The balance lever coupling, also central buffer coupling with two screw coupling, is a coupler commonly used on narrow gauge railroads with tight curves. By swapping the pulling and pushing devices, the standard screw coupling used on standard gauge railroads became a center buffer coupling with one screw coupling on each side of the buffer.
At its annual convention at Dallas, TX, the NFPA formally adopted a standard with 2 + 1 ⁄ 2-inch hose with 7.5 threads per inch as the primary standard, with additional sizes of 3 and 3.5 inches (each with 6 threads per inch) and a 4.5 inch coupling with 4 threads per inch, with the fire hydrant standard specifying one 4.5 inch port and two 2 ...
Centrifugal clutches were used in railway locomotives before 1858, [1] and referred to (in relation to electric motors) in a patent of 1899. [2] A patent was issued in the United States for an automotive centrifugal clutch (on an electric vehicle) in 1898. [3] There is a design for a toy 'automatic clutch' in Meccano Magazine of June 1934. [4]
In mechanical engineering, a jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control (servo) applications. It is designed to transmit torque (by connecting two shafts ) while damping system vibrations and accommodating misalignment, which protects other components from damage.
The selector is typically symmetric: it slides between two gears and has a synchromesh and teeth on each side in order to lock either gear to the shaft. Unlike some other types of clutches (such as the foot-operated clutch of a manual-transmission car), a dog clutch provides non-slip coupling and is not suited to intentional slipping.
Victaulic specializes in the development of couplings, valves, and fitting technologies for a variety of industries. Its main products are: Grooved couplings used to join mechanical pipes together. [3] The company produces a variety of these grooved couplings along with other technologies since it was founded. [4]
The clutches and bands are operated by hydraulic pressure. In this case, forward means closest to the engine. When applied, a clutch connects a rotational component to the engine, causing the component to turn, and a band holds the component, preventing it from turning. The forward clutch controls power to the primary sun gear.
There are also mechanical designs for torque converters, many of which are similar to mechanical continuously variable transmissions or capable of acting as such as well. . They include the pendulum-based Constantinesco torque converter, the Lambert friction gearing disk drive transmission and the Variomatic with expanding pulleys and a belt dri
