and the seal ring 8 that is located between dustproof tongue 7 and the oil-return groove 6 is formed.This oil sealing not only can be made oil sealing and use, and also can do water seal and use.
Claims (3)
1, a kind of rubber oil sea has skeleton [1], rubber layer [2], and self-tightening spring [5], dustproof tongue [7] is characterized in that oil sealing right part inner edge is shaped on shape of threads oil-return groove [6].
2, a kind of rubber oil sea according to claim 1 is characterized in that dustproof tongue [7] is arranged on the oil sealing left part inner edge outside.
3, a kind of rubber oil sea according to claim 1 and 2 is characterized in that being provided with seal ring [8] between dustproof tongue [7] and oil-return groove [6].
