A tool changing system with rigidity improved belt moving mechanism includes a pedestal, a sliding base, a driving unit, a positioning belt, and a transmission belt. The sliding base is disposed on the pedestal, and reciprocatively moves along a linear direction. The driving unit is disposed on the sliding base. The positioning belt and the transmission belt are disposed on the pedestal and include a gear rack, respectively. A detouring section of the transmission belt is separated from the positioning belt, and transmissibly meshed with the driving wheel of the driving unit. When the driving wheel rotates, the detouring section is driven to continuously shift on the transmission belt, and the sliding base is simultaneously driven to slide on the pedestal along the linear direction. Thus, a combination of the positioning belt and the transmission belt achieves an improved rigidity.

The present invention concerns an angular transmission device comprising: An input shaft and an output shaft, An assembly arranged for coupling the input shaft with the output shaft so that the output shaft can be rotationally driven by the input shaft, the assembly comprising a rotary actuator and a linear mobile, the rotary actuator being coupled with the input shaft and moves the mobile in a translation motion relative to the actuator, the mobile being coupled with the output shaft so that the rotation of the input shaft drives the rotation of the output shaft; the assembly further comprises a flexible blade fixed to said mobile and looped around the output shaft, so that when the actuator moves the mobile, the flexible blade drives the rotation of the output shaft. The invention also comprises a method using said device.

The invention provides a cable drive device (10) including a linear drive member (12), and a cable drum (14) attached to a support bracket (30, 32) adapted to be affixed to a surface. The cable drum (14) has an axle (26) supported by the support bracket (30, 32) to allow rotation of the cable drum (14). The cable drum (14) has a cable (42) affixed at either end of said linear drive member (12) and tautly wrapped around the cable drum (14). The cable drum (14) is located between the ends of the linear drive member (12) to, in use, allow the linear drive member (12) to be guided through the bracket (30, 32) to move the linear drive member (12) longitudinally when the axle (26) is rotated.

Provided is a rear axle movement device for a truck with a lowerable bed, comprising: a front axle, a driver's cab, a rear axle, a cargo container, a sub-frame, a first lifting device, a second lifting device, a first guiding device, a second guiding device, and an electric motor. According to the present invention, the rear axle movement device utilizes a chain and a sprocket.

Disclosed herein are methods, systems, and components for the design of a flat belt based block and tackle design that is theoretically free of fleet angles. A mapping technique forms a set of planar positions for the centerlines of the free spans that provides a plurality of sheave geometries, which reside on a common axis and spans that are free of fleet angles at the sheave engagement interfaces. This permits the use of high-performing flat belts in high-reduction (e.g., 6:1 or greater) block and tackle topologies, with the principal benefits of an extended service life, high power transmission efficiency, more effective traction power transfer, and a compact machine design.

The present invention relates to a flat belt (10) that is an open end belt to be fixed to a coupler (31, 41), in which the flat belt (10) contains, formed on both end portions (11, 12) of at least one surface of the flat belt (10), a plurality of projected portions (13) engageable with a plurality of recessed portions (33, 43) formed on the coupler (31, 41).

An information handling system may include a chassis, a bay within the chassis for receiving a modular information handling resource, and a pulley assembly within the chassis and adjacent to the bay, the pulley assembly comprising a handle mechanically rotatable between a closed position and an open position, a pulley subsystem comprising a pulley cable mechanically coupled to the handle, and a carrier mechanically coupled to the pulley subsystem and configured such that the modular information handling resource rests on the carrier when the modular information handling resource is installed in the information handling system. The pulley assembly may be arranged such that force applied to the handle when the handle is in the open position provides a mechanical advantage via the pulley subsystem to mechanically translate the carrier in accordance with the force and the mechanical advantage to cause at least partial removal of the modular information handling resource from the bay in response to the force.

An arrangement for controlling and measuring flow. The arrangement includes a fluid control barrier and a flow-measuring apparatus upstream of the fluid control barrier. The fluid control barrier includes a pair of plates for opening and closing a pipe, and the plates are movable towards a center line of the pipe to open the pipe and produce a symmetrical flow profile for the flow-measuring apparatus.

The disclosure provides apparatuses, systems, and methods for belt driven linear actuator systems.
