Abstract
A powertrain, such as a vehicular electric powertrain, includes a cycloidal speed reducer configured to reduce a speed of an output of a traction motor. The cycloidal speed reducer includes an input member configured to couple with the output of the traction motor. A cycloidal disc has a main body made of a first material and defining a plurality of circumferentially-arranged holes extending through the body. The cycloidal disc has a plurality of inserts each extending through one of the holes. The inserts are made of a second material. A plurality of circumferentially-arranged pins are each disposed in one of the holes and contacting one of the inserts. The inserts provide reinforcement in contact areas between the disc and the pins.
