PROCESS TESTING BALLS Russian patent published in 2003 - IPC

FIELD: measurement technology. SUBSTANCE: balls are placed between two supports arranged on body. Supports are rotated about their axis with speeds different in value and direction. Required parameters are measured in different non-repeated cross-sections. Several ball are measured at same time. More than one pair of cones which working surfaces in the form of grooves are arranged on outer butt of support are utilized for first support. Second supports which number corresponds to number of balls measured simultaneously come in the form of two independent cones set in motion and spring-loaded to balls. Speeds of balls in point of contact with cones of second supports are chosen different. Second supports are positioned uniformly over outer butt of first support with angular spacing sufficient to test balls. EFFECT: widened technological potential. 1 cl, 4 dwg
