It will be completed in 2 weeks (totally 10 working days). The course will be completed at a concentrated time
22、and place The progress can be arranged under the guidance of the teacher according to the following.First day: Design mobilization and preparation. Complete prime mover selection, total transmission ratio allocation, and parameter allocation at all levels.Second day: Design of transmission parts, in
23、cluding design of belt transmission (or chain transmission) and gear transmission of all levels.Third day to fifth day sixth day: Design calculation and verification of shafts, design of bearings and their components, drawing sketches of assembly drawings.Sixth day to eventh day: Select the key conn
24、ection and coupling. Check calculation, lubrication and accessory design. Complete the assembly drawing.Eighth day to ninth day: day: Complete the drawing of two parts drawings.Tenth day: Complete the preparation and submission of design specifications; reply.IV、Notes1. Students should independently
25、 complete design tasks under the guidance of teachers2. The completed drawings should be completed without error in design, good quality of the drawing, reasonable and clear layout, neat and in full compliance with national standards.Course Exercise in Mechanical Design is carried out independently
26、by students under the guidance of teachers. Each student should clearly design tasks and requirements, and draw up a design plan to master the design progress. In order to ensure the design quality and complete the design tasks in order, the design should be carried out in stages, the design of each
27、 stage must becarefully checked, and the next stage of design can be continued only when there is no principle error. In the design process, students must think independently, delve deeper, and actively and creatively design. The course contrasts with copying and perfunctory responsibility, tolerati
28、ng errors or relying on teachers. The design attitude is required to be serious and correct. Only in this way can the basic requirements of teaching be met, and students can be well trained in design ideas, design methods, and design skills.V、Assessment and Achievement Evaluation in PracticeCourseOb
