Abstract
An improved dual cam indexing drive assembly (10) is disclosed which is well suited for use in driving various types of rotational, linear, and/or reciprocating work transfer apparatus (12). The drive system (10) utilizes primary and secondary rotatable cams (32, 34) supported on and driven by a common shaft (36) coupled to a power source (24) via suitable gear reduction (30), clutch and/or brake means. Aligned primary and secondary cam followers (54, 56, 58 and 64, 66, 68) are provided on the moving transfer apparatus (14), the primary cam followers (54, 56, 58) being designed to operatively engage cam grooves (46, 48) provided on both primary and secondary cams (32, 34) whereas the secondary cam followers (64, 66, 68) cooperate only with cam grooves (48, 50, 52) provided on the secondary cam (34) to drive the work transfer apparatus (12) between successive work stations.
