Abstract
The apparatus includes measuring heads having contacts cooperating with points of the openings of the cage and a processing unit connected to the measuring heads. The processing unit provides signals indicating the positions of the central points of the openings, determines a reference geometric plane which is the plane nearest, on the average, to the central points and determines the distances of the central points from the reference geometric plane.

Apparatus for checking the cage of a constant velocity joint, said cage having an outer wall with openings for housing the joint balls, comprising:
- first support means for supporting the cage;
- checking means;
- second support means, coupled to the first support means, for supporting the checking means;
- the checking means comprising checking elements for cooperating with points along the periphery of the openings, the checking means providing signals corresponding to the positions of the points with respect to the second support means;
- and processing means connected to the checking means;
- the processing means including first and second processing circuits, the first processing circuits being adapted to process the signals provided by the checking means for providing signals representative of the positions of the central points of the openings, the second processing circuits being connected to the first processing circuits for defining a reference geometric plane with respect to the relative positions of the central points and for providing measurement signals substantially representative of the distances of said central points from the reference geometric plane whereby the coplanarity of the central points is checked.
Apparatus for checking the cage of a constant velocity joint, said joint having an outer wall with openings for housing the joint balls, comprising:
- first support means for supporting the cage;
- checking means;
- second support means, coupled to the first support means, for supporting the checking means;
- the checking means comprising checking elements cooperating with points of the periphery of the openings, the checking means providing signals indicative of the positions of these points with respect to the second support means;
- and processing means connected to the checking means, the processing means processing the signals provided by the checking means for providing signals substantially representative of the positions of the central points of the openings and for defining a reference geometric plane relative to the positions of the central points, the processing means further providing measurement signals substantially representative of the distances of the central points from the reference geometric plane for checking the coplanarity of the central points.
A method for checking the cage of a constant velocity joint having an outer wall with openings for housing the joint balls, comprising the steps of determining the positions of the central points of the openings, determining a reference geometric plane depending on the determined positions of the central points of the openings and determining the distances of said central points from the reference geometric plane, whereby the coplanarity of the central points is checked.
