REMOVABLE HUB FOR ASSEMBLY OF ROTATING ELEMENT ON DRIVEN SHAFT Russian patent published in 2010 - IPC F16D1/09 

FIELD: machine building.

SUBSTANCE: removable hub consists of conic bushing, of driven element enveloping conic bushing, of grip nut, of retaining ring, of clamping nut and of coupling screws. The conic bushing has degree of taper 1: 10 and has a radial slit. Internal diametre of the conic bushing corresponds to diametre of the driven shaft, while its external diametre corresponds to a conic orifice of the driven element also made with degree of taper 1: 10. The driven element is clamped on the conic bushing. Four reinforced sectors at angle of 90° to each other are arranged on an external part of the conic bushing. The conic bushing and the driven element are tightened by means of the coupling screws running through corresponding threaded orifices on a back washer-like side of the conic bushing and on the driven element. Also the coupling screws are arranged at 90° to each other. The conic bushing is tightened with the grip nut and is fixed by means of the retaining ring and the clamping nut. A pulley or a sprocket can be used as a driven element.

EFFECT: simplified design of hub, raised reliability of fixation at dynamic loads.
