Abstract
An articulated spindle as used for example in a rolling mill drive has a shank the ends of which are connected to sleeves through gear-type couplings. Liquid is continually passed through each gear-type coupling for cooling and lubrication. The liquid is supplied under pressure through the shank to the couplings, passes through the couplings, and is withdrawn under suction through return conduits which rotate with the shank. The liquid is supplied by a delivery pump through a rotating joint to the shank and is withdrawn from the return conduits through the rotating joint by a suction pump.
Claims10
An articulated coupling comprising:
- (a) a rotatable shank;
- (b) a sleeve surrounding one end of said shank;
- (c) drive coupling means between said end of said shank and said sleeve permitting limited variation in the inclination of the axis of said shank relative to the axis of said sleeve;
- (d) a supply system for supplying liquid under pressure to and through said shank and to and through said drive coupling means;
- (e) a liquid return conduit leading from said drive coupling means through said shank to withdraw liquid delivered from said means, said return conduit constructed and arranged to rotate with said shank;
- and
- (f) means for withdrawing liquid through said conduit under suction.
An articulated spindle comprising:
- (a) a rotatable shank;
- (b) a first sleeve and a second sleeve respectively surrounding a first end and a second end of said shank;
- (c) first drive coupling means between said first shank end and said first sleeve;
- (d) second drive coupling means between said second shank and said second sleeve;
- (e) each said drive coupling means permitting limited variation of the inclination of the axis of said shank and the axis of the respective coupling;
- (f) a supply system for supplying liquid under pressure to and through said shank and to and through each said drive coupling means;
- (g) a liquid return conduit for each said drive coupling means passing through said shank to withdraw liquid thereform, each said return conduit constructed and arranged to rotate with said shank;
- and
- ((h) means for withdrawing liquid through said conduits under suction.
