Mechanical four-gear group for pressureless force application of a clamping force within the ''Mechanical device unit for converting a linearly directed spring force into a rotational force movement'

Abstract

Mechanical four-gear assembly for the pressureless application of a clamping force within the "Mechanical device unit for converting a linearly directed spring force into a rotary force movement" (DE 10 2023 002 008 A 1 2024.11.28). The solution presented consists of a four-part gear assembly. This assembly is formed either from four gears of the same dimensions or from two gears with larger and two gears with smaller diameters. Of the two gear assemblies mentioned, one special gear is doubled with a lower gear. This lower gear is exclusively meshed with the existing spring force guide gear of the device unit. Its connection to the spring force guide gear is tangentially frictional and, as the only gear in the assembly, is positioned on the lever arm of the spring force guide gear. The other three gears are frictionally guided on the lower part of the support rod by means of retaining rods. Each of these four gears is coupled to a gear of the same diameter or a smaller diameter.The insertion of the wheel assembly presents two possibilities. The applied support rod force is transmitted directly via the three upper wheels without any pressure influence on the double wheel, which is toothed with the spring-loaded guide wheel. The second option for integrating the wheel assembly lies in the area of ​​the spring-loaded cross gear. This functionally important wheel assignment is solely responsible for ensuring the continuous positioning of the support rod in its rotating holding function for the upper support rod section using two lever forces. In both of the illustrated assignment variants, the acting contact force of the support rod is transformed into a tangentially pulling rotational force in the wheel web of the main wheel.
