An in-depth explanation of 4 types of metering pumps such as gear, piston, screw and progressive cavity.

Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect -- showing that evolution developed interlocking cogs long before ...

Functioning 'mechanical gears' seen in nature for first time Date: September 12, 2013 Source: University of Cambridge Summary: Previously believed to be only human-made, a natural example of a ...

This scanning electron micrograph image is of the intermeshing gears. This image relates to a paper that appeared in the 13 Sept., 2013, issue of Science, published by AAAS. The paper, by Malcolm ...

New York-based Proxy Design Studio has given Gizmodo a first glimpse of its incredible, 3D-printed spherical gear called the Mechaneu, equal parts tactile toy and mechanical sculpture, a mind ...

The Kaman K-MAX has intermeshing rotors eliminating the need for a tail rotor. These opposite-spinning rotors lend the K-MAX a natural tendency to hover, making it more stable. The K-MAX is ideal ...

Increased complexity of materials prioritizes processability. Demand for superior compound quality is driven by rotor performance. HF Mixing Group’s PES5 rotors are the “standard” for intermeshing ...
