Week 19

Title : Bearing

Objectives : to choose the suitable bearing to be used in my prototype

Contents : this is the most difficult part to be completed.. i need to find the bearing that smooth enough to hold the turbine, so that it can turns at low wind blow.. i had spent an amount of money which had same value as one KFC snack plate, to buy a pair of skateboard bearing.. but i had make a mistake.. the bearings are too small to be put on the rod of my turbine.. when the bearing cannot be done, i got stress for a while, thinking about the bearing.. then i decided to go back to the welding shop to ask about the bearing whether they have it or not, and if they do not have it, maybe they know where i can buy it.. i had my luck on that day, the welding shop had the bearing that i wanted.. he proposed me cradle bearing, which is more bigger than the skateboard bearing.. and the bearing is smooth, i like it..
 
Results :
the bearing got many sizes and smoothness.. i decided to choose the smoothest one.. i will welding the bearing on the top of my rod to hold the turbine.. but what worried me mostly is can the turbine rotate with this bearing.. i need to finish my prototype completely for me to test my turbine..


Conclusion : i hope that with the choose of the cradle bearing, i had made a right choice in my life.. hopefully, the bearing can function as i wanted it to..
