Problems solved by technology

However, the leaf spring is always in contact with the vibrating member, so the desired frictional force may not be obtained due to effects such as wear
For this reason, the impact drive actuator described in Patent Document 1 may not operate stably for a long period of time.

Abstract

It has a displacement mechanism (3), a vibrating base plate (4), a moving member (10), and a first magnetic field that generates a magnetic field in such a manner that magnetic attraction or repulsive force acts in a direction opposite to the moving member (10). Generating mechanism (11), the moving piece (10) has a first magnetic yoke that guides the magnetic flux generated by the first magnetic field generating mechanism (11), so that the magnetic flux generated by the first magnetic field generating mechanism (11) is concentrated on the moving piece (11) 10) has a second magnetic yoke (12, 22) on the opposite side of the vibration base (4) to the side opposite to the moving part (10) on the surface opposite to the vibrating base plate (4). The second magnetic yoke (12, 22) is The yoke (12, 22) controls the magnetic field generated by the first magnetic field generating mechanism (11) so that the magnetic flux generated by the first magnetic field generating mechanism (11) is concentrated on the fixing member (20) regardless of the N pole or the S pole. On the side surface, the friction force acting between the moving part (10) and the vibrating base plate (4) is thereby controlled, and the moving part (10) is driven.

Description

Technical field [0001] The present invention relates to an inertial drive actuator that moves a moving member in a predetermined direction. Background technique [0002] There are known actuators (hereinafter, such actuators will be referred to as "impact drive actuators" or "inertia drive actuators") that supply serrations to an electromechanical conversion element coupled to a drive shaft. An actuator that uses waveform driving pulses to displace the drive shaft in the axial direction and move the moving component frictionally coupled with the drive shaft in the axial direction. [0003] This kind of impact drive actuator is disclosed in Patent Document 1. Figure 9 (a) is a diagram showing its structure. The vibrating member 103 is inserted into a hole opened in the rising portion of the supporting member 101 and is arranged to be movable in the axial direction of the vibrating member 103 . One end of the vibrating member 103 is fixed to one end of the piezoelectric ele...
