Construction machinery engine components

Engine components in construction machinery, including pistons, rings, connecting rod bushings, crankshafts, and hydraulic pumps, are manufactured 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 wear-resistant coatings, nitriding, and hardening to ensure a service life exceeding 12,000 operating hours. Friction coefficients between contacting surfaces range from 0.08 to 0.12, and components can sustain instantaneous loads up to 2000 Nm.

In the design of construction machinery engine components, oil pathways and cooling channels are optimized to provide uniform lubrication and rapid heat dissipation. Components are engineered to resist vibrations, shocks, and thermal stresses, with thermal deformation under 0.05 millimeters. Weight varies from 0.2 to 35 kilograms depending on function, allowing direct installation on the engine block and chassis with standard bolts and shafts. Reliable operation is ensured within a temperature range of -20 to 300 degrees Celsius, maintaining optimal engine performance.
