RAILWAY CAR GEARING OF PARALLEL CARDAN DRIVE FORMAT Russian patent published in 2018 - IPC F16H55/08 F16H1/08 B61C9/38 

FIELD: machine building.

SUBSTANCE: invention relates to gearing. Gearing of a railway vehicle with a system of parallel propeller drive has a helical gearing and a helical gearing which together constitute a pair. Gears and the gear wheel have the following gear characteristics, respectively: module 4-8, pressure angle 20°-30° and helix angle 15°-30°, barrel-shaped on the tooth surface in the direction of the tooth gear line. Surface of the tooth has the form of a sinusoidal curve with a vertex located in the central region in the width direction of the gear ring of the gear, wherein the sinusoidal curve is expressed by a single sinusoidal function and extends over the entire width in the width direction of the gear wig of the helical gear.

EFFECT: reduced production costs, as well as reduced vibration and noise during the operation of the gearing.
