ZPLE Series Planetary Reducer: Bevel Gear Planetary & Quick-Disconnect Modular Solution
I. Product Overview
Weigao ZPLE Series Planetary Reducers, covering models ZPLE60, ZPLE80, ZPLE90, ZPLE120, and ZPLE160, are flexible precision transmission devices integrating spiral bevel planetary gear trains and quick-disconnect modular technology. Tailored for medium-high end servo scenarios such as industrial robot joints, semiconductor equipment, and new energy test platforms, this series overcomes the shortcomings of traditional reducers such as poor servo compatibility, cumbersome disassembly, and limited installation flexibility in precision transmission fields. Compliant with ISO 6336 gear standards and AGMA 6123 certification, with IP65/IP66 adaptive protection, it features spiral bevel precision gear sets, high-strength cast aluminum (small models) and nodular cast iron (large models) housing, and servo-specific lubrication system. Boasting advantages of spiral bevel stable transmission, quick-disconnect maintenance, wide servo adaptation, and compact structure, it operates stably at -25℃ to +100℃, serving as a core component for flexible precision industrial equipment worldwide.
II. Core Advantages
1. Spiral Bevel Planetary Gear Train, Stable & Low Noise
Adopting integrated spiral bevel planetary gear structure, the ZPLE series combines the advantages of spiral bevel gear low-noise meshing and planetary gear load sharing, achieving superior motion stability. Gears are crafted from 20CrNiMo6 alloy steel, undergoing deep carburizing, precision grinding, and spiral tooth profile modification to ISO 5-level accuracy, with tooth surface hardness up to HRC 62-64 and roughness ≤Ra 0.03μm. The spiral bevel design realizes continuous meshing with high contact ratio, reducing operating noise by 15% compared with hypoid gears, and enhancing impact resistance by 20%. Detailed precision parameters: tooth profile tolerance (f) ≤0.008mm, cumulative pitch error (F) ≤0.020mm, backlash controlled within ≤2arcmin (small models) and ≤3arcmin (large models, optional ≤1.5arcmin). Single-stage transmission efficiency hits 96%-98.5%, torque density reaches 16Nm/cm³, speed ratio 3:1-100:1 (multi-stage extendable to 3000:1), perfectly matching high-precision servo motion demands.
2. Quick-Disconnect Modular Design, Efficient Maintenance
The series features a quick-disconnect modular structure, realizing separate disassembly of gear box, motor flange, and output shaft without integral removal, shortening maintenance time by 70% compared with traditional structures. ZPLE60-ZPLE160 form a graded product matrix: ZPLE60-ZPLE90 (cast aluminum housing) cover 0.5kW-45kW power and 600Nm-5000Nm torque for medium precision servo load; ZPLE120-ZPLE160 (nodular cast iron housing) cover 55kW-132kW power and 6000Nm-26000Nm torque for heavy-duty servo scenarios. Housing structure optimized via finite element simulation enhances integral rigidity, resisting 1.8 times rated load impact, and the modular design supports customized combination of flanges and shafts, adapting to diverse installation layouts without additional adapters.
3. Enhanced Sealing Protection, Harsh Environment Adaptation
Adaptive protection design matches different servo application environments. ZPLE60-ZPLE90 adopt IP65 protection (double-lip fluorine rubber oil seal + labyrinth structure) for precision workshops, with hard anodized anti-corrosion treatment (salt spray resistance ≥1200 hours). ZPLE120-ZPLE160 configure IP66 protection on demand, adding stainless steel dust cover and pressure-resistant sealing ring to resist coolant and heavy dust intrusion, with electrophoretic anti-corrosion treatment (C3 grade). The spiral bevel gear structure optimizes NVH performance, operating noise ≤52dB (small models) and ≤56dB (large models) at 1m. Low-temperature resistant lubrication matching enables stable operation at -25℃ to +100℃, service life extended to over 45000 hours under normal continuous servo operation.
4. Servo-Specific Lubrication, Long-Term Precision Retention
The lubrication system adopts fully synthetic servo-specific gear oil (ISO VG 150), featuring excellent anti-wear, anti-oxidation, and low-temperature fluidity, matching frequent servo start-stop and high-response operation. Small models use sealed oil bath lubrication for maintenance-free operation within 20000 hours; large models adopt forced circulation lubrication with online oil quality sensor for real-time monitoring. The modular lubrication module allows quick oil change without disassembling servo connections, with oil change cycle extended to 15000 hours for continuous heavy-load servo operation. Standardized precision accessories ensure consistent meshing precision and backlash control after overhaul, maintaining servo system stability.

V. Installation & Maintenance
Select models based on rated torque, servo connection mode, and working environment (refer to the specification table). Ensure coaxiality error ≤0.015mm during installation, fasten quick-disconnect flange bolts with specified torque (35-65N·m for ZPLE60-ZPLE90, 80-130N·m for ZPLE120-ZPLE160) in diagonal sequence. Use ISO VG 150 servo-specific gear oil, replace every 15000-20000 hours based on operation frequency. Regularly inspect sealing performance and modular connection tightness, calibrate backlash every 12 months. Avoid overload operation exceeding 1.8 times rated torque, and entrust maintenance to professional servo equipment technicians.
