Straight‑tooth Bevel Gears

Product catalog summary
Introduction
This document offers technical specifications, formulas, and recommendations for designing and mounting straight bevel gears, including calculations for bearing forces, gear ratios, and mounting guidelines.

Specifications and Formulas
It details formulas for calculating individual and total bearing forces for gears and pinions, with a table of factors for gear ratios from 1:1.0 to 1:5.0, essential for determining loads on bearings with a 90° shaft angle.

Design Considerations
Highlights the use of bevel gears with crowned tooth bearings for their resilience to production and mounting errors, emphasizing limited tooth bearing to mitigate these effects.

Mounting Recommendations
Guidelines include using large shaft diameters and minimal distance from tooth center to bearing to reduce displacement under load, specifying minimum bearing distances and the importance of correct mounting distances, tooth bearing, and backlash.

Material and Manufacturing
ATLANTA bevel gears are made from heat-treatable steel Cf 53, with options for flame or induction hardening for increased strength, and lubrication recommendations are provided, designed for maximum load capacity per Gleason guidelines.

Conclusion
The document provides comprehensive guidelines for the design, calculation, and mounting of straight bevel gears, ensuring optimal performance and durability under various operational conditions.

This often requires overhung-mounting of the bevel gears. In order to keep the displacement of the tooth bearing under operational loads small, largest possible shaft diameters, minimal distance from tooth centre to bearing and a double-sided support of the gear are to be provided, if possible. To keep the moment of tilt small, the bearing distance "I" should not...
