Claims45
A speed change device comprising:
- an inner race having an outer surface;
- an outer race having an inner surface;
- a set of orbital rollers including inner rollers in rolling contact with the outer surface of the inner race and outer rollers in rolling contact with the inner surface of the outer race, wherein the outer rollers are longer than the inner rollers and the outer rollers are connected to be driven by an input ring coaxial with the inner race and the outer race;
- each inner roller being in rolling contact with two outer rollers;
- and
- either A or B or both:
- A:
- each inner roller is formed of two or more axially aligned roller sections, each section having a respective cylindrical torque transmitting surface;
- B:
- each outer roller is formed of two or more axially aligned roller sections, each section having a respective cylindrical torque transmitting surface.
