Abstract
Abstract A stationary sun gear mounted on a sleeve fixed to the transmission housing. The sleeve provides a bearing support internally and externally of the sleeve for rotatably mounting rotating members on the sleeve. The mounting of the gear and sleeve assembly permits individual replacement of the sun gear and support sleeve as well as servicing of the bearings.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A gear and bearing mounting in a transmission comprising, a transmission housing, a mounting sleeve connected to said housing defining a plurality of key slots, a bearing mounted externally on said sleeve, means for retaining said bearing on said sleeve, a second bearing mounted internally in said sleeve, a gear having a supporting flange defining a plurality of keyways and mounted in said sleeve, a plurality of keys mounted in said key slots of said sleeve and said keyways of said supporting flange for absorbing torque transmitted between said sleeve and said gear, fastening means holding said gear axially on said mounting sleeve, shoulders on said keys engaging said mounting sleeve for retaining said keys in said keyways and key slots.
Claim 2
Dependent Claim
121 words
A gear and bearing mounting in a transmission comprising, a transmission housing, a mounting sleeve connected to said housing defining a plurality of key slots, a bearing mounted externally on said sleeve, means for retaining said bearing on said sleeve, a second bearing mounted internally in said sleeve, a gear having a supporting flange defining a plurality of keyways and mounted in said sleeve, a plurality of keys mounted in said key slots of said sleeve and said keyways of said supporting flange for absorbing torque transmitted between said sleeve and said gear, fastening means holding said gear axially on said mounting sleeve, shoulders on said keys engaging said mounting sleeve for retaining said keys in said keyways and key slots.
Claim 3
Dependent Claim
60 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said fastening means includes means defining an annular recess in said supporting flange of said gear, means defining a radial hole in said mounting sleeve, a pin received in said radial hole and said annular recess to thereby lock said gear on said mounting sleeve.
Claim 4
Dependent Claim
49 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said means for retaining said bearing on said sleeve includes means defining an annular groove on said mounting sleeve, a snap ring received in said annular groove for retaining said bearing on said sleeve.
Claim 5
Dependent Claim
54 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said bearing mounted on the external periphery of said sleeve defines a bearing assembly for rotatably mounting a rotor, said second bearing mounted internally of said sleeve defines a needle bearing for rotatably mounting a shaft within said sleeve.
Claim 6
Dependent Claim
86 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said bearing mounted on the external periphery of said sleeve defines a tapered roller bearing, a rotor rotatably mounted on said bearings, said retainer means includes a snap ring fastening said bearings in normal operating position on said sleeve, said second bearing rotatably mounted within said sleeve defining a needle bearing for rotatably supporting said shaft to thereby provide rotatable support of said shaft on the concentric axis with said rotor.
Claim 7
Dependent Claim
49 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said flange defines at least four keyways, said mounting sleeve defines at least four key slots, four keys mounted in said key slots and keyways for concentrically supporting said gear on said mounting sleeve.
Claim 8
Dependent Claim
71 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said supporting flange of said gear defines an annular groove, said mounting sleeve defines a radial opening, a pin received in said radial opening and said annular groove for locking said gear on said sleeve, said bearing mounted externally of said sleeve holding said pin in the fastening position for holding said gear on said sleeve.
Claim 9
Dependent Claim
48 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein each of said keys define a shoulder portion positioned between the external periphery of said mounting flange and the internal periphery of said mounting sleeve for concentrically aligning said gear with said sleeve.
Claim 10
Dependent Claim
55 words
A gear and bearing mounting in a transmission as set forth in claim 1 wherein said key defines a shoulder portion positioned intermediate the supporting flange of said gear and said mounting sleeve to absorb radial thrust between said gear and said sleeve and said keys absorb torque transmitted between said gear and said sleeve.
Claim 11
Dependent Claim
50 words
A gear and bearing mounting in a transmission as set forth in claim 1 including means defining an annular recess and a radial surface on the external end at said mounting sleeve for receiving said supporting flange and engaging the inner end of said supporting flange in the assembled position.
