Coal Mine Scraper Gearbox

Advantage of advanced platform and modularization: Relying on the advanced platform system, JS series scraper gearbox adopts modularization design concept. This design allows excellent interchangeability of parts, which is a great advantage in the process of equipment maintenance and repair.

Excellent gear shape optimization technology: The unique gear shaping technology is used to accurately shape the tooth profile and tooth direction of the gears. When the gears are meshing, the contact state can be significantly improved, so that the load is evenly distributed, effectively reducing the shock and vibration in the meshing process.

Multiple sealing protection mechanism: Equipped with various sealing forms and special sealing structure, it can deal with the complex and harsh working conditions underground in an all-round way.

Highlights of large inclination design: The special large inclination design is a major feature of this series of gearboxes. In the underground coal mine scraper conveyor, scraper transfer machine and other application scenarios, the large inclination angle design can enable the host to adapt to a greater angle of inclination when conveying materials to reduce the occurrence of material slippage and improve the efficiency and continuity of material conveying, which can help to optimize the entire process of coal mining operations, improve the overall efficiency of coal mine production, and provide strong support for the efficient mining of coal mines.

 

flexible Speed Ratio Adjustment: The range of speed ratio is set between 3.5 - 40, which can be flexibly selected according to the specific operational requirements of scraper and transfer machine under different working conditions, such as conveying distance, conveying speed, material characteristics and other factors.

Wide Power Coverage: The power range is from 40 - 1,600 (kW), which makes it suitable for various sizes of scrapers and scraper transfer machines with different production capacities in underground coal mines.

 

Mainly used in coal mine scraper and transfer machine and other equipment. In the process of coal mining, scraper machine plays a crucial role, it is responsible for coal mining machine mining down the coal along the scraper chain from the working face to the transfer machine, to realize the initial transfer of coal. JS series scraper gearbox, as the core transmission parts of these two types of equipment, ensures the stable and efficient operation of the scraper and the transfer machine by virtue of its excellent performance, and is an indispensable key equipment for the smooth mining and transportation of coal in the comprehensive mining face of the coal mine. It is an indispensable key equipment to realize the smooth mining and transportation of coal in the comprehensive mining face under the coal mine.

 

Before installation, make sure to conduct a detailed investigation of the underground installation site to ensure that the installation foundation is firm, level, and meets the installation requirements of the gear box. The model and specification of the gear box should be checked carefully for its suitability with the scraper and the transfer machine, and the operation should be carried out in strict accordance with the installation instructions to ensure that all the connecting parts are accurately installed and reliably fastened, so as to prevent the equipment from vibration, offset and other abnormalities during operation due to improper installation and affect the performance and service life of the equipment.

Before the first operation, it is necessary to carry out a comprehensive cleaning of the gear box interior, check the installation of the gears, bearings, shaft seals and other key components as well as the lubrication status, and fill high-quality lubricating oil in accordance with the specified oil level and oil requirements.

In the process of operation, establish a perfect monitoring mechanism for the operation of the equipment, regularly test and record the oil temperature, oil pressure, vibration, noise and other key parameters of the gear box, and at the same time, pay attention to the material conveying situation of the scraper and the transfer machine, the degree of wear of the chain, and the wear and tear of the chute.

For the long-term out of service or seasonal out of service equipment, before decommissioning should do a good job of equipment cleaning, anticorrosion, rust treatment, the gear box lubricating oil discharge clean and properly stored. Before re-activation, the equipment needs to be fully inspected and maintained, and the preparatory work should be carried out in accordance with the requirements before the first operation to ensure that the equipment can be started smoothly and run normally.
