Technical Specification Summary for STANDART3SERİ31B203L3 Internal-External Gear

Overview

This document provides detailed dimensional and technical specifications for a series of internal-external gears identified by model codes such as LI.0518.1B20.01.01 through LI.1198.1B20.01.01. The data includes weight, diameters, bolt hole details, thread depth, ring thicknesses, and module parameters.

Key Parameters and Dimensions

• Weight (kg): Ranges from 27 kg to 81 kg depending on the model size.
• Outer Diameter (mm): Varies from 518 mm to 1198 mm.
• Outer Ring Diameter and Bolt Circle: Outer ring diameters and bolt circle diameters are specified, with bolt hole counts and sizes consistent across models.
• Inner Diameter (mm): Inner diameters range from 326.5 mm to 985.6 mm.
• Thread Depth and Bolt Holes: Thread depth is consistently 46 mm; number of bolt holes varies between 5 and 8 depending on the model.
• Ring Thickness (mm): Outer and inner ring heights are specified, generally 46 mm for outer ring height and 56 mm for inner ring height.
• Module and Number of Teeth: The module is 3 for all models; the number of teeth varies from 67 to 125.

Dimensional Details

The table includes multiple diameter measurements for both inner and outer rings, such as outer ring diameter, outer ring invoice diameter, inner ring outer diameter, and inner ring invoice diameter. These precise measurements ensure compatibility and fitment in mechanical assemblies.

Bolt Hole Specifications

• Number of bolt holes on the outer ring ranges from 5 to 8.
• Bolt hole diameters and bolt circle diameters are standardized with M12 threads and 18 mm hole diameters.
• Internal and external hole diameters are specified for both inner and outer rings to facilitate mounting.

Recommendations and Usage Notes

The consistent module and thread depth across the series suggest interchangeability within certain size ranges. The detailed dimensional data supports precise engineering design and quality control for applications requiring internal-external gear assemblies.

Summary

This technical data sheet is essential for engineers and designers working with the STANDART3SERİ31B203L3 gear series, providing all critical dimensions, weights, and mechanical parameters necessary for selection, installation, and maintenance.
