Introduction

Modern mechanical engineering is impossible to imagine without metal cutting machines. Machines are the basis of all mechanical engineering, they perform most of all possible operations. The range of machines currently in existence is huge, machines are used from the simplest drilling machines that can process the workpiece in only one direction to the most modern processing centers that can process the workpiece in any direction and any position.

One of the most common and relatively inexpensive machines of our time is the milling group. The machine described in this work is representative of horizontal milling machines, which is universal. This machine allows to process external simple and shaped surfaces, cut straight and screw grooves.

The purpose of this course project is to acquire and consolidate the acquired knowledge in the design work. All this is carried out on the basis of the design of the drive of the main movement of the machine. As a result, you need to get a correctly designed set of design documentation containing drawings of the developed drive, specifications, calculation of parameters necessary for the development of the drive.

Conclusion

In operation, the drive of the main movement of the vertical-milling machine 1A616 was designed with 16 rotation speeds. The number of teeth and modules of group gears was calculated, and the parameters of V-belt gear were also calculated. A spindle assembly, a pinion chain was also designed and the design of the gearshift mechanism was chosen. All parameters were calculated and tested on the computer using the "Desing" program. Thus, it can be said that since all the obtained parameters satisfy the specified conditions, it can be proposed to use this drive of the main movement in practice.
