Abstract
Abstract An angle drive in which two angularly related stub shafts are interconnected by a pair of meshed gears, each of which is carried by a respective shaft, said gears being disposed in a housing with the free ends of the respective shafts extending therefrom, the housing having an opening therein through which both shafts and associated gears may be inserted, sleeves being provided for supporting the respective shafts which are threaded in respective bores in the housing for adjustment of such shafts and the gears thereon, whereby the respective gears may be larger than such bores and, if desired, integrally formed with such shafts, means being provided for locking the sleeve members in adjusted positions and for assuring lubrication of the drive.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
191 words
An angle drive comprising a pair of stub shafts, a housing having a pair of bores therein, disposed on respective axes extending in intersecting directions, each bore being adapted to receive one of said shafts, each of the latter being provided with a gear rigidly connected therewith, shaft and gear to form a uniting structure, said gears being constructed to operatively mesh for the transmission of rotary movement of one shaft to the other, the gear of at least one of said gear structures being greater in overall diameter than the associated bore, said housing having an opening therein of a size and location to permit insertion of each unitary shaft and gear structure there through into operative position with respect to the associated bore, means for operatively closing said opening, a respective sleeve member for each shaft, disposed in the associated bore with the cooperable shaft journaled in such sleeve member, each of the latter being constructed to support the gear of the associated shaft and gear structure in meshed relation with respect to the other gear and means for retaining said sleeves in operative positions, in their respective bores.
Claim 2
Dependent Claim
191 words
An angle drive comprising a pair of stub shafts, a housing having a pair of bores therein, disposed on respective axes extending in intersecting directions, each bore being adapted to receive one of said shafts, each of the latter being provided with a gear rigidly connected therewith, shaft and gear to form a uniting structure, said gears being constructed to operatively mesh for the transmission of rotary movement of one shaft to the other, the gear of at least one of said gear structures being greater in overall diameter than the associated bore, said housing having an opening therein of a size and location to permit insertion of each unitary shaft and gear structure there through into operative position with respect to the associated bore, means for operatively closing said opening, a respective sleeve member for each shaft, disposed in the associated bore with the cooperable shaft journaled in such sleeve member, each of the latter being constructed to support the gear of the associated shaft and gear structure in meshed relation with respect to the other gear and means for retaining said sleeves in operative positions, in their respective bores.
Claim 3
Dependent Claim
36 words

Claim 5
Dependent Claim
17 words
A drive according to claim 1, wherein the shaft axes intersect and extend through said housing openings,
Claim 6
Dependent Claim
29 words
A drive according to claim 1, wherein both gears having overall diameters greater than the diameter of said bores, and are inserted into the housing through the opening therein.
Claim 7
Dependent Claim
21 words
A drive according to claim 1, wherein each of said sleeves is provided with anti-friction bearings for supporting the respective shaft.
Claim 8
Dependent Claim
23 words

Claim 9
Dependent Claim
26 words
A drive according to claim 1, wherein said sleeve-retaining means comprises internal threads in the respective bores, cooperably engageable with external threads on the associated sleeve.
Claim 10
Dependent Claim
43 words
A drive according to claim 2, wherein said sleeves each are of a length to project from the associated bore, and a jam-nut threaded on the projecting portion of the associated slEeve for locking the latter in adjusted position relative to the housing.
Claim 11
Dependent Claim
41 words
A drive according to claim 9, wherein said jam-nut is in the form of a hollow cap member through which the associated shaft extends, and means on each cap member engageable with the associated shaft to provide an oil seal therebetween.
Claim 12
Dependent Claim
47 words
A drive according to claim 10, wherein said housing is adapted, in operative position, to dispose one of said cap members at the uppermost portion thereof, such cap member having an oil filler opening and an air relief opening therein, and closure means for such respective openings.
Claim 13
Dependent Claim
79 words
A drive according to claim 9, wherein each of said bores is provided with a flared mouth, each sleeve having an annular circumferential groove therein, of an axial length to be disposed opposite such flared mouth throughout the adjustment range of the sleeve, and an annular resilient sealing ring, partially disposed in said flared mouth and said groove, adapted to be compressed into sealing relation with said sleeve and housing by engagement of said jam-nut with said sealing ring.
Claim 14
Dependent Claim
36 words
