For 40+ years, Manglam Engineers has been supplying reliable, high-quality Tyre couplings for Indonesian industries, providing custom solutions and ensuring consistent performance.
Powering Indonesia’s Cement & Power Plants with Tyre Couplings
1. Cement Industry
Indonesia’s cement production drives infrastructure and housing projects. Major players like Semen Indonesia and Indocement operate 24/7 plants to meet demand. These plants face tough conditions, such as high stress, dust, and vibrations, requiring durable components like Tyre couplings for reliable operation. Challenges include extreme weather and geological factors.
2. Power Industry:
The power sector is expanding rapidly to meet rising demand. Indonesia’s grid relies on a mix of coal, geothermal, and increasing renewables. With continuous operation under harsh conditions, power plants need equipment that can handle high temperatures, vibrations, and shock loads. Geographical challenges like humidity and remote locations also demand reliable, low-maintenance equipment.
What Are Tyre Couplings?
Tyre couplings are a type of flexible coupling designed to transmit torque between two shafts while compensating for misalignment, shock loads, and vibrations.
The construction and working principles of Tyre couplings make them ideal for cement and power plants, where heavy-duty machinery operates under extreme conditions.
Key Components:
- Flanges: Typically made of steel, these flanges connect the driving and driven shafts.
- Rubber Element: The rubber "Tyre" in the center of the coupling absorbs shocks and compensates for misalignments. The rubber is reinforced with fabric or steel for added strength.
Working Principle:
Tyre couplings transmit torque through torsional shear within a flexible rubber element clamped between two hubs. As torque is applied, this element deforms, allowing it to absorb shock loads, accommodate significant shaft misalignments, and effectively dampen vibrations.
Performance Specifications:
- Angular Misalignment: Up to 4°
- Parallel Misalignment: Up to 6mm
- Axial Misalignment: Up to 8mm
- Torsional Flexibility: Up to 12° at maximum torque
These performance capabilities make Tyre couplings ideal for applications in cement and power plants, where misalignment and shock loads are common.
Features of Tyre Couplings
- No Maintenance Required: Once this coupling is installed, you don't need to worry about regular check-ups or service. You can just set it up and let it run without any further attention.
- Easy and Effortless Installation: Putting this coupling in place is a very simple and quick process. You don't need special tools or a lot of time, which makes the setup hassle-free.
- Lubrication Free: The rubber part can be replaced quickly without moving heavy machinery, reducing downtime significantly.
- Flexibility and Torsional Resilience: The coupling is very flexible, allowing it to bend and twist safely when machinery starts or stops suddenly.
- High Misalignment Capability: It functions effectively even if the two machine shafts are not perfectly aligned. The coupling's flexibility easily accommodates small offsets, whether angular or parallel.
- Vibration Dampening: The rubber in the coupling acts like a sponge for vibrations and shaking. It absorbs this movement, which leads to quieter operation and protects the machinery from damage.
