AI Technical Summary
Technical Problem
Existing drive elements and units face inefficiencies in force transmission and wear, leading to reduced lifespan and increased maintenance needs.
Method used
The drive element incorporates a resonator with contact elements made of different materials, featuring wear-suppression elements and prestress forces to enhance tribological properties and stabilize the contact surfaces, reducing wear and improving force transmission.
Benefits of technology
This configuration enhances the efficiency and extends the lifespan of the drive unit by minimizing wear and maintaining optimal operating quality.

Abstract
The driving element plays the role of driving the passive element (4) relative to the active element (1). The active element (1) comprises a resonator (2), an vibration excitation means (23), and at least one arm (21), the arm (21) extending in the arm direction (21a) and having a contact element (31) at its outer end that is movable by the vibrational motion of the arm (21) in order to drive the passive element (4). The arm (21) has a contact element (31) at its outer end that drives the contact area (41) of the passive element (4). At least one of the following conditions is met: the contact element (31) includes an insert (80) made of a material different from the material of the resonator (2), particularly a material harder than the material of the resonator (2); the first wear suppression element (83) is placed on the contact element (31) and the second wear suppression element (84) is placed on the passive element (4) in the contact area (41); and the passive element (4) is made of a wear suppression material.
