JS Series Professional Gearboxes

- Platform-led, Modular Excellence: Built on the basis of advanced platform system, the modular design of JS series scraper gearboxes is unique. This design allows the interchangeability of parts to reach a new height, in the production process, greatly simplifies the assembly process, reduces the cost of labor and time, and improves production efficiency. And when the equipment needs maintenance, its advantages are more prominent, maintenance personnel can quickly and easily replace damaged parts, as to the equipment quickly “stop the bleeding and heal the wound”, minimize downtime, protect the continuity of underground coal mine operations, save a lot of economic losses caused by downtime for the enterprise, so that the overall operation is more smooth and efficient.

- Sleek structure and compact selection: Adhering to the modular design idea, the gearbox has a compact structure like a precise mechanical cube. The close coordination of each module not only effectively saves installation space and enables the equipment to be laid out more rationally in the limited space of underground coal mines, but also significantly shortens the delivery period without affecting the performance. This is like opening a “fast track” for coal mine producers, which can be put into use faster, meet production demands in time, and improve the flexibility and timeliness of production plans.

- Gear fine-tuning, worry-free transmission: The unique gear trimming technology is like the “tuner” of the gearbox, carefully sculpting every detail of the gear. Through the precise trimming of the tooth profile and tooth direction, the gears mesh like silent dancers in the meshing process, working together seamlessly. This makes the transmission smoother and smoother, effectively reduces the shock and vibration, as if for the operation of the equipment to lay a layer of “silent carpet”, significantly reducing the noise. At the same time, it also greatly reduces the wear and tear of the gears and extends the service life of the gear box, providing a reliable Power transmission guarantee for long-time, high-intensity operations underground in coal mines.

- Multiple sealing, leakage prevention pioneer: A variety of sealing forms are like a strong “shield”, guarding the gearbox in all aspects. Whether in regular working conditions or special harsh environments, it can effectively prevent the leakage of lubricating oil and the intrusion of impurities. The special sealing structure even plays a key role at critical moments, such as in the high humidity and dusty environment of coal mine underground, it can stand firm like a loyal guard to ensure that the internal gear box always maintains a clean and stable operating environment, reduces the risk of failures due to leakage, and improves the reliability and safety of equipment operation.

- Extra large inclination angle, efficiency leap: large inclination angle design is a highlight of JS series scraper gearbox, which gives the main machine stronger adaptability. In coal mining operation, facing the complex terrain and mining conditions, it can easily cope with the transportation demand of large inclination angle, so that the working efficiency of scraper conveyor, scraper transporter for downstream channel and other equipments has been significantly improved. As to the coal mine production equipped with a “gas pedal”, accelerate the transportation and transfer of materials, improve the overall production efficiency of coal mining, and create greater economic benefits for the enterprise.

 

- Speed ratio range: 3.5-40, this speed ratio range provides abundant speed choices for scraper, transfer machine and other equipment. According to different coal mining process and transportation requirements, the speed ratio can be flexibly adjusted, so that the equipment can be accurately matched in the process of starting, running and stopping, to ensure smooth and efficient transportation of coal materials, and improve the controllability and stability of the production process.

- Power range: 40-1,600 (kW), the wide power range is like a powerful power source, which can meet the power demand of different sizes of scrapers and transfer machines. From local mining operations in small coal mines to large-scale production scenarios in large coal mines, we can find suitable power models, which can provide continuous, stable and powerful power support for coal mine production, and ensure that the equipment can operate normally under various working conditions.

 

It is mainly applied to key equipment in coal mine underground such as scraper conveyor and transfer machine. In the scraper conveyor, it is the core power component of material conveying, driving the scraper chain to run stably, and transporting coal from the coal mining face continuously. On the scraper transfer machine for down channel, it undertakes the important task of coal transfer to ensure the smooth connection between different transportation links of coal. It is the indispensable “power heart” of the synthesized mining face under the coal mine, and plays a vital role in the efficient and safe operation of the whole coal mine production.

 

- Before installation, be sure to carefully check the appearance of the gear box for any damage, check whether the model and specification match with the scraper, transfer machine and other equipment, ensure that the installation environment is clean and free of debris, the installation foundation is firm and reliable, and operate in strict accordance with the installation instructions, so as to avoid equipment failures or safety accidents caused by improper installation.

- Regularly conduct a comprehensive inspection of the gear box, including gear wear, bearing operation status, sealing effect of seals, etc., according to the operating hours and conditions of the equipment, timely replacement of lubricating oil and wearing parts, to ensure that the gear box is always in a good state of operation, to extend the service life of the equipment.

- In the process of equipment operation, pay close attention to the operating parameters of the gear box, such as temperature, vibration, noise, etc., if abnormalities are found should be immediately shut down to check, investigate the cause of the failure and repair, strictly prohibit the equipment to run with faults, to prevent the expansion of the failure, endangering the safety of personnel and the progress of the production of coal mines.

- Coal mine underground environment is complex and harsh, we should pay attention to the protection of the gear box, to avoid flooding, impact, coal dust accumulation and other impacts, regularly clean up the surface of the equipment, coal dust and debris, keep the equipment heat dissipation is good, to ensure that it is still in the harsh environment can run stably and reliably.
