Standard Series 3R20 External Gear Technical Specifications

This document provides detailed technical specifications for the Standard Series 3R20 external gears. The data is organized in a tabular format listing key dimensional and mechanical parameters for five different gear models.

1. Gear Identification and Weight

• Each gear is identified by a unique code (e.g., E.1462.3R20.01.01).
• Weight ranges from 540 kg to 910 kg across the models.

2. Dimensional Parameters

The table includes multiple diameter measurements for both the outer ring and inner ring components of the gears:

• Outer Ring Diameters: Outer diameter, pitch diameter, inner diameter, bolt circle diameter, external hole diameter, and hole count.
• Inner Ring Diameters: Outer diameter, pitch diameter, inner diameter, bolt circle diameter, internal hole diameter, hole count, and thread depth.
• Dimensions are given in millimeters (mm).

3. Mechanical and Structural Parameters

• Module (gear tooth size) is consistently 12 to 16 mm depending on the model.
• Number of teeth varies from 106 to 137 across the series.
• Thickness (height) of outer and inner rings is specified, contributing to overall gear height.
• Ball track diameter and other bearing-related dimensions are included to ensure compatibility with bearing assemblies.

4. Summary of Key Dimensions for Each Model

5. Recommendations and Usage Notes

The document implies these gears are designed for heavy-duty applications requiring precise dimensional compatibility with bearing assemblies. The detailed hole counts and diameters suggest customization for mounting and integration.

6. Limitations and Considerations

• Only five models are listed, covering a specific size range.
• Some parameters such as internal hole diameters and thread depths vary and must be matched carefully to application requirements.
• Weight and size increase with gear diameter, impacting handling and installation.

This summary extracts and clarifies the essential technical data for the Standard Series 3R20 external gears, facilitating selection and engineering integration.
