A drive includes a transmission driven by an electric motor. A drive shaft of the transmission has multiple eccentric regions with differing widths in the axial direction, in which the high points thereof are offset relative to one another in the circumferential direction. The respective eccentric region is radially surrounded by a respective cam disk region, e.g., of a housing part of the transmission. Respective rollers are accommodated in respective recesses of a cage and arranged with a radial degree of freedom. The cage is rotationally fixed to the output shaft of the transmission, and the output shaft along with the cage is rotatably mounted both relative to the cam disk regions and relative to the drive shaft. During operation, the respective rollers are made to roll and/or slide on the respective cam disk region by the respective eccentric region. The eccentric regions are arranged behind one another in the axial direction such that the dynamic imbalance is minimized and/or eliminated.

In an assembly for connecting an adapter shaft to a shaft in a force-fitting manner using a clamping ring, the clamping ring is mounted on the adapter shaft, the shaft is inserted into the adapter shaft, the clamping ring has a radially continuous threaded bore into which a screw part is screwed, in particular a threaded pin, which exerts pressure on the adapter shaft, at least one insertion ring is inserted in an annular groove introduced into the clamping ring, in particular in an annular groove introduced into the inner wall, i.e. in particular the hollow side of the clamping ring, and/or is at least partially accommodated therein, and the insertion ring, or each insertion ring, has a nose region that projects radially inward and which projects at least partially into a slot of the adapter shaft.

Assembly for connecting an adapter shaft to a shaft in a force-fitting manner using a clamping ring

In an assembly for connecting an adapter shaft to a shaft in a force-fitting manner using a clamping ring, the clamping ring is mounted on the adapter shaft, the shaft is inserted into the adapter shaft, the clamping ring has a radially uninterrupted threaded bore, into which a screw part is screwed, in particular a threaded pin, which exerts pressure on the adapter shaft. A cylinder bolt is accommodated in a first, in particular radially directed, recess of the clamping ring, which projects radially inward into a second, in particular radially directed, recess introduced into the adapter shaft, in particular projects into it, especially in order to form a protection against loss and an anti-rotation protection acting in the axial direction and in the circumferential direction.

In an assembly for connecting an adapter shaft to a shaft in a force-fitting manner using a clamping ring, the clamping ring is mounted on the adapter shaft, the shaft is inserted into the adapter shaft, the clamping ring has a first radially uninterrupted threaded bore into which a first screw part is screwed, in particular a first threaded pin, which exerts pressure on the adapter shaft, the clamping ring has a second radially uninterrupted threaded bore into which a second screw part is screwed, in particular a second threaded pin, and the second screw part projects at least partially into a recess of the adapter shaft and in particular exerts pressure on the adapter shaft.

A coupling includes a shaft at least partially inserted into a hollow shaft and a ring part, in particular of a clamping ring, slipped onto the hollow shaft. The ring part is axially restricted by a collar provided on the shaft, in particular a radially projecting collar, and/or the ring part is resting against a collar, or the collar, of the shaft, in particular against a collar provided on the shaft, in particular a radially projecting collar. The hollow shaft has slots, in particular axial slots, which are set apart from the collar. The ring part has a chamfer, in particular on its inner side and/or at its ring opening and/or in particular in its axial end region facing the collar, so that the inner diameter of the ring part in the axial region covered by the chamfer is greater than the inner diameter in the particular axial region in which the ring part is in contact with the hollow shaft. The ring part has a radially uninterrupted threaded bore into which a screw part, in particular a set screw and/or a threaded pin, is screwed, which exerts pressure on the hollow shaft.
