One of the mysteries of the English language finally explained.
A transmission system used in motor vehicles that depends upon friction between moving parts in contact to transmit motion.
- ‘The result is dramatically improved pointing and tracking capability which is far superior to a conventional worm drive and the equal of a more expensive friction drive.’
- ‘There also are known friction drives with constant speed ratio.’
- ‘Noise and the constant need for lubrication are just a few of those problems that our new friction drives have eliminated.’
- ‘As their names imply, friction drives transmit power through the friction that exists between the belt and the pulley while positive drives rely on the engagement of the belt's teeth with grooves on the pulley.’
- ‘Using friction drives in the past required spinning the scope or using a level and making a best estimate of the final drive ratios to enter into the software.’
