Introduction

The development of mechanical engineering has led to an increase in the requirements for reliability, durability, repairability of units and assemblies. The more complex the assembly in design, the more labor-intensive it is in manufacture, accordingly, its cost will be higher.

The purpose of this course project is to change the design of the node in such a way as to increase its efficiency.

The course design provides for the calculation of the designed assembly and the graphic part, in which the assembly drawing of the assembly and the working drawings of the parts included in it are reflected.

Analysis of the existing structures of the main gears made it possible to stop at the main transmission of the ZIL431410 truck.
