Gear Cross Rods

The connecting rod connects the piston to the crank or crankshaft. It enables to convert the reciprocating motion of the piston into the rotary motion of the crankshaft.

Materials used to make Connecting Rods
The gear cross rods or connecting rods are under a lot of pressure. The materials used to make them should be strong enough to withstand the pressure. Some of the most commonly used materials for making connecting rods are:

• Alloy Steel
• Aluminum
• Titanium
• Cast iron

Characteristics of Connecting Rods

• Connecting Rods should be light but at the same time strong enough to transmit the thrust of the pistons to the crankshaft.
• They have two holes for connecting the piston pins and crankshaft.
• The holes of the connecting rods for the purpose of accurate fittings of the bearings should be parallel.

Maintenance of connecting Rods
The connecting rod bearings are under a lot of stress from the force produced by the pistons. So, they should be lubricated properly to avoid untimely wear.
