Brevini Gear Systems

Brevini Gear Systems, otherwise known as Brevini Wind USA, is a major contender in the ring of custom gear manufacturing. Although they still participate in the wind industry, their focus is serving the precision custom gear and gearbox market.

Brevini Power Transmissions began in 1960 in Reggio Emilia, Italy, by the three Brevini brothers—Lucciano, Renato, and Corrado. In 1964, Renato engineered, produced, and successfully tested his first gearbox. This development would later propel the three brothers into the planetary gear business. The 1980s were a time of growth for Brevini. Following the death of […]

Slim Profile Peripheral Cutting Tool Using Stick Blades

Peripheral cutter heads are utilized to machine bevel and cylindrical gears and basic milling operations on universal mills or five-axis machines. However, in the new cutter system discussed below, all other surfaces can be made with open tolerances.

Introduction Peripheral cutter heads are used for the machining of cylindrical and bevel gears as well as for general milling operations on universal mills or five axis machines. Most peripheral milling cutters are solid cutters, consisting of one piece of mostly high-speed steel. Other peripheral cutter designs utilize carbide inserts, which are mounted or brazed […]

If Necessity is the Mother of Invention, Customer Need is the Impetus for Design Evolution

Plato once wrote that necessity is the mother of invention. In the realm of workholding for gear manufacturing industry, this means innovation is the basis for constant improvement and concept evaluation.

Good quotations can sum up the jewels of life’s wisdom. They often come from people with significant and prolific accomplishments that impact our collective history and culture.  Even in the manufacturing world concepts from quotes and proverbs get incorporated into the fabric of our thinking and methods. The phrase “Necessity is the Mother of Invention” […]

Influence of Central Members Radial Support Stiffness on Load Sharing Characteristics of Compound Planetary Gearsets

In this study, a non-linear dynamics model of Ravigneaux compound planetary gearsets which adopts the intermediate floating component, is set up based on concentration parameter. Reducing the radial support stiffness of the central members helps improve the load sharing performance of the system.

Abstract In this study, a non-linear dynamics model of Ravigneaux compound planetary gearsets which adopts the intermediate floating component is set up based on concentration parameter.  By considering the position errors and eccentric errors, the dynamic load sharing factors of the gearsets are calculated. The relationship between central members radial support stiffness and the dynamic […]

History of Bending Fatigue, Part I

Even after more than a century of bending fatigue investigation, there is still much to be learned.

Bending fatigue life is a principle concern in all wrought and powder metal gearing and all mechanical power transmission components. It is also a concern in polymer gears when the mode of failure is not wear. The first part in this series investigates the historical milestones underlying the study of metal fatigue. The next part […]

Looking at a Print

When quoting a job or setting a job up for production, here are a few tips to consider when looking at a print. Getting from A-Z without hiccups is the best way to ensure your profitability.

Gears are hard to make. They come in all shapes and sizes and are made out of a variety of materials. Our customers dream up these things that cause nightmares for the faint of heart. So, let’s start at the beginning when we generally get our first look at the print—quoting. You open the email […]

Heat treating is an energy hog where three energy sources find application: natural gas, electricity, and fuel oil

A conundrum exists in that natural gas, coal, and fissionable metals are used to make electricity and, in some shape or form, electricity is used to produce natural gas, coal, and crude oil. Fracking shale requires motor driven pumps to drive mud into the ground a push natural gas and crude back to the surface. […]

How a single platform approach facilitated the shift to complex part manufacturing for aerospace and defense

Ahead of the recession, Smiths Machine did what many machine shops were doing at the time. They were riding the wave of automotive parts production and doing seemingly fine until the massive downturn came. The automaker bankruptcies left many machine shops vulnerable to overseas competition, and a once well-oiled machine tool business model now seemed […]
