Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
A planet pinion shaft retainer for a planetary gearset comprising, a planetary carrier, a planet gear, means defining a planet gear shaft opening in said carrier, a planet gear shaft mounted in said carrier rotatably supporting said planet gear, means defining a chordal pin opening in the outer peripheral portion of said planetary carrier intersecting the outer peripheral portion of the planet gear shaft opening, means defining a pin slot in the periphery of said planet gear shaft for alignment with said pin opening in said carrier, a retainer pin partially received in said pin opening of said carrier and in said slot of said planet gear shaft for locking said planet gear shaft iN axial and angular alignment relative to said carrier.
Claim 2
Dependent Claim
123 words
A planet pinion shaft retainer for a planetary gearset comprising, a planetary carrier, a planet gear, means defining a planet gear shaft opening in said carrier, a planet gear shaft mounted in said carrier rotatably supporting said planet gear, means defining a chordal pin opening in the outer peripheral portion of said planetary carrier intersecting the outer peripheral portion of the planet gear shaft opening, means defining a pin slot in the periphery of said planet gear shaft for alignment with said pin opening in said carrier, a retainer pin partially received in said pin opening of said carrier and in said slot of said planet gear shaft for locking said planet gear shaft iN axial and angular alignment relative to said carrier.
Claim 3
Dependent Claim
52 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 wherein said carrier defines fluid passages for transmitting lubricating fluid through said carrier, said planet gear shaft defines lubricating fluid passages in communication with said passages in said carrier for lubricating the bearing of said planet gear.
Claim 4
Dependent Claim
64 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 including means defining radial passages in said planetary carrier, means defining radial and axial passages in said planet gear shaft in communication with the radial passages of said carrier when said retainer pin aligns said planet gear shaft for transmitting lubricating fluid to the bearing of said planet gear.
Claim 5
Dependent Claim
49 words
A planet pinion shaft retainer for planetary gearset as set forth in claim 1 including, means defining passage means in said planet pinion shaft, means defining supply passages on said carrier for supplying lubricating fluid to said passage means in said planet pinions shaft for lubricating said planet pinion.
Claim 6
Dependent Claim
57 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 including means defining passages in said planet gear shaft, means defining radial passages in said planet gear for transmitting lubricating fluid from said planet gear shaft to the periphery of said planet gear for lubrication of the gears of said planetary gearset.
Claim 7
Dependent Claim
77 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 including means defining passages in said planetary carrier for transmitting lubricating fluid, means defining passages in said planet pinion shaft for transmitting lubricating fluid for lubrication of said shaft and said planet gear, a sun gear and drive shaft including means defining passages adapted for supplying lubricating fluid to the passage means in said planetary carrier for lubrication of said planetary gearset.
Claim 8
Dependent Claim
82 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 including, means defining lubricating fluid passage means in said planetary carrier, means defining an annular recess on the internal periphery of said planet carrier adapted for reception of lubricating fluid from a source of lubricating fluid, means defining lubricating fluid passages in said planet gear shaft for transmitting lubricating fluid from said cerrier to the external periphery of said planet gear shaft for lubricating, said planet gear.
Claim 9
Dependent Claim
89 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 including means defining a radial passage in said carrier adapted for transmitting lubricating fluid, means defining an axial and diametrical passages in said planet gear shaft for transmitting lubricating fluid for lubricating said planet gear, said means defining said pin slot communicating with one of said diametrical passages, said retainer pin thereby blocking transmission fluid through said diametrical passages to direct the flow of lubricating fluid through said passages in said planet gear shaft.
Claim 10
Dependent Claim
59 words
A planet pinion shaft retainer for a planetary gearset as set forth in claim 1 wherein said means defining said opening in said carrier defines a chordal opening in said carrier, said retainer pin and said carrier defining an interference fit to frictionally engage said retainer pin and maintain said pin in its fixed position in said planetary gearset.
