Abstract
A device for retaining a pair of bearing cups on opposing trunnions on a universal joint cross includes a pair of snap rings and a bearing retainer strap. The snap rings each have an outwardly extending portion formed therein and the bearing strap has groove engaging portions formed at opposite ends thereof by folding over the ends of the strap. The groove engaging portions extend into annular grooves formed in the outer surfaces of the bearing cups. The retaining rings are then inserted into the grooves and the outwardly extending portions engage the ends of the strap to maintain the groove engaging portions in the grooves. The strap is formed with a predetermined length corresponding to a desired spacing between the bearing cups.
Claims6
An apparatus for retaining a pair of bearing cups on opposed trunnions of a universal joint cross, each of the bearing cups having an annular groove formed in an outer surface thereof, comprising:
- a pair of snap rings each having a semi-circular body portion with an outwardly extending portion formed therein;
- and
- a bearing retainer strap having an elongated body of a predetermined length with a groove engaging portion formed at each end thereof, each said end being folded over upon said body to form said groove engaging portions adapted to extend into and engage the annular groove formed in an outer surface of a bearing cup and said outwardly extending portion of said snap rings adapted to abut opposite ends of said bearing retainer strap and maintain said groove engaging portions of said bearing retainer strap in the grooves formed in the bearing cups.
An apparatus for retaining a pair of bearing cups on opposed trunnions of a universal joint cross, comprising:
- a pair of snap rings each formed with a semi-circular body having an outwardly extending central portion;
- and
- a bearing retainer strap of generally rectangular cross-section including an elongated body of a predetermined length terminating in opposed ends, each said end folded over upon said body to form a groove engaging portion adapted to extend into and engage an annular groove formed in an outer surface of a bearing cup and maintain a pair of bearing cups in spaced relationship on opposed trunnions of a universal joint cross when said snap rings engage the annular grooves with said central portions abutting said opposite ends of said bearing retainer strap.
A universal joint assembly comprising:
- a universal joint cross having at least two opposed trunnions;
- a pair of bearing cups each engaging one of said trunnions and having an annular groove formed in an outer surface thereof;
- a bearing retainer strap having an elongated body of a predetermined length with opposed ends, each said end being folded over upon said elongated body to form a groove engaging portion extending into and engaging an associated one of said grooves;
- and
- a pair of snap rings each having a semi-circular body with an outwardly extending central portion, said snap rings engaging said annular grooves with said central portions abutting an associated one of said opposed ends to maintain said groove engaging portions in said grooves and said bearing cups in a spaced relationship.
