Abstract

A retaining device for rolling-element includes the partition and the link-belt. The characteristic of the retaining device for rolling-element is that the partition is linked to form a ring by the link-belt, then the ring is turned in to form a space for retaining the rolling-element, so as to reduce the friction of the rolling-element.

Claims

1. A retaining device for rolling-element, in which plural rolling-elements being sequentially retained, which comprising:

partitions serving to separate the rolling-elements;

link-belt, which employed to link the partitions together;

wherein the link-belt links the partitions together to form a ring structure, a section of the ring structure being connectable to an opposite side portion of the ring structure, so as to make each two corresponding partitions butt-join together, the butt-joined partitions and the link-belt form a space, in which the rolling-element is rotatably retained.

2. The retaining device for rolling-element as claimed in claim 1, wherein the ring structure is provided at both ends with an end-part respectively after it is inwardly turned, so as to retain the rolling-elements securely in the retaining device.

3. The retaining device for rolling-element as claimed in claim 2, wherein the partitions are firmly butt-joined together by a bayonet joint.

4. The retaining device for rolling-element as claimed in claim 1, wherein the ring structure is turned in to form a structure having a curvature, and the curvature is not smaller than that of a circulating tack of the rolling-elements.

5. The retaining device for rolling-element as claimed in claim 4, wherein the partitions are firmly butt-joined together by a bayonet joint.

6. The retaining device for rolling-element as claimed in claim 1, wherein the partitions form a passage after they are butt-joined together, a space of the passage can expand or contract for allowing easy flow of lubricant through the passage.

7. The retaining device for rolling-element as claimed in claim 6, wherein the partitions are firmly butt-joined together by a bayonet joint.

8. The retaining device for rolling-element as claimed in claim 1, wherein the partitions are firmly butt-joined together by a bayonet joint.
