Swing Gearbox Overload Protection Mechanisms

Introduction

The swing gearbox is an important component in the excavator’s hydraulic system. It is responsible for the rotation of the excavator’s upper structure. However, due to the harsh working conditions of the excavator, the swing gearbox is prone to overload, which can lead to serious consequences such as equipment damage and personnel injury. Therefore, it is necessary to install an overload protection mechanism in the swing gearbox to prevent such accidents.

Types of Overload Protection Mechanisms

1. Mechanical Overload Protection

Mechanical overload protection is the most common type of protection mechanism. It uses mechanical components such as springs and cams to limit the torque transmitted by the gearbox. When the torque exceeds the set limit, the mechanical components will be deformed or disengaged, disconnecting the power transmission and protecting the gearbox from overload.

2. Hydraulic Overload Protection

Hydraulic overload protection is a mechanism that uses hydraulic pressure to control the torque transmitted by the gearbox. When the torque exceeds the set limit, the hydraulic pressure will increase, causing the hydraulic components to operate and disconnecting the power transmission.

3. Electronic Overload Protection

Electronic overload protection is a modern protection mechanism that uses electronic sensors and control systems to monitor the torque and speed of the gearbox. When the torque exceeds the set limit, the control system will send a signal to the power transmission system to disconnect the power transmission and protect the gearbox from overload.

Signs of Swing Gearbox Overload

  • 1. Abnormal noise: When the swing gearbox is overloaded, abnormal noise will occur, which is caused by the abnormal friction between the gearbox components.
  • 2. Oil leakage: When the swing gearbox is overloaded, the oil pressure in the gearbox will increase, causing the oil seal to be damaged and oil leakage.
  • 3. Abnormal temperature rise: When the swing gearbox is overloaded, the temperature of the gearbox will rise abnormally, which is mainly caused by the increase in internal friction.
  • 4. Vibration: When the swing gearbox is overloaded, the gearbox parts will vibrate abnormally, which is mainly caused by the imbalance of the gearbox rotation.
  • 5. Slow rotation: When the swing gearbox is overloaded, the rotation speed of the gearbox will slow down, which is mainly caused by the increased torque and increased resistance.

Swing Gearbox Buying Guide

When purchasing a swing gearbox, it is important to consider the following parameters:

Parameter Description
1. Transmission ratio Determine the ratio of the output speed of the gearbox to the input speed of the gearbox.
2. Output torque Determine the maximum torque that the gearbox can output.
3. Input speed Determine the maximum input speed that the gearbox can handle.
4. Operating temperature Determine the temperature range within which the gearbox can operate normally.
5. Mounting position Determine the mounting position of the gearbox in the excavator’s hydraulic system.
