AI Technical Summary
The mechanical clutch drive shaft generates a large impact force during the jaw engagement process, resulting in a short service life.
Design an active meshing gear structure for a mechanical clutch drive shaft. By adjusting the shape and structure of the bosses, the impact force during meshing is reduced. This includes setting the included angle of the first, second, and third inclined surfaces to 0-25°, distributing the bosses in a ring array on the body, and using a torsional curved surface design and control ring grooves to achieve transmission.
It extends the service life of the mechanical clutch drive shaft and reduces the impact force during engagement.
