Title:
DRIVING FORCE TRANSMISSION MECHANISM AND LIFTING MECHANISM USING THE SAME AND STANDING-UP AUXILIARY DEVICE
Document Type and Number:
Japanese Patent JP2019143771
Kind Code:
A
Abstract:
To provide a driving force transmission mechanism by a traction drive which is easy to be assembled and a lifting mechanism using the same, and a standing-up auxiliary device.SOLUTION: A driving force transmission mechanism 1 includes first and second rotating bodies 4, 5 in which power is transmitted by a traction drive from one to the other. The first rotating body 4 includes first and second truncated cone parts 8, 9 connected mutually and constituting an annular V-groove 10 by side surfaces 7 of both, and a bolt 13 for connecting the cone parts so that upper bottom surfaces 6 of both oppose to each other with an arbitrary gap. The second rotating body 5 includes an annular protrusion part 17 corresponding to the annular V-groove 10. The traction drive is performed by a traction force generated between the annular V-groove 10 and the annular protrusion part 17.SELECTED DRAWING: Figure 1
