A variable acceleration curved surface spiral gear transmission mechanism for accelerated oscillator damper damping systems is disclosed. Through the orthogonal orbit planetary gear set moving along the parallel circular arc line guide rail, the concave surface spiral gear and the convex surface spiral gear are meshed at different radii, so as to realize the continuous changing of the speed ratio and changing of the acceleration of the additional mass block. The spiral curve limit guide groove is set on the surface of concave surface spiral gear and convex surface spiral gear, and the changing rate of speed changing ratio is adjusted by designing different spiral curves, and then the acceleration changing rate of additional mass block is controlled.

A self-adaptive heavy-duty gear transmission walking device includes a guide track. A carrying seat is slidably installed on the guide track. A loading platform is arranged on the carrying seat, and matching frames are arranged at the bottom of the carrying seat and positioned opposite from each other. A first driving mechanism, a walking mechanism, a first support bracket, a stop mechanism, and a second support bracket are arranged on the carrying seat. A vertical support mechanism and a horizontal support mechanism are arranged in the matching frame. The first driving mechanism is connected to one end of the walking mechanism. The walking mechanism penetrates through the carrying seat and is magnetically connected to the guide track. The other end of the walking mechanism is connected to a first transmission shaft. The first transmission shaft penetrates through the first support bracket and is fixedly installed with a brake disc.

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.
