| 20120060647 | GEAR DEVICE AND METHOD OF MANUFACTURING SHAFT MEMBER - A gear device which has a shaft member including a gear portion and a shaft portion formed consecutively and integrally with the gear portion; and a fitting member that may be fitted into the shaft portion of the shaft member, wherein, in the shaft member, at least the gear portion may be formed by a plastic working, a guard portion protruding from a addendum circle of the gear portion to an outer side in the radial direction may be formed in an end portion of a shaft portion side of an axial direction of the gear portion, and the movement in the axial direction of the fitting member may be restricted by the guard portion. | 03-15-2012 |
| 20120247267 | Process And Apparatus For Installing Original Drive Gear On A Laser Printer Toner Cartridge Drum - A method is disclosed. The method provides an assembly that contains a first drum-cylinder having an inner periphery surface and a drive gear assembly, wherein a portion of the drive gear assembly is in contact with the inner periphery surface, separates the drive gear assembly from the first drum-cylinder, inserts the portion of the drive gear assembly into a second drum-cylinder, and couples the drive gear assembly to the second drum-cylinder. | 10-04-2012 |
| 20090056497 | Rotation Tool - A downhole rotation tool comprises a housing rotatable and axially slideable in relation to a gear shaft. The gear shaft is located interior of the housing. A tube gear is located intermediate the gear shaft and the housing. Helical threading on the gear shaft exterior interacts with helical threading interior of the tube gear to impart rotation of the tube gear upon linear movement of the gear shaft. A gear face at a lower end of the tube gear interacts with a corresponding gear face on the housing. Face gear teeth of the tube gear and the housing include axially-aligned engaging surfaces to rotate the housing in a preferred direction on downward stroke of the gear shaft and include inclined slip surfaces to allow relative rotation of the housing gear face and the tube gear face upon upward stroke of the gear shaft. | 03-05-2009 |
| 20090064818 | HOBBY SERVO ADAPTER - Embodiments of hobby servo motor devices are disclosed. Embodiments include a hobby servo motor having a rotatable splined output shaft and a rotational enhancement mechanism that is rotatably engaged to the hobby servo motor splined output shaft. The rotational enhancement mechanism has an auxiliary shaft that is in-line with the hobby servo motor output shaft. Embodiments also include a support panel that is rigidly connected to the hobby servo motor and displaced from the hobby servo motor. The support panel has an aperture that receives and supports the auxiliary shaft. | 03-12-2009 |
