Rokee® Customized NL Nylon Gear Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
NL nylon gear coupling is a transmission device that uses a combination of MC nylon inner gear ring and metal outer gear shaft sleeve.
Structural composition
Half coupling: usually made of cast iron HT20-40 or cast steel ZG35II, or high-quality materials such as 45 steel can be selected and formed through casting or forging processes. The half coupling is connected to the transmission shaft of the equipment through a key connection to achieve torque transmission.
Nylon internal gear ring: Made of high-strength nylon material (such as MC nylon or nylon 66) injection molded with a special formula, it has excellent wear resistance and self-lubricating properties. Its tooth profile has been carefully designed to tightly mesh with the outer gear shaft sleeve, ensuring smooth torque transmission.
External gear shaft sleeve: It is usually forged from high-quality alloy steel, processed with precision machining and strict heat treatment, and has high strength and hardness, capable of withstanding large torque.
During operation, the half coupling at the active end drives the outer gear shaft sleeve to rotate, and the outer teeth on the outer gear shaft sleeve mesh with the inner teeth of the nylon inner gear ring, thereby transmitting torque to the half coupling and transmission shaft at the driven end. Nylon inner gear ring not only plays a role in transmitting torque, but also utilizes its own elastic deformation to effectively compensate for axial displacement, radial displacement, and angular displacement between the two shafts, reduce vibration and impact during equipment operation, and ensure the smoothness of transmission.
Performance advantages
Maintenance free feature: The self-lubricating performance of MC nylon material eliminates the need for oil injection maintenance, reducing maintenance costs.
Vibration control: Nylon material can absorb high-frequency vibrations in the transmission system, reduce noise, and improve the stability of equipment operation.
Installation tolerance: The drum tooth design allows for a certain amount of axial movement and angular deflection, improving the flexibility and adaptability of installation.
High transmission efficiency: Through reasonable structural design and material selection, NL nylon gear couplings can achieve high transmission efficiency and reduce energy loss.
Technical Parameter
Nominal torque: ranging from tens of Newton meters for smaller specifications to thousands of Newton meters for larger models, meeting the power needs of different industrial equipment.
Allowable rotational speed: It depends on factors such as the size, mass distribution, and material properties of the coupling. Small NL type couplings have a higher allowable rotational speed, while larger type couplings have a relatively lower allowable rotational speed.Working temperature: usually operates within the range of -20~+70 ℃, suitable for various industrial environments.
NL Nilong gear couplings are widely used in fields such as fans, water pumps, lubrication pumps, chemical equipment, food processing machinery, pharmaceutical equipment, and mining machinery. Its excellent performance and adaptability make it an important component in various industrial transmission systems.
When selecting, it is necessary to focus on factors such as the maximum instantaneous torque of the transmission system, ambient temperature, and centering deviation. Ensure that the selected model of coupling can withstand the expected load and operate normally within the specified temperature range. Meanwhile, reasonable control of centering deviation can extend the service life of the coupling and improve the operational efficiency of the equipment.
NL Nilong gear couplings play an important role in many industrial fields due to their unique structure and performance advantages. In practical applications, users should choose the appropriate model based on specific working conditions and equipment characteristics to fully leverage its performance advantages.
