Abstract
A cylindrical roller cage includes an outer race, and inner race, a plurality of rolling elements arranged between the outer race and the inner race, and at least one cage having a plurality of locating pockets corresponding to the number of rolling elements. The cage is ring-shaped and is arranged in a groove in the outer race or the inner race. The cage is interrupted at least at one circumferential breakpoint to define two ends of the cage at the breakpoint that form a connection having at least two cooperating elements which interact in a complementary manner by way of an undercut as viewed in the circumferential direction. The axial direction of the elements forms an angle of 15° to 75° with the circumferential direction or tangent to the circumference at the breakpoint.
Claims21
A cylindrical roller bearing, comprising
- an outer race;
- an inner race;
- a plurality of rolling elements arranged between the outer race and the inner race;
- at least one cage having a plurality of locating pockets corresponding to the number of rolling elements;
- the cage being configured in a shape of a ring and being arranged in a groove in the outer race or the inner race;
- the cage being interrupted at least at one circumferentially located breakpoint to define two ends of the cage at the breakpoint, the two ends of the cage forming a hook-type connection having at least two cooperating hook elements which interact in a complementary manner by way of an undercut as viewed in a circumferential direction;
- and
- the hook elements extending in an axial direction forming an angle with a tangent to a circumference of the cage, the angle being between 15° and 75°.
A cylindrical roller bearing comprising
- an outer race;
- an inner race;
- a plurality of rolling elements arranged between the outer race and the inner race;
- at least one annular cage having a plurality of locating pockets in which are positioned the rolling elements;
- the cage being interrupted at least at one circumferentially located breakpoint to define two ends of the cage at the breakpoint, each end of the cage having an engaging element, with the engaging element at one cage end engaging the engaging element at the other cage end to secure together the cage ends;
- and
- the engaging elements extending in an axial direction forming an acute angle with a tangent to a circumference of the cage.
