The invention relates to a gearwheel arrangement () with a main gearwheel () and a gearwheel () rotatable relative to the latter in circumferential direction (), wherein the main gearwheel () comprises a hub () on which the rotatable gearwheel () is arranged, and with a spring element (), which is arranged between the main gearwheel () and the rotatable gearwheel (), and by means of which the rotatable gearwheel () is pretensioned in circumferential direction () against the main gearwheel (), wherein the main gearwheel () comprises at least one first support element () and the rotatable gearwheel () comprises at least one second support element (), and wherein the spring element () is arranged between the first and the second support element () and thereby spaced apart from the first surface () of the main gearwheel () and from the second surface () of the rotatable gearwheel ().

Gearwheel arrangement

The invention relates to a toothed wheel arrangement () comprising a main toothed wheel () and a toothed wheel () that can be rotated relative thereto in the circumferential direction (), wherein the main toothed wheel () comprises a toothed wheel body () on which a hub () is arranged in a projecting manner in the axial direction so as, firstly, to accommodate a shaft and, secondly, to arrange the rotatable toothed wheel () thereon, for which purpose the rotatable toothed wheel () has a cutout () coaxial to an axially extending center axis of the main toothed wheel (), and wherein the main toothed wheel () is connected to the rotatable toothed wheel () by means of a bayonet fastening (). The bayonet fastening () is formed between the hub () and the rotatable toothed wheel () and/or between the hub () and a spring element () bearing on the rotatable toothed wheel ().

The invention relates to a gear arrangement (), comprising a main gear () and a gear () that can be rotated relative to the main gear in the circumferential direction (), wherein the main gear () or the rotatable gear () has at least one supporting web () that protrudes in the axial direction () and the rotatable gear () or the main gear () has at least one opening (), in which the supporting web () is at least partially accommodated, wherein the opening () has a dimension in the circumferential direction () that is greater than the dimension of the supporting web () in the same direction, and comprising at least one spring element (), which acts in the circumferential direction () of the main gear () and which is arranged on a lateral surface () of the supporting web () or on a lateral surface () of the opening () and at least partially within the opening (). The spring element () is connected to the supporting web () or the lateral surface () of the opening ().

Gear arrangement

The invention relates to a vane pump (), in particular a regulatable oil pump for a lubricating system, with a pump housing () with at least one housing tank () and with a vane rotor () disposed in the housing tank () mounted so that it can be rotated by means of a drive shaft () in the pump housing () constituting an axis of rotation () which provides a mount for vanes () in approximately radially extending fitting slots (). An adjusting ring () is provided enclosing the vane rotor () and circumferentially bounding pump cells () which, by means of a cylindrical internal wall surface (), can be displaced between a concentric position with respect to the vane rotor () and an eccentric position relative thereto, to which pressured is applied by positioning torques caused by the medium pressure and a positioning mechanism () in order to regulate a pressure level.
