Japanese Patent JPWO2022185416
Kind Code:
A1
Abstract:
Provided is a transmission for which the calculation accuracy of the rotation angle of second teeth can be improved. The transmission comprises: a plurality of idle gears disposed on a first shaft (12) and provided with first teeth (33); a plurality of movable members (37) disposed on the first shaft so as to be inhibited from relatively rotating and to be movable in the axial direction and provided with second teeth (38) meshed with the first teeth; a fixed gear disposed on a second shaft (13) and meshed with each of the idle gears; a sensor which directly or indirectly detects the rotation of the first teeth and the second teeth; and a control device (60) which acquires positions of the first teeth and the second teeth in a rotation direction on the basis of the detection by the sensor and which starts to move the movable members in the axial direction. The first shaft includes a mark (58) rotated integrally with the first shaft, and the position of the second teeth in the rotation direction has a fixed relationship with respect to the position of the mark in the rotation direction.
