A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle) without involving any intermediate couplings such as a gear train or a belt. [1] [2] [3] [4]
The film adaptation of The Hunt for Red October popularized the magnetohydrodynamic drive as a "caterpillar drive" for submarines, a nearly undetectable "silent drive" intended to achieve stealth in submarine warfare. In reality, the current traveling through the water would create gases and noise, and the magnetic fields would induce a ...
By 1922, Link-Belt expanded into this crawler-mounted crane-shovel excavator market, complementing its locomotive cranes and material handling equipment. As the rail-based market shrank, Link-Belt's crawler-mounted line continued to grow. By the late 1930s, Link-Belt offered excavators ranging from a 3/4-yd to a 2-1/5-yd capacity.
[2] [3] Some aquariums use magnetic drive pumps, which have a magnetic coupling between the motor on the dry side of an aquarium wall and the propeller or impeller in the water on the other side of the wall. [4] This coupling features two face-to-face magnetized disks: the driving magnet on the dry side, and the driven magnet on the underwater ...
Link-Belt or Link Belt may refer to: A linked-belt drive, a type of chain drive; Link-Belt Cranes, a subsidiary of Sumitomo Group. LBX Link-Belt Excavators, ...
A magnetic bearing. A magnetic bearing is a type of bearing that supports a load using magnetic levitation.Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical w
Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...
[4] [5] A popular example of a magnet motor, although without rotating axis, was put forward by John Wilkins in 1670: A ramp with a magnet at the top, which pulled a metal ball up the ramp. Near the magnet was a small hole that was supposed to allow the ball to drop under the ramp and return to the bottom, where a flap allowed it to return to ...
