ABSTRACT:
The present invention provides a drive apparatus comprising a track rail having a track formed along its axial direction, and a slider guided by the track. The slider has a rolling element circulating path, and a torque generating device, having an output shaft, is mounted on the slider. The apparatus also includes a plurality of drive rollers and at least one substantially spherical rolling element disposed in the rolling element circulating path. The torque generating device applies a torque to the drive rollers to cause the drive rollers to roll while engaging with the track rail to move the slider along the track, and the rolling elements contact the track rail and move along in the rolling element circulating path when the slider moves along the track. The apparatus further includes an oil film forming device which forms an oil film between the track rail and the drive rollers.
