The Past, Present and Future of Gear Manufacturing

June 1, 2014

The gear industry is full of storytellers. It's a niche market that boasts a remarkable cast of characters that have been sharing their stories with us for 30 years. In that time, the editors and staff of Gear Technology magazine have had the privilege to report the ins and outs of this highly-specialized industry. From technical articles to case studies and features, the main focus of this magazine has been to "provide a forum of discovery and innovation for you, the gear manufacturing industry." Our Publisher, Michael Goldstein, said as much in our inaugural issue of May/June 1984.

Calculation of Tooth Root Load Carrying Capacity of Beveloid Gears

June 1, 2014

In this paper, two developed methods of tooth root load carrying capacity calculations for beveloid gears with parallel axes are presented, in part utilizing WZL software GearGenerator and ZaKo3D. One method calculates the tooth root load-carrying capacity in an FE-based approach. For the other, analytic formulas are employed to calculate the tooth root load-carrying capacity of beveloid gears. To conclude, both methods are applied to a test gear. The methods are compared both to each other and to other tests on beveloid gears with parallel axes in test bench trials.

Gear Ratio Epicyclic Drives Analysis

June 1, 2014

It has been documented that epicyclic gear stages provide high load capacity and compactness to gear drives. This paper will focus on analysis and design of epicyclic gear arrangements that provide extremely high gear ratios. Indeed, a special, two-stage planetary arrangement may utilize a gear ratio of over one hundred thousand to one. This paper presents an analysis of such uncommon gear drive arrangements and defines their major parameters, limitations, and gear ratio maximization approaches. It also demonstrates numerical examples, existing designs, and potential applications.
