A cam shaft assembly including a shaft defining a shaft longitudinal axis. The cam shaft assembly further including a gear attached to and extending radially about the shaft. The cam shaft assembly further including a cam attached to the shaft. The cam and the shaft are formed of a single contiguous piece of material. In an embodiment, the gear, the cam and the shaft may all be formed of a single contiguous piece of material. In another embodiment the cam and the shaft are formed of a first material and the gear is formed of a second material.

A carrier assembly for canisters of a mechanical exfoliation apparatus, the carrier assembly including a hub having an external surface and an open center therethrough with an internal surface, at least two bearings mounted on the internal surface of the hub, and a canister cradle integrally extending from the external surface of the hub.

A speed reduction apparatus supports a third crown gear that undergoes wave motion. The speed reduction apparatus includes: a first crown gear; a second crown gear; a third crown gear having opposing teeth facing the first crown gear and opposing teeth facing the second crown gear, back to back; and cam units and that cause the third crown gear to undergo wave motion. The cam units and have a first cam on the first crown gear side with respect to the third crown gear, and a second cam on the second crown gear side with respect to the third crown gear. The first and second cams sandwich the third crown gear. A first rolling element between the first cam and the third crown gear is capable of rolling motion, and a second rolling element between the second cam and the third crown gear is capable of rolling motion.

A device for producing a functional shaft and a functional shaft are provided in which a functional element which is provided with a pocket is inserted into a retaining element, a shaft is inserted into the pocket, and a force applied to the functional element while the shaft is being inserted into the pocket is measured.

A driving apparatus 100 includes a motor 20 that generates drive power and power transmission units 30, 40, and 50 that transmit drive power of the motor 20 to an output shaft 60. The power transmission units 30, 40, and 50 include a brake mechanism 40 that brakes rotation of the output shaft 60 and a deceleration mechanism 50 that converts a torque of the motor 20, and transmits a resultant to the output shaft 60, and the brake mechanism 40 is arranged at a part before the deceleration mechanism 50, and the deceleration mechanism 50 is arranged at a part before the output shaft 60.

A cam device includes a cam and a driver. The cam includes a cam face that is gradually distanced from a rotation center of the cam over a range greater than half a round of the cam. The driver rotates the cam in a first direction and in a second direction opposite the first direction.
