ABSTRACT:
A cargo roller system (10) having drive rollers (13) and idler rollers (19) mounted in a tray (14) and selectively engageable with a motor (30) through a gear train (44). The motor (30) engages the gear train (44) through an idler gear (48) mounted in a motor mount (32) and a driven gear (50) mounted to the shaft (52) of the gear train (44). Coupling assemblies (60) connect the two halves of the gear train (44) to the driven gear (50). The coupling assembly (60) comprises a shaft (52) having a cylindrical piston (62) formed on one end thereof and a cylinder (66) slidably receiving the piston (62) on the other end thereof. A V-shaped opening (70) in the outer wall (72) of the cylinder (66) cooperates with a retaining pin (74) passing through the piston (62) translationally moving the gear train (44) into engagement with the rollers as the cylinder (66) is rotated by the motor (30).
