Schaeffler acquires precision gearbox maker Melior Motion 

by Leave a Comment

Schaeffler, a billion-dollar German company which supplies bearings and other components to the automotive and aerospace industries, has signed an agreement to acquire all of the shares of Melior Motion.

The acquisition of this supplier of precision gearboxes for robotics and other applications in automation expands the robotics portfolio of the Schaeffler Group’s industrial division.

As automation of simple, repetitive tasks as well as complex mounting and manufacturing processes is progressing rapidly, Schaeffler’s industrial division is expanding its position as a supplier for robotics components and systems.

This component could profoundly change robots and other machines in the future

Pictured above, in exploded view, is a machinery component called the “LiveDrive”. It’s covered by a variety of patents and has been described as “revolutionary” because it could – believe it or not – change the world. 

First unveiled about three years ago, the LiveDrive is a completely new type of direct-drive motor which can provide robots with more power without using as much electricity, lubrication or space – significant savings in each of those areas and perhaps others. Direct-drive motors do not use gearboxes, but to date, their limited torque means that they have only been suitable for a limited range of applications.

In overly simplistic terms, the LiveDrive is to robots what engines are to cars – it enables machines to move. And critically, it has far greater torque, according to its makers; and can generate this without the need for traditional gears, which have teeth that require lubrication, make a lot of noise, and wear out eventually. LiveDrive uses a patented combination and composition of magnets to achieve what traditional drives and motors achieve by using gears and other mechanisms.

New gearbox range from Harmonic Drive aimed at “growing demand for compactness” and collaborative robotics 

High precision gearing specialist, Harmonic Drive UK, has launched CSF-2UP, a new gearbox range designed for medical technology, robotics and measuring-instrument applications.

Expected to be worth $7.85 billion by 2020, according to MarketsandMarkets, the smart and collaborative robotics sector is particularly dependent on compact and ultra lightweight gears.

The CSF-2UP gearboxes form part of the CSF Series, a range characterised by its very short length and low weight. The new gearbox range is available in three sizes, with gear ratios of 30, 50 and 100 at a repeatable peak torque from 1.8 to 28 Nm.  [Read more…] about Harmonic Drive launches new gearbox to ‘usher in a new age of robotics’
