AI Technical Summary
Technical Problem
Existing wedge-type overrunning clutches require additional safety devices during manufacturing, which complicates the process and may affect the reliability of the connection due to thermal expansion.
Method used
The safety device is formed by a protrusion integrally constructed with the outer ring, manufactured by deep drawing and stamping methods. The protrusion is axially distributed on the end face of the outer ring and can be bent to match the limit torque requirements.
Benefits of technology
It simplifies the manufacturing process of the wedge-type overrunning clutch and improves the reliability and torque resistance of the connection.
