#automatic drain cleaner

This paper describes about the design and fabrication of automatic drain cleaner. There are a large number of machines used for removing out the wastes from drains. Nowadays, automation plays a vital role in all industrial applications. The automatic drain cleaner can be used in domestic, industry, large plants, irrigation and drainage cleaning system. In order to overcome the problems in manual drain cleaning, Automatic Drain Cleaning System is implemented to clean and control the drainage level. Every automatic drain cleaner has four main components, namely DC motor, 12 V battery, chain drives and shafts. The rotational speed of the drive shaft is 26 rpm. But in this paper, only shaft design is calculated. The required power from a motor to drive this shaft is 60 W. In designing shaft, chain tension, sprocket load and bearing load are taken into account and also bending moment and torque are included.
