Publication number: 20080236332Abstract: A mechanical conversion system for receiving input from a toroidal engine that outputs an oscillating motion. The system has a gear set with facing bevel gears that mesh with radially mounted pinions. The bevel gears are mounted on a splined input shaft via bearings and one-way clutches. An overrunning clutch is coupled with each bevel gear. As the input shaft rotates in one direction, the overrunning clutch of one bevel gear is engaged and drives the one gear in the first direction, while the overrunning clutch of the second bevel gear is disengaged and allows the second bevel gear to overrun the input shaft. The overrunning clutch is a type known as a MECHANICAL DIODE®, which engages within 4.5 degrees of rotation, without significant slippage.Type: ApplicationFiled: March 30, 2007Publication date: October 2, 2008Inventors: Karl V. Hoose, Joshua C. Walls, Ryan Gauthier

Publication number: 20070295130Abstract: A method of defining a new pinion for use with a given face gear set. Tooth geometry of the new pinion is generated by a plane taking the given face gear set as reference and maintaining true conjugate actions among the original pinion, the face gear, the new pinion and the generating plane. This method makes it possible to eliminate adapter gears for applications requiring different shaft settings and/or ratios than those of the given gear set.Type: ApplicationFiled: June 22, 2006Publication date: December 27, 2007Inventor: Jie Tan

Patent number: 7171872Abstract: An adjustable mechanical screwdriver, having a receiving housing, gear housing and a deflection bevel gear. A small structural size is achieved because the driveshaft protrudes with a bearing shoulder at the drive bevel gear in a direction of the bearing shaft, which is inserted into and rotatably seated in a bearing bore of the bearing shaft. The gear housing having the deflection bevel gear and the power take-off shaft with the power take-off bevel gear is pivotable on the bearing shaft. The receiving housing receives the bearing shaft so that it cannot be rotated.Type: GrantFiled: March 2, 2006Date of Patent: February 6, 2007Inventor: Siegfried Keusch
