Abstract

The present invention relates to a clip-chain module of rolling unit, which structure had the spacers, the end-part and the link-belt. The characteristic of the clip-chain module of rolling unit was made up of one or upward half clip-chains, thereby can reduce the friction of the rolling element and improve the difficulty of the process. Therefore, this invention can enhance the competitiveness of this product.

Claims

1. A clip-chain module of rolling unit for sequentially spacing a plurality of rolling elements and generally comprising:

plural spacers for spacing out the rolling elements, every paired neighboring spacers defining an interval therebetween for accommodation of a rolling element respectively as well as permitting for rolling of the same therein;

end parts defined at both sides of the clip-chain module of rolling unit for confining the rolling elements in the clip-chain module of rolling unit;

a link-belt for connecting the end-parts and spacers together;

the above-mentioned clip-chain module is a combination of half clip-chains, the half clip-chains each having the spacers, end parts and link-belt.

2. The clip-chain module of rolling unit as claimed in claim 1, wherein the spacers of the half clip-chains each have an engaging portion for enabling the respective spacers to engage with each other.

3. The clip-chain module of rolling unit as claimed in claim 2, wherein the each engaging portion of the spacers is additionally provided with a fixing device, which configured in the form of pins, rib or splines, whereby to prevent the disengagement of the half spacers from each other.

4. The clip-chain module of rolling unit as claimed in claim 1, wherein the spacer of each half clip-chain is provided with a supporting portion which extending outward with a specific angle, so as to receive the rolling element by manner of point-contact.

5. The clip-chain module of rolling unit as claimed in claim 1, wherein the intervals between each paired neighboring spacer are configured for matching with the shape of the rolling elements so as to free the rolling elements from interference, the link-belt for connecting the end parts are flexure-formed whereby to have a better flexibility.

6. The clip-chain module of rolling unit as claimed in claim 1, wherein the end parts can be coupled with each other, such that two or upward half clip-chains can be combined together so as to form a complete clip-chain module of rolling unit with desired length.

7. The clip-chain module of rolling unit as claimed in claim 1, wherein a central end part is formed in the middle of the half clip-chains, the spacers at both sides of the central end part are balanced in quantity, the end parts at both ends of the half clip-chains can be coupled with each other, whereby two or upward half clip-chains can be combined together so as to form a complete clip-chain module of rolling unit.

8. The clip-chain module of rolling unit as claimed in claim 1, wherein the rolling elements are balls.

9. The clip-chain module of rolling unit as claimed in claim 1, wherein the rolling elements are rollers.
