A spherical clearance (δ3) that allows guide in contact is formed between a spherical outer peripheral surface (Rc2) of the inner joint member (3) and a spherical inner peripheral surface (12) of the cage (5). A positive axial clearance is formed between the pocket (5a) of the cage (5) and the torque transmission ball (4).

摘要: A sliding type constant-speed universal joint comprises an outer joint member (1) having eight linear guide grooves (1b) axially formed on a cylindrical-shaped, inner diametrical surface (1a), an inner joint member (2) having eight linear guide grooves axially formed on a spherical-shaped, outer diametrical surface (2a) and serrations (2c), which serve as connecting shaft portions, on an inner diametrical surface, eight torque transmitting balls (3) arranged in ball tracks formed by the guide grooves (1b) of the outer joint member (1) and the guide grooves (2b) of the inner joint member (2) in cooperation with each other, and a retainer (4) for holding the torque transmitting balls (3). The retainer (4) comprises a ring comprising a spherical-shaped outer diametrical surface (4b) adapted to be contacted and guided by the inner diametrical surface (1a) of the outer joint member (1), a spherical-shaped inner diametrical surface (4a) adapted to be contacted and guided by the outer diametrical surface (2a) of the inner joint member (2), and eight pockets (4c) receiving therein the torque transmitting balls (3). The center B of a spherical surface on the outer diametrical surface (4b) and the center A of a spherical surface on the inner diametrical surface (4a) are offset equal distances in opposite directions axially relative the center O of the pockets (4c) (Offset f= line segment OA = line segment OB).
