Allen-Bradley 1336E-CWF20-AA2
1. Overview
The Allen‑Bradley 1336E‑CWF20‑AA2 is a high‑performance reducer primarily designed for AGV (Automated Guided Vehicle) applications. It is commonly integrated into AGV drive systems to convert the high‑speed rotation of a motor into low‑speed, high‑torque output, which drives the vehicle’s wheels or guide wheels.
This reducer is often paired with a planetary gear unit (such as the 1336‑B005) to create a two‑stage reduction system, achieving higher reduction ratios and greater torque output for demanding AGV tasks.
2. Key Specifications
- Rated Power: 90W – Suitable for small to medium‑power AGV drives
- Rated Speed: 3000 rpm – Typical input speed range
- Reduction Ratio: 20 – Primary reduction ratio (often combined with planetary reducers)
- Rated Output Torque: Approximately 3 Nm – Single‑stage output
- Input Shaft: 4‑key or 4‑key with 1 round key – Multiple options for motor compatibility
- Output Shaft: 4‑key with 1 round key – Versatile mounting options
- Weight: Approximately 2 kg – Compact and lightweight design
3. Product Features
- Compact Design: Cylindrical structure ideal for tight AGV chassis spaces
- High‑Efficiency Transmission: Precision gears deliver low noise and minimal heat generation
- Flexible Interfaces: Multiple keyway options (4‑key, round key, tapered key) for broad motor compatibility
- Durable Construction: High‑precision needle bearings and premium steel ensure long service life
4. Structure and Components
- Input Shaft: Connects to the motor and typically includes keyways for secure attachment
- Planetary or Cycloidal Gear Train: Core component responsible for speed reduction
- Bearing Assembly: Supports axial and radial loads for smooth operation
- Output Shaft: Connects to AGV drive wheels or guide wheels
- Housing: Aluminum or steel construction providing structural strength and protection
5. Application Areas
- AGVs (Automated Guided Vehicles): Core component in drive systems
- Automated Production Lines: Used in conveyor and material handling equipment
- Packaging Machinery: Drive units for conveyors and packaging lines
- Other Mobile Robots: Including cleaning robots and logistics robots
6. Installation and Maintenance
Installation
- Input Shaft Connection: Align keyways and secure the reducer to the motor using keys or set screws
- Output Shaft Connection: Attach to the AGV’s drive wheel or guide wheel assembly
- Mounting: Secure the reducer to the AGV chassis with evenly distributed bolts
Maintenance
- Regular Inspection: Check for abnormal bearing noise, overheating, or loose keys
- Lubrication: Sealed bearings are maintenance‑free; open‑type bearings require periodic greasing
- Cleaning: Keep the housing free of dust to prevent contamination
