COOLING FAN PULLEY OF A HYDRAULIC DEVICE FOR A LOG COLLECTOR, A WOOD CRUSHER, A WOOD CHIPPER, AND A FERTILIZER SPREADER TO EFFECTIVELY PREVENT THE OVERHEATING OF A HYDRAULIC DEVICE WITHOUT A SEPARATE COOLER

摘要

PURPOSE: A cooling fan pulley of a hydraulic device for a log collector, a wood crusher, a wood chipper, and a fertilizer spreader is provided to implement the function of a cooling device as well as the function of a power transmission pulley.;CONSTITUTION: A cooling fan pulley of a hydraulic device for a log collector, a wood crusher, a wood chipper, and a fertilizer spreader comprises a rotating pulley(1) and support arms(2) which are installed between the central shaft(1a) and the pulley wheel(1b) of the rotating pulley. The central shaft of the rotating pulley is inserted to the drive shaft of a hydraulic machine using a hydraulic device. Each support arm comprises a blade type support arm(2a) with a specific angle. As the pulley rotates, air flow is created by the support arms and the hydraulic machine can be cooled.;COPYRIGHT KIPO 2012
