Chain for rolling elements

摘要

A chain for rolling elements includes a carrier belt having first and second side strip on two sides thereof, and multiple holes are defined in the carrier belt and located between the first and second side strips. Each hole has a first opening end and a second opening end. Multiple retainers are connected to the carrier belt and located alternatively with respect to the holes. Multiple first ribs are connected between the first side strip and the retainer. Multiple second ribs are connected between the second side strip and the retainer. Each of the first and second side strips has a thickness T1, and each of the first and second ribs has a thickness T2 which is smaller than T1. The first and second ribs reinforce connections between the first and second side strips and the retainers so that the chain has even flexibility and can operate smoothly.

1. A chain for rolling elements, comprising:
a flat carrier belt having a first side strip and a second side strip on two sides thereof, multiple holes defined in the carrier belt and located between the first and second side strips, each hole having a first opening end and a second opening end, multiple retainers connected to the carrier belt and located alternatively with respect to the holes, multiple first ribs connected between the first side strip and the retainer, each of the first ribs located adjacent the hole corresponding thereto, multiple second ribs connected between the second side strip and the retainer, each of the second ribs located adjacent the hole corresponding thereto, each of the first and second side strips having a thickness T1, and each of the first and second ribs having a thickness T2 which is smaller than T1, wherein the thickness of each of the first ribs increases from the first opening end toward the second opening end of the hole corresponding thereto, the thickness of each of the second ribs increases from the second opening end toward the first opening end of the hole corresponding thereto.
