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...

Incorporating 3D artificial intelligence with AR and VR technology

The race continues between the world’s largest tech leaders and companies to see which one will prevail and power the next generation of tools,...

A comparison of an analytical and FEA approach in determining thermal lead correction for...

For high-speed applications, gears of large dimensions and high-power density are used. Temperature distribution in those rotors is much different in operation as compared...

Tooling & Workholding: Software thought backwards

There are already an infinite number of different gear geometries. Nevertheless, engineers are constantly coming up with new variants. For example, gears are becoming...

Inspection & Metrology: The growing role of metrology in EV production

It has become abundantly clear that not only are electric vehicles (EVs) becoming more prevalent on the roads but that almost all automotive companies...

Heat treatment of gears

Often the options of heat treat may feel pre-defined when looked at from a gear designer’s perspective. There are options, but both gear designers...

Inspection & Metrology: Overcoming metrology bottlenecks in additive manufacturing

Undoubtedly there are many benefits associated with the use of additive manufacturing (AM) as a production technology. Across industries, manufacturers exploit the fact that,...

Build resilience by monetizing value

Unforeseen disruptions, market fluctuations, and macroeconomic issues. The last year alone has exposed the unpredictable nature of the market and supply chains. Even new competitors...

Tooling & Workholding: Patented considerations in High Torque tooling

It is common knowledge in the CNC manufacturing community that if you use V-Flange tooling, you use retention knobs, which are the critical interface...
