Abstract
In an adjustable-length shaft (1) for transmitting torques comprising a circular inner shaft component (2) that is mounted coaxially through a linear ball bearing for sliding telescopically in axial direction in a hollow outer shaft component (3), the inner shaft component (29 is mounted by two spaced-apart pre-stressed linear ball bearings (4) that are arranged on opposite end sections (6) of the inner shaft component (2) and are received in a reception bore (19) of the outer shaft component (3), a transmission of torque being achieved by a positive engagement of the inner and the outer shaft components (2, 3).
Claims8
An adjustable-length shaft for transmitting torques,
- said shaft comprising an inner shaft component of circular cross-section that is mounted coaxially through a linear ball bearing for sliding telescopically in axial direction in a hollow outer shaft component,
- wherein the inner shaft component is mounted by two spaced-apart pre-stressed linear ball bearings that are arranged on opposite end sections of the inner shaft component and are received in a reception bore of the outer shaft component,
- a transmission of torque being achieved by a positive engagement of the inner and the outer shaft components.
