Gear system

Abstract

To provide a gear mechanism that can reduce noise caused by collisions between gears and shaft members. [Solution] The gear device of the embodiment includes a gear 12, a shaft member 13 attached to the gear 12 and rotating about the rotation axis of the gear 12, and a restricting part 31 that restricts the relative movement of the gear 12 and the shaft member 13 in the rotation direction RD of the gear 12 and the shaft member 13. The restricting part 31 has irregularities 122 on the gear 12 in the rotation direction RD and irregularities 132 on the shaft member 13 in the rotation direction RD. The gear device further includes an intervening part 32 that fills the gap G between the irregularities 122 of the gear 12 and the irregularities 132 of the shaft member 13.

Claims

1. Gears and, A shaft member attached to the gear and rotating about the rotation axis of the gear, The system includes a restricting unit that restricts the relative movement of the gear and the shaft member in the rotational direction of the gear and the shaft member, The restricting portion has irregularities on the gear in the rotational direction and irregularities on the shaft member in the rotational direction, A gear apparatus further comprising an intervening component that fills the gap between the irregularities of the gear and the irregularities of the shaft member.

2. The gear apparatus according to claim 1, wherein the intervening component fills the gap between the irregularities of adjacent gears in the rotational direction and the irregularities of the shaft member.

3. The gear apparatus according to claim 1 or claim 2, wherein the intervening component is softer than the gear and the shaft member.

4. The gear apparatus according to claim 3, wherein the intervening component is an elastic body.

5. The gear apparatus according to claim 4, wherein the intervening component is made of an elastic adhesive.
