Description

Wire cage for roller bearings Cages for roller bearings bent from wire can be used be used when the cage has essentially only the task of To keep rolling elements at a certain distance from each other. It's already a Wire cage known for ball bearings, which is designed in a meander shape and each rolling element in the form of a loop.

The disadvantage of this known wire cage is that the rolling elements are not held in both radialon directions. This well-known cage forms therefore, together with the rolling elements, there is no structural unit, which can be seen in handling and when installed in a bearing proves to be disadvantageous.

The invention has the task of creating a wire cage, in which the rolling elements are held in all directions. According to the invention this object is achieved in that each rolling element between two U-shaped brackets is added, the mutual distance is smaller than the rolling element diameter and whose legs are above and below the center circle of the rolling element run and also a smaller mutual distance than the rolling element diameter have, the two brackets receiving a rolling element at one of their ends with each other and at their other ends with those receiving the adjacent rolling elements Ironing are connected.

The twist cage according to the invention encompasses the spiral structure on all sides and thus forms an easy-to-use structural unit with them. He can adapt to the form be adapted to the respective rolling elements, regardless of whether they are balls, Cylindrical rollers, tapered rollers or barrel rollers are involved. Likewise, according to the invention Designed cage for both radial roller bearings and roller bearings for longitudinal movements insert.

In the accompanying drawings are two embodiments of the Invention shown and are described in more detail below. They show: Fig. 1 shows a wire cage according to the invention for a cylindrical roller bearing, FIG. 2 shows a wire cage according to the invention Wire cage for a ball bearing.

The wire cage shown in Figure 1 for a roller bearing comprises each rolling element 1 on both sides with two U-shaped brackets 2 and 3. The bracket 2 has the legs 4 and 5 and the bracket 3 has the legs 6 and 7. Both the Distance between the legs 4 and 5 and the legs 6 and 7, as well as the distance between the legs 4 and 6 and the legs 5 and 7 is smaller than the rolling element diameter. The legs 4 and 6 run above and the legs 5 and 7 below the rolling element center circle 8. One end of the two U-shaped brackets 2 and 3 are through the connector 9 connected to one another, while the other ends of the two brackets are connected by the wire sections 1iO and 11 the connection to the brackets receiving the adjacent rolling elements produce.

In Figure 2 is an embodiment of the invention for a ball bearing shown for longitudinal movements. For each rolling element 12 there are, in turn, two Brackets 13 and 14 are provided, which are looped in adaptation to the shape of the balls 12 are trained. The connecting web 15 is also adapted to the shape of the rolling element.

Claims (1)

Claim Wire cage for roller bearings, characterized in that each roller body is taken between two U-shaped brackets whose mutual distance is smaller is as the Wälzkörperaurchme sser and its legs above and below of the rolling element center circle and also a smaller mutual one Distance than the Wiizkörperdurchme sser, the two having a rolling element receiving bracket at their one ends with each other and at their other ends with are connected to the bracket receiving the adjacent rolling elements.
