Connecting Rod

Connecting Rod

One end of connecting rod is connected to piston through a pin called gudgeon pin (at smaller end) and crank pin at bigger end the of the connecting rod. Connecting rod connects crank shaft and piston. The assembly is made out of connecting rod and crank pin with are manufactured out of low carbon alloy steals like SAE 8620. They are subjected to heat treatment process like carborizing hardening and tempering process. The heat treatment process is carried out in modern gas carborizing furnace in which carbon potential is controlled with the help of obey-probe system, having zirconisum sensor. The probe is working in conjuction with M.V. controller to have maximum accuracy of carbon potential on the component.

Honing

The roughness of inner hole surfaxe is lower than Ra0.2 with a cross pattern. This ensures proper lubrication in the inside diameter and reduces the friction between connecting and bearing. We use the most advanced automatic chamber there are there for the heat treatment process. This not only guarantees, but also ensures the cementite thickness, which do improve the useful life time of a connecting rod.

Honing

Crank pin

  • The roughness of surface is lower than Ra 0.1 and Reduces the friction between crank pin and bearing.
  • The angle is smooth and without an edge. It ensures the crank pin doesn’t damage the crankcase during assembly.
