Abstract
Abstract In cage and roller combinations suitable for operation between inner and outer members to form a bearing, a cage guided on its outside diameter is produced by forming a blank having thickened rim portions at the ends, relieved relatively thin portions inwardly of the rim portions, thickened guiding portions and outward retaining portions inwardly of the relieved portions and a relatively thin midlength portion, then punching windows with parallel sides from the midlength portion, the guiding and outward retaining portion and the relieved portion but not entering the rim portions, the windows being relatively wide at the ends and relatively narrow at the middle, and then coining the crossbars desirably simultaneously to form lips at the guiding and outward retaining portions near the outside while retaining parallel sides at the guiding portions near the pitch diameter, and to displace metal from the midlength portions so as to form inwardly converging sidewalls which will clear the rollers and prevent escape of the rollers inwardly. The invention may provide cage-and-roller combinations in which a single roller in a window is guided adjoining the pitch circle near the end, the guiding portion outwardly converges to retain the roller against outward motion, and the window at the end terminates short of the rims.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A roller-and-cage combination for use in a bearing, the cage comprising rims and crossbars extending between the rims and separating the cage into windows, and rollers guided by the cage and positioned with a single roller in each window, the rims being relatively thick with respect to the roller diameter and having guiding surfaces adapted to guide at the outside, the windows terminating short of the rims at each end, the crossbars having at their ends areas of reduced thickness, toward the midlength area from the end, guiding and outward retaining areas, and at the middle, inner retaining areas, the guiding and outward retaining areas providing guidance for the rollers adjacent the pitch diameter and the guiding and outward retaining areas outside the pitch diameter having relatively converging lips which prevent the roller from escaping from the window outwardly, the crossbar at the midlength area having a spacing from the adjoining crossbar at the opposite side of the window which is too small to permit escape of the roller inwardly, and having a diverging shape in the inward direction adjoining the adjacent rollers.
Claim 2
Dependent Claim
183 words
A roller-and-cage combination for use in a bearing, the cage comprising rims and crossbars extending between the rims and separating the cage into windows, and rollers guided by the cage and positioned with a single roller in each window, the rims being relatively thick with respect to the roller diameter and having guiding surfaces adapted to guide at the outside, the windows terminating short of the rims at each end, the crossbars having at their ends areas of reduced thickness, toward the midlength area from the end, guiding and outward retaining areas, and at the middle, inner retaining areas, the guiding and outward retaining areas providing guidance for the rollers adjacent the pitch diameter and the guiding and outward retaining areas outside the pitch diameter having relatively converging lips which prevent the roller from escaping from the window outwardly, the crossbar at the midlength area having a spacing from the adjoining crossbar at the opposite side of the window which is too small to permit escape of the roller inwardly, and having a diverging shape in the inward direction adjoining the adjacent rollers.
Claim 3
Dependent Claim
22 words
A roller-and-cage combination of claim 1, in which the crossbars and the rims extend straight in the axial direction at the inside.
Claim 4
Dependent Claim
23 words
A roller-and-cage combination of claim 1, in which the thickness of the rim is between 60 and 95 percent of the roller diameter.
Claim 5
Dependent Claim
66 words
A roller-and-cage combination in claim 1, in which the guiding and outward retaining areas of the crossbar have a thickness between 55 and 95 percent of the roller diameter and the areas of reduced thickness at the ends of the crossbar adjoining the rim have a thickness at least 20 percent of the roller diameter less than the thickness of the guiding and outward retaining areas.
Claim 6
Dependent Claim
29 words
A roller and cage combination of claim 1, in which the midlength area of the crossbar has a thickness of between 30 and 50 percent of the roller diameter.
Claim 7
Dependent Claim
158 words
A cage for use in a roller and cage combination, comprising relatively thick rims at the opposite ends which are guiding surfaces adapted to guide on the outside diameter, crossbars connecting the rims and providing intervening windows adapted to guide and retain a single roller in each window, each crossbar having adjacent its ends and interposed between the crossbar and the rim a section of reduced thickness, then toward the midlength area at each end a guiding section of increased thickness, and then in the midlength inner retaining area of reduced thickness, the guiding portions at each side of the window having parallel sides adapted to guide the roller adjacEnt the pitch diameter and outwardly thereof having converging lips which retain the roller against escape outwardly, the area at the midlength having less distance across the window than the guiding portion and having at opposite sides of the window converging sides which retain the roller against escaping inwardly.
Claim 8
Dependent Claim
158 words
A cage for use in a roller and cage combination, comprising relatively thick rims at the opposite ends which are guiding surfaces adapted to guide on the outside diameter, crossbars connecting the rims and providing intervening windows adapted to guide and retain a single roller in each window, each crossbar having adjacent its ends and interposed between the crossbar and the rim a section of reduced thickness, then toward the midlength area at each end a guiding section of increased thickness, and then in the midlength inner retaining area of reduced thickness, the guiding portions at each side of the window having parallel sides adapted to guide the roller adjacEnt the pitch diameter and outwardly thereof having converging lips which retain the roller against escape outwardly, the area at the midlength having less distance across the window than the guiding portion and having at opposite sides of the window converging sides which retain the roller against escaping inwardly.
Claim 9
Dependent Claim
46 words
A cage of claim 6, in which is straight in the axial direction across the inside of each crossbar and the adjoining rims. 8 A cage of claim 6, in which the rims have a thickness of between 60 and 95 percent of the roller diameter.
Claim 10
Dependent Claim
55 words
A cage of claim 6, in which the guiding portions have a thickness of between 55 and 95 percent of the roller diameter and the reduced portions at the ends of the crossbars have a thickness which is at least 20 percent of the intended roller diameter less than the thickness of the guiding portion.
Claim 11
Dependent Claim
26 words
A cage of claim 6, in which the crossbar at the midlength portion has a thickness of between 30 and 50 percent of the roller diameter.
