Abstract: The present invention relates to a ring gear and a gear reduction device. The ring gear includes an annular body with a plurality of mounting portions, and a plurality of teeth arranged on an inner circumferential surface of the annular body. The annular body and the teeth are integrally formed from powder metal, and the mounting portions and the teeth are at least partly overlapped in an axial direction of the annular body. The mounting portions are integrally formed with the annular body and the teeth, which results in concentricity between the mounting portion and the teeth being improved and cost of the ring gear being reduced. Furthermore, the mounting portions are overlapped with the teeth, which reduces the axial size of the ring gear.

Abstract: A driving device includes a motor and a gearbox. The gearbox includes a first sun gear, first planetary gears surrounding and engaged with the first sun gear, and a first internal gear ring surrounding and engaged with the first planetary gears. The first sun gear is coaxially fixed to a rotary shaft of the motor. Meshing planes of the first sun gear and the first planetary gears are slanted with respect to the rotary shaft.

Abstract: A load connecting mechanism includes a mounting portion, a contact portion, and a force-exerting portion. The mounting portion is configured to mount the load connecting mechanism to a power source and a load, respectively. The contact portion is disposed on the mounting portion and includes two slidably coupled contact faces. The force-exerting portion is configured to provide a force to the contact faces in an axial direction of the power source to make the contact faces closely slidably couple to each other. Through the slidable coupling relationship between the contact faces, power of the power source is progressively transmitted to the load and finally drives the load to rotate in synchronization with the power source. The present invention further provides a motor driving assembly and a fan. The mechanism can satisfy the needs of bidirectional rotation of a load such as a fan and of large startup torque.
