摘要
山地果园履带运输机采用轮毂电机作为动力源,通过链传动方式来减速增矩,为计算该主减速比,设计了一款台架,用于获得电机的机械特性曲线模型。将试验数据通过SPSS软件处理,得到电机的机械特性曲线,并得到电机的外特性曲线模型为n=446.835-3.848T,然后根据设计指标计算履带运输机在极限工况下所需功率为0.868k W。再根据无刷直流电机的调速及输出功率特性,求得在该功率输出下,电机对应的转速为179 r/min。又已知驱动轮的设计转速为9 6 r/min,从而求得主减速比为1.8 6。本试验研究可为设计山地果园履带运输机提供指导。
Because of hub motors were used as the power source of the mountainous orchard crawler transporter and in- creased the torque by chain, to calculate the main reduction radio, a bench was designed to obtain the mechanical char- acteristics of the motors. The mechanical characteristic curves of the motor was obtained by the SPSS software, and the model of the external characteristic curve of the motor was n=446. 835-3. 848T. According to the design index, the required power of the crawler transporter under extreme condition is 0. 868kW. At this power output, the corresponding ro- tational of the motor was 179 r/min, according to the speed and output power characteristics of Brushless DC Motor. The main reduction radio was 1.86 when the design speed of the driving wheel was 96 r/min. The study can provide reference for the design of mountainous crawler transporter.
