F16D 3/202

one coupling part having radially projecting pins, e.g. tripod joints

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

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 > one coupling part entering a sleeve of the other coupling part and connected thereto by sliding or rolling members > one coupling part having radially projecting pins, e.g. tripod joints

CPC:

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 > one coupling part entering a sleeve of the other coupling part and connected thereto by sliding or rolling members (F16D3/18, F16D3/24 take precedence) > one coupling part having radially projecting pins, e.g. tripod joints

Of 4 combined children, 2 exist in both systems.

2 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1990.
