Rod steel bar and hard as to how to cast or forged can be built Cross-beam connecting rods for resistance as I can be .Its connecting rods and pistons to the crankshaft established The resulting impact of fuel force the piston pushes the Transferred onto the crank and crank down, and Finally, reciprocating motion of the piston to the crankshaft, connecting rod is inserted by the The crankshaft is converted into rotational motion.
In an era of high pressure high tensile forces to the connecting rod is inserted so have made it very desirable and possible light. Large part by the connecting rod bearing caps to the hardware is mounted on a crank shaft and a connecting rod and crankshaft bearings placed between two halves of the small end of the connecting rod and the piston pin is connected by Gzhn .dakhl location of the Gzhnpyn of a Bush used to reduce friction and lubrication is performed by connecting rod is used in two ways:
1. In some duct through the connecting rods and engine oil from the bearing hole and the Bush Gzhnpyn it.
2. Some other engines spraying oil holes on one side and the connecting rod The lubrication of the cylinder wall When crankshaft rotation when the crankshaft and connecting rod hole in a fall along Oil passing through the crankshaft and connecting rods, and Connecting rod side of the cylinder wall hole is sprayed Oil grooves and holes in the cylinder wall and piston with rings into the oil and The Bush Gzhnpyn down and it is lubricated.
Moving the connecting rod bearings are divided into two categories:
Bearing a cloth:
In this part of seamlessly connecting rods made large Inside the small rollers or bearings are usually placed This type of bearing more petrol and two-stroke engines used in certain small engines.
Bearing two pieces:
In this type of large parts of the connecting rod is divided into two semi-circular shape (A semicircle of low hills form)After putting both parts in animated throat crankshaft connected to each other by bolts.
V-rod engines (v) the
The form of the connecting rod on V engines on three types:
Parallel connecting rods:
In this type of engine, two piston rods of the two next to each other and are closing in on a neck crank, connecting rod, such as rod building typical of this type.
Rod Cross (Cross):
In this type of connecting rod bearings as well as previous animated both connecting rods of the two cylinders are placed on a neck crankThe difference is that (the pan to form two branches of the connecting rod and the other end of the connecting rod is narrow)As a result, the end of a connecting rod connecting rods inside the other, and then both sides of the crankshaft are closed.
The connecting rod hinged:
In this type of throat crankshaft connecting rods in the rod is connected, and that the leaders of a hole and a pin to the top of the pan by moving the saddle valve connects the first connecting rod.
The disadvantage of connecting rods:
Rarely happens that Connecting rods need to be replaced unless Enter the result of an accident or severe damage to the connecting rod The ongoing work of engine connecting rod is tilted or swung picks In general Gzhnpyn parallel axis gear crank and crank the engine must be to ensure an New rod or worked before closing the engine of curvature (shimmy)The complexity of the trial If the connecting rod is bent because Gzhnpyn axis parallel to the axis of the crankshaft is not lame The lateral force applied to the crankshaft and bearings inappropriate animated as well Gzhn PIN is entered.
