AI Technical Summary
Technical Problem
Existing bearings in shuttle forming machines experience material fatigue and premature failure due to high-speed operation and repetitive loads, leading to increased maintenance and reduced productivity.
Method used
A bearing structure with an inner ring featuring slots and material bridges that distribute load evenly across rolling elements, reducing material fatigue and preventing premature failure.
Benefits of technology
The new bearing design extends the service life of components, enhances productivity, and reduces maintenance intervals by distributing load uniformly across rolling elements, thereby minimizing material fatigue.

Abstract
To provide a bearing for reducing the material fatigue of a machine.SOLUTION: A bearing (25) for a shed forming machine or a system for transmitting a motion to a frame of a loom comprises an inner ring (72), an outer ring (74) and rolling elements (76). The inner ring has two lateral surfaces vertical to a long axis and centered on a main axis line (A72), and defines a circular external peripheral ring (80) centered on the long axis line. The outer ring (74) defines the circular inner ring (72) centered on the main axis line. The inner ring (72) comprises at least one slot (90), is open onto the two lateral surfaces, extends opposite a part of the external peripheral ring (80), and forms a material bridge (94) between the slot and the external peripheral ring. The material bridge (94) extends above an angular sector (99) of the inner ring, the angular sector being centered on the main axis line (A72) of the bearing and having a vertex angle (α1) which is larger than a vertex angle (β2) of an angular sector occupied by the two rolling elements (76), or equal thereto.SELECTED DRAWING: Figure 4
