The Doctor Is In

Inside Luftex’s five-pillar approach to gearbox repair

Most gearbox repair follows a familiar sequence. A unit shows up damaged, the shop measures what’s worn, makes replacement parts, reassembles, and ships it back. Scott Franks, P.E., spent decades inside that world at Lufkin Industries and came to believe it wasn’t enough.

Design Principles of Bevel Gears: Rationale for Zero Sum Profile Shifts and Generating Gear Choices

This article demonstrates why bevel gears are designed with a zero sum of profile shifts—showing that independent shifts merely replicate what a modified pressure angle already achieves—and explains the practical benefits of using conical generating gears for tooth profile crowning.

Design Method of System Tolerances in Cylindrical Gearboxes for Cost-Efficient Optimization of the Excitation Behavior

The article proposes a method to optimize cylindrical gearbox tolerances by balancing gear noise performance and manufacturing costs using modeling, analysis, and meta-model-based optimization.

Smart Alloying Eliminates Manufacturing Steps in Automotive Gears

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.

Conjugate Bevel and Hypoid Gears

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.

Design

Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes

Grinding

The world of bevel gear grinding is a complex topic. How do you determine which grinding and dressing parameters to select for a desired surface finish? What type of grinding wheel should be used? What type of dresser should be used? How do all these factors affect the gear noise and quality levels? These are some questions that will be addressed in this article.

Inspection

When electric drives are used in vehicles, the masking effect of an internal combustion engine disappears, allowing the noise behavior of the transmission to take center stage. At the same time, peak power and torque increase, engine speeds increase, and power must be transferred optimally in both directions due to the regenerative braking system. Conventional design parameters remain important, however: The build space is limited, durability must not be compromised, and the product must still be cost-efficient. Optical metrology as part of a hybrid measurement concept helps to overcome all these challenges.

Heat Treating

By understanding customers’ manufacturing and heat-treatment processes, Ipsen identifies pain points and develops IIoT and AI-driven solutions that improve operational efficiency.
