    Three-planet 4:1 gearbox open assembly

    Three-planet 4:1 gearbox open assembly, modeled from published dimensions. Overall 108 x 108 x 31.5 mm. Key dimensions: module 1.5 mm; pressure angle deg 20; sun teeth 18; planet teeth 18; ring teeth 54; planet count 3; planet center radius 27 mm; ratio ring fixed 4; gear face width 12 mm; sun bore 8 mm; planet bore 6 mm; case mount PCD 100 mm; case mount holes 5.2 mm. Original three-planet arrangement: 18-tooth sun, three 18-tooth planets, internal 54-tooth ring. Ring fixed gives 4:1 sun-to-carrier reduction. Three equally spaced planets satisfy (18+54)/3 = 24 for assembly phasing. Spline-fitted 20-degree involutes and selected backlash. Case, carrier, pins, washers and gears are separate solids; the lower housing clears the rotating carrier. Bearing races, seals, fasteners and lubrication are omitted. No load rating or manufacturing gear class is claimed. Exact solid STEP geometry in millimeters, opens in any CAD system. Export to STL, OBJ, GLB and other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.

Rail race relief, carriage internal cavity and end-cover shapes are reconstructed. Recirculating balls and grease nipple are omitted. M3 taps are nominal cylindrical envelopes; no running clearance, preload or load performance is simulated. Exact solid STEP geometry in millimeters, opens in any CAD system. Export to STL, OBJ, GLB and other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.

    UCP205 pillow-block bearing

    UCP205 pillow-block bearing, modeled from published dimensions. Overall 140 x 38.8 x 75.4 mm. Key dimensions: bore 25 mm; shaft axis height 36.5 mm; length 140 mm; base width 38 mm; bolt pitch 105 mm; foot height 16 mm; housing height 70 mm; insert outer diameter 52 mm; insert width 34.1 mm; insert short offset 14.3 mm; grease fitting 1/4-28 UNF nominal, thread omitted. Shaft height, bore, mounting slots, base envelope and insert datums follow the Koyo tables. Housing H2 excludes the grease fitting; its reconstructed fitting adds 5.35 mm. Cast contour, ribs, relief, seal/race details and screw heads are reconstructed. Spherical outer ring is shown upright in a simplified cylindrical seat; self-alignment, rolling elements, preload and load rating are not simulated. M6 set screws have cylindrical thread envelopes. Exact solid STEP geometry in millimeters, opens in any CAD system. Export to STL, OBJ, GLB and other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.
