# On preconditioning Schur complement and Schur complement preconditioning.

@inproceedings{Zhang2000OnPS, title={On preconditioning Schur complement and Schur complement preconditioning.}, author={Jun Zhang}, year={2000} }

A multi-speed drive has input and output shafts aligned on a first axis and connected to one another by a cone drive which has a plurality of conical surfaces sloped at various angles to form a "composite" cone. The composite cone is connected to the input shaft by a crank and rotates about a second axis which is oblique to, but intersects, the first axis at a point of intersection which is also a point of coincidence of the apexes of the conical surfaces. The composite cone rolls on one of a… CONTINUE READING
