Eickhoff SL300/SL750/SL900 Shearer Gears | Cutter/ Traction/ Transmission Gears

Description

Eickhoff Gear Product Overview This page provides a wide range of spare gears for Eickhoff’s classic SL300, SL750, and SL900 series coal mining machines. As the core of power transmission, the health of gears directly determines the equipment’s coal extraction efficiency and operational stability. Our gears cover cutting unit gearboxes, traction unit transmission boxes, rocker arm gears, and various drive shaft gears, all manufactured according to original factory drawings or higher standards, dedicated to helping you restore your equipment to its original design performance.

Product Series and Classification

Cutting Unit Gears: Includes cutting motor output shaft gears, idler gears, planetary mechanism sun gears, planetary gears, internal gear rings, etc., which withstand high torque impacts and require extremely high bending fatigue strength.

Traction Unit Gears: Includes traction motor gears, slip differential gears, travel wheel drive gears, etc., requiring high precision to ensure smooth traction speed.

Other Transmission Gears: Includes pump drive gears, auxiliary transmission gears, etc.

Technical Features and Advantages

Materials and Processes: Utilizing high-grade alloy carburizing steels such as 20CrMnTi and 18Cr2Ni4WA, and undergoing carbonitriding or deep carburizing heat treatment, ensuring high hardness (HRC58-62) on the tooth surface and high toughness in the core.

Precision Guarantee: Machined using high-precision CNC machine tools, gear precision reaches national standard grade 6 (GB/T 10095) or higher, ensuring smooth meshing, low noise, and high transmission efficiency.

Full Range Coverage: We not only provide commonly used gears, but also customize and supply a full range of gears based on your part numbers or drawings, including discontinued models.

Rapid Response: We maintain safety stock for commonly used models; for non-standard parts, we have a mature supply chain, enabling rapid production and delivery.

Application Scenarios and Fault Identification

When to Replace Gears:

The gearbox emits periodic abnormal impact sounds or sharp noises during equipment operation.

A large amount of metal debris or ferromagnetic particles are found in the oil.

Transmission failure, skipped teeth, or sudden equipment malfunction may occur.

During routine overhauls, inspection may reveal pitting, spalling, severe wear, or broken teeth on the tooth surfaces.

Quality and Service Commitment
We promise that all gears undergo dimensional accuracy testing, hardness testing, and magnetic particle inspection to ensure they are free of internal defects. We provide comprehensive technical support and can accurately match or measure and manufacture gears based on the part number, photos, or damage details you provide. We are your reliable gear transmission solution partner.
