Head Wheel Gear in Stacker-Reclaimer

Head Wheel Gear Parts in Stackers and Reclaimers

The Head Wheel Gear is a critical component in the head wheel assembly of stackers and reclaimers, responsible for driving and guiding the conveyor belt or scraper chain. These parts are essential for the efficient operation of the equipment, ensuring smooth material handling during both stacking and reclaiming processes.

Technical Features and Specifications: Head Wheel Gear

• Material: High-strength steel or alloy materials are used to ensure durability and resistance to wear.
• Surface Treatment: Some gears are coated with wear-resistant materials to extend service life.
• Customization: Head Wheel Gears can be customized based on specific requirements, including pitch, diameter, and tooth profile.
• Integration with Drive Systems: The gears are designed to work seamlessly with hydraulic or electric drive systems, ensuring efficient power transmission.

Maintenance and Inspection: Head Wheel Gear

• Regular Lubrication: Proper lubrication is crucial to reduce friction and wear, extending the life of the gears.
• Inspection for Wear: Regular checks for signs of wear, such as tooth damage or excessive noise, are essential to prevent failures.
• Alignment Checks: Ensuring that the gears are properly aligned with the conveyor system helps maintain efficiency and reduces the risk of malfunctions.

Importance in Operation: Head Wheel Gear

• Efficient Material Handling: Smooth operation of the conveyor belt or scraper chain during stacking and reclaiming.
• Reduced Downtime: High-quality and well-maintained gears minimize the risk of breakdowns.
• Enhanced Safety: Reliable gear operation reduces the risk of accidents and improves overall safety.

Technical Features in Stacker-Reclaimer

The stacker reclaimer is an efficient and continuous loading and unloading machine, which is mainly used for loading and unloading iron ore, coal, sand and other materials in bulk yards of bulk cargo terminals, steel mills, large thermal power plants and mines. Stackers are widely used at home and abroad due to their high operating efficiency. Stackers are generally composed of four parts: a variable amplitude mechanism, a traveling mechanism, a bucket wheel mechanism and a slewing mechanism, which can complete the dual tasks of stacking and retrieving coal. According to different usage scenarios, stackers are divided into circular stockyard mixing stackers and bucket wheel stackers.

1.Equipment Introduction
The circular stacker-reclaimer is mainly composed of a stacker and a reclaimer. The stacker is mainly composed of a cantilever stacking belt conveyor, a center column slewing mechanism, a hydraulic luffing mechanism, etc.; the reclaimer is mainly composed of a bridge, a scraper conveying system, a material rake system, an end beam travel mechanism, and an electronic control system.

2. Advanced manufacturing process
Customized design: Our company only makes accessories for stackers, such as scrapers, head and tail sprocket devices, guide wheels, chains, travel devices, etc., and can go to the site to survey and draw drawings.

Manufacturing process: The scraper conveying system consists of: several hangers are hung under the bridge, and two chain guide grooves are set on the upper and lower parts of the hanger, and an anti-deflection guide groove is set in the middle of the upper part and the middle of the lower part.Shorten with AITwo conveying chains are installed in the upper and lower left and right chain guide grooves, and a broken line scraper is set between the two chains. The head is provided with a transmission sprocket and a driving device, and the tail is provided with a tensioning sprocket and a tensioning device.

The hanger is welded by I-beam and steel plate, and the upper part is connected to the bridge by bolts. The main function of the guide groove is to support the chain, and the chain is a non-standard large pitch sleeve roller conveyor chain. The roller runs on the track equipped with wear-resistant strips in the guide groove.

The sleeve roller chain pitch is 315mm, and a scraper is installed for two pitches. The scraper spacing is 500mm. The scraper is in a broken line shape. The flange on the scraper and the chain side ear are fixed with bolts. The main bolt of the scraper is a steel plate structure composed of Q235-A steel plate.

The driving part consists of a three-phase asynchronous motor, a hydraulic coupling, and a reducer. The scraper system drive is a chain transmission mechanism. The driving device is located at the head. Two driving sprockets are installed on the sprocket shaft to drive the chain to achieve the operation of the scraper.

The tail tensioning part adopts a composite spring buffer tensioning form, which includes a tail sprocket, a sprocket shaft, a tensioning bearing seat with a sliding track, a tensioning screw and a composite buffer spring. The tensioning of the chain is completed by adjusting the nut on the screw. The role of the buffer spring is that due to the small number of sprocket teeth and large pitch, the chain will produce periodic changes in the center distance of the sprocket when rotating, that is, pulse vibration occurs. The buffer spring can reduce this vibration and improve the stability of the chain movement.
Quality control: Strictly operate in accordance with the requirements of the 9001 quality management system.

3. Strict inspection
Each product is inspected before delivery, including material testing and physical performance testing to ensure functional performance.

Performance indicators

1. After the scraper and chain are installed, they should rotate flexibly. All bolt connection parts must be firm and reliable.
2. The site of use and the user must do a good job of pre-use training and safety training to avoid safety accidents.
3. The normal use of the scraper can reach 30,000 hours.

Application

It is suitable for mining, metallurgy, building materials, chemical industry, coal and other industries, and is used to transport materials of different particle sizes and different bulk densities.
