Title: Innovations of Hubert Landwehr
Introduction
Hubert Landwehr is a notable inventor based in Neuss, Germany. He has made significant contributions to the field of mechanical engineering, particularly in the design and functionality of screw presses. With a total of 2 patents to his name, Landwehr's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Landwehr's latest patents is a stroke limiting means for a friction clutch pressure piston in a screw press. This invention involves a hydraulic piston that engages a friction clutch, allowing for a constant piston stroke as the clutch wears. The design includes a metering piston and cylinder that trap pressure fluid, ensuring that the operating piston stroke remains consistent. Additionally, fluid flow to the operating cylinder is controlled by a normally closed valve, which opens based on the position of the metering piston. This mechanism prevents the clutch from being inadvertently locked in an engaged condition.
Another significant patent by Landwehr pertains to the screw press itself. This design features a flywheel connected to the press spindle via a friction coupling. The spindle is axially displaced in a nut mounted in the upper cross member of the press frame. The flywheel's external toothing corresponds to the maximum pressing stroke, and multiple pinions engage with this toothed rim. Each pinion is driven by oil-hydraulic axial piston motors, which are strategically placed on a platform surrounding the press frame. This innovative arrangement enhances operational reliability while reducing structural expenditure.
