Features: This book is a national planned teaching material for secondary vocational education, written according to the "Teaching Syllabus for Mechanical Basics in Secondary Vocational Schools (Trial)" issued by the Ministry of Education in August 2000. The main content includes an overview of mechanical basics, planar link mechanisms, cam mechanisms, intermittent motion mechanisms, gear drives, gear trains and reducers, belt drives and chain drives, bearings, connections, and hydraulic transmission. This textbook involves relatively little calculation and focuses on strengthening the content of parts applications, installation, and fixing methods. It introduces practical examples of mechanism applications, adds training guidance and innovation awareness cultivation, and aims to train students' ability to solve practical production problems. This book can be used as a teaching material for engineering technology-related majors in secondary vocational schools, as well as a training textbook and reference for technical personnel, management personnel, and technical workers.
