LOADING DEVICE Russian patent published in 1996 - IPC

FIELD: mechanical engineering, test equipment, for building-up of load in test bench power circuits. SUBSTANCE: the loading device has a cover, cylindrical casing accommodating a wave gearing with an internal arrangement of the strain wave generator, having an axial hole. The wave gearing rigid wheel is fastened to the casing. The reduction gear is mechanically connected to a drive positioned eccentrically to the axis of the wave gearing, and its output gear-wheel is coupled with the wave generator. The screw-nut helical gearing, whose nut is installed for axial motion and the screw is coupled with the wave gearing flexible wheel, is positioned in the axial hole of the wave generator. One of the attachment members connected to the object being loaded is connected to the casing, and the other is connected to the nut. The loading device is furnished with a composite cylinder with internal flanges, the external flanges are made on the screw end, and the thrust bearing represents a multi-row plain bearing formed by the flanges of the screw and cylinder. EFFECT: improved design. 1 dwg
