Swing Gearbox Fit for Excavator Yuchai YC85-6

Introduction

Swing gearbox, also known as the swing drive, is an essential component in the hydraulic excavator. It functions as a power transmission device that enables the machine to rotate on its chassis or turn around while digging. The swing gearbox has the following functions:

• Transmits power from the hydraulic motor to the excavator's upper structure.
• Controls the excavator's swing speed and direction.
• Supports the weight of the upper structure.

Our swing gearbox is designed to fit the Excavator Yuchai YC85-6 model perfectly.

Installation and Working Principle

The swing gearbox is mounted on the upper structure of the excavator, and it drives the excavator's rotation via the swing pinion. The working principle of the swing gearbox is based on the hydraulic motor and the planetary gear system. The hydraulic motor generates torque, which is then transmitted to the planetary gear system. The planetary gear system multiplies the torque and delivers it to the swing pinion. As a result, the excavator's upper structure rotates smoothly and efficiently.
