Method of detecting amount of axis displacement in power transmission device using automatic self-aligning engagement clutch

摘要

A method of detecting an amount of an axis displacement in a power transmission device includes, for each of the rotary shafts of the first and second drive sources, measuring an amount of an axis position variation by using non-contact sensors respectively provided to face the rotary shafts, and detecting an amount of a relative axis displacement of the rotary shaft of the second drive source relative to the rotary shaft of the first drive source on the basis of the amount of the axis position variation between before and after engagement.
