Abstract:
PROBLEM TO BE SOLVED: To provide a method of assembling a one-piece metallic ball bearing cage. SOLUTION: This method of assembling a ball bearing assembly is achieved through a step of forming the one-piece metallic ball bearing cage having a bridge portion between ball pockets, at least a portion of the bridge portion having a predetermined chordal length; a step of positioning bearing balls in an annular space between an inner ring and an outer ring and separating the bearing balls by an average chordal distance less than the predetermined chordal length; and a step of inserting the ball bearing cage into the annular space such that circumferential movement of the bearing balls allows the bridge portion of the ball bearing cage to pass between the adjacent bearing balls as the bearing balls sequentially enter the ball pockets.

Abstract:
Two thrust washers, and rollers positioned between them, are held together as an assembly. One of the thrust washers has an elongated lip extending an axial length outwardly, in a direction away from the rollers and the other thrust washer, for engagement with a cylindrical piloting surface of a backup member such that piloting will be provided over an axial distance equal to the sum of the distance between thrust surfaces of the thrust washers and the axial length of the elongated lip.
Abstract:
A first race component includes a flat, circular raceway portion, defined about an axis, and an axially extending lip portion. A plurality of needle rollers is arranged radially with respect to the axis for rolling contact with the flat raceway. A bearing cage retains the needle rollers and is engageable with the lip portion of the first component for piloting of the bearing cage. A second race component, made of different material, includes a flat portion in contact with the raceway portion of the first race component and a lip portion extending axially and radially from the flat portion and beyond the lip portion of the first race component such that the second race component is engageable by the bearing cage to hold the first race component, the second race component and the bearing cage together as an assembly.
Abstract:
A thrust bearing assembly comprising first and second thrust race members ( 52, 60 ) and a roller assembly ( 22 ) positioned therebetween. The first thrust race member ( 52 ) includes a radial race surface ( 53 ), a flange extending from the race surface and a radial lip ( 54 ) extending radially beyond the flange ( 56 ). The second thrust race member ( 60 ) includes a radial race surface ( 61 ) and a piloting flange extending from the race surface and includes a retaining lip ( 64 ). The second thrust member ( 60 ) is positioned within the first thrust member ( 52 ) radial lip ( 54 ) and retained thereby and there is a clearance between the retaining lip ( 54 ) and the first thrust race member flange ( 56 ) external surface.
Abstract:
A clamp yoke formed from a flat piece of metal. The flat piece being approximately T-shaped which is bent into the clamp yoke. The top portion of the T forming the yoke ears and the vertical portion forming two approximately parallel shaft portions. The yoke ears each having a bearing bore therein and the shaft portions each having a shaft receiving bore therein. The clamp yoke can be provided with a bolt having a reduced diameter middle which allows a shaft to be inserted into the shaft receiving bores without removing the bolt. The bolt is then tightened, drawing the larger diameter portion into the center of the clamp yoke where the bolt engages a transversely relieved portion on the shaft to axially retain the shaft.
Abstract:
An antifriction element (1) for use between two relatively sliding metal components (2, 3) of an adjustable steering column is locatable between the two components and is formed such that, in an unclamped state of the components, two opposed resilient flanges (7) act to urge the components away from contact with one another to allow relative free sliding of the components on the element (which is of plastics material) and, in a clamped state of the components, the flanges are deflected to allow direct contact between surfaces of the metal components to provide the clamping friction.
Abstract:
A fluid seal (16) is joined to a seal carrier (14), and a magnetoresponsive sensor (18) is coupled to a carrier to sense the polarities of a magnet (24) borne on a rotatable shaft (22). The seal carrier (14), with the incorporated sensor (18), is arranged about the shaft, and leads (20) from the sensor (18) transmit an output signal voltage which corresponds to, or is proportional to the speed of rotation of the shaft. Depending upon the type of sensor employed, the signal voltage will be of repeatedly changing amplitude (i.e., pulsed or sine wave), or of given amplitude, in which the signal goes from zero to the given amplitude, to zero cyclically, or the sine wave amplitude/voltage increases with increasing speed, or pulse widths which diminish with speed acceleration.
