When the rotating part rotates, it forms a line contact with the raised ribs. The contact area is small, which can greatly reduce The mutual friction between them is reduced, the rotation is smoother, the transmission efficiency is faster, and the friction noise between them can also be reduced. It can also reduce the wear between the bearing part and the raised ribs, effectively prolong the service life and improve the working performance. more stable.
