Abstract
Abstract A power-consuming rotary appliance is supported and driven by elements involved in the speed changes of the power unit. The apparatus is applicable for either horizontal or vertical axis of rotation of the appliance by slight change to sealing details and with further modification is adaptable to immersion in a body of water. The speed changer comprises at least one planetary gear train and particular design assures proper conditioning and circulation of lube oil in contention with environmental conditions. The use of this apparatus to serve as a winch is stressed as one application.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
308 words
A close-coupled power-driven speed-reducing unit integral with a winch utilizing rotary power, the improvement comprising: a. a planetary gear transmission having at least one train with each train defined as having elements in combination (of a sun gear, planet pinion cage assembly and an internal ring gear) contributing a speed change as a factor of that speed established by said reducer; b. a concentric shroud enclosing at least a portion of said transmission and contributing an extension to the inner chamber of said unit to define an interior oil reservoir accommodates an externally mounted drum; c. said one train having the sun gear as the driving element, the driven element comprising the intErnal ring gear and said shroud intercoupled, and the cage fixedly secured to said unit to support at least one planet pinion rotatable about its static center; d. a cantilever beam extension of said cage provides the journal support of said shroud; e. a lubricating oil system in part activated by a gear pump comprising elements of said one train and operable in either direction of rotation of said unit; f. said inner chamber having a sole means of entry of detrimental matter (defined by an area established between said fixed cage and said driven element) is isolated from external environment by a sealing means (establishing a barrier) across said area against said matter; g. said unit is adapted to immersion in a body of water having said isolated interior filled with a pressurized gas above said reservoir in communication with a supply of gas monitored in balance with environmental conditions external of said seal; h. A spooling means for controlled feed of cable to the drum of said winch; and i. A liquid spray cleaning means disposed annularly around said cable and positioned to effect cable cleaning just prior to cable winding on said drum.

Claim 3
Dependent Claim
58 words
In a power-driven winch unit according to claim 1, said gear pump comprises a gear housing for a portion of said sun gear and for a portion of at least one said planet pinion gear with a check valve means on each side of the mesh of said housed gears to direct pressurized oil from said gear housing.
Claim 4
Dependent Claim
34 words

Claim 5
Dependent Claim
92 words
In a power-driven winch unit according to claim 1, a cup is fixedly secured to said unit to establish a compartment external to said shroud to provide: a. an upper gaseous volume surrounding at least the externally exposed said seal and regulated with said supply; b. a lower liquid volume in communication with the said body of water through a regulated port controlled by a liquid level monitoring means; and c. an intermediate liquid piston disposed between said volumes as a baffle against contamination of said gas volume by said liquid volume.
Claim 6
Dependent Claim
94 words
In a power-driven winch unit according to claim 3, said auxiliary gear pump comprises: a. a rotating gear housing secured to said shroud to accommodate a pair of meshing gears; b. first gear of said pair of gears nonrotatably secured to said cage extension in communication with said reservoir; c. second gear of said pair of gears rotatably mounted to said rotating gear housing to revolve around said first gear; and d. a check valve means disposed on each side of the mesh of said housed gears to direct pressurized oil from said housing.
Claim 7
Dependent Claim
