Sprocket Assembly in Scraper Conveyor
Sprocket Assembly in Scraper Conveyor
It plays a vital role in the scraper conveyor system. It consists of sprockets, shafts, bearings and other related parts. It is mainly used to drive the chain, which drives the scraper to move, thereby pushing the conveyed materials. The sprocket assembly ensures the power transmission of the scraper conveyor and the smooth conveying process.
Sprocket Assembly in Scraper Conveyor
Components
- Sprocket Body: Made from high-strength alloy steel and processed by precision milling to ensure accurate tooth profiles.
- Bearing and Shaft: The shaft is often heat-treated and quenched to enhance durability. It connects to the reducer via a spline.
- Seals and Lubrication System: The assembly includes oil seals and a centralized lubrication system to reduce wear and extend service life.
- Support Bearings: These are mounted on pedestals to support the shaft and ensure stable rotation.
Technical Features
- High Durability: The sprocket body undergoes heat treatment to increase strength and longevity.
- Precision Engineering: The assembly is designed to fit seamlessly with the scraper chain, ensuring smooth operation.
- Lubrication: The sprocket assembly features multiple oil injection ports for easy lubrication, which helps reduce friction and wear.
- Customization: Available in various sizes and materials to meet specific application requirements.
Maintenance and Installation
- Regular Lubrication: Ensure the sprocket assembly is well-lubricated to reduce wear and prevent overheating.
- Inspection: Regularly check for wear, especially on the sprocket teeth. If wear exceeds 6mm, the sprocket should be flipped or replaced.
- Installation: Remove rust and clean the spline before applying lubricant. Use the recommended lubricant (e.g., GB3141 heavy load industrial gear oil) for optimal performance.

Technical Features in Scraper Conveyor
Scraper is a continuous transport equipment that conveys bulk materials with the help of a moving scraper chain in a closed rectangular cross-section shell. Scraper is widely used in metallurgy, building materials, electricity, chemical industry, cement, ports, docks, coal, mining, grain and oil, food, feed and other industries and departments. It has a simple structure, good sealing, convenient installation and maintenance, flexible process layout, can convey granular and powdery materials horizontally, and can also be inclined within a certain angle range. Scraper is suitable for conveying various powdery, granular and block materials, such as coal, ore, cement, etc. The conveying distance can reach hundreds of meters or even thousands of meters, with a large conveying capacity, which can meet the needs of the production line. In addition, the height of the scraper is small, which is convenient for loading, the length is easy to adjust, and the body is strong. It is suitable for the working face of blasting and loading, so it is widely used in multi-town coal mines.
The advantages of scraper include that the transportation capacity is not affected by the size and humidity of the cargo, the structure is simple, the sealing is good, the installation and maintenance are convenient, the material can be conveyed horizontally or inclined, it can be used as a single machine or multiple machines can be used in combination, and it has strong adaptability. However, scraper conveyors also have some disadvantages, such as large working resistance, high power consumption, severe chute wear, easy chain breakage due to improper maintenance and use, and certain restrictions on transportation distance.
1. The main components of the scraper include the head, tail, middle trough and scraper chain. The head is the power part, which is composed of an electric motor, a reducer, a head frame, a sprocket assembly, a blind shaft and a chain tightening device. The tail is the tail device, including a tail frame, a tail roller, a tensioning device, etc., which are used to adjust the tightness of the scraper chain. The middle trough is the main working part, which is used to carry materials. The trough is welded with steel plates, and the inner wall is smooth to reduce resistance. The scraper chain is a key component, which consists of a scraper, a chain and a connector. It is made of high-strength alloy steel and has high tensile strength and wear resistance.
2. Advanced manufacturing process
Customized design: Our company can provide drawings and customized designs.
Manufacturing process: The material in contact with the material is Q235-A, scraper chain: chain rod material: 20 CrMnTi, carburized and quenched, HRC55-62; pin shaft: 20 CrMnTi, carburized and quenched, HRC55-62; scraper material: Q235-A, thickness 12mm;
Head and tail: packing seal.
Head shaft and tail shaft: 45#, quenched and tempered, HB220-300;
Head wheel and tail wheel: ZG45, quenched, HRC45-55;
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. All head shafts, tail shafts, scrapers, and drive devices should rotate flexibly after installation. All bolt connection parts must be firm and reliable. Before the newly installed conveyor is officially put into use, it should be tested for 2 hours of no-load and 8 hours of load.
2. The site and users must be trained before use and safety training to avoid safety accidents.
3. The normal use of the supporting wheel and chain plate can reach 30,000 hours, and the life of the frame part can reach 10 years.
Application
The scraper is widely used in metallurgy, building materials, electricity, chemical industry, cement, ports, docks, coal, mining, grain and oil, food, feed and other industries and departments.
