Victaulic is a developer and manufacturer of mechanical pipe joining systems, and the originator of the grooved pipe couplings joining system. [1] The firm is a global company with 15 major manufacturing facilities, 28 branches, and over 3600 employees worldwide.
A disc coupling is a high performance motion control coupling designed to be the torque transmitting element (by connecting two shafts together) while accommodating for shaft misalignment. It is designed to be flexible, while remaining torsionally strong under high torque loads. Typically, disc couplings can handle speeds up to 10,000 r/min.
The first mass-produced viscous couplings for a permanent 4WD off-road-capable vehicle were in the AMC Eagle, which was produced from 1980 to 1988 model years. [2] The AMC Eagle's single-speed model 119 New Process central differential used a viscous coupling filled with a liquid silicone-based material. [3]
The fitting is known as a reducing coupling, reducer, or adapter if their sizes differ. There are two types of collars: "regular" and "slip". A regular coupling has a small ridge or stops internally to prevent the over-insertion of a pipe and, thus, under-insertion of the other pipe segment (which would result in an unreliable connection).
A fluid coupling cannot develop output torque when the input and output angular velocities are identical. [7] Hence, a fluid coupling cannot achieve 100 percent power transmission efficiency. Due to slippage that will occur in any fluid coupling under load, some power will always be lost in fluid friction and turbulence, and dissipated as heat.
ZF torque converter cut-away A cut-away model of a torque converter. A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load.
Torque charts are available to specify the required torque for a given fastener based on its property class (fineness of manufacture and fit) and grade (tensile strength). Spring Analogy for a Bolted Joint. When a fastener is tightened, a tension preload is develops in the bolt, while an equal compressive preload forms in the clamped parts.
An animation of a Hobson joint. A Hobson's joint or Hobson's coupling is a type of right-angle constant-velocity joint; rods bent 90° are able to transmit torque around a corner because they are all free to turn in their mounting holes in both legs of the coupling.
