A dust boot for a universal joint covering two joint elements having largely curved corner portions in the outer peripheral surface thereof near their joint portion, comprises a resilient annular covering portion for covering the joint portion of the universal joint and two annular end portions which are integrally formed with the covering portion in axially both ends thereof. The annular end portions are mounted on the two joint elements near their joint portion. Since the area of an open end of the dust boot mounted on the joint element having largely curved corner portions is made smaller than the cross sectional area of the outer peripheral surface of the joint element, specifically only the curvature of the open end of the dust boot corresponding to the largely curved corner portions of the joint element is made smaller than that of the corner portions of the joint element, the dust boot can be closely mounted on the joint element with excellent sealing effect.
A universal joint sealing assembly comprised of two joint elements where at least one of said joint elements has a housing with an outer peripheral surface which includes a plurality of straight, curved and corner portions with the corner portiosn having a greater curvature than that of the other portions,
A universal joint seal assembly for enclosing a universal housing, said assembly comprising an annular cover having two axially aligned ends each having means defining an opening at the end, at least one end having a plurality of straight, curved and corner portions for fitting over a like plurality of straight, curved and corner portions on said universal joint housing, wherein each corner portion included within said open means has a radius of curvature smaller than the complementary radius of curvature of the corner portion of said housing over which it will fit with the remaining portions of said opening means extending between the corner portions being shaped to substantially correspond to the complementary portions of said housing extending between the corner portions thereof and clamping means for clamping said at least one end onto said universal joint housing.
A dust boot for covering a universal joint for coupling together first and a second joint elements, said second joint element having corner portions on an outer peripheral surface thereof comprising:
A dust boot for covering a universal joint which has at least one corner portion and a straight portion on the outer peripheral surface of said joint, comprising:
A dust boot for enclosing a universal joint housing, said dust boot having means defining an opening at one end and having at least one curved portion for fitting over at least one complementary curved portion on said housing, wherein each radius of curvature included within said opening means has a radius of curvature smaller than the complementary radius of curvature over which it will fit on the outer peripheral surface of said housing.
