Overview

The document provides detailed technical specifications and features of the CP series low backlash planetary gearheads, designed as economical entry-level models suitable for simple applications. These gearheads are noted for their quality, availability, and reliability, with versions optimized for cyclic or continuous operation.

Product Features

• Low backlash planetary gearhead with output shaft
• Economical entry-level model
• Suitable for cyclic operation (duty cycle ≤ 60%) and continuous operation (duty cycle ≥ 60%)
• High power density and positioning accuracy
• Capability for high input speeds
• High torsional rigidity
• Space-saving and lightweight design
• Lubricated for life with food-grade lubrication available on request
• Protection class IP64
• Aluminum paint finish
• Motor and gearhead rotate in the same direction

Versions and Accessories

The CP series includes multiple sizes (CP 040, CP 060, CP 080, CP 115) with 1-stage and 2-stage configurations. Accessories include coupling and B5 flange options. Motor mounting follows the operating manual, with CAD data available online.

Technical Specifications

Key parameters are provided for each size and stage, including:

• Gear Ratios: Range from 4 to 100 depending on model and stage
• Maximum Input Speed: Up to 8000 rpm for smaller sizes, 6000 rpm for larger sizes
• Nominal Output Torque: Varies by size and ratio, e.g., CP 040 up to ~0.58 Nm, CP 115 up to ~6.1 Nm
• Maximum Acceleration Torque: Specified for up to 1000 cycles per hour
• Emergency Stop Torque: Permitted 1000 times during gearhead service life
• Torsional Backlash: Typically ≤ 20 arcmin standard, with reduced backlash options
• Torsional Rigidity: Provided in Nm/arcmin, indicating resistance to twisting
• Maximum Axial and Radial Forces: Specified in Newtons and pounds-force, relating to output shaft center at 100 rpm
• Efficiency: Approximately 93% to 97% at full load
• Service Life: Exceeds 20,000 hours under specified conditions
• Operating Noise: Measured at no load and 3000 rpm, typically around 45-50 dB(A)
• Weight: Varies by size, from approximately 0.31 kg (CP 040) to 6.9 kg (CP 115)
• Ambient Temperature Range: -15°C to +40°C (5°F to 104°F)

Design and Installation Notes

• Non-tolerated dimensions ±1 mm
• Motor shaft fit must be checked; minimum and maximum permissible motor shaft lengths are specified
• Smaller motor shaft diameters can be compensated with bushings
• Motor mounting must follow the operating manual
• CAD data available for design integration

Summary Tables and Data Interpretation

The document includes comprehensive tables listing detailed numerical data for each CP model and gear ratio, covering torque values, speeds, backlash, rigidity, forces, efficiency, service life, weight, noise, and temperature limits. These tables enable precise selection of gearheads based on application requirements, balancing torque capacity, speed, size, and durability.

Critical Recommendations and Limitations

• For higher ambient temperatures, input speed must be reduced to maintain performance and longevity
• Emergency stop torque is limited to 1000 cycles during the gearhead's service life
• Lubrication is lifetime sealed; no maintenance lubrication required
• Protection class IP64 ensures dust and splash water resistance but not full immersion

Conclusion

The CP series planetary gearheads offer a reliable, cost-effective solution for applications requiring low backlash, high precision, and durability in compact form factors. The detailed technical data supports informed selection and integration into motor-driven systems, with clear guidelines on operational limits and installation.
