Hydraulic workholding takes hold

In the brave new world of smart factories, Internet 4.0 and highly automated machines and cells, workholding rarely gets top billing. It’s surprising that...

Still Stuck with Hand Deburring?

No blueprint ever revealed, nor engineer ever designed, a part with burrs. It is only after a process is selected for making a part...

Industrial gear lubricants face formulation challenges

Gears transmit motion from one shaft to another or from a rotating shaft to a reciprocating element. Gears transmit power, change speed, change force...

Advantages of a dual-screw H-Frame broaching machine

Like any industry, in the machine-tool industry, the needs of the market drive new designs and the development of new technologies. Naturally, everyone wants...

Streamlining safety for high-speed/small-footprint milling machines

Safety in design is critical to CNC milling operations end products as well as to the machine’s profitability. As the trajectory of today’s new...

Integrating Non-Contact Metrology in the Process of Analysis and Simulation of Gear Drives

Speed and accuracy are critical factors for gear inspection. The faster the inspection process, the larger number of gear units can be inspected. The...

Design features of perfect gears for crossed-axes gear pairs

Gearings that operate on crossing axes of rotation of a gear and a mating pinion have been known for centuries. Common sense and accumulated...

Magnetic Barkhausen Noise as an Alternative to Nital Etch for the Detection of Grind Temper...

The detection and prevention of grinding burn is critical to the production of ground gears of all types and sizes. Overheating during grinding, or...

Grading the strength of steel

Vehicle manufacturers are faced with a difficult task of significantly improving fuel economy and safety while maintaining competitive position in the market. This can...

Measuring Tooth Flank Roughness

Gear performance has continuously increased over the past two decades. Improvements in metals, heat treatments, geometry, and lubrication are just a few of the...

The Root Cause for Gear Noise Excitation

This article is about noise excitation and vibration generation in gear drives when the gear drives operate. It is shown that transmission error is...

How Polyketone Polymers Improve Gear Performance

Engineers have been using thermoplastic resins to produce gears used in assemblies for the automotive, appliance, business equipment, and other market segments for many...

Psychoacoustic Methodology for the Noise Reduction of Bevel Gears

The relationship between FFTs and gear quality as well as gear noise is investigated with some surprising conclusions, which leads to the discovery of...

The critical role of deburring

Autonomous steering and brake systems, hydro-pneumatic chassis, or radically improved gas mileage — these buzzwords represent a technological change that is triggering a domino...

Heat treating low alloy PM steels

Tempering is a heat-treatment technique used to improve the strength, ductility and toughness of hardened carbon steels. Tempering occurs by heating the steel to...

Calculation of Tooth Flank Fracture Load Capacity

1: Introduction Due to improved material qualities, new surface finishing methods and increased heat-treatment process reliability, flank surface damages, such as pitting or micropitting,...

Advances in the Production of Double Helical Gears

Double helical gears (herringbone gears) are characterized by a symmetric arrangement of two identical gear teeth with exactly opposite helix angles. As a result...

Flexibility is Key to Aftermarket Success

Staying lean and profitable has always been a challenge for aftermarket gear manufacturing. Expedited delivery demands, legacy product support, unpredictable product volumes, limited warehouse...
