A Hirth joint or Hirth coupling is a type of mechanical connection named after its developer Albert Hirth. It is used to connect two pieces of a shaft together and is characterized by tapered teeth that mesh together on the end faces of each half shaft. See more Hirth joints consist of radial teeth formed by grooves milled or ground into the end face of a cylindrical shaft. The teeth mesh around a ring, as the torque capacity of teeth increases with their diameter. This … See more • Very high loads can be transferred in a small enclosure of only a few parts (two serrated faces and a bolt fixing them together). See more Hirth's joints were first used in aircraft engine crankshafts. A large number of cylinders and often the need for reduction gears and supercharger drives made it impractical to … See more • Rotating spline See more • The manufacturing process is complex, time-consuming and consequently expensive. See more Curvic couplings are similar in concept and appearance to Hirth couplings, except that their teeth are curved instead of straight. Like Hirth couplings, they lock the components together in an unlockable/removable way and provide indexability See more • Elastic Averaging See more WebHirth couplings, also regarded as curvic couplings, are widely used for torque transmission between mating discs in turbine machinery and are not covered by … WebDec 1, 2024 · This article studies the optimization problem of assembly coaxiality of multistage rotors with curvic couplings, and proposes a method for indirectly measuring the positioning and orientation errors between the mating surfaces of a single-stage rotor with curvic couplings. chemistry platform
