摘要:
A piezoelectric motor comprising: a piezoelectric vibrator (50) having a surface comprising a localized non-planar shaped first surface region thereon which first surface region has a shape different from the shape of the surface on which it is located; and a friction nub (52) formed with a second surface region that is substantially a negative relief of the first surface region, which first and second regions are bonded together. Preferably the friction nub (52) is detachably mounted to the vibrator (50) via a boss (54) waving a protuberance (56) of conical shape. Alternatively the friction nub (52) has a protuberance (76) which is form-fitted to a recess (72) in the vibrator (50) or boss (70), respectively. First and second surface regions can also be threading surfaces.
摘要:
A vibration actuator has a vibration member for generating a vibration, and a contact member which contacts the vibration member, and moves relative to the vibration member by the vibration generated by the vibration member. A portion of te vibration member, which is in sliding-contact with the contact member is formed as a separate first member, and the first member is coupled to the vibration member.
摘要:
Moteur à vibrations comportant un stator (1) et un rotor (4), ainsi que des moyens d'excitation pour déformer ledit stator (1) selon un mode vibratoire destiné à lui permettre d'entraîner en rotation le rotor (4), caractérisé en ce qu'il comporte un alliage à mémoire de forme, au niveau d'une zone de contact réciproque entre le rotor (4) et le stator (1).
摘要:
A vibration wave driven motor in which a vibration member and a member brought into pressure contact with the vibration member are frictionally driven relative to each other through a frictional material secured to the driving portion of one of them, characterized in that the frictional material is composed of a cermet.
摘要:
A friction material containing at least a rubber-like elastic body is provided between a vibrating stator (2) provided with a piezoelectric element (4) for producing travelling wave and a rotor of an ultrasonic motor. Noise is suppressed and motor capabilities such as driving torque and wear are fairly improved.
