COUPLING HALF FOR ROTATIONALLY FIXED CONNECTING OF SHAFT Russian patent published in 2018 - IPC F16D1/02 F16D1/33 F16D3/02 B61C9/44 

FIELD: rail vehicles.

SUBSTANCE: invention relates to transmissions for rail vehicles. Radially-axially movable coupling consists of two parts. Parts are connected torsionally-elastically and have one coupling half for shaft connection. Coupling comprises flange (1) having end toothed ring (3). Ring (3) is made in the form of a flat ring with a plurality of teeth (5) with a trapezoidal cross-section and flat lateral sides (5.1) of the teeth, said plurality of teeth positioned adjacent to each other and separated by corresponding inter-tooth space (6). Between each two lateral sides (5.1) of the teeth there is a tooth flat head (5.2) positioned on the axial end of the coupling half. In one coupling half, in its axial direction, through exactly each tooth head (5.2), a flanged threaded connection passes or an opening is made for the flange threaded connection. In the other coupling half, in its axial direction, through exactly each inter-tooth space (6), a flanged threaded connection passes or an opening is made for the flange threaded connection.

EFFECT: increase in the maximum permissible load.
