This frame is suitable for connecting cycloidal pinwheel reducers, equipped with rigid couplings. The upper coupling is equipped with JA type straight holes, and the lower coupling is equipped with A-type straight holes or B-type tapered holes, with a taper of 1:20. This rack is unsupported and suitable for use when the axial force transmitted from the reactor is not significant.
