Document Type and Number:
Japanese Patent JP2018168901
Kind Code:
A
Abstract:
To simplify a preload structure to downsize a transmission, and perform lubrication for a traction drive for a long term.SOLUTION: A preload mechanism 14 of a compound transmission 1 is configured to set a diameter D1 of a rolling body 11 larger than a distance L1 between a contact point CP1 where the rolling body 11 contacts with a raceway surface 9a of an inner ring 9 and a contact point CP2 where the rolling body 11 contacts with a raceway surface 10a of an outer ring 10. An intermediate shaft 13 of a first transmission mechanism 4 has a power transmission unit rotating in a state of engaging to the rolling body 11, to transmit rotational driving force of an input shaft 2 to the intermediate shaft 13. The power transmission unit is a holder 12 holding the rolling body 11, and the holder 12 includes a flocked part 12c holding lubricant.SELECTED DRAWING: Figure 2
