Curvic coupling enveloped half pitches
WebIn a real rotor-spline coupling system, all splines meshing tightly by transmitting large torque cause a deformation of each spline. At the same time, for coupling nodes vibrating with the system, there is relative displacement between splines in two half-couplings, which cause another deforma-tion of each spline; both the deformations generate ...

WebFeb 3, 2024 · A parametric study is performed which varies tooth contact pattern, tooth number, pressure angle, half pitch number, and tooth rigidity to evaluate their effects on vibration and stress. The proposed approach is also applied to an industrial rotor to illustrate the effect of the new Curvic coupling model on critical speeds. Web[0002] Curvic couplings for use in the assembly of rotat ing element components Were developed to meet the need for permanent coupling mechanisms requiring extreme accuracy, maximum load capacity, and relatively economi cal rates of production. The curvic design provides an
WebHirth joint (disassembled) between the semi-axles of a Campagnolo Ultra-Torque crankset. 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.
WebFeb 3, 2024 · The curvature of the Curvic coupling teeth increases as the half pitch number decreases, which results in a greater contact surface area as shown in Fig. 5. Since more curved tooth has more bearing length, the average surface stress is lowered. Fig. 29 shows that the natural frequencies are unaffected by the half pitch number. five purple kitesWebNov 1, 1986 · Curvic Couplings were first introduced in 1942 to meet the need for permanent couplings and releasing couplings (clutches), requiring extreme accuracy and maximum load carrying capacity, together with a fast rate of production.
