A minute wheel whose pinion drives the hour wheel. During setting it is driven by the intermediate wheel in the keyless works and it turns both the cannon pinion and the hour wheel, moving the hands. An hour wheel which fits over the shaft of the cannon pinion and whose shaft holds the hour hand. The hour wheel rotates once for every 12 ...
Functioning of the rack and pinion on the Strub system. A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail.
The rack and pinion mechanism is used in rack railways, where the pinion mounted on a locomotive or a railroad car engages a rack usually placed between the rails, and helps to move the train up a steep gradient. It is also used in arbor presses and drill presses, where the pinion is connected to a lever and displaces a vertical rack (the ram).
Each of the powered bogies fitted to the class is equipped with two traction motors, and with Abt rack system pinion wheels. Both members of the class can be marshalled as part of a longer train comprising up to three similar trains, including ABDeh 4/10 2011 class trains.
The two 160 hp three-phase asynchronous motors, rotating at 750 rpm, drive two central toothed wheels via a pair of double reduction gears. The rack system is used for both driving and braking. The locomotives are equipped with two hand brakes, capable of stopping the train: they act on each toothed wheel via grooved drums located on either side.
In many cases, such as remote controlled toys, the pinion is also the drive gear for a reduction in speed, since electric motors operate at higher speed and lower torque than desirable at the wheels. However the reverse is true in watches, where gear trains commence with a high-torque, low-speed spring and terminate in the fast-and-weak escapement.
The cog, or rack and pinion, system that allows the locomotive to climb Mount Washington. Located in the museum. The rack rail design used is one of Marsh's own inventions, using a ladder-like rack with open bar rungs engaged by the teeth of the cog wheel. This system allows snow and debris to fall through the rack, rather than lodging in it. [42]
The Siemens ACS-64, or Amtrak Cities Sprinter, is an electric locomotive designed by Siemens Mobility for use on the Northeast Corridor (NEC) and the Keystone Corridor in the northeastern United States. The design was based on locomotives Siemens created for use in Europe and Asia, but with changes to comply with American standards.
