Introduction of engine crankshaft pulley ：
The role of engine crankshaft pulley is to drive the operation of engine accessories such as water pumps, generators, and air-conditioning pumps. Crank pulley transmits the power of the crankshaft to other components through the transmission belt to make crank pulley work normally.
The principle of the pulley is to transfer power to other components, such as generators, water pumps, booster pumps, compressors, etc., through the engine crankshaft pulley to achieve the normal operation of the engine.
The advantages of this pulley we manufacture are smooth transmission, low noise, low vibration, simple structure and easy adjustment. Compared with meshing transmission, the manufacturing and installation accuracy requirements of pulley transmission are low, and it has overload protection function. In addition, the two-axis center distance adjustment range of our engine crankshaft pulley's pulley drive is large.
The advantages of our production of crankshaft pulley ：
Manufactured from high-strength steel, the outer pulley rim provides exceptional rigidity and wear resistance. It withstands long-term frictional abrasion and tensile stress exerted by the multi-ribbed belt, maintaining dimensional stability and ensuring uninterrupted, stable rotational power transmission from the crankshaft to engine auxiliary components.
The intermediate elastic damping layer is compounded with Butyl Rubber and synthetic rubber, featuring superior damping capacity and anti-fatigue properties. It effectively absorbs crankshaft torsional vibrations generated during engine operation and blocks high-frequency vibrations from propagating to the belt drive system, reducing fatigue damage to accessories and suppressing abnormal drive noise.
The inner hub core (crankshaft mating interface) is precision-machined from 1045 medium carbon steel (No. 45 steel) with surface quenching hardening. It offers outstanding mechanical strength and ultra-high concentricity, establishing a firm, zero-backlash connection with the crankshaft to guarantee synchronous rotation and consistent transmission precision.
4.Configurable Auxiliary Designs for Versatile Application DemandsHigh-performance variants integrate an embedded steel constraining layer within the damping rubber, further boosting vibration damping efficiency and dynamic stability. For lightweight-focused applications, the outer pulley rim is fabricated from aluminum alloy, balancing structural strength and weight reduction to support the vehicle’s overall lightweighting strategy.
