Abstract
The utility model discloses a sine curve-shaped backflow line oil seal, which comprises a rubber body, a frame, a spring, backflow lines and an oil seal lip. The backflow lines on the oil seal lip are sine curve-shaped. The sine curve-shaped backflow lines on the oil seal lip are completely consistent with each other in line shape. According to the utility model, the oil seal lip is provided with sine curve-shaped backflow lines through the shaping of a machining center, thus is suitable for being used in bidirectional rotation conditions. Meanwhile, the oil seal is long in service life.
Description
Technical field
The utility model belongs to the oil seal technique field, especially relates to a kind of sinusoidal backflow line oil sealing.
Background technique
At present in the oil sealing field; The oil sealing of especially two-way rotary seal is an Eight characters backflow line, though such oil sealing does not have the length of backflow line working life greatly; Self does not have the little relatively of backflow line with the wearing and tearing of axle; But the wearing and tearing of oil sealing are still comparatively serious, simultaneously because the restriction of its structure can not be satisfied the requirement of some specific sealing oil sealings.
Summary of the invention
The purpose of the utility model is to improve the deficiency of prior art and provides a kind of lip to adopt the sinusoidal backflow line oil sealing of machining center shaping sinusoidal curve backflow line, suitable two-way rotating environment, long service life.
The purpose of the utility model is achieved in that a kind of sinusoidal backflow line oil sealing, is made up of rubber body, skeleton, spring, backflow line and oil seal lip, is characterized in that the backflow line on the oil seal lip is the sinusoidal curvilinerar figure.
In order further to realize the purpose of the utility model, can be that the line shape of all sinusoidal curvilinerar figure backflow lines on the described oil seal lip is in full accord.
Compared with present technology the utility model has following distinguishing feature and good effect: it is sinusoidal that the utility model adopts the backflow line on the oil seal lip, and sinusoidal backflow line can let the oil sealing medium and the part of touching that is coupling form oil film more fully, bigger reduction oil sealing wearing and tearing; Be suitable for the environment of two-way rotation, because its backflow line is to protrude from oil seal lip portion, so when playing the backflow effect; Can realize good selflubricating; Reduce the wearing and tearing of itself, simultaneously owing on lip, being provided with many group sinusoidal backflow lines, so the sense of rotation of the no optical axis; Can play the effect of backflow; When playing the backflow effect, can realize good selflubricating, reduce the wearing and tearing of itself; The line shape of all sinusoidal curvilinerar figure backflow lines is in full accord on the oil seal lip, has guaranteed that the conformity of sinusoidal backflow line is high, can act on the oil sealing of any structure.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
Embodiment 1; A kind of sinusoidal backflow line oil sealing with reference to Fig. 1, is to be wrapped with rubber body 1 at skeleton 2; Oil seal lip 5 outsides that form in rubber body 1 are provided with spring 3; On oil seal lip 5, be processed with the backflow line 4 of protrusion, the backflow line 4 on the oil seal lip 5 is a sinusoidal, and this constitutes a kind of structure of the utility model.
Claims (2)
1. a sinusoidal backflow line oil sealing is made up of rubber body (1), skeleton (2), spring (3), backflow line (4) and oil seal lip (5), it is characterized in that the backflow line (4) on the oil seal lip (5) is the sinusoidal curvilinerar figure.
2. a kind of sinusoidal backflow line oil sealing according to claim 1 is characterized in that the line shape of last all the sinusoidal curvilinerar figure backflow lines (4) of described oil seal lip (5) is in full accord.
