The working principle of the crankshaft pulley is to transfer the power of the crankshaft to other engine accessories through the transmission belt, such as water pump, generator and air conditioning compressor, so as to drive these parts to work normally. Specifically, the crankshaft pulley is connected to these parts by a transmission belt. When the engine is started, the crankshaft pulley begins to rotate, transfers power through the belt, drives a water pump to circulate water to cool the engine, drives a generator to charge batteries, and drives the air conditioning compressor to provide cooling functions
Advantages
Mitigate load impact : the belt pulley can absorb the impact of the engine during operation and protect related accessories from damage
stable operation, low noise, low vibration : pulley transmission structure is simple, small noise and vibration during operation
simple structure, convenient adjustment : pulley drive system is easy to adjust and maintain, the manufacturing and installation accuracy requirements are low
