Weigao Cycloid Pinwheel Reducer with Frame: Integrated Bearing & Stable Transmission Solution
I. Product Overview
Weigao Cycloid Pinwheel Reducer with Frame is a heavy-duty integrated transmission device integrating optimized double-eccentric H mechanism and one-piece load-bearing frame. As a specialized upgrade of traditional cycloid pinwheel reducers, it is tailored for fixed-position heavy-load scenarios such as industrial conveyors, mixing equipment, and material lifting machinery. It overcomes the shortcomings of traditional frame-mounted reducers such as poor load-bearing stability, complicated assembly, and inconsistent installation accuracy. Compliant with GB/T 10855-2018 and ISO 1328 standards, with IP65/IP66 graded protection, it features GCr15 bearing steel gears, reinforced cast iron integrated frame, and anti-leakage lubrication system. Boasting advantages of stable frame bearing, smooth cycloid meshing, easy installation, and long service life, it operates stably at -20℃ to +100℃, serving as a core power component for fixed industrial transmission worldwide.
II. Core Advantages
1. Integrated Load-Bearing Frame, Stable Heavy-Load Operation
The reducer adopts an integrated frame design, integrating the reducer housing with a heavy-duty bearing base into one piece, eliminating the need for separate frame assembly. The frame is made of HT300 reinforced cast iron, undergoing aging treatment to eliminate internal stress, with a topology-optimized rib layout that enhances torsional rigidity by 40% compared with split-type frames. It supports axial load up to 50kN and radial load up to 25kN, effectively dispersing equipment vibration and load pressure. The frame bottom is designed with standardized mounting holes and level adjustment feet, ensuring installation levelness error ≤0.2mm/m and avoiding accuracy deviation caused by uneven force. The integrated structure reduces assembly time by 50% and ensures consistent installation accuracy, making it suitable for long-term fixed heavy-load operation.
2. Optimized Cycloid Meshing, Efficient Power Transmission
Equipped with an upgraded double-eccentric H mechanism and wear-resistant needle tooth sleeves, the reducer realizes smooth rolling meshing between cycloid gears and needle teeth. Gears are made of GCr15 bearing steel, undergoing carburizing quenching and five-axis precision grinding, with tooth surface hardness up to HRC 60-64 and roughness ≤Ra 0.04μm. The 180° offset eccentric sleeve design balances operation vibration, with multi-tooth meshing (simultaneous contact ratio ≥35%) ensuring uniform load distribution. It covers transmission ratio 6:1-7569:1 (single-stage/two-stage optional), rated torque 150Nm-25000Nm, and power 0.37kW-110kW. Single-stage transmission efficiency reaches 92%-95%, and two-stage efficiency 87%-90%, with the rolling friction structure reducing wear rate by 30% and extending service life to over 50000 hours.
3. Graded Protection Design, Complex Environment Adaptation
Targeting diverse industrial environments, the reducer adopts graded protection and anti-pollution design. Standard models adopt IP65 protection, combining double-lip skeleton oil seal, labyrinth structure and dust cover to effectively resist dust, sewage and light chemical vapor intrusion. Enhanced models upgrade to IP66 with corrosion-resistant coating and pressure-resistant housing, adapting to humid, dusty and corrosive working conditions such as chemical plants and coastal workshops. The optimized meshing structure and integrated frame reduce operating noise to ≤56dB at 1m, meeting industrial noise standards. Low-temperature resistant lubrication ensures stable operation at -20℃ to +100℃, and the frame is equipped with drainage holes to avoid water accumulation and equipment corrosion.
4. Adaptive Lubrication System, Convenient Maintenance
The lubrication system adopts scenario-adaptive configuration: small-power models use 2# lithium-based grease for maintenance-free operation within 12000 hours; medium and large-power models adopt ISO VG 220 extreme pressure gear oil with oil bath lubrication. The frame-integrated lubrication system is equipped with oil sight glass, quick注油口 and drain plug, facilitating oil level inspection and replacement. The first oil change is recommended after 200 hours of initial operation, and subsequent oil changes every 8000 hours under rated load. The modular structure allows quick disassembly of cycloid gears and bearings without disassembling the frame, reducing maintenance time by 40%. Standardized accessories ensure consistent transmission precision after overhaul.
III. Typical Application Fields
- Conveyor Systems: Belt conveyors, chain conveyors, integrated frame ensuring stable operation under long-distance load transmission
- Mixing Equipment: Chemical mixers, concrete agitators, anti-leakage design and strong load-bearing adapting to mixing impact
- Material Lifting: Small hoists, lifting platforms, stable meshing and low noise meeting workshop operation requirements
- Textile Machinery: Cloth rolling machines, dyeing equipment, corrosion-resistant protection adapting to humid working environments
- Agricultural Processing: Grain conveyors, fertilizer mixers, easy maintenance and dust-proof design adapting to outdoor work
IV. Key Technical Parameters
| Model Type | Transmission Ratio Range | Rated Torque | Lubrication Mode | Protection Grade |
| Single-Stage (Frame-Mounted) | 6:1-87:1 | 150Nm-8000Nm | Grease/Oil Bath | IP65 (Optional IP66) |

V. Installation & Maintenance
Select models based on transmission ratio, rated torque, and working environment (refer to the specification table). Use the frame's level adjustment feet to ensure installation levelness, fasten base bolts with specified torque (80-200N·m based on size) in diagonal sequence. Regularly inspect oil level, sealing performance and gear meshing wear, clean the frame surface and drainage holes monthly. Avoid overload operation exceeding 4 times rated load, and replenish or replace lubricant in accordance with the maintenance cycle. Entrust complex maintenance to professional technicians.
