Crankshaft Normally, all the journal faces of the crankshaft are transferred to the rounded corners for shot blasting/shot peening. These include bearing journals and crank pins. The crank pin bearing fillet is where stress is concentrated and the maximum stress occurs at the bottom of the crank pin transition fillet because the crank pin is at the top dead center when the engine is ignited. The stress analysis determines that the crank pin transition fillet is often the crack initiation site and extends to the main adjacent main bearing fillet until the destructive fracture of the entire crankshaft fails. A large number of tests have proved that whether it is forged medium carbon steel crankshaft, cast steel crankshaft or ductile iron crankshaft or aobei ductile iron crankshaft, shot blasting/shot peening is an effective method to improve the fatigue resistance and safe service life of the workpiece. Diesel engine crankshaft - The crankshaft is an important part of the diesel engine. It is required to test the fatigue performance of the crankshaft both during the product development phase and during the production inspection phase. During the actual operation of the engine, the load on the crankshaft is mainly the bending/torsion composite load. The bending fatigue failure is the most common form of crankshaft failure, and the torsional fatigue occurs when the engine output is large and the crankshaft is subjected to large torque. Destruction is the main form of failure. A fatigue comparison test was performed on a crankshaft test piece of a diesel engine, and the material was Armco 17-10 Ph stainless steel. The test results show that the unreinforced crankshaft and shot blasting/shot peening crankshaft have a measured fatigue strength of 43 ksi (293 MPa) and 56 ksi after 1 billion cycles of alternating stress loading. 386 MPa), which indicates that the fatigue strength of the diesel crankshaft is increased by about 30% after shot blasting/shot peening.

What kind of plastic is used in faucet? ABS engineering plastic is commonly used for faucet levers due to its excellent resistance to high and low temperatures. Are all faucets made of plastic? Faucet Handles, the part you see most often is the faucet handle. This part is made of metal on most single-handle bathroom, shower and Kitchen Faucets. On double-handle bathroom faucets with round knobs, the handles are plastic. These decorative handles are easy to spot because they are clear and have a decorative cut.
