Embodiment 1
[0078] For the vibrating gear of the vibrating gear and the vibrating tooth of the turntable, the second tooth surface adopts the conventional tooth surface generation form:
[0079] When the straight line R generated by the tooth surface does not intersect the rotation axis, the formula S R Both φ(t) and H(t) in (t)=φ(t)+H(t) are linear functions.
[0080] By drawing and processing the real object in this way, the torque of the relative rotation of the vibrating teeth is tested as follows:

Embodiment 3
[0093] When the straight line R generated by the tooth surface intersects the axis, the formula S R In (t)=φ(t)+H(t), φ(t) is a quadratic function, and H(t) is a linear function.
[0094] By drawing and processing the real object in this way, the torque of the relative rotation of the vibrating teeth is tested as follows:
[0095]
[0096]
[0097] Note: 10, 20 to 100 represent the average torque recorded every ten times.
[0098] It can be seen from the data that the torque of the second tooth surface generated in this way does not show an increasing trend as the number of vibrations increases, and the torque of the vibrating teeth relative to the rotation is relatively average, and the average value is moderate.
[0099] Disassemble the storage-type powder mist drug delivery device, and observe that the second tooth surface of each vibrating tooth is relatively complete. The reason for the analysis is that during the relative rotation of such a curved surface, the secon...
