Anatomie van een centrale versnellingsbak: het optimaliseren van de krachtoverbrenging

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. De vectorverschuiving van 90 graden

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 Spiraalvormige kegeltandwielsetIn tegenstelling tot rechte kegeltandwielen hebben spiraaltandwielen gebogen tanden die geleidelijk in elkaar grijpen.

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

2. Dynamiek van koppelvermeerdering

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. Het thermisch evenwicht

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 Vergrote oliecarter En Radiant Fin Design.
