Title:
PULLEY GROUP AND POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2018123884
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique capable of making an inter-axis distance between pulleys small for a power transmission mechanism comprising a plurality of pulleys provided to have their axes in parallel with each other and a power transmission member extended between and wound around outer peripheral surface sides of those pulleys.SOLUTION: A first pulley 1 comprises at least one first large-diameter part 12 and at least one first small-diameter part 13. The second pulley 2 comprises a second small-diameter part 23 formed at a position corresponding to the first large-diameter part 12 and a second large-diameter part 22 formed at a position corresponding to the first small-diameter part 13. The second large-diameter part 22 is formed small enough not to come into contact with the first small-diameter part 13 and the second small-diameter part 23 is formed small enough not to come into contact with the first large-diameter part 12, with the first pulley 1 and second pulley 2 arranged such that a distance between a first axis C1 and a second axis C2 is smaller than the sum of a maximum radius of the first large-diameter part 12 and a maximum radius of the second large-diameter part 22.SELECTED DRAWING: Figure 3
