Abstract

Swing on the excavator is a usefull component to swing upperstructur unit by 360°. Swing device is divided into several components, among others: Swing motor, swing brake, and swing reducer. This analysis aims to determine the working mechanism of each component on the swing device and the magnitude of the forces that work. Swing motor is a component that converts pressure from main pump to mechanical movement, Swing brake functions to engage and disengage clucth and disk that serves to release cylinder block and lock cylinder block on swing motor, Swing reducer functions to reduce rotation of swing motor but increase torque, so swing device can swing upperstructur of excavator. The results of the analysis, the forces that work on swing motor like torque of 503,516 Nm obtained mechanical efficiency of 89,07 %, flow rate of 3,315 x〖10〗^(-3) m^3/minute, obtained volumetric efficiency of 79,30 %, and overall efficiency in motor swing equal to 71,13 %. Then the speed ratio and reduction of the swing reducer are 1.17 and -4,76 rpm at the first level and 1.05 and -3,85 rpm at the second level. Then there will be the amount of torque, tangential velocity, and nominal load on planetary gear swing reducer gear.
