Turkey 185 connecting rod

The connecting rod is used to connect the piston and the crankshaft, and transmit the force exerted by the piston to the crankshaft, and convert the reciprocating motion of the piston into the rotational motion of the crankshaft.

The connecting rod body is composed of three parts. The part connected with the piston pin is called the small end of the connecting rod; the part connected with the crankshaft is called the big end of the connecting rod, and the rod connecting the small end and the big end is called the connecting rod shaft.

The small end of the connecting rod is mostly a thin-walled circular structure. In order to reduce the wear between the piston pin and the piston pin, a thin-walled bronze bushing is pressed into the small end hole. Drill or milled grooves in the small head and bushing to allow splashed oil to enter the mating surface of the lubricating bushing and piston pin.

The connecting rod shaft is a long rod, and the force is also large during work. In order to prevent its bending and deformation, the shaft must have sufficient rigidity. For this reason, most of the connecting rod shafts of vehicle engines adopt an I-shaped section. The I-shaped section can minimize the quality with sufficient rigidity and strength. Some highly enhanced engines adopt an H-shaped section. Some engines use the small end of the connecting rod to spray oil to cool the piston, and a hole must be drilled longitudinally in the shaft. In order to avoid stress concentration, the connection between the connecting rod shaft and the small end and the big end adopts large arc smooth transition.

In order to reduce the vibration of the engine, the mass difference of the connecting rods of each cylinder must be limited to a minimum. When the engine is assembled in the factory, it is generally divided into groups according to the mass of the large and small ends of the connecting rods in grams. The same group of connecting rods is selected for the same engine.

On the V-type engine, the corresponding cylinders in the left and right rows share a crank pin, and the connecting rods have three types: parallel connecting rods, fork connecting rods and main and auxiliary connecting rods.

The company mainly produces crankshaft, connecting rod, cylinder liner, heat exchanger four series of diesel engine supporting products, and TMR preparation machine and other series of animal husbandry machinery products. It is the key supporting unit of China Development Group Corporation of the Ministry of Agriculture, Zibo Diesel Engine Corporation, Zichai Qingdao Boyang Diesel Engine Co., Ltd., and Zibo New Energy Co., Ltd. The company is divided into four workshops, a total of more than 230 sets of equipment, special aircraft, etc., the company also has a physical and chemical laboratory, equipped with various types of test equipment, with mechanical processing, riveting, heat treatment, nitriding, flaw detection, electrostatic spraying, Physical and chemical inspection as one of the comprehensive production capacity. It has the annual production of 3000 crankshafts of various types of marine diesel engines. 30000 connecting rods; 2000 cylinder liners; 4000 sets (pieces) of various intake pipes and coolers; The production capacity of more than 600 sets of various animal husbandry machinery.
