Abstract
Abstract A differential having bevel satellites which are in constant mesh with bevel pinions of output shafts, the outer end faces of said bevel satellites being engaged with the inner surface of a ring member disposed outside (or inside) of a differential casing. This ring member is movable in a plane normal to the rotational axes of the differential casing and is prevented from shifting relative to the differential casing along the rotational axes thereof. The ring member so positioned ensures counter-balancing of the thrust acting upon the satellites and of specific pressures developed in the zone of the engagement between the bevel pinions and satellites.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
A bevel gear differential comprising: a housing; a driving rotatable differential casing accommodated in said housing; a spider having a group of axially disposed axles, said spider being accommodated in said casing to rotate therewith; bevel satellites mounted at the ends of said radially disposed axles; a pair of coaxially and concentrically disposed output shafts journalled in said housing, the inner ends of said output shafts being arranged inside said casing adjacent each other; beVel pinions each mounted on the respective ends of said output shafts and being in constant mesh with said satellites; said differential casing being provided with a ring the inner surface of the ring engaging the outer end faces of said satellites, said ring being movable in a plane normal to the rotational axis of the differential casing and prevented from shifting relative to the differential casing along the rotational axis thereof, whereby the counterbalance of the thrust acting upon the satellites and of specific pressures developed in the zone of engagement between the bevel pinions and satellites is ensured.
Claim 2
Dependent Claim
174 words
A bevel gear differential comprising: a housing; a driving rotatable differential casing accommodated in said housing; a spider having a group of axially disposed axles, said spider being accommodated in said casing to rotate therewith; bevel satellites mounted at the ends of said radially disposed axles; a pair of coaxially and concentrically disposed output shafts journalled in said housing, the inner ends of said output shafts being arranged inside said casing adjacent each other; beVel pinions each mounted on the respective ends of said output shafts and being in constant mesh with said satellites; said differential casing being provided with a ring the inner surface of the ring engaging the outer end faces of said satellites, said ring being movable in a plane normal to the rotational axis of the differential casing and prevented from shifting relative to the differential casing along the rotational axis thereof, whereby the counterbalance of the thrust acting upon the satellites and of specific pressures developed in the zone of engagement between the bevel pinions and satellites is ensured.
Claim 3
Dependent Claim
42 words
A differential according to claim 1, wherein the ring is disposed inside the differential casing, and bearing washers movable along the radially disposed axles are placed between the associated outer end faces of the satellites and said ring to provide engagement therebetween.
Claim 4
Dependent Claim
48 words
A differential according to claim 1, wherein the ring is made flexible and disposed on the outer surface of the differential casing, the engagement of said ring with the outer end faces of the satellites being accomplished through bearing washers and inserts movable along the radially disposed axles.
Claim 5
Dependent Claim
44 words
A differential according to claim 3, wherein a wedge member is placed between the ring and the differential casing, said wedge member being movable in the axial direction and adjusting the working depth of teeth in mesh of the satellites and the bevel pinions.
Claim 6
Dependent Claim
76 words
A differential according to claim 3, wherein each of the inserts comprises a parallelepiped mounted inside the differential casing and movable in the direction parallel to the rotational axis thereof, guides being made in the casing to guide said movements, the opposite radially disposed axles being in pairs rigidly interconnected while each of said pairs being angularly shiftable with respect to the other one in a plane passing through the rotational axis of the differential casing.
Claim 7
Dependent Claim
38 words
A differential according to claim 3, wherein in case if the ridially disposed axles of the spider are rigidly interconnected, each of said inserts comprises two bars disposed at the opposite sides of the respective radially disposed axles.
Claim 8
Dependent Claim
90 words
A differential according to claim 1, wherein the ring disposed inside the differential casing is made splitted and consists of wedge-shaped parts some of which engage the outer end faces of the satellites and confront them with the enlarge side thereof while the other parts of the ring are placed therebetween and have their enlarged sides adjoining the inner surface of the differential casing, those of the parts of the ring engaging the satellites being radially and angularly shiftable with respect to the differential casing along the rotational axis thereof.
Claim 9
Dependent Claim
51 words
A differential according to claim 7, wherein a screw mechanism is placed on the differential casing to adjust the working depth of teeth in mesh of the satellites with the bevel pinions, said mechanism being in contact with one of the ring parts positioned between the parts engaging the adjacent satellites.
