Tire uniformity machine and method.

摘要

A machine for testing the uniformity of tires. The machine comprises: a test spindle (14) configured to receive a rim (16) supporting a tire (18); an index table (22) having a pair of index spindles (24, 26); indexing means (30) to rotate the index table whereby the index spindles may move a tire between an operator loading station (32) and an index station (34); a loader robot (36) adapted to move between the test spindle and the index station for transporting therebetween a tire; a roadwheel (44) movable between a retracted position out of contact with a tire and an advanced position in driving contact with a test tire; motor means (48) to rotate the roadwheel while in its advanced position; and transducer means (50) coupled to the test spindle to determine vibrations of the test tire when rotated by the roadwheel as caused by non-uniformities within the tire. Also disclosed is a method for testing tires as with the disclosed machine.
