    摘要: A power transmission device includes a drive coupling, a driven coupling, and an intermediate transmission member. The drive coupling receives power from a drive source and rotates. The driven coupling is disposed coaxially on a first rotary shaft of the drive coupling and detachably attachable relative to the main body of the image forming apparatus. The intermediate transmission member meshes with the drive coupling and the driven coupling and is held by one of the drive coupling and the driven coupling in a state in which the driven coupling is disengaged from the main body. One of the drive coupling and the driven coupling, whichever holds the intermediate transmission member, constitutes a retaining coupling including an attachment member attached to one of a drive-side device and a driven-side device, and a stopper assembly facing the intermediate transmission member in an axial direction of the first rotary shaft.

    摘要: A rotary body driver includes a driving source and a planetary gear transmission to receive a driving force from the driving source. The planetary gear transmission includes a sun gear rotatable by the driving force received from the driving source, a plurality of planet gears meshed with and surrounding the sun gear with an identical interval between the adjacent planet gears, a rotatable carrier to rotatably support the plurality of planet gears, an outer gear encircling and meshed with the plurality of planet gears, and an output shaft combined with and supporting the carrier. A rotary body shaft mounting a rotary body is connected to the output shaft of the planetary gear transmission to transmit the driving force received from the output shaft to the rotary body. The outer gear is made of resin and the output shaft and the carrier are made of metal.

    摘要: A rotary drive device to drive a rotary body included in an image forming apparatus. The rotary drive device includes a drive source and a planetary gear mechanism to control torque from the drive source. The planetary gear mechanism includes a sun gear rotated by the torque, an annular gear coaxial to the sun gear and having inward-facing teeth, multiple planetary gears provided within the annular gear, and a carrier rotatable coaxially to the sun gear and the annular gear to rotatably support the multiple planetary gears. The annular gear is formed by injecting molten resin into a mold having a cylindrical cavity with teeth shapes along an inner circumference of the cavity from multiple pin gates provided to the mold at equal intervals along a circumference of the cavity. A number of pin gates is a non-integer multiple of a number of planetary gears.

    摘要: A drive device including a planetary gear reduction device having at least two stages and an output shaft, and a driven shaft to support a driven member rotatively driven by torque reduced by the planetary gear reduction device and transmit the torque from the output shaft to the driven member. Each stage of the planetary gear reduction device includes a sun gear, an outer gear, multiple planetary gears, a carrier, and a support shaft. The output shaft is provided to the carrier of the last stage. Central axes of the sun gear, the outer gear, the carrier, the output shaft, the driven shaft, and the driven member are all arranged coaxially with one another and at least one carrier is floatingly supported relative to the outer gear. The carrier is formed as a single integrated unit having holes into which both ends of the support shaft are fitted.
