Selecting a worm gear lubricant

To compete in the marketplace, engineers across all industries are being tasked with increasing gearbox efficiency. Modern designs therefore must achieve high-power transfer without...

Power Skiving with integrated cutter resharpening

Gear manufacturing by Power Skiving takes the traditional approach: After a cutter has reached its maximum wear, the operator changes the cutter, adjusts the...

A new approach for the calculation of worm shaft deflection in worm and crossed...

Worm gear drives are characterized by a simple design, which allows the realization of a high gear ratio within one stage. Furthermore, they are...

The commonalities and differences between helical ‘low-tooth-count gears’ and ‘multiple-start worms’

The article deals with geometrically-accurate worm gear pairs that feature line contact between tooth flanks of a worm gear and thread surfaces of a...

Multi-sensor metrology advances

Demand for accurate gears delivered on tight schedules is increasing. To keep pace, technology is continually advancing, enabling manufacturers to do more in the...

Documenting defects with greater accuracy

We are in an era where modern technology and automation are rapidly evolving and pushing out conventional hand-operated tools. The LED magnifying glass lamp...

Finding the ideal materials for gears

When designing an individual gear or a gear train, the choice of material will either be the primary factor on which the gear geometry...

Nonlinear dynamic characteristic analysis of a coated gear transmission system

Coatings can significantly improve the load-carrying performance of a gear surface, but how they affect the vibration characteristic of the system is an urgent...

Electrification in the automotive domain

In the modern world, there is no limit to the varieties of vehicles available in the market. From variations in engine types such as...

New standardized calculation method of the tooth flank fracture load capacity of bevel and...

Bevel and hypoid gears are widespread in automotive, industrial, marine and aeronautical applications for transmitting power between crossed axles. Future trends show that the...

‘Never say: It’s not my job’

After an evening of dinner and a meet-and-greet with his wife and children, one of Tom Kelly’s dear friends and colleagues sat the senior...

Chamfering of cylindrical gears: Innovative new cutting solutions for efficient gear production

Cylindrical gear chamfering and deburring is a rather “unloved” process that adds cost but without delivering readily apparent improvements in gear quality. However, the...

Power skiving: High quality, productivity, and cost efficiency in gear cutting

Like electric mobility, the technology of power skiving has been known for more than 100 years and, with the availability of 5-axis machining...

Stability and flexibility: A new paradigm for eBeam metal AM

Additive manufacture (AM), and in particular the powder bed fusion (PBF) process, has offered hope to manufacturing industries needing to meet the environmental and...

Leveraging the complementary strengths of orbitless and planetary drives

An orbitless drive is a novel, fixed-ratio, epicyclic drive that includes a second carrier in place of a ring gear. It has been shown...

The benefits of splines

What is a spline? According to the American Heritage Dictionary of the English Language, a spline is defined as: Noun: 1a) Any of a...

Bringing forging equipment online to meet expanding production requirements

When forging operations need to expand production to meet increased demand for existing parts or to add new product lines, selecting from the available...

Rapid and precise manufacturing of special involute gears for prototype testing

Due to the steadily increasing demands on the power density of mechanical transmissions, gears with special geometries are increasingly coming into focus and, therefore,...

Optimization of rack and pinion for offshore jack-up applications

Liftboats or jack-up oil rigs are essential for the oil and gas industry. The subsystem (rack, pinion, gearbox, and brake) within the system lift...

Tooth root testing of steels with high cleanliness

The power density of gearboxes is continuously increased through different research activities. Besides new material developments, steel cleanliness comes to the forefront in order...
