Title:
ANTI-ROTATION DEVICE FOR ACTUATORS
Document Type and Number:
WIPO Patent Application WO/2015/091887
Kind Code:
A3
Abstract:
An anti-rotation device prevents relative rotation between first and second members (1, 2), one member being telescopingly disposed about the other and at least one member being linearly displaceable along a central axis. First and second guide surfaces (12, 14) are provided on the first member and extend generally parallel with each other and the central axis. First and second rollers (16, 18) are connected with the second member and are each rotatable about an adjustably fixed axis on the second member. The first roller is rollable along the first guide surface to prevent angular displacement between the two members when the displaceable member moves in a first direction and the second roller is rollable along the second guide surface to prevent angular displacement between the two members when the displaceable member moves in an opposing direction. The contact between the rollers (16, 18) and guide surfaces (12, 14) provide a radial degree of freedom to the anti-rotation device.
