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 spacer includes a first surface and a second surface. The first surface and the second surface respectively have two opposite first roller accommodating grooves and two opposite second roller accommodating grooves. The first and second roller accommodating grooves of the first surface correspond to the second and first roller accommodating grooves of the second surface. The spacer defines a reference plane, which is perpendicular to a horizontal direction and passes through a center point of the maximum thickness of the spacer. The horizontal distance from the reference plane to the center of each first roller accommodating groove is different from the horizontal distance from the reference plane to the center of each second roller accommodating groove. By flipping the spacer of the present invention, the spacing of two adjacent rollers can be adjusted. In addition, the present invention further provides a cycloidal reducer with the aforementioned spacer.
