Introduction

Any machine consists of parts that can be both simple (nut, key) and complex (crankshaft, gearbox housing, machine bed). Parts are assembled into assemblies (rolling bearings, couplings, etc.) - completed assembly units consisting of a number of parts that have a common functional purpose.

Machine parts are the first of the design courses in which they study the basics of machine and mechanism design. It is in this discipline that the first course project is carried out, requiring the student to know not a separate discipline, but a number of disciplines in the complex. When performing this project, the student uses material studied in such disciplines as copromat, materials science, theoretical mechanics, etc. The course on machine details is the first inherently creative work of the student .

The main goal of the course project on machine parts is to acquire student design skills. Working on the project, the student performs calculations, learns the rational choice of materials and shapes of parts, strives to ensure their high economy, reliability and durability. The experience acquired by the student is the basis for his course projects in special disciplines and for graduate design, as well as all further design work.
