Abstract
A torque transmitting apparatus which includes a tubular drive shaft defining a deaeration chamber integral with the interior of the shaft. Aerated liquid is ducted into one axial end of the deaeration chamber and separated air and residual liquid are ducted from the opposite end of the chamber, generally near the center thereof. Relative rapid rotation of the drive shaft causes radial acceleration of the liquid to effect separation of the more dense liquid from the air under the influence of centrifugal force. The deaerated liquid is ported from the outer periphery of the chamber during rotation of the drive shaft.
Claims13
In a torque transmitting apparatus, deaerating means comprising elongated drive shaft means for transmitting power to a machine, gearbox or the like from an appropriate power source, at least a portion of said drive shaft means comprising a torque tube with a tubular wall defining a deaeration chamber directly within the drive shaft means remote from the machine, means for ducting aerated liquid into the deaeraton chamber whereby relatively rapidly rotation of the drive shaft means causes radial acceleration of the liquid to effect radially outward separation of the liquid from the air under the influence of centrifugal force, means located near an outer periphery of the chamber for ducting deaerated liquid herefrom, and means located inwardly of the outer periphery of the chamber for ducting separated air from the chamber.
A deaerating system in a torque transmitting apparatus, comprising:
- elongated drive shaft means having at least a portion thereof defining a torque tube for transmitting power to a machine, gearbox or the like from an appropriate power source;
- annular wall means projecting radially inwardly at axially spaced locations within the torque tube portion of the drive shaft means to define an integral, internal deaeration chamber directly within the drive shaft means remote from the machine;
- opposed port means located generally centrally of said axially spaced wall means defining means for ducting aerated liquid into the chamber at one axial end thereof and means for ducting separated air from the chamber at the oppsote axial end thereof;
- port means in outer walls of the torque tube portion of the drive shaft means between said axially spaced wall means for ducting deaerated liqid from the chamber;
- and
- conduit means extending axially through the drive shaft means in communication with said port means for delivering aerated liquid to the dearation chamber,
- whereby relatively rapid roation of the drive shaft means causes radial acceleration of the liquid in the deaeration chamber to effect radially outward separation of the liquid from the air under the influence of centrifugal force.
In a torque transmitting apparatus, deaerating means comprising drive shaft means at least a portion of which comprises a torque tube having tubular walls defining a deaeration chamber therewithin, said portion of the drive shaft means including a disconnect mechanism for separating said portion from the remainder of the drive shaft means, means for ducting aerated liquid into the deaeration chamber whereby relatively rapid rotation of the drive shaft means causes radial acceleration of the liquid to effect radially outward separation of the liquid from the air under the influence of centrifugal force, means located near an outer periphery of the chamber for ducting deaerated liquid therefrom, and means located inwardly of the periphery of the chamber for ducting separated air from the chamber.
A deaerating system in a torque transmitting, apparatus, comprising:
- drive shaft means having at least a portion thereof defining a torque tube;
- a disconnect mechanism for separating said portion of the drive shaft means from the remainder of the drive shaft means;
- annular wall means projecting radially inwardly at axially spaced locations within the torque tube portion of the drive shaft means to define an integral, internal deaeration chamber;
- opposed port means located generally centrally of said axially spaced wall means defining means for ducting aerated liquid into the chamber at one axial end thereof and means for ducting separated air from the chamber at the opposte axial end thereof;
- port means in outer walls of the torque tube portion of the drive shaft means between said axially spaced wall means for ducting deaerated liquid from the chamber;
- and
- conduit means extending axially through the drive shaft means in communication with said port means for delivering aerated liquid to the deaeration chamber,
- whereby relatively rapid rotation of the drive shaft means causes radial acceleration of the liquid in the deaeration chamber to effect radially outward separation of the liquid from the air under the influence of centrifugal force.
A deaerating torque tube, comprising means defining a deaeration chamber within a portion of the torque tube, a disconnect mechanism in said portion of the torque tube for separating said portion from the remainder of the torque tube, means for ducting aerated liquid to the deaeration chamber whereby relatively rapid rotation of the torque tube causes radial acceleration of the liquid to effect radial separation of the liquid from the air under the influence of centrifugal force, means located near an outer periphery of the chamber for ducting deaerated liquid therefrom, and means located inwardly of the periphery of the chamber for ducting separated air from the chamber.
