Title: The Innovative Contributions of Karl Roll
Introduction
Karl Roll is a notable inventor based in Leinfelden, Germany. He has made significant contributions to the field of engineering, particularly in the development of advanced measurement technologies. With a total of six patents to his name, Roll's work has had a considerable impact on the design and functionality of power tools.
Latest Patents
One of Karl Roll's latest patents is a transducer for torque and/or angular displacement measurement. This innovative transducer arrangement operates based on the eddy current principle and is specifically designed for use in power screwdrivers. The transducer is constructed as a self-contained unit, featuring its own casing that connects to the screwdriver's housing and its driving and driven members. A torsionally deformable member, such as a shaft, is integrated between these members, allowing for joint rotation. When torque is applied, the end portions of the deformable member are angularly displaced, which influences the magnetic field in the vicinity. This change is detected by an electric coil arrangement, enabling the evaluation of the applied torque magnitude.
Another significant patent by Roll involves a motor-driven screwdriver. This screwdriver features a planetary gear carrier that supports multiple planet gears, which mesh with a pinion driven by the motor. The design includes a coupling element that can be moved by a fluid-operated piston, allowing for efficient operation and control of the screwdriver's rotation.
