Frictionless carriage for tire uniformity machine loadwheel carriage

摘要

In a tire uniformity machine of the type wherein a loadwheel is received on a carriage slidably mounted on the machine frame for movement toward and away from the tire, the frame and the carriage are interconnected by mounting plates, one attached to the frame and one attached to the carriage, and interconnected by precision anti-friction flatway linear motion bearings of the type characterized by cross rollers or balls mounted in anti-friction ways so as to facilitate movement of the carriage and stability thereof in two axes to insure precise positioning of the loadwheel relatively of the tire.
