Discussion of a variant of eccentric drives utilizing rolling elements

Abstract In this paper a variant of eccentric drives will be described, which uses rolling elements instead an gear. These are constrained by concentric carrier allowing for radial movement and moved crank. They mesh with gear geometry that translates their into tangential constrains position. Multiple offset eccentricities may used the same to reduce occurring forces. Such drive prove easier manufacture than currently drives, but characteristics not yet fully researched. The components working principle such consistent names established in paper. Using these resulting mathematically described. forces on singular element derived. An overview comparison related mechanisms given aid classification drive. Different variations discussed, including choice elements, whether use external or internal gear, direction-reversing non-direction-reversing is advantageous.
