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

• Model Codes: E.1462.3R20.01.01, E.1635.3R20.01.01, E.1832.3R20.01.01, E.2045.3R20.01.01, E.2237.3R20.01.01
• Weight (kg): Ranges from 540 kg to 910 kg depending on model size.

2. Dimensional Parameters

The table includes multiple diameter measurements for both the outer ring and inner ring components of the gears, as well as bolt hole details and thread depths.

• Outer Ring Diameters: Outer diameter ranges from approximately 1462 mm to 2237 mm.
• Inner Ring Diameters: Inner diameters vary accordingly, with detailed measurements for inner and outer diameters of rings and bolt circles.
• Bolt Hole Details: Number of bolt holes varies between 12 and 16 depending on the model, with corresponding bolt circle diameters and hole diameters specified.
• Thread Depth: Thread depths are provided for the outer ring bolt holes.

3. Gear Teeth and Module

• Module: Consistent module value of 12 or 14 or 16 depending on the gear size.
• Number of Teeth: The number of teeth is specified for each gear model, ranging from 119 to 137 teeth.

4. Additional Mechanical Dimensions

• Dimensions such as bearing axis diameter, external and internal hole diameters, and ring heights (thickness) are included to provide comprehensive mechanical design data.
• Overall height (combined thickness of rings) is also specified for each model.

Summary of Critical Parameters

Recommendations and Usage Notes

• Ensure compatibility of bolt hole patterns and thread depths when selecting gears for assembly.
• Verify module and number of teeth to match mating gears for proper meshing.
• Consider overall height and ring thickness for installation space requirements.

This structured data supports design, manufacturing, and quality control processes for external gears in the 3R20 series.
