Tepper and Lowen have shown that complete force balancing of planar linkage
is possible using simple counterweights provided that from every point on
the linkage there exists a contour to the ground by way of revolute joints
only.
This paper shows that if a linkage can be fully force balanced using the cr
iterion of Tepper and Lowen, then it can be fully force and moment balanced
using geared counter-inertias. Complete mathematical proof of this theory
is given. (C) 1998 Elsevier Science Ltd. All rights reserved.
