A worm drive tuning device is called a machine head. Plastic worm drives are often used on small battery-operated electric motors, to provide an output with a lower angular velocity (fewer revolutions per minute) than that of the motor, which operates best at a fairly high speed, in addition to being quieter than a drive with metal gears.

A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward. [1] [2]
Non-circular gear example Another non-circular gear. A non-circular gear (NCG) is a special gear design with special characteristics and purpose. While a regular gear is optimized to transmit torque to another engaged member with minimum noise and wear and with maximum efficiency, a non-circular gear's main objective might be ratio variations, axle displacement oscillations and more.
The diesel-electric transmission of power from the engine to the propeller affords flexibility in distribution of machinery within the vessel at a higher first cost than direct-drive propulsion. It is a preferred solution for vessels that employ pod-mounted propellers for precision positioning [ 21 ] or reducing general vibrations by highly ...
The in-line engine was inherently suitable for shaft drive, and BMW-style bevel gears would have been ideal. However, having inherited some worm-gear machinery from the Lanchester Motor Company, BSA opted to specify worm drive rather than bevel gears. Reputedly this created problems with the shaft drive, as the gears tended to strip under power ...
Elton John's gift may be his song, but that doesn't mean he loves them all.. During an appearance on The Late Show with Stephen Colbert on Tuesday, Dec. 17, the 77-year-old musician spoke about ...
The Z-drive is so named because of the appearance (in cross section) of the mechanical driveshaft or transmission configuration used to connect the mechanically supplied driving energy to the Z-drive azimuth thruster device. This form of power transmission is called a Z-drive because the rotary motion has to make two right angle turns, thus ...
In a worm-drive saw, the blade is driven by a perpendicularly mounted motor using worm gears, which give higher torque. The worm-drive portable circular saw was invented in 1923 by Edmond Michel. In 1924 Michel formed a partnership with Joseph Sullivan, and together they started the Michel Electric Handsaw Company , with the sole purpose of ...
