Involute Spline Design and Rating—Winter

January 17–18—Live Virtual Training

This course will address both geometry and rating of involute splines of various types. The types of spline joints and their applications will be discussed. Spline configuration variations, including half depth, full depth, and special function designs, will be addressed. Both fixed and flexible spline configurations will be examined in terms of usage and design. Lubrication methods, including grease, oil bath, and flowing oil, as well as coatings appropriate for various spline applications, are examined. Shear and compressive stress rating methods are discussed with analyses methodology presented in both equation and graphical methodology via various rating charts.

Design Basics for Spur and Helical Gears—Winter

February 13, 2024—Live Online Course

Learn how to develop and understand customer gear drive application specifications and target performance expectations. Review, calculate, and select basic gear terminology variables and design parameters that define tooth bending and contact rating safety factors on two real-life examples. Learn how to optimize gear fatigue Safety Factors for a given target design life and fit new gear designs and ratios into existing center distance using profile shift. Use commercially available software to develop gear geometry factors, calculate, and optimize gear set power density and performance. Review common gear failure modes if the design or final accuracy does not meet application requirements. Discuss the time and cost of more than 20 other gear drive component functions and drive development steps through prototypes to shipment of compliant assembled production drives. There will be an opportunity to discuss gear design challenges that may be unique to participant industries.

Supplier Insight: Variable Compression Ratio Technology from Gomecsys

Automotive Powertrain Technology International

The use of roller bearings helps to optimize the backlash of the gears, which is important for NVH. The patented gear drive system rotates the eccentric at half the speed of the crankshaft, which means that the roller bearings on the inside and outside of the eccentric both run at half the crankshaft speed. This is essential to keep the total engine friction levels low.

Hyundai, Kia Unveil Revolutionary New “Uni Wheel”

Winnipeg Sun

Rather than using CV joints, the Uni Wheel hub is attached directly to the shaft of the electric motor, and contains a planetary gear set that rotates a ring gear that turns the wheel, driving the vehicle. The reduction gears normally found in the electric motor—in effect, its transmission, which regulates the amount of power sent to the wheels—are inside the wheel hub.

MingYang Produces First 18 MW Offshore Wind Nacelle

REVE

Chinese wind turbine manufacturer MingYang Smart Energy has successfully produced its first 18 MW offshore wind turbine nacelle. The nacelle, which houses important components such as the gearbox, generator and control systems, is an integral part of offshore wind turbines. With this achievement, MingYang has joined a small group of companies capable of producing these high-powered nacelles. This breakthrough marks a significant step towards scaling up offshore wind technology and achieving the ambitious renewable energy goals set by several countries.

Additive Manufacturing Outlook 2024, the Argument for Optimism

all3dp.com

The sky is not falling. Despite the low number of product launches in 2023, low OEM stock prices, some notable company consolidations (and attempts), and a sluggish economy affecting spending, the AM market is still expected (by the overwhelming majority of analysts*) to grow at around 20% in 2024 and, more importantly, interest in and application of 3D printing has never been higher.

EV Transition Requires Patience in 2024

Automotive News

Even as elements of the electric vehicle ecosystem continue to fall into place, EV hesitation will be a prominent storyline this year. We urge industry leaders to remember that patience is paramount. Most EV goals are tied to 2030 or beyond, and the auto industry rarely flips quickly. Toward the end of 2023, automakers responded to the slowing pace of EV growth by delaying vehicle launches, cutting production and canceling EV development partnerships. To be clear, EV sales are growing. They surpassed a million in the U.S. last year, up from about 700,000 in 2022, according to J.D. Power. It's the speed of growth that's slightly sagging.
