Portable high-rigidity mandrel

Abstract

The utility model discloses a portable high rigidity mandrel relates to mechanical transmission component technical field, including mandrel main part, metal insert and axial strengthening rib, the mandrel main part is hollow cylindrical, and mandrel main part is carbon fiber composite material mandrel, both sides inside of mandrel main part all is equipped with metal insert, two the metal insert is respectively with the inside interference fit connection of mandrel main part both sides, the inside surface of mandrel main part evenly installs a plurality of axial strengthening rib, and both sides of a plurality of axial strengthening rib respectively with two metal insert one side fixed connection. The utility model discloses a mandrel to carbon fiber composite material as main body material, cooperate hollow cylindrical structure, compared with traditional metal solid mandrel, can reduce self weight greatly, effectively reduce the inertia force that generates when high -speed operation, reduces the energy consumption of drive system, avoids the interference of inertia force to transmission accuracy.
