ABSTRACT:
The present invention relates to a traction nipping drive employing cones, tapered cylinders, spheres and an uniquely designed angular power transfer wheel. The power transfer wheel is capable of matching the angles of the driver cones, spheres, or tapered cylinders to the driven cones, spheres or tapered cylinders, permitting them to engage each other in a point to point relationship. This point to point relationship remains continuous through the complete range of the drive. The same power transfer wheel, is thereafter also capable of engaging the cones, spheres or tapered cylinders in a point to point relationship for the entire speed range of the drive. An essential criteria of this invention is the use of a prior art technique as shown in U.S. Pat. No. 3,894,439. This technique employs the positive simultaneous driving of all driven and driver discs, cones and tapered cylinders, so that all surface movements are matched in the driving and driven action. This is accomplished by chains, gears, belts, shafts, etc.. This technique has the capacity of not only simultaneous traction, but also a controlled nipping by compression, of one or more of the components against each other.
