Planetary Gear Unit Blueprint

Goal: Create a dark technical blueprint poster of a mechanical exploded assembly labeled {argument name="unit name" default="PGU-05 Planetary Gear Unit"}, with the subtitle “Exploded View & Component Reference,” styled like a precision engineering CAD reference sheet. Canvas: Square 1:1 format on a black/charcoal background with a faint grid, thin border lines, corner crop marks, small registration crosshairs at the top and bottom center, and a small sheet number “01” in the upper-right corner. Use white and light gray monoline drafting lines, with selective red highlights. Main subject: Center a detailed isometric exploded view of a planetary gear unit, vertically arranged from top to bottom. Show exactly 10 labeled component groups with leader lines on the right: 01 Cap screw (x6), 02 Top cover, 03 Ring gear internal, 04 Planet gear (x3), 05 Sun gear, 06 Planet carrier, 07 Thrust washer, 08 Output shaft, 09 Bearing (x2), 10 Housing. Render the exploded parts as transparent wireframe/technical linework with hidden construction lines and dotted alignment axes. Make the sun gear the only emphasized component in red, positioned in the middle of the assembly, with a red leader line and red label. Left information panel: At the upper left, place the title “PGU-05 PLANETARY GEAR UNIT” and subtitle “EXPLODED VIEW & COMPONENT REFERENCE.” Below it, include a specifications block with exactly 5 rows: Gear ratio 27.31:1, Max input RPM 6000, Max output torque 320 N-m, Efficiency 94%, Weight 3.7 kg. Under that, add a function overview paragraph explaining that a planetary gear set uses multiple planet gears rotating around a central sun gear while meshing with an internal ring gear, distributing load and increasing torque capacity in a compact drive train. Inset diagrams: Add exactly 2 inset boxes on the lower-left side. The upper inset is labeled “SECTION A-A” and shows a white line cross-section of the assembled gear unit. The lower inset is labeled “05 SUN GEAR [DETAIL]” and uses red linework to show the isolated sun gear with dimension arrows and annotations such as Ø18.00, Ø32.00, and Ø12.00 (H7). Right reference panel: Use compact monospaced technical text for the component list and notes. Include material and tooth-count callouts such as ring gear Z=72 module 1.25, planet gear Z=24 module 1.25, and sun gear Z=18 module 1.25. Add a notes block with exactly 5 numbered notes: all gears 20° pressure angle, gear material 20CrMnTi, heat treatment carburized, all dimensions in millimeters, tolerances ISO 2768-mK. Add a bottom scale bar labeled 1:1 with ticks from 0 to 100 mm. Visual style: High-detail CAD drafting aesthetic, thin precise strokes, clean monospaced typography, subtle glow on white linework, red accent only for the sun gear detail and corresponding callouts, no photographic shading, no color except white/gray and red. Keep all text legible and aligned like a professional mechanical drawing.
