Application Case
Typical case of diaphragm coupling applied to variable frequency speed control equipment
JMB type coupling is applied to HangZhou Oilfield Thermal Power Plant
According to the requirements of HangZhou Electric Power Corporation, HangZhou Oilfield Thermal Power Plant should dynamically adjust the power generation according to the load of the power grid and market demand, and carry out the transformation of the frequency converter and the suction fan. The motor was originally a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Factory. The speed control mode after changing the frequency is manual control. Press the button speed to increase 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is frequently damaged, which directly affects the normal power generation.
It is found through analysis that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the fan impeller is 3.3 meters) and is cut off, which has great damage to the motor and the fan.
Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent number: ZL.99246247.9). After 1 hour of destructive experiment and more than 1 year of operation test, the equipment is running very well, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in good condition.

Comparing Drive Couplings with V-Belts and Chain Drives for Power Transmission
Drive couplings, V-belts, and chain drives are all common methods used for power transmission in various industrial applications. Each method has its advantages and disadvantages, and the choice depends on the specific requirements of the application. Let’s compare these three power transmission methods:
- Drive Couplings: Drive couplings provide a direct connection between two shafts, offering high efficiency and torque transmission. They are ideal for applications where precise motion transfer is required without slippage. Drive couplings also accommodate misalignments between shafts, reducing the need for precise alignment. However, they may not be suitable for applications with large misalignments or significant shock loads.
- V-Belts: V-belts are flexible power transmission components that use friction to transfer power. They are easy to install, absorb shocks and vibrations, and offer overload protection due to their ability to slip when overloaded. V-belts are suitable for applications with moderate misalignments and can be cost-effective. However, they are less efficient than drive couplings and may require periodic tension adjustments and replacements due to wear.
- Chain Drives: Chain drives use toothed chains to transmit power between sprockets. They are known for their high efficiency and ability to handle high loads and speeds. Chain drives are suitable for long-distance power transmission and can operate in harsh environments. They offer excellent precision and minimal slippage. However, chain drives require periodic lubrication and maintenance to prevent wear and ensure smooth operation. Additionally, they may produce noise and vibration during operation.
In summary, the choice between drive couplings, V-belts, and chain drives depends on factors such as the level of misalignment, required efficiency, load capacity, speed, environmental conditions, and maintenance considerations. Drive couplings are well-suited for applications requiring precise motion transfer and minimal maintenance, while V-belts offer flexibility and overload protection. Chain drives excel in high-load and high-speed applications but require regular lubrication and maintenance.
Exploring the Use of Elastomeric Materials in Flexible Drive Couplings
Elastomeric materials play a vital role in the design and function of flexible drive couplings. These materials are known for their unique properties, including flexibility, resilience, and damping capabilities, making them well-suited for various power transmission applications. Here are some key aspects of elastomeric materials in flexible drive couplings:
- Flexibility: Elastomeric materials, such as natural rubber and synthetic elastomers like polyurethane and neoprene, exhibit high flexibility. This flexibility allows them to deform under load, accommodating misalignments and absorbing shocks and vibrations during operation. The ability to flex helps prevent undue stress on the connected machinery and ensures a smooth and reliable power transmission.
- Damping: Elastomers possess excellent damping characteristics, which means they can absorb and dissipate energy when subjected to torsional vibrations and dynamic loads. This damping property is crucial in minimizing resonance and preventing harmful vibrations from propagating through the system. Couplings with good damping capabilities offer improved system stability and reduced wear on components.
- Resilience: Resilience refers to the ability of elastomeric materials to return to their original shape after being deformed by torque or misalignment. This property ensures that the coupling remains functional even after experiencing temporary overloads or torsional stresses. The resilience of elastomers contributes to the longevity and reliability of the coupling.
- Easy Installation: Elastomeric couplings are often designed with a simple and compact structure, making them easy to install and maintain. Their flexibility allows for quick assembly and disassembly, which can be advantageous during equipment maintenance and repairs.
- Misalignment Compensation: The high flexibility of elastomeric materials allows the coupling to compensate for both angular and parallel misalignments between shafts. This ability to tolerate misalignments without transmitting excessive loads to connected equipment protects the machinery from premature wear and damage.
- Cost-Effectiveness: Elastomeric couplings are generally more cost-effective compared to other types of couplings with elaborate designs. Their simple construction and use of elastomeric materials make them an economical choice for various industrial applications.
Elastomeric materials offer a compelling combination of mechanical properties that make them highly suitable for flexible drive couplings. When selecting a coupling for a specific application, considering the type and characteristics of the elastomeric material used is crucial to ensure the coupling meets the performance requirements and environmental conditions of the system.
Types of Drive Couplings and Their Applications in Various Industries
Drive couplings come in various types, each designed to meet specific application requirements. Depending on the industry and the type of machinery involved, different types of drive couplings are used to optimize power transmission efficiency and reliability. Here are some common types of drive couplings and their applications in various industries:
- Jaw Couplings: Jaw couplings are flexible couplings that use elastomeric inserts to transmit torque. They are commonly used in industrial pumps, compressors, and conveyors. The elastomeric inserts provide shock absorption and vibration dampening, making them suitable for applications where misalignment and vibration are present.
- Gear Couplings: Gear couplings are robust and torsionally rigid couplings that use gear teeth to transmit torque between shafts. They are often used in heavy-duty applications such as steel rolling mills, paper mills, and marine propulsion systems. Gear couplings can handle high torque and misalignments, making them ideal for demanding industrial environments.
- Disc Couplings: Disc couplings use thin metal discs to transmit torque and accommodate misalignment. They are widely used in high-speed applications, such as gas turbines, generators, and test rigs. Disc couplings offer high torque capacity and are known for their torsional stiffness and balance characteristics.
- Grid Couplings: Grid couplings use a grid-like flexible element to transmit torque. They are commonly used in industrial pumps, fans, and compressors. Grid couplings offer excellent shock absorption and misalignment capability, making them suitable for applications where protection against sudden shocks is required.
- Tyre Couplings: Tyre couplings use an elastomeric tyre between two hubs to transmit torque. They are widely used in various industries, including steel, mining, and power generation. Tyre couplings can accommodate misalignments and provide vibration damping, making them versatile for different industrial applications.
- Bellows Couplings: Bellows couplings use a thin-walled metallic bellows to transmit torque and compensate for misalignments. They are commonly used in precision motion control applications, such as robotics, CNC machines, and medical equipment, where minimal backlash and high torsional stiffness are required.
- Universal Joints: Universal joints are used to transmit torque between shafts at an angle. They are commonly found in automotive drivelines, agricultural equipment, and industrial machinery. Universal joints allow angular misalignments and are widely used in applications where rotational movement must be transferred through non-aligned shafts.
The choice of drive coupling type depends on factors such as torque requirements, speed, misalignment, and specific environmental conditions. Each type of coupling has its unique advantages and limitations, and selecting the right coupling for a particular application is crucial for ensuring optimal power transmission and machinery performance in various industries.
