20110185782 | FLOW FORM TOOL MANDREL - An apparatus includes a mandrel having a first end and a second end, the mandrel including a cavity formed therein, a pilot disposed in the cavity formed in the mandrel, a portion of the pilot extending outwardly from the first end of the mandrel, and an insert disposed in a channel formed in the mandrel and through an exterior surface of the mandrel, wherein a portion of the pilot abuts the insert and radial outward movement of the insert is caused by an axial movement of the pilot. | 08-04-2011 |
20110263374 | FLOW-FORMED DIFFERENTIAL CASE ASSEMBLY - A differential case assembly includes a differential case having an open end and a side wall with an interior surface. A plurality of major internal splines is formed on the interior surface of the side wall, The differential case assembly further includes a gear assembly with a retainer insert and a cross pin. The retainer insert is disposed adjacent the interior surface of the side wall between a pair of the major internal splines. The retainer insert has a hole formed therein. The cross pin has an end received in the hole of the retainer insert. The gear assembly is thereby aligned within the differential case. | 10-27-2011 |
20120000314 | FLOW-FORMED DIFFERENTIAL CASE ASSEMBLY - A differential case assembly includes a differential case and a pinless gear assembly. The differential case has an open end and a side wall with an interior surface. The pinless gear assembly includes a retainer insert and a side gear with a shaft extending outwardly therefrom. The retainer insert is disposed adjacent the interior surface of the side wall, The retainer insert defines at least a portion of an aperture that receives an end of the shaft to align the gear assembly within the differential case. | 01-05-2012 |
20120177879 | FLOW FORMED DRUM WITH A RETENTION RING AND A SUBSTANTIALLY BURR FREE TOOTH PROFILE - A flow formed part includes a first end, a second end, and a side wall extending therebetween. A reinforcing member is disposed around the second end. The side wall has a profile formed along an inner surface of the side wall. The profile is adapted to be substantially burr free after windows are formed in the sidewall. A method of making a flow formed part includes the steps of disposing a preform on a tailstock, providing a plurality of rollers adjacent the tailstock, providing a mandrel having an outer surface including a plurality of alternating channels and protuberances, and causing the rollers to press the preform against the outer surface of the mandrel. | 07-12-2012 |
20120325047 | FLOW-FORMED DIFFERENTIAL CASE ASSEMBLY - A differential case assembly includes a differential case and an integral end cap and ring gear assembly. The differential case has an open end and a side wall with an exterior surface. The integral end cap and ring gear assembly is disposed over the open end of the differential case and adjacent the exterior surface. A first interior portion of the integral end cap and ring gear assembly abuts the exterior surface of the differential case to define a weld joint interface. The integral end cap and ring gear assembly is configured to permit a welding operation at the weld joint interface. | 12-27-2012 |
20130264165 | TORQUE TRANSMITTING ASSEMBLY AND METHOD OF PRODUCING - A torque transmitting assembly is provided. The torque transmitting assembly includes a generally cup shaped outer shell having a closed end and an open end. The closed end has at least one raised portion formed therein. The outer shell includes an outwardly extending lip surrounding the open end of the outer shell. The open end of the outer shell is adapted to be operatively engaged with a first rotating member. A generally disk shaped inner member has a central aperture and a central axis. The inner member includes at least one tab extending axially outwardly therefrom and engages the raised portion of the outer shell to facilitate a transfer of rotation between the outer shell and the inner member. The central aperture is adapted to be operatively engaged with a second rotating member. The inner member is received inside said outer shell. | 10-10-2013 |
20140094337 | FLOW-FORMED DIFFERENTIAL CASE ASSEMBLY - A differential case assembly includes a differential case and a pinless gear assembly. The differential case has an open end and a side wall with an interior surface. The pinless gear assembly includes a retainer insert and a side gear with a shaft extending outwardly therefrom. The retainer insert is disposed adjacent the interior surface of the side wall. The retainer insert defines at least a portion of an aperture that receives an end of the shaft to align the gear assembly within the differential case. | 04-03-2014 |
