A dark technical blueprint poster of a mechanical exploded assembly labeled "[PGU-05 Planetary Gear Unit]", with the subtitle "Exploded View & Component Reference", styled as a precision engineering CAD reference sheet. Composition & Layout: Square 1:1 format on a charcoal-black background with a faint coordinate grid, fine border lines, corner crop marks, registration crosshairs at top and bottom center, and sheet number "01" in the upper-right corner. Center Subject: Isometric exploded view of the planetary gear unit vertically aligned from top to bottom. Rendered in transparent wireframe CAD linework with hidden construction lines and dotted center alignment axes. Exactly 10 labeled component callouts 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. The central sun gear is the only part highlighted in bold technical red linework with matching red leader line and red text label. Left Panel: Upper title block reading "[PGU-05 PLANETARY GEAR UNIT]" and subtitle "EXPLODED VIEW & COMPONENT REFERENCE". Below, a 5-row technical specifications block: "Gear ratio 27.31:1", "Max input RPM 6000", "Max output torque 320 N·m", "Efficiency 94%", "Weight 3.7 kg". Below that, a brief functional description paragraph describing epicyclic gear distribution. Lower-Left Insets: Two bordered inset boxes. Top inset labeled "SECTION A-A" showing a white cross-section linework diagram of the assembled unit. Bottom inset labeled "05 SUN GEAR [DETAIL]" showing an isolated sun gear in red linework with dimension arrows and annotations "Ø18.00", "Ø32.00", and "Ø12.00 (H7)". Right Panel: Compact monospaced technical callouts for gear data (ring gear Z=72 module 1.25, planet gear Z=24 module 1.25, sun gear Z=18 module 1.25). A 5-point notes section specifying 20° pressure angle, 20CrMnTi carburized steel, metric dimensions, and ISO 2768-mK tolerances. Bottom 1:1 metric scale bar marked 0 to 100 mm. Style: Precise vector monoline aesthetic, white and neutral light gray technical lines on dark background, selective red accent only for the sun gear, crisp legible typography, no photographic textures or gradients.
