Description:

Cages formed without cutting are known, in which the guide and roller support once through a between the rolling elements », lying, appropriately shaped web is achieved, on the other hand, those in which guidance and mounting of the rolling elements can be achieved by separately arranged elements. The former cage also has the disadvantage that only a small number of rolling elements can be accommodated with a certain pitch circle diameter.

The following construction of a non-cutting formed Cage made of sheet steel or another suitable material according to Figures 1 to 3 for cylindrical roller bearings with rim guide on the inner ring, with the simplest structure, leaves the greatest possible number of rolling elements in a given Pitch circle diameter to. The webs (3), which are on a diameter outside the pitch circle, take over at the same time the radial guidance of the cage and the mounting of the rolling elements (l). When making this cage you can start both from a cylindrical piece of pipe and from a rolled, welded band, as is the case on the left which Figure 2 shows. By punching out the window (2), the extent of which in the circumferential direction is greater than the roll diameter must be, the webs (3) and the axial guide surfaces (6) generated. The leading edges (5) are followed by the following Deformation of the web edges generated. The holder of the rollers (l) and the permissible radial guide play of the cage on the rolling elements is determined by deformation directed radially inwards the lateral guide webs (4) and the associated reduction in size of the window in the circumferential direction after insertion the rollers achieved through the window (2), as the right part of Figure 2 shows. The deformation of the webs (4) is

selects that the axial cage guide on the rolling elements in the The area of the roller plane surfaces takes place in which the speed of rotation is low. To keep the friction as low as possible Hold 2JU, the guide surfaces (6) can be slightly convex be made curved.

So that bulges on the sharpest bending edge of the webs (4) cannot impair the axial guidance, in the windows a recess (7) is provided, which covers the area of the largest deformation covered.
