중앙 기어박스의 구조: 동력 흐름 설계

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. 90도 벡터 시프트

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 스파이럴 베벨 기어 세트직선형 베벨 기어와 달리 나선형 기어는 톱니가 곡선 형태로 되어 있어 점진적으로 맞물립니다.

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

2. 토크 증폭 역학

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. 열평형

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 확장형 오일 섬프 그리고 방사형 핀 디자인.
