发明名称 Angle-measurement system and method for production of an angle-measurement system
摘要 In an angle-measurement system and a method for producing an angle-measurement system, the angle-measurement system includes a bearing assembly and a scanning head, the bearing assembly including a graduated ring, an outer ring and rolling bodies. Rolling surfaces are formed both on the graduated ring and the outer ring, the rolling surface of the graduated ring having a smaller path radius than that of the outer ring. Furthermore, the rolling surface of the outer ring is arranged opposite the rolling surface of the graduated ring, and the rolling bodies are disposed between the two rolling surfaces such that the bearing assembly is free of radial play. In addition, an angle scaling is applied directly onto the graduated ring such that a geometrical pattern of the angle scaling in a first region deviates from a geometrical pattern in a second region as a function of rotational eccentricities of the bearing assembly. The angle scaling is able to be scanned by the scanning head.
