Damper winding. Bars and rings of the damper (amortisseur) winding of an AC generator (General Electric, early 20th century). Note the gaps in the cage along the quadrature axes. The damper winding (also amortisseur winding[1]) is a squirrel-cage -like winding on the rotor of a typical synchronous electric machine.
W. H. Allen Co. Original York Street, Lambeth Works in 1880. The Company, initially known as W. H. Allen & Co was founded in 1880 by William Henry Allen as a manufacturer of centrifugal pumps and steam engines in York Street, Lambeth, London. [1] [2] Electric light generating machinery followed with the support of Gisbert Kapp.
Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective manner.
A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, [1] long cantilevered signs [2] and cable-stayed bridges. The dumbbell -shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main ...
A dashpot, also known as a damper[citation needed], is a mechanical device that resists motion via viscous friction. [1] The resulting force is proportional to the velocity, but acts in the opposite direction, [2] slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation diagram ...
Shock absorber. Miniature oil-filled Coilover shock components for scale cars. A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
Williamson County Historical Society sign for Allen Manufacturing Company, also known as Dortch Stove Works. Dortch Stove Works is an historic stove manufacturing plant in Franklin, Tennessee. It was built in 1929 by Allen Manufacturing Company, then based in Nashville, Tennessee. During its manufacturing prime, the plant produced stoves and ...
The Geislinger damper utilizes steel leaf springs and engine oil. A related device is the Geislinger damper. [5] This is broadly the same coupling, but both input and output shafts are connected to the same central hub. The massive outer casing is connected to this through similar leaf spring packs, but is free to move torsionally, with damping.
