Description
Universal couplings are a type of couplings that allow large
angular displacements between two shafts. They are suitable for
connection between two shafts with large angular displacements.
Generally, the maximum shaft angle between two shafts can reach 35
° ~ 45 °. Moreover, the angle between the two axes can be changed
at any time during the running process.
A universal joint, (universal coupling, U-joint, Cardan joint,
Hardy-Spicer joint, or Hooke's joint) is a joint or coupling in a
rigid rod that allows the rod to 'bend' in any direction, and is
commonly used in shafts that transmit rotary motion. It consists of
a pair of hinges located close together, oriented at 90° to each
other, connected by a cross shaft. The universal joint is not a
constant velocity joint.
No machine element other than a cardan shaft allows power
transmission of torque between specially offset driving and driven
shafts whose position can be changed during operation.
Spatial angular motion and changes of axial length are ensured by
advanced constructional elements.
Thus, cardan shafts have become an indispensable transmission
component in automotive engineering and industry.
Advantages of universal couplings
- Its structure has large angular compensation ability, compact
structure and high transmission efficiency
- multifunctional application
- excellent efficiency
- high reliability
- low maintenance
- easy use
Application of universal coupling
Widely used in automotive industry, agricultural machinery,
industrial machinery and other sports machinery industries.
