Another breakthrough in power skiving

For the past decade, Gleason has been building power-skiving machines at its Gleason-Pfauter facility in Ludwigsburg, Germany. As the many benefits of this technology...

Equipment-as-a-service: Understanding all the moving parts

By this point, those within the industrial market have likely heard the buzz surrounding equipment-as-a-service (EaaS). This model has been around in one form...

Transient friction and wear simulation of worm gears during running-in

The load capacity of worm gears strongly depends on the size of the contact pattern. Worm wheels are often manufactured by using an oversized...

Combined lubrication of surface texturing and copper covering for a broaching tool

The broaching tool is an efficient and precisely heavy-loaded metal-cutting tool, widely used in the mass production of key components related to the aerospace...

Integrated optimization of gear design and manufacturing

The word “optimization” is becoming fashionable, also with regard to gear design. It is applied to both macro-geometry and micro-geometry. The approach can be...

Modeling tools for gear design and failure prevention

Evidence for the production of toothed wheels, better known as gears, can be traced back as early as the third century BCE . Over...

In gear with metrology

The gear is one of the most widely used manufacturing parts in the world. The number of real-world applications of gears is nearly limitless:...

Comparative study of the usage of SAE 8620 and EN 36C in an automotive...

An automotive differential gearbox is a critical component of the powertrain involved in the transmission of power and its appropriate distribution to the wheels....

Case study: Heading to the High Torque© finish line

More than most industries, today’s aerospace, defense, and automotive-component manufacturing is challenged with machining a lot of exotic alloys and hard metals. This can...

Service life of cylindrical and bevel gears under variable load and stresses

Transmissions are usually loaded by variable external loads under real operating conditions. The decisive load for a gearbox is in most cases the applied...

Comparison of strength ratings of plastic gears by VDI 2736 and JIS B 1759

The demand for strength ratings for plastic gears has been consistently increasing. However, there are no international standards such as ISO, DIN, or AGMA,...

Women in manufacturing: Diversifying the industry

You don’t have to go very far back in time to find a point where the role of women in the manufacturing sector was...

Latest advances in chamfer hobbing

While not considered a “value adding” process such as hobbing and fine finishing, cylindrical gear chamfering and deburring are getting the recognition they have...

Deburring with CNC machining

Delta Machine Company, LLC — based in Huntington Beach, California — is a machine shop specializing in complex, tight tolerance parts made of titanium,...

Detecting cracks in PM green products using laser vibrometry

Cracking of green parts in powder metallurgy (PM) is a big concern in the PM industry. Detection of cracks in green parts before sintering...

Metallic glass gears up for ‘cobots,’ coatings, and more

Where are the robot assistants we were promised? For all the space that robots have occupied in the popular imagination for the last hundred...

Formulating load-sharing behavior in epicyclic gears for wind turbines

In an ideal epicyclic gear set, every parallel gear path transmits the same amount of torque. However, it is well known that certain manufacturing...

Specifying surface texture parameters – tricks and techniques

There are many different ways that designers specify surface texture parameters for their parts. Some specifications are good, some not so good. Some are...

Design of a double spiral bevel gearset

It is known that bevel gears are used to transmit rotary motion and torque between intersected axes in case there is no possibility of...

The advantages of pulse plasma nitriding

In the gear manufacturing industry, when case-hardening, tempering, or nitriding the surface of steel, whether for gears or gearboxes, the options have traditionally included...
