Anatomi Kotak Gigi Sentral: Merekayasa Aliran Daya

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. Pergeseran Vektor 90 Derajat

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 Set Roda Gigi Bevel SpiralBerbeda dengan roda gigi bevel lurus, roda gigi spiral memiliki gigi melengkung yang saling bertautan secara bertahap.

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

2. Dinamika Perkalian Torsi

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. Kesetimbangan Termal

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 Bak Oli yang Diperluas Dan Desain Sirip Radiant.
