Abstract
The universal joint (10) comprises a first shaft (12) with an annular head (14) having a cavity (16) therein and oppositely disposed seats (17, 19) about the perimeter of the cavity (16). The seats (17, 19) have inclined bottom surfaces (21) which displace radially inwardly a pair of seats (30) each having a cylindrical seat extension (34) terminating in a curved seat surface (38). The second shaft (22) has a head (24) with diametrically opposed recesses (26) each having a curved surface (28) therein. The head (24) of the second shaft (22) is captured between the seats (30) to provide a lash-free universal joint (10).
