Speed-reduction or speed-increasing drive

摘要

The drive has an input shaft (10) and a coaxial output shaft (20), each of which carries a chain wheel (16 and 18 respectively). In the simplest exemplary embodiment, the chain wheel (16) is rotatably mounted on an eccentric end (12) of the input shaft (10) and lies axially opposite the output chain wheel (18). As a transmission element, use is made of a double chain (26), the two halves of which mesh with the respectively associated chain wheel and the number of teeth of which is greater than the number of teeth of the respective chain wheel. <IMAGE>
