Abstract
Abstract A planetary carrier assembly for a transmission in which the support for the planet pinions is provided by a preassembled sheet metal part formed of a support member, a spacer and a plate member secured together by welding. Aligned holes are bored in the three parts after welding to accommodate shafts for the pinions, thrust bearing washers being located between the planet gears and the support and plate members. The pinions are secured by an upsetting operation on the plate member and the support member at adjacent the ends of the pinion shafts.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
A planetary carrier assembly comprising a sheet metal plate member having a sheet metal spacer welded thereto at one end of said spacer; a support plate welded to said spacer at the other end thereof, said spacer, plate member and support plate having aligned apertures therethrough, said apertures receiving pinion supporting shafts on which are mounted planetary pinion gears, and including thrust bearings located between said pinion gears and said assembly on either side of said pinion gears.
Claim 2
Dependent Claim
78 words
A planetary carrier assembly comprising a sheet metal plate member having a sheet metal spacer welded thereto at one end of said spacer; a support plate welded to said spacer at the other end thereof, said spacer, plate member and support plate having aligned apertures therethrough, said apertures receiving pinion supporting shafts on which are mounted planetary pinion gears, and including thrust bearings located between said pinion gears and said assembly on either side of said pinion gears.
Claim 3
Dependent Claim
28 words
An assembly according to claim 1 in which said pinion shafts are secured in said assembly by deformed portions of said assembly adjacent either end of said shafts.
Claim 4
Dependent Claim
16 words
An assembly according to claim 2 in which the ends of said pinion shafts are chamfered.
Claim 5
Dependent Claim
46 words
An assembly according to claim 1 in which said plate member forms a generally radial end wall of a drum having an axially extending portion including axially extending lugs around the periphery thereof, said lugs adapted to form a torque transmitting connection with a mating support.
Claim 6
Dependent Claim
51 words
An assembly according to claim 4 wherein said axially extending portion with axially extending lugs is located at the radially outer edge of said radial end wall, and a second axially extending wall is located at the radially inner edge of said end wall, in the form of a cylindrical hub.
Claim 7
Dependent Claim
35 words
An assembly according to claim 1 wherein radial grooves are formed in said spacer and support plate at the location of said pinion shafts to act as lubrication passages for oil to lubricate said pinions.
