Abstract: An apparatus for a quick release cutting device blade assembly is provided. The apparatus includes a blade carrier assembly. The blade carrier assembly includes an adaptor and a backing plate configured to fit over the central post and including a second flat surface. The adaptor includes a flat end plate including a first flat surface, a central post, and a female threaded portion configured to be engaged to a male threaded portion of an output shaft of a cutting device. The blade carrier assembly is configured to affix a cutting device blade between the first flat surface and the second flat surface. The female threaded portion includes a thread pattern configured for resisting a tool-lock condition when a force transmitted through teeth of the thread pattern is maintained below a maximum operational force.

Abstract: A continuously variable transmission for use with motor vehicles includes an ECU, an automated gear unit, a variator, an input gear set, an input fixed ratio element and an output fixed ratio element. The automated gear unit has multiple gear ratios and engages one of the gear ratios responsive to commands from the ECU. The variator varies a ratio of torque between its input and output shafts responsive to commands from the ECU. The variator output shaft connected to the gear unit input shaft. The input gear set is connected to the variator input shaft. The input fixed ratio element reduces torque from the input gear set to the variator, and is disposed between the input gear set and the variator input shaft. The output fixed ratio element increases the torque from the variator, and is disposed between the variator output shaft and the gear unit input shaft.
