1. A roller bearing cage for mounting rollers around a circle in a bearing, said roller bearing cage comprising:
two substantially semi-cylindrical halves of the cage cut from a cylindrical cage blank and re-assembled by connecting adjacent cut edges of each substantially semi-cylindrical half together, and
a plurality of pockets for mounting said rollers in the cage, each of said rollers having a center axis, a shape of each of the plurality of pockets or their positions being provided so that the position of said rollers in the respective pockets are such as to compensate for the material removed in the a cutting step, whereby the center axes of the rollers mounted in the pockets are set out on a circle centered on the cage axis, and
the pockets which are furthest from joints between the two substantially semi cylindrical halves of the cage are shaped such that radially innermost positions of the center axes of said rollers contained therein are further from an inner circumferential face of the cage than correspondingly radially innermost positions of the center axes for rollers in pockets which are closest to the joints between the two substantially semi-cylindrical halves of the cage.
2. The roller bearing cage of claim 1 wherein each of the plurality of pockets comprises a pair of end surfaces and first and second side surfaces.
3. The roller bearing cage of claim 2 wherein each of the first and second side surfaces comprises a first facet, wherein the first facet of the first side surface extends at an angle of about 15-25\xb0 to the facet of the second side surface.
4. The roller bearing cage of claim 2 wherein each of the first and second side surfaces includes a retaining lip located at a distal end of the respective side surface.
5. The roller bearing cage of claim 4 wherein the lip located at the distal end of each of the first and second side surfaces is positioned on a second facet located radically outwardly from a first facet.
6. The roller bearing cage of claim 1 further comprising a spring clamp for connecting the adjacent cut edges of each substantially semi-cylindrical half together.
7. The roller bearing cage of claim 6 wherein each of the plurality of pockets comprises a pair of end surfaces and first and second side surfaces.
8. The roller bearing cage of claim 7, wherein each of the first and second side surfaces of respective pockets comprise a first facet, wherein the first facet of the first side surface extends at an angle of about 15-25\xb0 to the facet of the second side surface.
9. The roller bearing cage of claim 8, wherein the first facets are arranged for respective pockets such that a roller contained within a pocket that is further from joints between the two substantially semi-cylindrical halves of the cage are further from an inner circumferential face of the cage than rollers contained in pockets closer to the joints.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A paper storage device comprising:
a paper storage section which stores paper;
an elevating plate which is vertically movable in the paper storage section;
a width regulating member which has a first engagement section, which has both ends thereof detachably supported on a bottom surface and a top surface of the paper storage section, and which projects further above a highest elevation position of the elevating plate; and
a positioning member which is arranged on the top surface of the paper storage section and which has a plurality of second engagement sections selectively engaging with the first engagement section on the width regulating member side and a plurality of scales which display paper sizes respectively corresponding to the second engagement sections,
wherein the positioning member is so arranged as to be horizontally inverted through 180 degrees, thereby permitting switching between positioning by the width regulating member corresponding to a metric paper size and positioning by the width regulating member corresponding to an inch-based paper size.
2. The paper storage device according to claim 1,
wherein the plurality of scales are provided on left and right of the second engagement sections separately for a metric paper size and an inch-based paper size, and when the first engagement section is engaged with the second engagement section in accordance with arrangement of the positioning member, the scale displaying the paper size corresponding to the second engagement section faces a mark line on the width regulating member side.
3. The paper storage device according to claim 1,
wherein, on both a left and a right ends of the positioning member, a direction indication line is provided which is aligned with a fitting reference line on the top surface of the paper storage section to determine arrangement direction of the positioning member.
4. The paper storage device according to claim 2,
wherein, on both a left and a right ends of the positioning member, a direction indication line is provided which is aligned with a fitting reference line on the top surface of the paper storage section to determine arrangement direction of the positioning member.
5. The paper storage device according to claim 1,
wherein the first engagement section and the second engagement section are engaged with each other with a predetermined clearance being provided therebetween in a moving direction of the width regulating member, and the width regulating member is slidably fixed to the positioning member within the clearance.
6. The paper storage device according to claim 2,
wherein the first engagement section and the second engagement section are engaged with each other with a predetermined clearance being provided therebetween in a moving direction of the width regulating member, and the width regulating member is slidably fixed to the positioning member within the clearance.
7. The paper storage device according to claim 3,
wherein the first engagement section and the second engagement section are engaged with each other with a predetermined clearance being provided therebetween in a moving direction of the width regulating member, and the width regulating member is slidably fixed to the positioning member within the clearance.
8. The paper storage device according to claim 1,
wherein the first engagement section is a positioning hole formed in the width regulating member, the second engagement section is a positioning projection formed in the positioning member and engaging with the positioning hole, and the width regulating member is provided with an opening for, when the positioning hole is engaged with any of the positioning projections, avoiding interference with the other positioning projections.
9. The paper storage device according to claim 1,
wherein relationship (inch-based paper size width)2+2L=(metric paper size width)2 is satisfied where a distance from a straight line passing through a rotational center of the positioning member and vertical to a movement direction of the width regulating member to any of the second engagement sections is L.
10. The paper storage device according to claim 9,
wherein the second engagement section satisfying the relationship (inch-based paper size width)2+2L=(metric paper size width)2 corresponds to a minimum inch-based paper size width and a maximum metric paper size width.
