Abstract: Aspects provide gear set systems that include cylindrical input gear having gear elements arrayed outwardly on a common input gear element radius from a central axis. A sprocket gear disposed about a sprocket pin has teeth disposed to mesh with the cylindrical input gear elements. An output disc body disposed about the cylindrical input gear and attached to the sprocket pin defines circular grooves on a radius from the central axis. Ball bearings are disposed between the output disc body circular grooves and respective grooves formed on a housing, wherein the ball bearings transfer an operational load of the output disc body conveyed through the output disc body circular grooves to the housing while rolling along the circular grooves during operation of the gear set system.

Abstract: A compound gear system and method comprising a flexible gear defining an array of gear elements in an articulating relationship, a rigid structure defining first and second spaced parallel pluralities of articulating gear support structures arrayed in a ring, the articulating gear reeved tightly about and engaging the support structures, thereby restraining the flexible articulating gear from moving inwardly or rotationally relative to the rigid structure while enabling the flexible gear to expand outward, and at least one sprocket gear having a plurality of sprocket teeth aligned to engage flexible gear element middle areas. The support structures transmit torque between the flexible gear elements and the rigid structure responsive to interaction of the flexible gear element middle areas with the sprocket gear teeth.

Abstract: A composite gear member and gear set using the composite gear member is provided. The composite gear member is formed of a generally circular disk having a pair of link plate supporting surfaces separated by a central section. A roller chain which includes a plurality of rollers rotatably mounted on support pins extends between link plates. The chain is reeved around the disk with the link plates being supported in the grooves on the link plate supporting surfaces. Retaining devices in the form of retaining plates or pins are connected between the chain and the disk to restrain circumferential movement of the chain with respect to the disk. This also prevents circumferential slipping of the chain.If the mounting of the chain on the disk is by a retaining plate device engaging the link plate, a single strand of chain is utilized to form the entire gear member, with the second toothed gear being arranged to drivingly engage the rollers.

Abstract: A cycloidal gear device is provided in which rotational input motion is transformed through oscillation of a torque plate in linear direction to a smooth, high torque low speed output. In one embodiment, the device also includes a hollow input shaft, and an output shaft telescoped within the input shaft. The input shaft is journalled on the output shaft to thereby utilize the output shaft on a load support member for the input forces.

Abstract: A hand tool for crimping a work piece by sliding jaw action is provided. The tool has a first handle which fixedly mounts a first jaw at one end thereof and slidably mounts a second jaw in a channel formed therein. A second handle is pivotally connected to the second jaw. A link is pivotally connected to both the first and second handle. A detent device, or piezo electric crystal and read out are provided in the structure to give either a release or a read out response responsive to the generation of a predetermined force load on a work piece.

Abstract: An improved epicyclic power transmission is disclosed. An input shaft is journalled on a torque plate. Gears are mounted on eccentrics on the input shaft. Chain connects the gears to the torque plate to prevent rotation of the gears but permit gyration of the gears. The chain also connects the gears to an output shaft whereby the gyratory motion of the gears is translated to rotation of the output shaft on an increased torque and reduced speed.

Abstract: A hand operated crimping tool comprising a crimping head 10 and a pair of operating handles 12 for actuating said crimping head. At least one of said handles includes a force sensing arrangement including detent mechanism for maintaining handle portions 80, 88 in an unloaded position until a predetermined crimping force is applied by the crimping head whereupon the detent mechanism releases to allow slight, relative pivotal motion between the handle portions. The detent arrangement includes a tapered extension post 90 defining a recess 100 and a grip 80 pivotally connected to the post. The grip slidably mounts a spring biased slider 98 which defines a recess, confrontingly aligned with the recess in the tapered post when the grip and extension are in an unloaded position. A detent ball 94 is captured between the confronting recesses. The force exerted by the slider on the detent ball resists pivotal movement between the grip and the extension.

Abstract: A composite gear device having a large toothed wheel and a smaller toothed wheel axially offset with respect to each other. A link chain is provided having the same number of tooth engaging openings as the number of teeth on the larger toothed wheel. The chain is secured to the large toothed wheel, preferably by straining it within its elastic limit, so that the chain engages the teeth in an essentially nonflexible configuration free of any articulative movement. The smaller toothed wheel also engages the chain thus allowing the transmission of power in essentially an axial direction.
