42CrMo Planetary Industrial Gear Set for 180 Polishing Machine Transmission

180 polishing machine gears are core transmission components for 180mm-diameter vertical/plain polishing machines, including sun gear, planet gear, internal ring gear, spindle spur/helical gear, timing gear, compatible with YCP180, HY-180, YH2M8180, etc. Made of 20CrMnTi/40Cr/42CrMo with carburizing/induction hardening + precision grinding, they feature high torque, impact resistance, wear resistance, low noise, high parallelism and long service life. They transmit power for polishing disc rotation, workpiece revolution/rotation, pressure adjustment, variable frequency speed control, directly determining flatness, roughness Ra≤0.08μm, polishing uniformity, yield ≥98.5%. They are the “transmission heart” for precision polishing of optical glass, sapphire, ceramics, semiconductors and metal parts.


Product Features

  • High torque & heavy duty: Module 1.5–3.0mm, thickened tooth root, withstand 50–200N·m torque, compatible with 11kW main motor.
  • Precise transmission & flatness: ISO Grade 6 accuracy, tooth surface Ra≤0.4μm, parallelism ≤0.008mm, uniform workpiece polishing.
  • Wear & impact resistance, long life: HRC 56–62 tooth surface, case depth 0.8–1.5mm, service life ≥8000 hours, adapt to slurry/dust environment.
  • Low noise & smooth operation: Helical/planetary meshing, clearance 0.08–0.12mm, noise ≤68dB, no vibration at high speed.
  • VFD compatible & stable speed: Adapt to 0–3000rpm variable frequency, smooth forward/reverse, no skipping/jamming.
  • Planetary structure & accurate ratio: Sun+planet+ring gear set, ratio 3:1–10:1, precise revolution/rotation synchronization.
  • Dust/corrosion/oil resistance: Blackening + anti-rust oil/nickel plating, adapt to water-based slurry, dust, humidity.
  • Wide interchangeability & easy maintenance: Fit mainstream 180 models, direct replacement, no redesign, common inventory.

Working Principle

  • Power input: Motor drives spindle/sun gear to transmit high-speed, low-torque power.
  • Planetary reduction & torque boost: Sun gear drives planet gears to revolve and rotate around ring gear, reduce speed 3–10 times, amplify torque, driving polishing disc at low speed and high torque.
  • Workpiece revolution + rotation: Planet gears drive workpiece carriers for revolution (with planet carrier) + rotation (meshing), uniform polishing on all surfaces.
  • Fixed-axis synchronous drive: Spindle helical gears drive upper/lower shafts/pressure mechanisms, synchronously control disc pressure and speed to ensure flatness.
  • VFD speed control & forward/reverse: Gears adapt to VFD motors for smooth speed adjustment and bi-directional operation, suitable for rough/finish/ultra-fine polishing.
  • Precise meshing & positioning: Precision grinding + pair lapping, central contact zone, uniform backlash, low vibration and high flatness.

Main Applications

  • Optical component polishing: 180mm spherical/aspherical lenses, prisms, sapphire windows.
  • Semiconductor/hard brittle materials: Silicon wafers, SiC, ceramic substrates, glass cover plates.
  • Metal mirror polishing: Stainless steel, aluminum, copper deburring and mirror finish.
  • Flat polishing machine transmission: Planetary/spindle gear sets for YCP180, HY-180, YH2M8180, etc.
  • Planet wheel/carrier drive: Workpiece revolution/rotation mechanisms for double-sided polishers, ensuring uniformity.
  • VFD speed control system: Adapt to 0–3000rpm VFD motors, rough/finish speed switching.
  • Pressure adjustment mechanism: Gears drive lifting/pressing components for precise polishing pressure control.
  • Old equipment replacement: Gear set replacement for 18B-9P, YH2M8180, etc.

Product Advantages

  • High torque & heavy duty, no thick material worries: Planetary structure + thickened tooth root, torque up to 200N·m, compatible with 11kW motor, no chipping on thick glass/ceramics.
  • Precise transmission & top flatness: ISO Grade 6 + precision grinding, flatness ≤0.008mm, Ra≤0.08μm, optical-grade polishing quality.
  • Wear resistance & long life, lower maintenance: HRC 56–62 + deep hardening, life ≥8000 hours, stable in dust/slurry environments.
  • Low noise & smooth operation, higher yield: Helical + planetary meshing, noise ≤68dB, low vibration, workpiece yield ≥98.5%.
  • VFD compatible & multi-process support: 0–3000rpm smooth speed control, one gear set for rough/finish/ultra-fine polishing.
  • Planetary synchronization & uniform polishing: Precise revolution+rotation coordination, full-surface coverage, uniform thickness.
  • Dust/corrosion resistance, harsh environment tolerance: Blackening/nickel plating, resist water-based slurry, dust, humidity, low failure rate.
  • Complete interchangeability & easy replacement: Fit mainstream 180 models, sun+planet+ring gear set replacement, no redesign needed.
