Abstract
The utility model relates to a mechanical fitting part, in particular to an oil seal. The oil seal comprises an oil seal body, wherein the oil seal body is made of rubber and has a hollow cylindrical structure. The oil seal is characterized in that: one or more ring spring grooves are formed on the outer race of the oil seal body, and ring springs are arranged in the ring spring grooves; and a steel ring layer is arranged within the ring spring grooves in the oil seal body. The oil seal with the structure has the advantages that: the ring springs cannot run out easily, oiliness cannot be accumulated easily, and pollution cannot be caused easily.
Description
Technical field
The utility model relates to mechanical fitting, particularly relates to a kind of oil sealing.
Background technique
Present employed oil sealing has inner ring body and outer ring body, has cirque body to be connected in a side of interior full circle and outer ring body, during use; Ring spring is installed between inner ring body and the outer ring body; Such oil sealing is not because a side is controlled the parts of ring spring, and ring spring is often run out of easily, has awkward shortcoming; In addition because because the one of which side opening has the shortcoming of accumulating greasy dirt easily toward contact.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, provides a kind of ring spring to be difficult for running out of, being difficult for the oil sealing of pollution.
The technological scheme of the utility model is achieved in that a kind of oil sealing; Comprise the oil sealing body, the oil sealing body is that rubber is processed, and described oil sealing body is a hollow cylindrical structure; It is characterized in that: have one or more ring spring grooves in the outer ring of oil sealing body, ring spring is installed in the ring spring groove.
Say that further described oil sealing body interior ring spring groove is with interior steel ring layer in addition.
The beneficial effect of the utility model is: the oil sealing of this spline structure has ring spring and is difficult for running out of, is difficult for containing greasy, as to be difficult for pollution advantage.
