Abstract

In the manipulator shown in Fig. 1, the X and Z axes are required to be aligned with one another. The alignment of the two points carrying the X- and Z-axis shafts is important, and any misalignment must be taken into consideration in calibrating or using the manipulator.

Dual Axis Linear Bearing

In the manipulator shown in Fig. 1, the X and Z axes are required to be aligned with one another. The alignment of the two points carrying the X- and Z- axis shafts is important, and any misalignment must be taken into consideration in calibrating or using the manipulator.

Referring to Fig. 2, there are shown the two joints 10 and 12 for the X- and Z- axis shafts 11 and 13, respectively. It should be noted that the joints are formed out of one housing 14. In other words, it is an integral housing with two joints for different axes included therein. It should be noted that once the housing 14 containing the two joints 10 and 12 is made or molded, there is no way this alignment, due to the housing, can change. Of course, some misalignment problems may be introduced by the incorrect mounting of the bearings which support the two shafts 11 and 13.
