原始 API 说明​

Create a cycloidal reducer disc for a one-tooth-difference pin ring.

This is a single-disc geometric standard part. Real compact reducers often stack two identical-lobe discs to balance output-pin side loads. In that assembly-level pattern, separate two concepts that are easy to confuse:

  • Place the two input eccentric cam centers 180 degrees apart, for example (+e, 0) and (-e, 0), so their orbit loads oppose each other. - Tooth-index the second cycloidal profile by half a lobe, not by a full 180 degree shape rotation. For a disc with n_lobes lobes, that geometric body phase is 180 / n_lobes degrees. A 10-lobe disc rotated by 180 degrees is exactly five full lobe pitches and is visually and mechanically equivalent to no tooth-index phase change.

If output-pin clearance holes must stay aligned to one shared output pin set, compensate the second disc's output_pin_phase by subtracting the same body phase before rotating the finished disc body.

Parameters ---------- n_lobes : int Number of cycloidal lobes. The matching fixed pin ring has n_lobes + 1 pins and gives a single-stage n_lobes:1 reduction. ring_pin_pitch_radius : float Radius of the fixed ring pin centers in mm. roller_radius : float Radius of the fixed ring pins or rollers used to offset the profile. eccentricity : float Input crank eccentricity in mm. gear_height : float, default 6.0 Disc thickness / extrusion height along Z in mm. bore_radius : float, default 0.0 Optional central bore radius. Zero leaves the disc unbored. output_pin_count : int, default 0 Optional number of circular output-pin clearance holes. output_pin_pitch_radius : float, default 0.0 Radius of the output-pin clearance hole centers in mm. output_pin_clearance_radius : float, default 0.0 Radius of each output-pin clearance hole in mm. output_pin_phase : float, default 0.0 Angular phase of the first output-pin clearance hole in degrees, in the unrotated disc's local frame. When a finished disc is rotated to create a tooth-index phase in a twin-disc stack, subtract that same rotation from output_pin_phase if the clearance holes should remain aligned to the same global output pins. sample_count_per_lobe : int, default 33 Number of analytic samples fitted into each lobe B-spline segment. spline_tolerance : float, default 0.005 Cubic B-spline fit tolerance in mm. max_control_points : int, default 20 Maximum poles allowed for each fitted lobe segment.
