Function of the connecting rod 's weight
The lighter the connecting rod and piston, the greater the resulting in power and the lesser the vibration because the reciprocating weight is less.
The connecting rod carries the power thrust from piston to the crankpin and hence it must be very strong, rigid and also as light as possible.
Bush and bearing:
Bush and bearing are installed at both ends of the connecting road. The phosphor bronze bush is placed near the small end of the rod and the piston pin is connected with the smallest end piston.
The big end stays connected with the crank and the big end of the rod is divided into two half which we can easily mount above the crank bearing shell.
And then after connecting the rod with the crank in the last, both sides of the big end are joined with the help of nuts and bolts. So by combining all these we prepare the connecting rod.
In splash lubrication, a sprout is placed at an angle, so that whenever the rod is down, the sprout is inserted into the lubricating oil.
So that the lubricating oil reaches the end of the bearings through the sprout. So when this rod goes up, the sprout causes the oil to splash, so we call it to splash lubrication.
In pressure lubrication, the end of the connecting rod has a hole near the bearing, And there the oil pressure is sent for lubrication which we call pressure lubrication.
Connecting rod Types:
This mainly of two types depending on the structure
Single piece and Two pieces or split piece of connecting rod
Single piece connecting rod:
The big end of a single rod is made in one part instead of two. A needle bearing is fitted in it
Two-piece or split piece of connecting rod:
This type of connecting rod in which consists big end is made up of 2 pieces
