Filed:

May 27, 1975

Appl. No.:

5/580618

Inventors:

James N. Diederich - Dayton OH

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F16C 3374

US Classification:

308 26

Abstract:

A housing and bearing assembly in which an ocillating shaft is rotatably supported. Two bearings are positioned in the housing to provide said support. One of the bearings is located in a small diameter portion of the housing and may be retained therein by a circumferential protuberance formed in the housing. The other bearing is pressed into a larger diameter portion of the housing which has a plurality of tapered or other geometric shaped ramps formed therein. As the bearing abuts the ends of the ramps during assembly, the ramps shear from the housing to form axial columnar supports for the bearing to prevent further intrusion of the bearing into said housing after the desired bearing position is attained by the pressing operation.

Abstract:

A mounting for a windshield wiper pivot shaft on a vehicle body panel supports the shaft for rotation about an axis of the panel. The mounting includes a transmission housing adapted to be rotatably seated on a first side of the panel. A key on the transmission housing and an associated keyway in the panel limits housing rotation in a first direction to a mounting position wherein an axis of the housing is aligned with the axis of the panel. The key has a retention surface which engages the panel to limit axial movement between the housing and the panel when the housing is in the mounting position, thereby passively retaining the housing to the panel. In one embodiment, a plurality of screws are installed from a second side of the panel opposite the first side and threadingly engage the housing. The screws are tightened in the first direction to rigidly fix the transmission housing to the panel, thereby maintaining the housing in the mounting position.
