Abstract
The utility model relates to an elastic self tightening rubber oil seal which is characterized in that the circumference of a lip opening of an oil seal (3) is wounded with a circle of self tightening springs (4) to perform an oil sealing function. A press plate (1) for sealing the oil is composed of two half circular ring plates, a press ring (2) for sealing the oil which is arranged on the oil seal (3) is pressed in the end surface of the press plate (1) for sealing the oil by the press plate (1), and the oil can not leak form an interface of the press plate (1). The utility model has the advantages of simple structure, low cost, convenient assembly and disassembly, and good oil sealing effect.
Description
The utility model belongs to a class Sealing, is specifically related to a kind of rubber oil sea.
Present existing self-tightening rubber oil sea great majority adopt the integrated type outside framework oil seal, and this oil sealing is owing to be placed with metal frame in it, and its oil sealing integral body is rigidity, and some end of can't packing into has flange to connect in the axle of dish.Existing people adopts the split oil sealing to seal, to adapt to the needs of these special constructions, this oil sealing is generally combined by two semicircle oil sealings, because there is interface the junction of semicircle, and do not have the self-tightening device and can not compensate automatically because of the formed gap of wearing and tearing, to the high speed rotating and the impact load bad adaptability of axle, its elasticity and toughness are all undesirable.Therefore, the oil sealing weak effect, working life is short.
The purpose of this utility model provides a kind of simple in structure, and mounting or dismounting are convenient, the exoskeletal soft self-tightening rubber oil sea that oil sealing is effective.
The technical solution of the utility model is: establish an oil sealing pressure ring on the soft self-tightening oil seal end face of all being made by rubber, by screw it is pressed in the rubber oil sea end face with two semi-annular shape oil sealing pressing plates, the self-tightening spring shackle is around on the oil seal lip circumference.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model A-A sectional view;
Fig. 3 is the utility model oil sealing pressure ring structural drawing.
As shown in Figure 1 and Figure 2, the utility model is made up of oil sealing pressing plate 1, oil sealing pressure ring 2, oil sealing 3, self-tightening spring 4.Oil sealing 3 all adopts rubber to make, because rubber has certain elasticity, can by suitable stretching pack into some end have flange connect dish the axle in, and play the oil sealing effect, rear end as bent axles such as 492Q h type engine h, Dongfeng Automobile motors has the flywheel greater than the bent axle diameter to connect dish, just can adorn soft self-tightening rubber oil sea in this case.Around a circle self-tightening spring 4, under the effect of spring force, can compensate the wearing and tearing of lip voluntarily, thereby oil sealing be effective on the lip circumference of oil sealing 3 tightly around the lip of oil sealing 3; Oil sealing pressing plate 1 is pushed down oil sealing 3 to be screwed on oil sealing base again and (is not drawn among the figure), plays fixed soft body rubber oil sea 3, in case oil sealing rotates with axle, also plays the oil sealing effect simultaneously.Oil sealing pressing plate 1 is made of two semicircle ring flat-plates, be convenient to assembling like this, but there is interface the junction of two plates, easily causes leakage.Therefore, as shown in Figure 3 an oil sealing pressure ring 2 is set between oil sealing pressing plate 1 and oil sealing 3, this ring is formed by a little steel wire or copper wire coiling, and under the effect of oil sealing pressing plate 1, pressure ring 2 is pressed in rubber oil sea 3 end faces, thereby plays the effect of leaking of preventing.As be processed with various difform decorative pattern rib grooves on the conical surface of this oil sealing work lip, making soft self-tightening backflow rubber oil sea effect will be desirable more.
The utility model is simple in structure, and cost is low, and mounting or dismounting are convenient, and oil sealing is effective.
Claims (2)
1, a kind of soft self-tightening rubber oil sea is characterized in that oil sealing (3) all made by rubber, establishes oil sealing pressure ring (2) on its end face, and oil sealing pressing plate (1) is pressed thereon, and self-tightening spring (4) circle is around on oil sealing (3) the lip circumference.
2, soft self-tightening rubber oil sea according to claim 1 is characterized in that described oil sealing pressing plate (1) is made up of two blocks of semi-annular shape plates.
