Planetary Gear Unit Blueprint

Full prompt

Goal: Create a dark technical blueprint poster showing a mechanical exploded assembly diagram, labeled PGU-05 planetary gear unit, with the subtitle “Exploded View and Component Reference,” in a style modeled after precision engineering CAD reference drawings.

Canvas: 1:1 square format, black/charcoal background, with a light grid, thin border lines, corner crop marks, small alignment crosshairs at the top and bottom center, and a small drawing number “01” in the upper right corner. Use white and light gray single-line drawing strokes, supplemented by localized red highlights.

Main subject: Place a detailed isometric exploded view of a planetary gear unit in the center, arranged vertically from top to bottom. On the right side, use leader lines to label 10 component groups: 01 socket head cap screws (x6), 02 top cover, 03 internal ring gear, 04 planet gears (x3), 05 sun gear, 06 planet carrier, 07 thrust washer, 08 output shaft, 09 bearings (x2), 10 housing. Render the exploded parts as transparent wireframe/technical lines, including hidden construction lines and dashed alignment axes. Present the sun gear as the only emphasized component in red, positioned in the middle of the assembly, with red leader lines and a red label.

Left information panel: In the upper left, place the title “PGU-05 planetary gear unit” and the subtitle “Exploded View and Component Reference.” Below, include a specifications block with 5 rows: gear ratio 27.31:1,
Maximum input speed 6000 RPM, maximum output torque 320 N-m, efficiency 94%, weight 3.7 kg. Add a functional overview below, explaining how the planetary gear set distributes load and increases torque capacity in a compact transmission system by having multiple planet gears rotate around the central sun gear and mesh with the internal ring gear.

Illustrations: add 2 inset boxes in the lower left. 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 lines to show the standalone sun gear, with dimension arrows and annotations such as Ø18.00, Ø32.00, and Ø12.00 (H7).

Right-side reference panel: component list and notes use a compact monospaced technical font. Include material and tooth-count annotations, such as internal ring gear Z=72 module 1.25, planet gears Z=24 module 1.25, sun gear Z=18 module 1.25. Add a note block containing 5 numbered notes: all gears pressure angle 20°, gear material 20CrMnTi, carburizing heat treatment, all dimensions in millimeters, tolerances conform to ISO 2768-mK. Add a scale marked 1:1 at the bottom, with graduations from 0 to 100 mm.

Visual style: high-detail CAD drawing aesthetic, thin and precise lines, clean layout with monospaced fonts, white lines with a faint glow,
Only the sun gear details and related annotations use red accents; no photographic shadows; no colors other than white/gray and red. Ensure all text is clear and legible, and aligned like a professional mechanical drawing.
