Abstract
Apparatus for use in a variable ratio transmission has gear teeth (12) formed for engaging a facing gear wheel, each having a plane of symmetry (P) parallel to a width of the tooth. Links (30) rigidly associated with the gear teeth are sequentially interconnected to form hinge joints (32) between adjacent pairs of gear teeth, thereby forming a gear tooth sequence (11). The hinge joint (32) for each pair of adjacent gear teeth has an axis of rotation (34) lying on a plane (B) bisecting an angle between the planes of symmetry (B) of the adjacent gear teeth.

Apparatus for use in a variable ratio transmission, the apparatus comprising:
- (a) a plurality of gear teeth formed for engaging a facing gear wheel, each of said teeth having a plane of symmetry parallel to a width of said tooth;
- and
- (b) a plurality of links, each of said links being rigidly associated with a corresponding one of said gear teeth, said links being sequentially interconnected so as to faun hinge joints between adjacent pairs of said plurality of gear teeth, thereby forming a gear tooth sequence,
- wherein said hinge joint for each pair of adjacent gear teeth has an axis of rotation lying on a plane bisecting an angle between said planes of symmetry of said adjacent gear teeth.
