GC-A Roller Type Overrunning One Way Clutch 20 - 95 Mm

When the roller-type one-way clutch is working, the maximum contact stress occurs at the contact point between the roller and the inner and outer rings. Strictly speaking, because the force on both sides of the roller is equal, and its contact area with the convex surface of the inner ring is smaller than the contact area with the concave surface of the outer ring, the maximum contact stress occurs on the contact surface between the roller and the inner ring. Here, the most prone to occur is surface fatigue wear, and the typical failure form is pitting and spalling. The metal materials used to manufacture the one-way clutch rollers and inner and outer rings are generally the same as the rolling bearing materials.
When the one-way clutch is working, the roller is always subjected to the rotating centrifugal force, so it always tries to deviate from the point of contact with the periphery. Therefore, the roller must be pressed to the small end of the open groove with the help of a spring to prevent this deviation, which is why the spring is required to have a certain pre-tightening force.
