Abstract

Official abstract text for this publication.

A gear coupling device and a gear coupling method reduce a vibration and noise caused at the time of engagement of gears. The gear coupling device transmits power through the engagement of the gears and uncouples the gears from each other by causing at least one of the gears to move in an axial direction of the gear. A determining section determines, on the basis of signals detected by rotation sensors, whether or not an end surface of a tooth of the axially moving gear lies between an end surface of a first tooth of the other gear and an end surface of a second tooth of the other gear. A driving section causes the gear to move in the axial direction on the basis of the determination result of the determining section and causes the gears to be coupled to each other.

First claim

Opening claim text (preview).

What is claimed is: 1. A gear coupling device comprising: two gears, that are engaged with each other for power transmission, and that are uncoupled from each other when at least one of the gears axially moves; a plurality of rotation sensors configured to detect rotations of the gears; and a determining section configured to determine, on the basis of signals detected by the rotation sensors, whether or not an end surface of a tooth of the axially moving gear lies between an…
