Abstract

See full text

A device for lubricating a rotatable member such as a hollow shaft on which another member is axially displaceable, has a lubricant container received in the hollow shaft and in which a piston is displaceable by a gas generated by a gas-generating cell or by a motor-driven spindle. The electrical circuit includes a centrifugal-force sensor received in the container and having switches connected in that circuit so that when a certain speed of rotation is reached, the lubricant is dispensed and the circuit is de-energized upon standstill.
