FEATURES

Bourn & Koch, Inc.

Bourn & Koch continues to combine the most well-known brand names in the history of industrial machining with customer-driven solutions and the industry’s latest technology.

Bourn & Koch was founded in 1975 when Larry Bourn & Loyd Koch, prior employed at Sundstrand Machine Tool, set out to fill a niche of remanufacturing and retrofitting machine tools and to build specialty machines not being addressed by other large machine tool builders. Throughout its 40-year history, Bourn & Koch has continuously strived […]

Customer Success Stories

Two gear manufacturing companies — Croix Gear & Machining in Wisconsin and Columbia Gear in Minnesota — benefited from purchasing Gleason machines in order to fill their needs for increasing capacity, capabilities, and technologies.

Technology Transformation at Croix Gear & Machining Croix Gear & Machining leverages Gleason’s total solutions package to exceed customer expectations for spiral bevel gear quality and delivery. When Wisconsin Governor Scott Walker criss-crossed his state earlier this year to pitch Wisconsinites on his ambitious “Blueprint for Prosperity” plan for tax relief and worker training, he […]

Gear Tooth Root Stresses of a Very Heavily Loaded Gear Pair

In this case study, specialized contact analyses and finite element methods were used to study gear tooth stresses of the space shuttle orbiter’s body flap actuator gears.

For aerospace applications, there is a high premium on minimizing the mass of all components while meeting operational and safety requirements. Gears for space shuttle orbiter actuators were specified to meet safety factor requirements for fatigue life, yield, and ultimate load carrying capacity [1]. Analytical predictions of safety factors for gear teeth with respect to […]

Optimizing Innovation in Driveline Design Processes

Simulation technology is driving innovation in gear and drivetrain design fields with an approach that moves problem-solving earlier in the process.

In the driveline industry, innovation can only be achieved when the use of new or novel technologies or methods are applied to design and development goals. Innovation also means harnessing practical ways to support business goals and deliver higher quality products faster, more efficiently, and with a lower cost. While design and manufacturing methods improve […]

Flame Hardening

Flame hardening is a viable, cost-efficient solution for heat treating difficult gear designs and for lower production volumes. Here, an overview on flame hardening, as well as spin hardening and robotic gear hardening, is discussed.

Heat treating gears increases their durability and strength, and there are many heat treating options to suit different applications. To achieve the best return on investment, factors that should be considered include production volume, gear or shaft design, and hardness pattern and depth specified for the parts. Also, determining the number of parts that will […]

Effective Methods for Checking Grinding Quality

Grinding affects the performance of a gear component, therefore it’s important to optimize the grinding process and eliminate defective parts before final assembly.

Grinding is often the last process in the manufacture of high-quality, high-load-bearing gearbox components. High-load-bearing gears are hardened for greater strength and ground to reach tight dimensional tolerances. But too much heat from the grinding process can relax beneficial compressive stresses, soften a surface that should be hard, and, in the extreme, produce tensile stresses […]

Isotropic Superfinishing

Surface finishing technology, including the specific technique of isotropic superfinishing, is gaining interest in the gear industry due to its importance in maximizing component performance.

Increasingly stringent operational requirements from customers coupled with enhanced global technical standards have heightened the focus of gear designers on a wide array of parameters that historically would have been of secondary consideration; one such design parameter is surface finish. This article is the first in a short series that will cover a specific subcategory […]
