Embodiment Construction
[0009] As can be seen from Figure 1, the structure of the ultrasonic motor used for a single monitor pan / tilt is that the bearing cap 1 is connected to the upper end surface of the housing 3 by screws, the piezoelectric ceramic sheet 12 is pasted on the upper surface of the stator 4, and the stator 4 is placed in the housing. The body is installed on the boss in the middle of the upper end of the housing 3 through screws, the rotor 5 placed under the stator 4 is fixed on the output shaft 13, and a gasket 10 is installed between the spring leaf 11 installed on the output shaft and the rotor 5 , the upper and lower ends of the output shaft 13 are respectively supported on the bearing cover 1 and the base 8 through bearings, so that the movement is more stable and reliable. The output shaft 13 is hollow and can pass through wires, which solves the problem of winding when the pan / tilt rotates. The outer diameter of the shaft There is a pair of symmetrical keyways, as shown in Figur...
