Berg Compares Spur and Helical Gears

Mechanical design engineers planning a drivetrain typically have a range of component options to choose from, and many decisions will boil down to the specific application. When it comes to creating optimal torque output, rotational speed and direction, few decisions are as important in designing high performing gear drives as choosing the right gear for the job.

SEW-Eurodrive Helical and Bevel Gear Units Offer Sustainability and Efficiency

Digital data models and the latest calculation methods lay the foundations for a further improvement in the performance of Generation X.e. SEW-Eurodrive continuously factors the findings of field/test stand trials and simulations into its own calculations, thereby improving their accuracy and reliability. The mechanical and thermal design of the X..e series was once again precisely evaluated on this basis. In conjunction with the component optimizations already implemented in the past, this results in even higher thermal limit ratings, a much longer bearing service life, and higher nominal torques. Moreover, larger application angles are now permissible with the maximum overhung load.

Gear Industry Honors Frederic (Fred) Marlin Young (1943-2023)

Fred Young, 80, former president and CEO, Forest City Gear passed away on July 17, 2023. A graduate of Harlem High School, class of 1961, Young obtained his BA in English Literature from Rockford University, class of 1965, and went on to spend a year in the Navy Reserves. After spending nearly 40 years as an adventuring bachelor outdoorsman, he met the love of his life, Wendy Nutter, marrying her on the banks of the Wolf River on June 6, 1981. Fred’s greatest joys were his three daughters, whom he taught to always seek adventure, bestow kindness and generosity, treasure friendship, and work hard and play hard. Fred took over the family business, Forest City Gear, in 1967. Founded by his parents in 1955, Fred took the small mom-and-pop shop to a global level, leading the company to manufacture some of the world’s most difficult gearing for amazing end uses from NASA’s Martian rovers and space station to robotic arms and racing yachts.

Having a Ball: The Technology Behind the Ball Drop

More than a billion people around the world unite to ring in the New Year, their eyes set upon the glittering New Year’s Ball in Manhattan. Thousands are gathered at Times Square — the famed “Bow Tie” of Midtown — braving the December cold and peering through glasses with numerically shaped frames. Millions more tune in from their various screens at home.
With so much riding on its descent, the Ball, along with the mechanical and electrical systems responsible for its operation, must operate like clockwork.

FEM Analysis of the Load Distribution over the Face Width of Helical Gear Pairs Considering Deviations, Misalignments and Deformations

The load carrying capacity of spur gears may be calculated by ISO 6336 using influence factors. The face load factor considers the impact of the non-uniform load distribution over the face width. Even if the gears had perfect geometry, the load would not distribute uniformly along the contact lines. The face load factor depends on deformations of all parts of the containing gearbox and mainly of the teeth, gears and shafts as well as on manufacturing and assembly deviations.

Gear Design Effects on Performance of High-Speed Helical Geartrains as Used in Aerospace Drive Systems

The performance of high-speed helical geartrains is of particular importance for tiltrotor aircraft drive systems. These drive systems are used to provide speed reduction/torque multiplication from the gas turbine output shaft and provide the necessary offset between these parallel shafts in the aircraft. Four different design configurations have been tested in the NASA Glenn Research Center, High-Speed Helical Geartrain Test Facility. The design configurations included the current aircraft design, current design with isotropic superfinished gear surfaces, double-helical design (inward and outward pumping), increased pitch (finer teeth), and an increased helix angle. All designs were tested at multiple input shaft speeds (up to 15,000 rpm) and applied power (up to 5,000 hp). Also two lubrication, system-related, variables were tested: oil inlet temperature (160–250° F) and lubricating jet pressure (60–80 psig). Experimental data recorded from these tests included power loss of the helical system under study, the temperature increase of the lubricant from inlet to outlet of the drive system and fling-off temperatures (radially and axially). Also, all gear systems were tested with and without shrouds around the gears.
