F16D 3/16 Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts
Introduced: September 1968
Full Title
Full titles differ between systems:
Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts
Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
4 shared codes have differing titles between IPC and CPC.
