VULKAN VULASTIK L is a highly flexible axial coupling used for various industrial applications and four qualities of rubber and silicone couplings are available in order to adjust the coupling according to different system needs.
VULASTIK L coupling parts include hub and flange body.
This disc element is vulcanized on its inner radius, the outer radius is connected to the flange cover by a plug tooth and can also be used for power generation and auxiliary drives.
VULKARDAN P
PTO use cases are when it is not in the main drive equation or it travels a very long distance where diesel engines are considered as the main drive.
The main components of the VULKARDAN P coupling are internal and external couplings that are opposite each other and have high torsional flexibility and good damping properties.
VULKARDAN F
VULKARDAN F can be used instead of VULKARDAN E, which is well established and one of the flexible products of VULKAN, and its design can lead to a reduction in weight and a very short installation length.VULKARDAN F is suitable for flexibly mounted drive systems and allows compensation of radial, axial and angular deviations.
VULKARDAN F is available in four tires. Among the benefits of this type of coupling, it can be said that it is used in high alternating installation torques and the damage caused by temperature is effectively reduced. And it is easy to install.

Functionality Explained
The true power of Vulcan couplings lies in their ability to address critical challenges in rotating machinery:
Conquering Torsional Vibrations: Rotational shafts are susceptible to vibrations that cause them to twist back and forth. These vibrations, often caused by engine imbalances, gear meshing, or fluctuating loads, can wreak havoc on connected components. Fortunately, Vulcan couplings come to the rescue. The elastomer element acts as a shock absorber, effectively dampening these torsional vibrations.
Taming Misalignment: Perfect alignment between connected shafts is a utopian ideal in real-world applications. Manufacturing tolerances, thermal expansion, and foundation settling can all contribute to misalignment. This flexibility allows them to accommodate a certain degree of misalignment, preventing binding, wear, and potential component failure.
Absorbing Shock Loads: Rotating machinery can be subjected to sudden increases in torque, such as during startup or during abrupt changes in load. Vulcan couplings are enable to absorb these shock loads. By acting as a buffer, they significantly reduce the impact on connected components, safeguarding them from damage and extending their lifespan.
Benefits and Advantages of Vulkan Couplings
Vulkan couplings, also known as elastomeric couplings, offer several advantages over other types of couplings used in shaft connections.
Here’s a breakdown of their key benefits:
• Misalignment Accommodation: One of the biggest strengths of Vulkan couplings is their ability to handle misalignment between shafts. This misalignment can be caused by factors like thermal expansion, shaft deflection under load, or slight manufacturing tolerances. The elastomeric element in the coupling acts like a flexible joint, absorbing these misalignments and reducing stress on bearings and other components.
• Shock and Vibration Damping: Rotating machinery can generate shock loads and vibrations. Vulkan couplings, with their elastic properties, help dampen these vibrations, protecting connected equipment from damage and extending its lifespan. This is particularly important for applications with high shock loads or variable speeds.
• Reduced Noise Transmission: The vibration damping characteristic of Vulkan couplings also translates to reduced noise transmission. This is beneficial in applications where noise reduction is a critical factor, such as in buildings with sensitive equipment or in noise-restricted environments.
• Low Maintenance: Unlike some other couplings that require regular lubrication, Vulkan couplings are generally maintenance-free. The elastomeric element is designed to last for a long service life, minimizing downtime and maintenance costs.
• Compact Design: Vulkan couplings are known for their compact size compared to other types of couplings with similar torque capacities. This allows for a more space-efficient design in machinery and equipment layouts.
• Easy Installation and Removal: The elastomeric design also contributes to the ease of installation and removal of Vulkan couplings. This simplifies maintenance procedures and reduces downtime during equipment servicing.
• High Speed Capability: Vulkan couplings can accommodate high rotational speeds, making them suitable for various applications like turbines, generators, and high-speed pumps.
• Extended Equipment Life: By mitigating vibrations, misalignment, and shock loads, Vulcan couplings play a vital role in protecting connected components from wear and tear.
• Smooth Starts and Stops: The fluid transmission mechanism allows for smooth acceleration and deceleration, reducing shock loads on connected machinery and extending equipment lifespan. This makes them particularly valuable for applications with high inertia loads like large motors and generators.
Overall, Vulkan couplings offer a compelling combination of benefits for various shaft coupling applications. Their misalignment tolerance, vibration damping, noise reduction, low maintenance requirements, and compact design make them a popular choice for engineers seeking reliable and efficient power transmission.
