Construction machinery engine components

Engine components in construction machinery, including pistons, rings, connecting rod bushings, crankshafts, and hydraulic pumps, are made from alloy steel and high-strength aluminum to withstand cylinder pressures up to 25 MPa and operating temperatures up to 300 degrees Celsius. Dimensions and tolerances are CNC-controlled, with surface finishing precision up to 0.01 millimeters. Contact surfaces are reinforced with nitriding, hardening, and wear-resistant coatings to ensure a service life exceeding 12,000 operating hours. Friction coefficients range from 0.08 to 0.12, and components can endure instantaneous loads up to 2000 Nm.

Oil pathways and cooling channels are optimized to provide uniform lubrication and efficient heat dissipation. Components are engineered to resist vibrations, shocks, and thermal stresses, with thermal deformation below 0.05 millimeters. Component weight varies between 0.2 to 35 kilograms depending on application, and installation is direct on the chassis and engine block using standard bolts and shafts. Reliable operation is guaranteed within a temperature range of -20 to 300 degrees Celsius, maintaining optimal engine performance.
