074437000 | Irregular teeth and bodies | 6 |
20090272214 | Method and apparatus for minimizing variations in the angular velocity of a rotating member - A method and apparatus for altering (minimizing or maximizing) characteristic (angular velocity or torque) variations of a rotating member connected to an engine consisting of a set of engaged circular gears modified in shape as a function of the “wave train signature” of the engine to which the gearset is connected such that the “wave train signature” of the rotating member is essentially “wrapped” around circular gears to form a noncircular gearset that alters the variations of the rotating member. | 11-05-2009 |
20110203397 | GEAR - A gear for use in a power transmission arrangement which has a plurality of split teeth projecting outwardly from a body. Each tooth has a first part and a second part which each project outwardly from the body, each tooth defining a gap between the first part and the second part. Each tooth part includes an interlock formation which corresponds with the interlock formation of the other tooth part to limit relative movement of the tooth parts in use. The invention provides a power transmission arrangement in which backlash is eliminated or reduced, so that the power transmission arrangement operates more quietly than conventional arrangements. | 08-25-2011 |
20120255385 | GEAR DEVICE AND ROTARY ACTUATOR HAVING THE SAME - A gear device includes a drive gear and a driven gear. The drive gear includes first and second toothed portions, which are coaxial with each other. A radius of a pitch circle of teeth of the first toothed portion of the drive gear is different from a radius of a pitch circle of teeth of the second toothed portion of the drive gear. The first and second toothed portions of the drive gear are displaced from each other in a circumferential direction of the drive gear. The driven gear includes a toothed portion, which is meshed with the first toothed portion of the drive gear. | 10-11-2012 |
20120272766 | PIVOT ARM ASSEMBLY FOR SEMICONDUCTOR WAFER HANDLING ROBOTS AND METHOD FOR MAKING THE SAME - A method for making a robot pivot arm assembly includes forming from a rigid, machinable material a circular disk, and forming a circular aperture through the center of the disk. An outer bearing track is formed integrally in the inside surface which defines the aperture, and the apertured disk is positioned in a machining device with a fixturing portion that engages the outer bearing track. An integral outer race, an arm and a gear segment with teeth are then machined into the disk to form the outer portion of the pivot arm assembly. An inner race with an inner bearing track is positioned inside the integral outer race, and rolling bearing elements are inserted into the first and second bearing tracks. | 11-01-2012 |
20130220049 | Method for Producing High-Strength Components by Means of Adiabatic Blanking - The present invention relates to a method for producing a component of an adjustment device for vehicle seats, wherein, in a first step, a work piece is machined such that the work piece is harder in a first region than in a second region, and/or in that the work piece is of a larger geometrical size in a third region than in a fourth region, wherein, in a second step, the work piece is deformed in such a way that a tool is moved onto the work piece at a speed greater than 1 m/s. | 08-29-2013 |
20150047449 | TONER DRUM GEAR PROJECTION - A drivable projection for a toner cartridge drum gear includes an axially extending support portion having a plurality of axially extending edges and an end face. A plurality of substantially spherical engagement portions are supported by the support portion, and each engagement portion defines a center that may be substantially aligned with the end face and/or substantially aligned with a respective one of the plurality of axially extending edges. The engagement portions are configured to receive driving rotatable force from the drive mechanism of a printer. | 02-19-2015 |
