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.
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.
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.
Complete interchangeability & easy replacement: Fit mainstream 180 models, sun+planet+ring gear set replacement, no redesign needed.
Why Choose us?
7-axis CNC Grinding:We adopt high-precision 7-axis CNC grinding machines, holding tolerances as tight as ±5μm, ensuring gears run quietly, smoothly and with outstanding durability.
Strong technical expertise: Our core R&D team includes doctoral and master’s professionals specializing in spiral bevel gear technology, providing strong technical support for complex projects.
Rigorous testing & high precision:All gears undergo 100% inspection with Gleason metrology systems. We can achieve DIN 6 grade accuracy with strict control over tooth profile and direction errors, keeping our quality at the industry-leading level.
High transmission efficiency: Our gear designs support a single-stage reduction ratio of up to 300:1, with actual transmission efficiency reaching over 95%, greatly improving energy utilization.
Excellent durability & cost efficiency: Our gears deliver 40% lower lifecycle cost and a failure rate below 0.5%, ensuring stable long-term operation and reduced maintenance costs.
Fast response & short lead time: Supported by our digitalized production process, we are able to shorten the delivery cycle to only 20 working days, helping you accelerate project development and launch.
Professional custom design capability:We provide fully customized gear solutions for applications requiring high-reduction, high-speed, heavy-load, low-noise, and special small-tooth profiles, based on your actual working conditions.
