Abstract
A shaft system including a shaft having a peripheral groove extending in the circumferential direction, and further including a securing device as well as an interlocking connection by a deformation of the securing device into the groove. The securing device forms a first axial stop for a shaft component. The securing device includes a second axial stop. Also disclosed are an electric machine having the shaft system as well as a process for manufacturing the shaft system.
Claims13
A shaft system, comprising:
- a shaft with a peripheral groove extending in a circumferential direction;
- a shaft component;
- a securing device;
- an interlocking connection formed by a deformation of the securing device into the groove;
- the securing device forms a first axial stop for the shaft component;
- and the securing device includes a second axial stop;
- wherein the peripheral groove includes a first peripheral groove extending in the circumferential direction and a second peripheral groove extending in the circumferential direction, the securing device includes a first securing device and a second securing device, each of which comprises the interlocking connection, the first stop and the second stop, the first securing device has the first interlocking connection to the first groove at a first location on the shaft, and the second securing device has the second interlocking connection to the second groove at a second location of the shaft, wherein the shaft component is arranged adjacent the first axial stop of the first securing device and a further shaft component is arranged between the second axial stop of the first securing device and the second axial stop of the second securing device;
- and
- wherein the shaft component and the further shaft component are on opposite axial sides of the first securing device.

A shaft system, comprising:
- a shaft with a peripheral groove extending in a circumferential direction;
- a shaft component located on the shaft;
- a ring-shaped securing device;
- a radial deformation of the ring-shaped securing device into the groove forming an interlocking connection of the securing device to the shaft;
- the ring-shaped securing device forms a first axial stop for the shaft component;
- and the ring-shaped securing device includes a second axial stop, wherein the peripheral groove includes a first peripheral groove extending in the circumferential direction and a second peripheral groove extending in the circumferential direction, the securing device includes a first securing device and a second securing device, each of which comprises the radial deformation forming the interlocking connection, the first stop and the second stop, the first securing device has the radial deformation forming the first interlocking connection to the first groove at a first location on the shaft, and the second securing device has the radial deformation forming the second interlocking connection to the second groove at a second location of the shaft, wherein the shaft component is arranged between the first axial stop of the first securing device and the first axial stop of the second securing device, and a further shaft component is arranged between the second axial stop of the first securing device and the second axial stop of the second securing device;
- and
- wherein the shaft component and the further shaft component are on opposite axial sides of the first securing device.
