| 摘要 | A VARIABLE SPEED POSITIVE-DRIVE POWER TRANSMISSION INCLUDES A POWER GROUP OF GEARS AND AT LEAST TWO COUPLING GROUPS, BOTH OF WHICH ARE COUPLED TO THE POWER GROUPS. THE POWER GROUPS EACH INCLUDE A PRIMARY INPUT SHAFT AND AT LEAST TWO OSCILLATORY SHAFTS. THE OSCILLATORY SHAFTS OPERATE WITH PERIODIC SPEED VARIATIONS AND THEREFORE HAVE VARIABLE REDUCTION RATIOS IN RELATIVE TO THE PRIMARY SHAFT OF THE GROUP. EACH COUPLING GROUP HAS A SECONDARY SHAFT AND EACH SECONDARY SHAFT IS COUPLED TO MOTION TRANSFER POINTS OF THE POWER GROUPS. THE TRANSMISSION IS INTENDED FOR USE WITH LATHES AND OTHER MACHINE TOOLS WHERE VARIABLE OSCILLATORY SPEEDS ARE REQUIRED. | ||||||
