Title:
POWER TRANSMISSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/193401
Kind Code:
A1
Abstract:
This power transmission mechanism (1) is provided with a first pulley (30) that is fixed to a housing (10) and is driven to rotate around a first axis (L1), a second pulley (40) that is fixed to the housing so as to be separated from and parallel to the first axis, and that is supported so as to be rotatable around a second axis (L2), and a third pulley (50) that is supported between the first axis and the second axis so as to be rotatable around a third axis (L3) which is parallel to the first axis. The third pulley is formed by coaxially fixing a large-diameter pulley (51) that has a greater diameter than the first pulley and a small-diameter pulley (52) that has a smaller diameter than the second pulley; a first belt (60) is looped between the first pulley and the large-diameter pulley; a second belt (61) is looped between the small-diameter pulley and the second pulley; and the third pulley is supported so that the position thereof with respect to the housing can be adjusted, within a first plane (11) that is orthogonal to the third axis, in a direction that intersects a second plane which includes the first axis and the second axis.
