Description

X Series Cycloidal Pin Wheel Decelerators: H-Mechanism & Wear-Resistant Meshing Solution

I. Product Overview

Weigao X Series Cycloidal Pin Wheel Decelerators, including X Series First Stage Cycloidal Pinwheel Reducer and X Series Two-Stage Cycloidal Pinwheel Reducer (E Type), are heavy-duty reliable transmission devices integrating double-eccentric H mechanism and high-wear pin-tooth meshing technology. Tailored for general industrial heavy-load scenarios such as mining conveyors, construction machinery, and textile equipment, this series overcomes the shortcomings of traditional reducers such as poor impact resistance, large volume, and high wear rate in harsh working conditions. Compliant with GB/T 10855-2018 and ISO 1328 standards, with IP65 universal protection, it features bearing steel cycloidal gears, reinforced cast iron housing, and grease-oil dual lubrication system. Boasting advantages of strong overload capacity, compact structure, low noise, and long service life, it operates stably at -20℃ to +100℃, serving as a core transmission component for general industrial equipment worldwide.

II. Core Advantages

1. Double-Eccentric H-Mechanism, Stable Heavy-Load Transmission

Adopting classic double-eccentric H mechanism design, the X series realizes smooth power transmission through the cooperation of eccentric sleeves, rolling bearings and cycloidal gears. Gears are crafted from GCr15 bearing steel, undergoing quenching and tempering, precision grinding, and surface nitriding treatment, with tooth surface hardness up to HRC 60-64 and roughness ≤Ra 0.04μm. The first-stage model uses a single cycloidal gear meshing with pin teeth, while the two-stage E type adds a secondary cycloidal transmission unit, achieving a maximum transmission ratio of 1:7569. Detailed parameters: first-stage transmission efficiency 90%-95%, two-stage efficiency 85%-90%, backlash controlled within ≤15arcmin (precision grade optional ≤8arcmin). The multi-tooth meshing design (simultaneous meshing rate ≥30%) distributes load evenly, enabling it to withstand 5 times rated load instantaneous impact, perfectly matching heavy-load intermittent operation demands.

2. Graded Deceleration Design, Scenario-Specific Adaptation

The series adopts graded design to match different speed ratio and load requirements. The first-stage model covers transmission ratio 6:1-87:1, power 0.37kW-75kW, and rated torque 120Nm-12000Nm, suitable for medium-speed heavy-load scenarios. The two-stage E type extends ratio to 99:1-7569:1, power 0.55kW-90kW, and rated torque 250Nm-18000Nm, for ultra-low-speed heavy-load applications. All models use integral cast iron housing with thickened wall and dense reinforcing ribs, optimized via finite element simulation to enhance torsional rigidity by 25%. The compact structure reduces volume by 30% compared with traditional cylindrical gear reducers, facilitating installation in narrow spaces, and the modular output shaft design supports both solid and hollow shaft configurations.

3. Enhanced Sealing Protection, Harsh Environment Adaptation

Enhanced sealing and wear resistance design adapts to harsh industrial environments. All models adopt IP65 protection, combining triple-lip oil seal, labyrinth structure and dust cover to effectively resist dust, sewage and chemical vapor intrusion. The pin teeth use wear-resistant alloy steel with needle tooth sleeves, reducing friction coefficient to 0.02 and extending meshing life by 2 times. The cycloidal gear structure optimizes NVH performance, operating noise ≤60dB at 1m, with stable operation and no obvious vibration. Low-temperature resistant lubrication matching enables reliable work at -20℃ to +100℃, and the overall service life reaches over 50000 hours under normal working conditions, reducing replacement frequency.

4. Dual Lubrication System, Low Maintenance Cost

The lubrication system adopts dual configuration for different working conditions: small-power first-stage models use lithium-based grease for maintenance-free operation within 10000 hours; large-power and two-stage E models adopt ISO VG 220 industrial gear oil with oil bath lubrication, equipped with oil sight glass and drain plug for convenient maintenance. The grease-oil dual design ensures lubrication stability while reducing maintenance workload by 40%. The modular structure allows quick disassembly of cycloidal gears and bearings, with standardized accessories ensuring consistent transmission precision after overhaul. The rolling friction mechanism minimizes wear, reducing maintenance costs and downtime for industrial production.

III. Typical Application Fields

Mining Industry: Ore conveyors, crusher auxiliary drives, first-stage models with strong impact resistance adapting to dusty environments
Construction Machinery: Concrete mixers, hoisting equipment, two-stage E type with large ratio meeting low-speed heavy-load requirements
Textile & Printing: Dyeing machine main drives, printing press transmission systems, low noise and stable operation ensuring production quality
Agricultural Machinery: Grain processing equipment, irrigation pumps, compact structure and reliable lubrication adapting to outdoor work
Chemical Industry: Chemical liquid conveyors, reaction kettle agitators, corrosion-resistant sealing adapting to chemical vapor environments

IV. Key Technical Parameters

Model Type	Transmission Ratio Range	Rated Torque	Lubrication Mode	Protection Grade
X Series First Stage	6:1-87:1	120Nm-12000Nm	Grease/Oil Bath	IP65
X Series Two-Stage (E)	99:1-7569:1	250Nm-18000Nm	Oil Bath	IP65

V. Installation & Maintenance

Select models based on transmission ratio, load type and working environment (refer to the specification table). Ensure coaxiality error ≤0.02mm during installation, fasten base bolts with specified torque (60-120N·m for first-stage, 100-180N·m for two-stage E type) in diagonal sequence. Grease-lubricated models require grease replenishment every 10000 hours; oil-bath models use ISO VG 220 gear oil, replace every 8000 hours under heavy load. Regularly inspect sealing performance and meshing wear, clean the ventilation cap monthly, and avoid overload operation exceeding 5 times rated torque. Entrust maintenance to professional industrial equipment technicians.

Weigao X Series Cycloidal Pin Wheel Decelerators adhere to the philosophy of "heavy-load reliability, compact efficiency, and low maintenance". Its double-eccentric H mechanism and high-wear meshing design break through traditional reducers' impact resistance and volume limitations, ensuring reliable operation in general industrial harsh scenarios. Backed by strict quality control and professional after-sales service, it provides cost-effective transmission solutions for mining, construction, and textile industries, establishing itself as a trusted global partner in industrial cycloidal transmission.
