Developed in the 1960's, it has been used successfully by OEM and the replacement market worldwide in an extremely wide range of applications. The V-ring is used alone to seal out the ingress of dirt, dust, water or combination of the above media while positively retaining grease. With its unique design and performance the V-ring protects a wide range of bearing types. It is often used as a secondary seal to protect primary seals that do not perform well in hostile environments. V-ring seals are mounted on shafts and their thin, tapered lip seals against a surface (counterface) at right angles to the shaft (fig 86a). No special demands are placed on the surface finish of the shaft seating and the V-rings act as flingers (fig 86b), since they have an interference fit on the shaft and rotate with it. Misalignment of the shaft with respect to the counterface (fig 86c) can be tolerated and V-rings also provide reliable sealing if the shaft is out-of-round or rotates eccentrically (fig 86d). It should be remembered when using V-rings that the amount by which the shaft can be displaced axially is governed by the permissible displacement of the V-ring relative to its counterface. V-rings are made entirely of elastomer without fabric or sheet metal reinforcement. They are, therefore, particularly easy to install. They can be stretched and, depending on size, can be pushed over other components of the arrangement, e.g. flanges, pulleys or even housings. This is a very valuable characteristic, expecially in the case of repairs. Function The V-ring has a body (87a) and a flexible conical shaped sealing lip (87b) with an integral resiliant “hinge” (87c). It is streched and mounted directly on the shaft, where it is held in place by the inherent tension of the seal body. It rotates with the shaft and seals axially against a stationary counterface. The counterface can be the end face of a bearing, a washer, stamping, bearing housing, or even the metal case of an oil seal. In many instances the V-ring can be stretched and installed over flanges and bearing housings without costly dismantling. b a c Fig 86 Fig 87 gab.ru Берг АБ bergab@ya.ru Тел.
