Through loaded tooth contact analysis of two applications, this paper demonstrates that crown gears can match bevel gear load capacity while offering meaningful advantages in weight reduction, axial-force-free pinion mounting, and assembly simplicity.
An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld exploring the mathematics behind conjugate bevel and hypoid gears—from the fundamental laws of gearing and the conditions for perfect conjugacy to why real-world power transmissions require deliberate crowning rather than theoretically exact conjugate designs.

20NiMo9-7 alloy achieves up to 48 percent higher fatigue strength than conventional carburizing steels in the as-carburized condition, eliminating the need for shot peening and grinding in automotive gear applications.
.
Water spray quenching achieves heat transfer coefficients up to 4,000 W/(m²K)—nearly double conventional oil quenching rates—enabling potential material substitution and tailored quench intensity for complex gear components.
.
This study investigates how manufacturing-related geometry deviations in the tooth root area affect gear bending strength calculations, demonstrating that accounting for measured tooth contours rather than nominal geometries is essential for accurate material comparisons in fatigue testing.

Variable loads resulting from a working process, starting process, or operation near a critical speed will cause varying stresses at the gear teeth of a drive system. The magnitude and frequency of these loads depend upon the driven machine, the motor, the dynamic mass elastic properties of the system, and other effects.
2023 is shaping up to be our planet’s hottest year on record, and the wind energy industry is feeling the heat. The GWEC (Global Wind Energy Council) says that the rate of wind turbine installations will need to quadruple globally by the end of the decade if we’re to achieve the IRENA’s (International Renewable Energy Agency) goal of net zero carbon emissions by 2050—and keep the average annual temperature worldwide from increasing more than the predicted 1.5° C. Fortunately, “net zero” commitments are gathering global momentum. Before year’s end, total global windpower is expected to reach a historic milestone of 1 TW of installed capacity, eliminating 1.2 billion tons of CO2 annually, roughly the equivalent of all the carbon emissions of South America.
On the surface, it may not seem like the gear inspection industry has changed much over the last few years. Shops still primarily use either machines that are dedicated solely to measuring gears, or multiuse Coordinate Measuring Machines (CMMs). And regardless of which machine they use, software serves as the backbone that supports their many diverse sensors.
The roots of heat-treating run deep within ASM (American Society for Materials) International, as its society was founded in Detroit in 1913 as The Steel Treaters Club. The heat-treating constituency of ASM created the Heat Treating Society (HTS) to provide focused leadership, communications, and service development to its network of worldwide membership of captive and commercial heat treaters, equipment manufacturers, researchers, governments, and technicians. To discuss Heat Treat 2023, the 32nd annual HTS Conference and Exhibition, Gear
Technology took a moment to catch up with conference chair Andrew Banka, vice president of Airflow Sciences Corporation. Heat Treat 2023 is colocated with IMAT and Motion + Power Technology Expo in Detroit, October 17–19.
The Intra SFTX twin-spindle single-flank testing system is engineered for advanced gear quality testing and NVH analysis of demanding e-drive gear applications. Combining Transmission Error (TE) and Torsional Acceleration (TA) measurements, it delivers fast, precise diagnostics and detailed order analysis, quickly identifies critical gear issues, enhances traceability, and helps prevent costly defects from reaching end-of-line (EOL) testing.
The 80PS Power Skiving and Hobbing Machine is specifically engineered for power skiving, hobbing, and profile milling of small internal and external gears. Configured specifically for the demands of humanoid robotic gear production, it delivers outstanding performance and process stability for gears used in strain wave, planetary, and cycloidal gearboxes, as well as other high-precision applications of comparable size — even when machining fine-pitch gears and thin-walled components.
Profile modifications on gears often mean additional dressing tools, extra costs, and longer lead times. With DIP (dresser-independent profile modifications), Liebherr has developed a generating grinding method that, for the first time, allows for profile modification during dressing using a profile dressing roll, thereby combining flexibility with short dressing times.
Discover how next-generation bevel gear metrology combines flank form, waviness, surface quality, and root geometry analysis in a single automated inspection cycle. Advanced software and standard probes deliver faster measurements, deeper diagnostics, improved process control, and enhanced gear performance.
Deburring gears is dusty, repetitive, and hard to staff. The OB7 cobot from Productive Robotics automates it with quick setup and no programming required. Consistent finish on every part, built in the USA. See the full cobot deburring package and request a quote.
Productive Robotics sets the new standard for simplifying robotic automation. OB7 ensures simplicity in use and versatility, easy automation of existing production and new set-ups, increased output, consistency, and quality. It emphasizes teaching the robot rather than programming. Productive Robotics' OB7 collaborative robots are currently used in many diverse applications due to their simplicity, capability, and affordability.
At IMTS 2026, Mitsubishi Electric Automation will feature live demonstrations of LoadMate Plus and ARIA, two pre-engineered robotic machine tending solutions designed to help manufacturers automate CNC mills and lathes with confidence, flexibility, and scalability. Automated machine tending enables longer spindle uptime, improved process consistency, and redeployment of skilled workers to higher-value tasks. Robotic tending also reduces unplanned downtime and supports lights-out or extended hours.
