本文介绍了一种新的东风型机车风扇用偶合器变速箱,它可取代东风型机车现用的后变速箱。该变速箱具有下列优点:能根据柴油机冷却水温的变化自动调节风扇输出功率,并且冷却水平均温度提高了,水温变化范围也小,节油;司机操作简化了;改善传动零件工作条件,延长零部件使用寿命;有功率储备,为缓和东风型机车冷却能力不足问题提供了条件。
This paper introduces a new type of Dongfeng locomotive fan coupling gearbox that can replace the existing rear-end gearbox of Dongfeng locomotive. The transmission has the following advantages: According to the diesel engine cooling water temperature changes automatically adjust the fan output power, and the average cooling water temperature is increased, the water temperature range is small, fuel-efficient; driver simplifies operation; improve transmission parts working conditions, extend the zero Parts life; power reserves, in order to ease the lack of cooling capacity of Dongfeng locomotive provided the conditions.
