Title: Max Vollenweider: Innovator in Piezoelectric Technology

Introduction

Max Vollenweider is a notable inventor based in Winterthur, Switzerland. He has made significant contributions to the field of piezoelectric technology, holding a total of three patents. His work focuses on innovative solutions for measuring strain and balancing rotating bodies.

Latest Patents

One of Vollenweider's latest patents is a piezoelectric strain transducer. This device is designed to be attached to a test specimen or machine part using a single locking screw. The transducer features two bearing surfaces that bear frictionally on the machine part's surface. When the machine part experiences a change in length, the spacing between these surfaces changes, which tensions a resilient member. This member is adaptable to the desired sensitivity of the gauge. The piezoelectric plates within the transducer respond solely to shearing forces, providing a measurement of the strain or mechanical stress on the machine part. This technology is particularly useful for monitoring or controlling machines subjected to cyclic loads.

Another significant patent is for a balancing and monitoring apparatus. This device is designed for balancing rotating bodies and includes a sensing arrangement to detect any imbalance. It utilizes an abrasion tool that operates at a frequency corresponding to the speed of the rotating member. This tool removes material from the rotating member in phase with the working vibration, effectively balancing the member. The apparatus also features an adjusting arrangement that allows for phase relationship adjustments, enabling precise balancing irrespective of the rotating member's speed.
