ABSTRACT:
A fluid coupling (11) is attached to a pulley (25) attached to an input shaft (35) and a hub (33) having a cylindrical opening. The coupling has an output member (11) and an input member rotatably disposed within a viscous fluid chamber to transmit torque from the input member to the output member in response to relative rotation therebetween. The input member includes a shaft (17) having a boss (47) adjacent the rear surface of the output member. The boss defines a cylindrical extension (49) located within the hub opening. A locking "V" groove (51) is located within the hub opening on the extension. Threaded openings (57) are radially disposed within the hub and have center lines off-set with respect to the center line of the "V" groove when the components are assembled. A set screw (59) in each opening has a frusto-conical surface (61) engaged with an angled surface (63) of the "V" groove to draw the coupling and input shafts together. Radial surfaces (55 and 45) perpendicular to the axis A--A of rotation are located on the boss and hub and aid alignment of and securement of the two members. The boss also includes a pilot opening (53) engaged with the input shaft to aid alignment.
