Abstract

A drive system for a stair lift includes a motor, having a motor output configured to rotate about a first axis of rotation and at least one set of gears coupled to the motor output. The assembly further includes a pinion having pinion teeth and coupled to the at least one set of gears and configured to be driven by the motor so as to rotate about a second axis of rotation so as to mesh with rack teeth of a rack and move the pinion relative to the rack in a first direction. A first bearing is coupled to the pinion and has a first bearing surface that rotates with the pinion about the second axis, wherein the first bearing surface is configured to rotate along a rack bearing surface in a second longitudinal direction that is substantially parallel to the first longitudinal direction.
