Item 2 Draw thepulley group part drawing and assembly drawing
Under theleadership of the teacher, read the figure 2.1 The assembly sketch of thepulley group (incomplete assembly diagram), and clarify the working principle,assembly relationship, and the coordination relationship (tightness). Draw thepart diagram of each non-standard part (express the structure shape, size,necessary technical requirements (such as size tolerance, surface roughness,here involves the coordination and accuracy level, material, need to check thetable using the manual)), and draw the pulley group assembly diagram.
