Standard Series 1R25 External Gear Specifications

This document provides detailed technical specifications for the Standard Series 1R25 external gears. The data is organized in a tabular format listing various parameters for each gear model.

Key Parameters and Definitions

• Weight (kg): Mass of the gear.
• Outer Diameter (mm): The external diameter of the gear ring.
• Outer Ring Invoice Diameter (mm): Diameter related to the outer ring's invoice or reference.
• Outer Ring Inner Diameter (mm): Internal diameter of the outer ring.
• Inner Ring Outer Diameter (mm): External diameter of the inner ring.
• Inner Ring Invoice Diameter (mm): Diameter related to the inner ring's invoice or reference.
• Inner Ring Inner Diameter (mm): Internal diameter of the inner ring.
• Ball Track Diameter (mm): Diameter of the ball bearing track.
• Outer Ring Bolt Circle Diameter (mm): Diameter of the bolt circle on the outer ring.
• Inner Ring Bolt Circle Diameter (mm): Diameter of the bolt circle on the inner ring.
• Outer Ring Hole Diameter (mm): Diameter of the holes on the outer ring.
• Inner Ring Hole Diameter (mm): Diameter of the holes on the inner ring.
• Thread Depth (mm): Depth of the thread on the gear.
• Number of Bolt Holes: Count of bolt holes on outer and inner rings.
• Ring Height (mm): Thickness of outer and inner rings.
• Overall Height (mm): Total height of the gear assembly.
• Module: Gear module indicating size of teeth.
• Number of Teeth: Total teeth count on the gear.

Summary of Gear Models

Critical Information and Recommendations

• The module is consistently 10 or 12 across models, indicating standard tooth sizing.
• The number of teeth varies with gear size, affecting gear ratio and torque transmission.
• Dimensions such as bolt circle diameters and hole diameters are critical for mounting and assembly compatibility.
• Ring heights and overall height are important for fitting within mechanical assemblies.
• Weight increases with gear size, impacting handling and installation.

This structured data supports selection and engineering design decisions for applications requiring external gears in the 1R25 series.
