Basic mechanical experiment （ Two ）
One 、 The experiment purpose
1. Through dynamic observation of the motion characteristics of the crank rocker mechanism , Make students understand the characteristics of quick return , And through an example, students can understand the application of this mechanism in engineering ;
2. Dynamic observation of the motion characteristics of the profiling turning mechanism through interactive operation , Make students understand the application of moving cam mechanism in engineering .
3. Dynamically observe the motion characteristics of the gearbox through interactive operation , Make students understand the characteristics of gear transmission and the meshing process of teeth , And through the disassembly of the gear box, students can understand the structural composition of the primary reducer .
4. Through interactive operation, students can dynamically observe the deceleration and shift modes of multi-level gearbox , So as to deepen students' understanding of the application of fixed axle gear train .
