Anatomie eines Zentralgetriebes: Optimierung des Kraftflusses

The central gearbox is the “torque commander” of the rotary tiller. Its function goes beyond simple transmission; it is a complex system of load management and kinetic conversion.

1. Die 90-Grad-Vektorverschiebung

The primary mechanical function is to convert the longitudinal rotational energy from the tractor’s PTO into a transverse rotation. This is achieved via a Spiral-KegelradsatzIm Gegensatz zu geraden Kegelrädern haben Spiralzahnräder gekrümmte Zähne, die allmählich ineinandergreifen.

This “progressive mesh” reduces impact stress by 30% and noise by 8dB, which is critical when operating at 1000 PTO RPM.

2. Dynamik der Drehmomentverstärkung

In heavy clay soil, high speed is less important than raw cutting force. The gearbox acts as a reducer. For example, with a 1:1.92 ratio, an input of 500 Nm at 540 RPM is converted into approximately 960 Nm at 281 RPM. This torque multiplication provides the “breakout force” needed to fracture compacted soil layers.

3. Das thermische Gleichgewicht

Heat is the silent killer. A gearbox operating at 60kW generates approximately 1.8kW of heat energy. In the “Tropical Series,” we manage this via an Erweiterter Ölsumpf Und Strahlungsrippen-Design.
