DEVICE FOR BALL BEARINGS' RACES' ORBITS PARAMETERS MEASURING

The invention applies to the field of measuring technology and applies to equipment for measuring the orbital parameters of ball bearing rings. The equipment is based on a foundation frame, a drive spindle with a carrier of measured ball bearing rings and three sensing units, provided with measuring contacts. The nature of the solution is based on the fact that two oppositely positioned sensing units (4, 5) are clamped in a holder (7) anchored to the foundation frame (1) of the equipment where, furthermore, another holder (8) is anchored with the third clamped sensing unit (6). Its measuring contact (61) is in touch with a table (9) to which the measured ball bearing ring (3) is placed and radially positioned. The table guide rod (91) is embedded in a rectilinear guide way with a rigid part anchored to the foundation frame (1) of the equipment and is set in an oscillating motion by a cam-operated or possibly an eccentric mechanism. The measuring contact (61) of the third sensing unit (6) may be in touch with the face of the measured ball bearing ring (8).
