Overview

This document provides detailed technical specifications for various planetary gearheads, focusing on pinion types, gear characteristics, and mechanical performance parameters. The data is presented primarily in tabular form with dimensions in millimeters and inches, and includes torque, speed, efficiency, load capacities, backlash, and physical dimensions.

1. Pinion Types and Dimensions

The document lists multiple pinion types identified by codes such as ZCP, ZJP, ZMP, ZAP, ZFP, SJP, SMP, SAP, and SFP, each associated with specific gearhead sizes (e.g., φ7.0, φ13.0, φ16.0, φ20.0, φ32.0, φ42.0). Key dimensional parameters include pinion diameter, length (L), mounting hole specifications (e.g., 4-M1.6×0.35 depth 2.5), pitch circle diameter (P.C.D.), and tolerances.

2. Gear Specifications

For each gearhead size and pinion type, the document provides comprehensive gear specifications including:

• Reduction Ratio: Ranges from 1/4.00 up to 1/1296.00 depending on model.
• Permissible Output Torque: Given in Newton-meters (Nm), kgf·cm, and oz-in, varying by reduction ratio and gearhead size.
• Permissible Output Power: Specified in Watts (W), indicating maximum power transmission capability.
• Maximum Input Speed: Maximum allowable input rotational speed in revolutions per minute (rpm), typically 7000 to 14000 rpm depending on gearhead size.
• Efficiency: Percentage efficiency values ranging from approximately 41% to 90%, decreasing with higher reduction ratios.
• Permissible Radial and Thrust Loads: Radial and thrust load capacities in Newtons (N) and kgf, indicating mechanical load limits.
• Backlash: Angular backlash in degrees, generally around 1.5°, indicating gear play tolerance.
• Physical Length (L): Length of the gearhead in millimeters and inches, increasing with size and reduction ratio.
• Weight: Weight in grams, increasing with gearhead size and complexity.

3. Mechanical and Dimensional Details

The document includes precise mechanical dimensions for mounting and assembly, such as screw sizes, hole depths, and pitch circle diameters, critical for integration into mechanical systems. Tolerances are specified to ensure manufacturing precision.

4. Performance Trends and Recommendations

• Higher reduction ratios correspond to lower permissible output torque and efficiency but allow for greater torque multiplication.
• Maximum input speeds are limited by gearhead size and design, with smaller gearheads supporting higher speeds.
• Backlash is consistently maintained at approximately 1.5 degrees across models, balancing precision and mechanical tolerance.
• Radial and thrust load capacities increase with gearhead size, indicating suitability for heavier mechanical loads.
• Weight and physical length increase with gearhead size and reduction ratio, impacting design considerations for space and mass.

5. Units and Measurement Standards

All dimensions are provided in millimeters with inch equivalents in parentheses. Torque is given in Nm, kgf·cm, and oz-in. Load capacities are in Newtons and kgf. Speed is in rpm, and power in Watts.

Summary

This technical document serves as a comprehensive reference for selecting planetary gearheads based on pinion type, reduction ratio, mechanical load capacity, efficiency, and physical dimensions. It is essential for engineers designing systems requiring precise gear reduction with defined torque and speed limits, ensuring compatibility and performance reliability.
