一、叶轮工艺性分析YJ375系列液力变矩器叶轮材料系采用ZL 10铝合金,叶轮的结构特征见表1。由表1可以看出YJ375系列叶轮的形状具有如下特点: 1.循环园的形状近似于园形(内环、外环、中间流线),叶片在循环园内的装置为向心式涡轮、叶片的进、出口边为直线变化,叶轮之间的空腔较小(2～4毫米,见图1)。 First, the impeller technology analysis YJ375 series torque converter impeller material system uses ZL 10 aluminum alloy, impeller structural characteristics shown in Table 1. It can be seen from Table 1 that the shape of the YJ375 series impeller has the following characteristics: 1. The shape of the circular garden is similar to the circular shape (the inner ring, the outer ring and the middle streamline) The inlet and outlet edges of the blades vary linearly, and the cavity between the impellers is small (2 to 4 mm, see Figure 1).
