Abstract: An orbital tensile drive is herein disclosed, along with systems and methods associated therewith. The orbital tensile drive uses a tensile element that is conveyed around a static, fixed shaft and a rotating output shaft. This is facilitated via multiple orbiting idler pulleys that are mounted to an orbiter body. The static and rotating shafts, as well as the orbiting assembly, share a common axis. Input rotation to the orbiter body is transformed into lower-speed, higher-torque rotation at the rotating output shaft. The present invention has many potential applications including, but not limited to, robotics.

Abstract: Described is a generator for an engine-driven power system. The generator having a generator shaft, a sleeve coupler, a first pulley, and a second pulley. The generator shaft, which is shaped at an end to define a first tapered surface, rotates a rotor relative to a stator. The sleeve coupler is shaped to define a bore with a second tapered surface. The bore receives the end of the generator shaft. The first pulley has a center hole to receive the sleeve coupler. The second pulley shares an axis of rotation with the first pulley and transfers a rotational force to the generator shaft and to the sleeve coupler.

Abstract: A Pulley device for a tensioning or winding roller for a transmission element including a pulley, and a rolling bearing provided with a rotating outer ring, the pulley being mounted on an outer surface of the outer ring, a fixed inner ring, the rings being coaxial and forming a radial space between them, and at least one row of rolling elements arranged in the radial space. The pulley device further includes at least one annular protection flange with a radial body. The flange is fixed to the rotating outer ring by crimping an axially protruding portion of the pulley towards an outer edge of the flange.

Abstract: A freely running sheave of a belt drive is supported on an angularly adjustable spindle for adjusting the angular orientation of the freely running sheave. The angular orientation of a spindle is changeable by a first wedge-shaped element and a second wedge-shaped element which each include a surface enclosing an acute angle relative to an orthogonal with respect to a longitudinal axis of the spindle. The wedge-shaped elements are flattened on opposite outer peripheral surfaces such that an open-end wrench can in each case be engaged therewith.

Abstract: A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element configured to receive a screw, a rotating outer element that is mounted to rotate coaxially about the fixed inner element and is intended to cooperate with the transmission element, and an annular protective flange bearing against a lateral surface of the fixed inner element. The fixed inner element provides a sleeve axially protruding from the lateral surface. The flange provides an inner axial portion mounted securely on an outer surface of the sleeve.

Abstract: A pulley stopper including: a clamp portion that includes a bar-shaped upper clamp and a bar-shaped lower clamp; and a pair of fasteners that are disposed at opposite ends of the clamp portion to couple the upper clamp and the lower clamp. The pair of fasteners and the clamp portion are coupled such that the upper clamp and the lower clamp are fixed side by side through the coupling of the fastener and the movement of a belt disposed between the upper clamp and the lower clamp is stopped.

Abstract: In an aspect, a power transfer device, such as a decoupler, is provided for transferring torque between a shaft and a belt. The device includes: a hub configured to couple to the shaft, a pulley rotatably coupled to the hub that includes a power transmitting surface configured to engage the belt, an isolation spring to transfer a rotational load from one of the pulley and the hub to the other of the pulley and the hub, optionally a one-way clutch to permit overrunning of one of the pulley and the hub relative to the other of the pulley and the hub in a first direction, and a damping member positioned to be driven into frictional engagement with a friction surface by a force from the isolation spring acting on the damping member that varies based on the rotational load transferred by the isolation spring.
