DEVICE FOR DYNAMIC BALANCING OF ROTATING BODIES, ESPECIALLY OF GRINDING WHEELS

摘要

1. Apparatus for the dynamic balancing of rotating bodies, in particular grinding discs, by displacing a rotating correcting mass together with the body to be dynamically balanced, in which apparatus the correcting mass is provided with a cylindrical guide bore extending obliquely in relation to the axis of rotation of the apparatus and comprises a disc which cooperates with a nut for angular displacement of the correcting mass relative to a fixing member in a plane at right angles to the axis of rotation of the apparatus, the correcting mass also being connected to a displaceably mounted shaft for radial displacement of the mass, characterized in that the shaft (10), which extends into the obliquely disposed guide bore (6) of the correcting mass (2), terminates in a cylindrical ring (8), which has an axis which extends obliquely in relation to the axis of the shaft (10) and which coincides with the axis of the guide bore (6).
