The Merrill Wheel-Balancing System was the world's first electronic dynamic wheel-balancing system. It was invented in 1945 by Marcellus Merrill at the Merrill Engineering Laboratories, 2390 South Tejon Street, Englewood, Colorado , and is now recorded on the list of IEEE Milestones in electronic engineering [ 1 ] and as an American Society of ...
The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of rotation
Balance weights are then fitted to the outer and inner flanges of the wheel. [2] Although dynamic balance is theoretically better than static balance, because both dynamic and static imbalances can be measured and corrected, its effectiveness is disputed because of the flexible nature of the rubber.
A balancing machine is a measuring tool used for balancing rotating machine parts such as rotors for electric motors, fans, turbines, disc brakes, disc drives, propellers and pumps. The machine usually consists of two rigid pedestals, with suspension and bearings on top supporting a mounting platform.
Two-plane, or dynamic, balancing is necessary if the out-of-balance couple at speed needs to be balanced. The second plane used is in the opposite wheel. Two-plane, or dynamic, balancing of a locomotive wheel set is known as cross-balancing. [11] Cross-balancing was not recommended by the American Railway Association until 1931.
Transaction banking can be defined as the set of instruments and services that a bank offers to trading partners to financially support their reciprocal exchanges of goods (e.g., trade), monetary flows (e.g., cash), or commercial papers (e.g., exchanges). Transaction banking allows banks to maintain close relationships with their corporate ...
Bank licensing, which sets certain requirements for starting a new bank, is closely connected with supervision and usually performed by the same public authority. Licensing provides the licence holders the right to own and to operate a bank. The licensing process is specific to the regulatory environment of the jurisdiction where the bank is ...
In physics, a mass balance, also called a material balance, is an application of conservation of mass [1] to the analysis of physical systems.By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
