Abstract
The invention concerns a drive shaft with a rigid support ring (1) with a cylindrical, internally geared support surface (3), with a radially flexible roller bushing (5) with an outwardly geared outer surface (7), with a drive device (30) connected with a drive shaft (11), through which over a plurality of spokes and planetary arms (40) one or several first circumference sections are held in engagement with the support surface (3) of the support ring (1), wherein each of the spokes or planetary arms (40), at least on one of its two ends, has a slit-like indentation and the spokes or planetary arms (40) are connected with each other through a one piece unitarily formed ring band, whereby the ring formed band is formed-on at least approximately at half length of the spokes or planetary arms (40).
Claims6
A corrugated gear, comprising:
- a rigid support ring (1) with a cylindrical, internally geared support surface (3);
- a radially flexible roller bushing (5) with an outwardly geared outer surface (7) and inner surface, and positioned within said support ring (1);
- an elliptically deformed drive core (30) driven by a drive shaft (11),
- a plurality of spokes or planetary arms (40), each of which is at least partially elastic, extending radially between said drive core (30) and said roller bushing (5),
- a one-piece unitarily formed ring band connecting said spokes or planetary arms (40) with each other at approximately half their length,
- wherein one or more first circumference sections (7a, 7b) of the outer surface (7) of the roller bushing (5) are held in engagement with said support surface (3) of the support ring (1).
