Latest Patents

One of Kitchell's latest patents focuses on shifting mechanisms for split-pulley variable transmissions. This invention provides a variety of shifter mechanisms designed to control the axial distance between half-pulleys, thereby regulating the transmission ratio. The design includes a differential that allows for differential driving and shifting by two inputs, enabling a change in the transmission ratio based on torque or rotation differences. This innovative approach allows the same motors that drive the output to also effect shifts in the transmission ratio, optimizing motor mass usage.

Another significant patent involves shaft couplings, which offer mechanisms for coupling the rotation of shafts with parallel but offset axes. These coupling mechanisms utilize pins that engage in pure rolling motion with respect to the contact surfaces of the input and output elements. This design reduces the need for bearings and enhances efficiency compared to traditional coupling methods. Such couplings can be applied in various contexts, including cycloidal drives and transmissions.
