装置の同期構造。Among a pair of meshing gears 3.4 fitted on two parallel shafts 1 and 2, one gear 3 is made slidable and the other gear 4
In a gear transmission device that performs gear meshing by engaging and disengaging, a synchronizing gear 6 is arranged in parallel on the side surface of the gear 4 on the gear 3 meshing side, and the tooth profile formed on the outer periphery of the synchronizing gear 6 is The engagement start end is wide, and the outer circumference becomes thicker as it goes to the retention end.Furthermore, the inter-tooth distance t at the engagement end is normal, and the outer circumference is slightly smaller than the outer circumference of the gear 4. A synchronous structure for a gear transmission device, characterized in that the periodic gear 6 is elastically pressed into contact with the side surface of the gear 4 via an elastic body 7.
