Mounting device and method for positioning a motor within an image forming apparatus
The application includes various embodiments of devices and methods for mounting a motor within an image forming apparatus. The motor is mounted on a frame and positioned to engage and drive a component within the image forming apparatus. In one embodiment, the component is an imaging unit. The frame includes an opening to receive the motor. A locating member is attached to the frame and extends into the opening to contact the motor and provide accurate positioning for engagement with the component. The locating ring provides for a press fit with lower forces. Additional fasteners may fixedly connect the motor to the frame and maintain the accurate positioning provided by the locating member.
1. A device to position a motor relative to a frame within an image forming apparatus, the device comprising:
a ring including an inner edge and an opening, the opening dimensioned to provide an interference fit with the motor;
a plurality of contact segments formed on a portion of the inner edge of the ring and protruding from the inner edge towards a centerpoint of the opening to contact the motor, the plurality of contact segments contacting the motor in a manner that a remainder portion of the inner edge is spaced away from the motor;
a plurality of slots formed in the ring and uniformly spaced around the opening to provide slight expansion of the opening when the motor is inserted therein; and
a plurality of cords each of which is formed in the ring between the plurality of slots and the contact segments of the ring, the cords being deformed towards the plurality of slots during insertion of the motor.
2. The device of claim 1 , wherein the plurality of contact segments are substantially straight and positioned on the inner edge of the ring adjacent each of the plurality of slots, the plurality of contact segments being in closer proximity to the centerpoint of the opening than the remainder portion of the inner edge of the ring.
3. The device of claim 1 , wherein the ring includes an outer edge that is substantially parallel with the inner edge.
4. The device of claim 1 , wherein the opening includes the inner edge with first sections that are substantially circular and second sections that are substantially straight.
5. The device of claim 1 , wherein the opening is substantially centered within the ring.
6. The device of claim 1 , wherein at least one of the plurality of slots extends into the opening and includes a cantilevered cord.
7. The device of claim 1 , wherein each of the plurality of slots includes an outer side positioned away from the opening and an inner side positioned towards the opening, the inner side including first and second sections with an angled orientation.
