Title:
PHASE ADJUSTMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/1996/036489
Kind Code:
A1
Abstract:
A phase adjustment unit (100) for effecting phase adjustment between rolls of a multi-color printing press comprises a phase adjustment gear device (10) and a phase adjustment motor (6) fitted to the rear end of the gear device (10). The phase adjustment gear device (10) includes a hollow input shaft (12) inside a hollow casing (11) and an output shaft (14) inside the input shaft (12), and spline shafts (121, 141) for fitting are disposed at the distal ends of these shafts (12, 14). Cup type first and second wave motion gear devices (16, 25) are coaxially disposed at the rear end of the spline shafts, and input rotation returns to the first wave motion gear device (16) from an inner gear (161) of the first wave motion gear device through a gear train (30) and the second wave motion gear device (25), and is transmitted to the output shaft (14). While the motor (6) is locked, each constituent element of the first wave motion gear device rotates integrally, and the input and output shafts rotate in the same way. At the time of phase adjustment, the rotation speed of the motor (6) is drastically reduced and outputted through the gear devices (25, 16). Since the input and output shafts protrude from one of the sides, fitting and removal of the unit can be conducted easily.
