Rebar coupler. Mechanical couplers can be advantageous in comparison with conventional methods of lap splicing because of the requirement for less steel for overlapping. It is more effective in the seismic detailing to avoid reinforcement congestion problems. [3] The couplers are also used in pre-cast construction. [4]
A gear coupling is a mechanical device for transmitting torque between two shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle. Each joint consists of a 1:1 gear ratio internal–external gear pair.
The suppliers of these couplers agreed to this voluntarily so semi-automatic couplers were withdrawn from sale in the UK by around October 2008. Safety authorities in other countries have taken a different approach. In Australia the authorities took the view that the problems were caused by designs of quick couplers that did not incorporate a ...
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 SA3 coupler is one of the strongest couplers in the world – maximum tonnage of a train that uses this type of coupler is about 8000 t [31] – but provides only mechanical coupling. [24] Adding automatic electrical and pneumatic connectivity is a complex challenge.
Type F interlocking couplers on upcoming PNR narrow-gauge flatcars. [37] Type H tightlock coupling on most PNR rolling stock starting with the 900 class. Link and pin couplers on the Hawaiian Philippine Company of Negros Island. [38] Older Manila Railroad stock also use link and pin alongside English couplers. Scharfenberg couplers on the MRT ...
The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
A magnetic coupling is a component which transfers torque from one shaft to another using a magnetic field, rather than a physical mechanical connection. They are also known as magnetic drive couplings, magnetic shaft couplings, or magnetic disc couplings. Magnetic coupling
