1.BW 250及BW 251船用减速齿轮装置 1.1 齿轮装置参数本减速齿轮适用于工作船舶连续工作时功率-转速比为P/n=0.308千瓦/分~(-1)(0,419马力/分~(-1))的工况条件。此比值在断续工况下,例如在快速巡逻艇或游艇等船舶上,可提高到P/n=0.432千瓦/分~(-1)(0.587马力/分~(-1)。只要不超过最大容许转速2500转/分,在给定的负载极限范围内,本齿轮装置适用于一切原动机。在BW 250结构中,齿轮速比为1.3～3.5。在具有较大轴向间距的BW 251结构中,速比最大可达6.0,因此它能满足1.3～6.0的速比。必须强调,这种新型减速齿轮箱不但结构
1.BW 250 and BW 251 Marine Gear Reduction Gear Units 1.1 Gear Unit Parameters This gear reduction gear is suitable for continuous operation of work vessels with a power / speed ratio of P / n = 0.308 kW / min ~ (0,419 hp / min ~ -1)) of the working conditions. This ratio can be increased to P / n = 0.432 kW / min -1 (0.587 hp / min -1) under intermittent operating conditions, such as for fast patrol boats or yachts. Maximum permissible speed 2500 rpm The gear unit is suitable for all prime movers for a given load limit In the BW 250 construction the gear ratio is between 1.3 and 3.5 In the case of BW 251 with a larger axial spacing Structure, the maximum speed up to 6.0, so it can meet the 1.3 ~ 6.0 ratio must be emphasized that this new type of reduction gear box not only structure
