Fundamentals of Worm and Crossed Axial Helical Gearing - February 18-20, 2020

  • Registration Closed

Course Description:

Provides an introduction and emphasize the differences between parallel (the experience base) axis and worm and crossed axis helical gears. Describe the basics of worm and crossed axis helical gears, their fundamental design principals, application guidelines and recommendations, lubrication requirement, a discussion of accuracy and quality and summarize with a brief review of common failure modes.

Learning Objectives:

After attending this session, you will be able to;

Define the basic differences between parallel axis, common crossed intersecting axis and worm / wheel and crossed axis helical gears

Interpret and discuss the design and applications specifics as they apply to worm / wheel and crossed axis helical gears

Assess lubrication, cooling and support requirements for worm / wheel and crossed axis helical gears

Explain the cause of a particular failure of a worm / wheel or crossed axis helical gear pair, as a function of application or use
