Abstract: A cycloidal reducer includes a housing, an input bushing mounted in the housing for input of a rotational force, and two speed-reduced output units, each of which includes a cycloidal disc, an output member, a cross Oldham coupling member, and a plurality of rolling elements. The cycloidal disc is mounted to the input bushing and has troughs formed in an end face thereof and each having a sidewall forming an inclined surface. The output member has troughs formed in an end face thereof. The cross Oldham coupling member has coupling sections, each having a sidewall forming an inclined surface. The coupling sections are respectively received in the troughs of the cycloidal disc and the output member. The rolling elements are arranged between the inclined surfaces of the cycloidal disc and the cross Oldham coupling member and between the sidewalls of the output member and the cross Oldham coupling member.

Abstract: A lubricatable ball screw device includes a ball screw shaft, a ball nut slidably sleeved on the ball screw shaft and having oil guide holes, a linear bearing unit mounted between the ball screw shaft and the ball nut, a bearing ring rotatably sleeved on the ball nut and having an oil supplying hole, a positioning portion disposed between the bearing ring and the ball nut, and an oil passage corresponding to the oil supplying hole. The oil supplying hole, the oil passage, an oil storage space of the positioning portion and any one of the oil guide holes cooperatively form a continuous oil path.
