Final Drive Travel Gearbox Fit for Excavator SANY SY135

Final Drive Travel Gearbox Fit for Excavator SANY SY135

Introduction

Travel gearbox (final drive) is an important component in excavators that is responsible for transmitting torque to the tracks and driving the machine forward or backward. It serves as the final stage of the powertrain, providing the necessary speed reduction and torque amplification to the hydraulic motors that drive the tracks.

Installation and Functionality

The travel gearbox is installed in the undercarriage of the excavator, connected to the hydraulic motor through a flange coupling. Its function is to reduce the high rotational speed of the hydraulic motor and increase the torque output, which is then transferred to the final drive sprocket and tracks through the driving gear and pinion gear. The gearbox consists of several gears and bearings that work together to achieve the desired speed and torque output.

Core Features and Advantages

• High-precision manufacturing process using advanced CNC equipment, ensuring high dimensional accuracy and low noise.
• Optimized gear design and tooth profile, providing maximum torque output and durability.
• High-quality materials used for all components, including gears, bearings, and seals, ensuring long service life.
• Reliable and efficient lubrication system that ensures smooth operation and reduces wear on the components.
• Thorough testing and quality control procedures, ensuring that every unit meets or exceeds the OEM standards.

Compatibility and Performance Parameters

Our travel gearbox is specifically designed for the SANY SY135 excavator, and it is tailored to meet the performance requirements of this machine, including the load capacity, torque output, and speed matching. The gearbox is fully compatible with the original equipment and can be installed without any modifications.

Parameters for Purchase

Signs of Wear and Tear

• Unusual noises or vibrations coming from the gearbox.
• Difficulty in changing gears or engaging the travel mode.
• Reduced travel speed or torque output.
• Visible signs of damage or wear on the gears or bearings.

Maintenance Tips

• Check the oil level and quality regularly and replace it as needed.
• Inspect the gears and bearings for signs of wear or damage and replace them as needed.
• Clean the exterior of the gearbox regularly to prevent debris from entering the interior.
• Ensure that the bolts and fasteners are properly tightened and torqued.
• Follow the manufacturer's recommended maintenance schedule and procedures.

Installation Guidelines

Installation of the travel gearbox should be performed by a qualified technician with experience in excavator maintenance. The following steps should be followed:

1. Remove the old gearbox and inspect the flange coupling and mounting bolts for wear or damage.
2. Clean the mounting surface and apply a thin layer of oil or grease.
3. Install the new gearbox and secure it with the mounting bolts, torquing them to the manufacturer's specifications.
4. Connect the flange coupling to the hydraulic motor and torque it to the recommended value.
5. Fill the gearbox with the recommended oil and check the level.
6. Start the engine and test the operation of the travel gearbox in all gears and modes.
