GEAR APPARATUS AND IMAGE FORMING APPARATUS

摘要

One or more exemplary embodiments provide a gear apparatus. The gear apparatus includes a gear including a shaft hole, a reinforcing member that has a higher stiffness in comparison to the gear, and a rotation shaft that is inserted into the shaft hole through the reinforcing member. In this example, the gear and the reinforcing member are connected such that they rotate together, by a first connecting portion provided at a radial outside of the shaft hole. In this example, the reinforcing member and the rotation shaft are connected to rotate together, by a second connecting portion.

主权项

1. A gear apparatus comprising:
a gear comprising a shaft hole and a gear portion; a rotation shaft that is inserted into the shaft hole; a reinforcing member comprising a through hole into which the rotation shaft is inserted, and that has a stiffness that is higher than a stiffness of the gear; a first hooking portion that is provided at the gear; a first hooked portion that is provided at the reinforcing member and is configured to be engaged with the first hooking portion in a direction of rotation of the gear, such that the reinforcing member and the gear rotate together; a second hooking portion that is provided at the rotation shaft; and a second hooked portion that is provided at the reinforcing member and is configured to be engaged with the second hooking portion in the direction of rotation, such that the reinforcing member and the rotation shaft rotate together.
