WebNov 1, 1986 · Curvic Couplings were first introduced in 1942 to meet the need for permanent couplings and releasing couplings (clutches), requiring extreme accuracy … 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).
