  2. Coupling - Wikipedia

    en.wikipedia.org/wiki/Coupling

    In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. [1] Couplings do not normally allow disconnection of shafts during operation, however there are torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and ...

  3. Couple (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Couple_(mechanics)

    Couples are very important in engineering and the physical sciences. A few examples are: The forces exerted by one's hand on a screw-driver; The forces exerted by the tip of a screwdriver on the head of a screw; Drag forces acting on a spinning propeller; Forces on an electric dipole in a uniform electric field

  4. Jaw coupling - Wikipedia

    en.wikipedia.org/wiki/Jaw_coupling

    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.

  5. Linkage (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Linkage_(mechanical)

    Mechanical linkages are usually designed to transform a given input force and movement into a desired output force and movement. The ratio of the output force to the input force is known as the mechanical advantage of the linkage, while the ratio of the input speed to the output speed is known as the speed ratio. The speed ratio and mechanical ...

  6. Kinematic coupling - Wikipedia

    en.wikipedia.org/wiki/Kinematic_coupling

    The reproducibility and the precision of a kinematic coupling come from the idea of exact constraint design. The principle of exact constraint design is that the number of points of constraint should be equal to the number of degrees of freedom to be constrained. [1] In a mechanical system there are six potential degrees of freedom.

  7. Universal joint - Wikipedia

    en.wikipedia.org/wiki/Universal_joint

    A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It 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.

  8. Fluid coupling - Wikipedia

    en.wikipedia.org/wiki/Fluid_coupling

    A fluid coupling or hydraulic coupling is a hydrodynamic or 'hydrokinetic' device used to transmit rotating mechanical power. [1] It has been used in automobile transmissions as an alternative to a mechanical clutch .

  9. Constant-velocity joint - Wikipedia

    en.wikipedia.org/wiki/Constant-velocity_joint

    A Rzeppa-type CV joint. A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
