Abstract
The invention relates to a shaft assembly for a rotating machine, comprising a shaft, a clamping element and a retaining element. The clamping element can be implemented as a circlip for counteracting or limiting axial movement of a shaft attribute. Further, the retaining element has a mainly annular geometry extending in a circumferential direction around the shaft. Also, the retaining element is provided with a locking element located offset from the shaft such that the clamping element is radially locked between the shaft and the locking element.
Claims17
A shaft assembly for a rotating machine, comprising:
- a shaft which is configured to rotate and to transfer torque;
- a clamping element positioned on the shaft for counteracting or limiting movement of a shaft attribute mounted on the shaft in at least one axial direction, the clamping element having a mainly annular geometry extending in a circumferential direction around the shaft, the clamping element further having two circumferential end portions opposing each other, wherein the clamping element is elastically deformable between a relaxed state wherein the two circumferential end portions are located relatively close to each other and a widened state wherein the two circumferential end portions are located relatively remote from each other in the circumferential direction;
- and
- a retaining element positioned on the shaft, the retaining element having a mainly annular geometry extending in the circumferential direction around the shaft, the retaining element further being provided with a locking element located offset from the shaft such that the clamping element is radially locked between the shaft and the locking element.
A retaining element to be positioned on a shaft being configured to rotate and to transfer torque, wherein a clamping element is positioned on the shaft for counteracting or limiting movement of a shaft attribute mounted on the shaft in at least one axial direction, the clamping element having a mainly annular geometry extending in a circumferential direction around the shaft, the clamping element further having two circumferential end portions opposing each other, wherein the clamping element is elastically deformable between a relaxed state wherein the circumferential end portions are located relatively close to each other and a widened state wherein the end portions are located relatively remote from each other in the circumferential direction, the retaining element having a mainly annular geometry extending in the circumferential direction around the shaft, the retaining element further being provided with a locking element located offset from the shaft such that the clamping element is radially locked between the shaft and the locking element.
A method for assembling a shaft assembly, comprising the steps of:
- providing a shaft which is configured to rotate and to transfer torque, the shaft having a shaft attribute mounted thereon,
- shifting a retaining element on the shaft reaching the shaft attribute, the retaining element having a mainly annular geometry extending in a circumferential direction around the shaft, the retaining element further being provided with a locking element located offset from the shaft,
- shifting a clamping element on the shaft for counteracting or limiting movement of the shaft attribute mounted on the shaft in at least one axial direction, the clamping element having a mainly annular geometry extending in the circumferential direction around the shaft, the clamping element further having two circumferential end portions opposing each other, wherein the clamping element is elastically deformable between a relaxed state wherein the two circumferential end portions are located relatively close to each other and a widened state wherein the two circumferential end portions are located relatively remote from each other in the circumferential direction, and
- moving the clamping element towards an axial position on the shaft wherein the clamping element is radially locked between the shaft and the locking element of the retaining element.
