Company Profile: Penn Reels

A recognized best-in-class fishing reel product line, a dedicated pursuit of advanced gear technology, and an inspiring 80-year history has helped Penn Reels become a key player in the industry of one of America’s favorite pastimes.

The beginning of Penn Reels is not only a story of an American dream, but also a story of a fishing tackle manufacturer that revolutionized saltwater angling. It started in 1922 when Otto Henze, a 25-year-old machinist, moved from Germany to the United States and began working for the Ocean City Reels Company in Philadelphia. Ten […]

Advantages of Direct Gear Design For Automotive Polymer Gear Drives

Direct Gear Design, a development process where gear parameters are primary and tool parameters are secondary, maximizes performance of plastic gearing by compensating for polymer property limitations.

Invention of the gear-generating machining process that uses the gear rack shape tooling cutting edge (as shown in Figure 1) established basic principles of traditional gear design. Parameters of the tooling gear rack such as the profile (or pressure) angle, addendum, whole depth, and fillet radius proportions are standardized and used as input gear design […]

An Improved Load-Equalizing Means For a Multi-Flow Gear Train

A method for equal power sharing in planetary gearboxes is proposed based on the use of elastic absorbers of manufacturing errors.

This paper relates to the load-equalizing capabilities of planetary gearboxes, and more generally, addresses the load-equalizing capabilities of multi-flow gear trains, that is, gear trains that feature two or more flows of transmitted power. Typically due to manufacturing errors, displacements under operating load, or other factors, planetary pinions share power disproportionately. Enhanced accuracy in the […]

Actual Tooth Contact Analysis of Straight Bevel Gears

When measuring with coordinate measuring machines, a new proposed approach is utilized to capture deviations from spherical involute bevel gears; these deviations are then used in tooth contact analysis.

Straight bevel gears are the simplest type of bevel gears that transfer power between intersecting axes [1]. They are widely used in low-speed applications or static-loading conditions. Differential gears are one such application where the speed is very low and the load type is mainly static. There are still several traditional applications of straight bevel […]

Gear Surfaces and Operational Performance

While the surface of a gear comprises only a fraction of the component’s overall mass, its physical properties impact the performance of that component in operation.

In the search for increased performance and durability, gear and bearing design has sought to make use of improved steel grades combined with enhanced heat treatment techniques. The aim of these improvements is to prevent irregularity or impurity failures of the bulk metal substrate. This advancement in material preparation has enabled design limits to be […]

Gear Expo 2015 Recap

At AGMA’s Gear Expo in Detroit, there were many signs of how the machines in the gear industry have changed.

Most of you know that the gear production machines today are much more capable and productive than those of even 10 years ago. However, I was impressed as to how far those machines and others have come. Gear Expo 2015 offered an opportunity to see them in action. Since the mid-1980s, gear machines of all […]

Convection Phase

Velocity, boundary layer, and turbulence in quenching have implications on heat transfer in batch and continuous furnaces.

Anyone who has attended a technical seminar on quenching has heard of the three stages of oil quenching: the vapor phase, the film boiling phase, and, finally, the convection phase. We’ve also learned that the first and last are the slowest forms of heat transfer. And we’ve been told that in high pressure gas quenching […]

Trend Talks: Year in Review

The U.S. gear manufacturing industry is poised to enter a new era of strength in 2016 due to growth and developments over the past year.

In 2015, we saw strides being made in several areas, including an increase in research and development efforts paired with a demand for more funding and technological investments. There have also been new and revised standards created and implemented by AGMA, ANSI, and ISO. One example of such a standard is the revised ISO 9001 […]
