Introduction

The course project on machine details is one of the first independent engineering works of the student, completing the general education cycle. The project uses knowledge gained in the study of such disciplines as theoretical mechanics, resistance and materials, mechanical engineering technology, etc.

The design objects are drives of various stationary agricultural machines: conveyors, mixers and feed distributors, machines for cleaning and washing parts, etc. The drives widely use parts and devices of general industrial purpose: mechanical gears, couplings, bearings, shafts, fasteners.

In agricultural production, it is sometimes necessary to manufacture simple mechanisms on their own.

The electric motor is selected according to the required power and estimated rotation speed. Worm gears are designed according to the criterion of contact strength of the active surface of teeth, checked by contact and bending stresses.

The estimated calculation of shafts is carried out for net torsion at reduced permissible stresses. We choose bearings by the nature of the load on the shafts and by the diameters of the shafts, we check for durability by dynamic load carrying capacity. Key connections are checked for crushing.

The lubrication method and oil level are due to the arrangement of the mechanism. compactness;

Advantages:

smoothness and noiselessness;

relatively small weight of the structure;

reliability and ease of care
