Standard Series 1R25 Internal Gear Technical Specifications

This document provides detailed technical specifications for the Standard Series 1R25 internal gears, including dimensions, weights, and key parameters essential for design and manufacturing.

1. Gear Identification and Weight

• Each gear is identified by a unique code (e.g., I.1232.1R25.01.01).
• Weight ranges from 190 kg to 240 kg across the series.

2. Dimensional Parameters

The table lists multiple diameter measurements critical for gear fitting and assembly:

• Outer Ring Outer Diameter (De): Ranges from 1120 mm to 1320 mm.
• Outer Ring Inner Diameter (Di): Ranges from 960 mm to 1140 mm.
• Inner Ring Outer Diameter (Ui): Ranges from 1052 mm to 1252 mm.
• Inner Ring Inner Diameter (Li): Ranges from 960 mm to 1140 mm.

3. Bolt and Hole Specifications

• Number of bolt holes on outer ring: 36 to 40.
• Number of bolt holes on inner ring: 64.
• External hole diameters and bolt circle diameters are specified for both inner and outer rings to ensure proper mounting.

4. Thickness and Height

• Outer ring thickness varies between 10 mm and 12 mm.
• Inner ring thickness is consistently 73 mm.
• Overall height is approximately 96 mm to 110 mm depending on the gear size.

5. Module and Number of Teeth

• Module is fixed at 10 for all gears.
• Number of teeth varies from 97 to 110, corresponding to gear size.

Summary of Critical Parameters

Key Recommendations and Notes

• Ensure compatibility of bolt hole patterns and diameters during assembly to maintain structural integrity.
• Thickness and height parameters must be respected to guarantee proper gear meshing and performance.
• Module and number of teeth are critical for gear ratio and should be selected according to application requirements.

This structured data supports design engineers in selecting and integrating the 1R25 internal gear series into mechanical systems.
