The NGCL type drum toothed coupling with brake wheels is an important mechanical engineering component. The NGCL drum gear coupling with brake wheels is mainly composed of internal gear rings with the same number of teeth and flange half couplings with external teeth. The outer teeth are divided into two types: straight teeth and drum teeth. Among them, drum teeth are made into spherical surfaces, with the center of the spherical surface on the gear axis and a larger tooth flank clearance than general gears. This design allows the drum shaped gear coupling to allow for larger angular displacement (compared to the straight gear coupling), thereby improving the contact conditions of the teeth, enhancing the ability to transmit torque, and extending the service life.

Main features and Advantages

Strong load-bearing capacity: Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the load-bearing capacity of the drum shaped gear coupling is on average 15-20% higher than that of the spur gear coupling.
Large angular displacement compensation: The drum gear coupling has a large angular displacement compensation capability and can adapt to large angular deviations between two axes.
Low noise and long maintenance cycle: The drum shaped tooth surface improves the contact conditions between the inner and outer teeth, avoiding the disadvantages of edge compression and stress concentration at the straight tooth end under angular displacement conditions. At the same time, it improves the friction and wear of the tooth surface, thereby reducing noise and extending the maintenance cycle.
Easy to assemble and disassemble: The outer gear sleeve has a trumpet shaped tooth end, making it very convenient to assemble and disassemble the inner and outer teeth.

The NGCL coupling with brake wheels is particularly suitable for low-speed heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries. At the same time, it is also suitable for shaft transmission of various types of machinery such as petroleum, chemical, and general machinery. In addition, high-precision and dynamically balanced drum gear couplings can also be used for high-speed transmission, such as shaft transmission in gas turbines.

The NGCL drum toothed coupling with brake wheels comes in a range of different models and specifications to meet the needs of different working conditions and torque transmission. Its rated torque range is usually 355-100000N · m, and the allowable speed range is 4000-950r/min. Specific performance parameters and size specifications can refer to relevant standards or product samples provided by the manufacturer.

Precautions and Maintenance

Sealing state: The drum gear coupling needs to work in a well sealed state to prevent tooth wear and power consumption.
Regular inspection: The wear and working condition of the coupling should be checked regularly to promptly identify and address potential issues.
Lubrication and maintenance: According to the usage conditions and manufacturer's recommendations, perform appropriate lubrication and maintenance on the coupling to extend its service life.

The NGCL crown gear coupling with brake wheels plays an important role in the field of mechanical engineering due to its excellent performance characteristics and wide application areas.
