ABSTRACT:
Apparatus for checking linear geometric dimensions of the raceway of a ball bearing ring. A base supports a rotatable plate, which makes a ring rotate about its geometrical axis, and a mobile arm which applies to gauging heads a reciprocating motion along the transversal direction of the raceway. The gauging heads have relevant feelers which, due to the motion of the gauging heads and the rotation of the ring, contact the raceway surface along lines having an oscillating form. The gauging heads provide signals responsive to the radial dimensions of the ring in correspondence with the raceway. The signals provided by the gauging heads are processed by electronic circuits for obtaining signals responsive to said geometric dimensions, for example signals indicating the raceway minimum diameter.
