APPROPRIATE CHOOSING THE CROSS-ROLLER RING FOR ROBOTIC APPLICATIONS
Cross-Roller Rings are the newest types of bearing, with optimal performances for high precision motion guidance mechanism in machine-tool and robotics design. The problem of choosing the appropriate size of the Cross-Roller Ring is very important to obtain maximum performances of the mechanical system which use this type of device. Based on specific operating conditions and data from the manufacturer’s catalog, this paper represents a practical algorithm that can be used by the designers in selecting the correct size and verification of the Cross-Roller Ring which satisfy the solving of the practical problem, in the better way.Key words: precision bearings, rigidity, high rigidity, robotics, Gantry robots
