China Drive Coupling Manufacturer

A drive coupling is a mechanical device that connects two shafts together to transmit power or torque between them. It provides a secure and efficient connection, allowing rotational motion to be transferred from one shaft to the other. Drive couplings are designed to accommodate varying degrees of misalignment, axial movement, or angular displacement between the shafts, ensuring smooth power transmission even in situations where perfect alignment is not possible. They come in different types, such as gear couplings, jaw couplings, disc couplings, and fluid couplings, each offering specific features and benefits depending on the application requirements. Drive couplings play a crucial role in a wide range of mechanical systems, including engines, motors, pumps, and industrial machinery, enabling efficient and reliable power transfer.

Features of Drive Coupling

Drive couplings possess several key features that contribute to their functionality and effectiveness in transmitting power or torque between shafts. Some common features of drive couplings include:

Power Transmission

Drive couplings are designed to efficiently transfer power from one shaft to another. They can handle varying levels of torque and rotational speed, ensuring reliable power transmission in a wide range of applications.

Misalignment Compensation

One of the primary features of drive couplings is their ability to accommodate misalignment between the connected shafts. They can compensate for angular, parallel, and axial misalignments, allowing for smoother operation and reducing stress on the system components.

Shock and Vibration Damping

Drive couplings often incorporate features that help absorb shocks and dampen vibrations generated during operation. This helps to protect the connected equipment from excessive loads, minimize wear and tear, and enhance overall system reliability.

Torque Limiting

Certain types of drive couplings, such as fluid couplings or torque-limiting couplings, offer the ability to limit the transmission of torque when necessary. This feature can protect the system from sudden overload conditions, prevent damage to components, and improve safety.

Compact Design

Drive couplings are typically designed to be compact and lightweight, minimizing the space required for installation. This is particularly beneficial in applications where space constraints are a consideration.

Easy Installation and Maintenance

Many drive couplings are designed for easy installation and maintenance. They often feature simple and quick connection methods, allowing for convenient assembly and disassembly. Regular maintenance activities, such as lubrication or inspection, can be performed with relative ease.

Material Compatibility

Drive couplings are available in a variety of materials, including metals, elastomers, and composites. The selection of materials depends on factors such as the application requirements, environmental conditions, and the type of torque being transmitted. Material compatibility ensures optimal performance and longevity of the coupling.


Drive couplings offer cost-effective solutions for power transmission needs. They are generally durable, requiring minimal maintenance, and can help reduce the risk of equipment damage and downtime. This makes them a reliable and economical choice for many industrial applications.

Drive Coupling Application



They are delivered as installable kits for turbine manufacturers in the Netherlands and abroad.
Trouble-free installation on construction sites is guaranteed thanks to careful assembly and thorough inspection and testing at the factory. Very high delivery reliability is achieved thanks to a prudent stocking strategy.
Wind energy is an important renewable energy source, but we also know how to deal with the challenging environment of fermentation plants. EPT execution combined with a high-strength surface protection system and stainless steel components provides reliable performance in the most challenging conditions.



Oil exploration, offshore wind farm construction and dredging companies all rely on reliable drive systems. A good example from the offshore industry is the development and supply of jack-up drives for work platforms and construction vessels. On site, jack-up drives place the four outriggers on the seabed and fully lift the vessel to a safe working height above the water.

EPT also develops and produces various marine-specific motors, gearboxes and controllers. High IP ratings, static heating, special paint systems or materials, we make sure you get what you need. For this situation, EPT has developed a special extremely waterproof heated motor brake, which can be fitted with various optional equipment.

Heavy industry

Heavy Industry

Still one of the main driving forces behind the modern economy. Often censored these days due to environmental impact, yet indispensable even for today’s world. Large drives such as powering rolling mills and mobile harbor cranes. A suitable example is EPT’s travel drives for gantry cranes. These drives are subjected to heavy loads due to the continuous acceleration and deceleration of the crane and its load, often 24 hours a day, 7 days a week, summer and winter often in salty, dusty or wet conditions. Correct selection of drives is therefore crucial for reliable and economical operation, and fortunately the experts on the EPT team know the application like back to back.

Machine Building

Machine Building

Almost everything we see around us is made by machines. But first the machines themselves had to be designed and built. EPT is a reliable partner in all stages of machine development, construction and production. The stakes are electric or hydraulic motors, gearboxes or control systems. Whether you’re building conveyor systems, automatic rebar benders, milking carousels or fairground rides, you’ll find EPT by your side to move your business forward reliably, safely and economically.



Machines and technical installations are subject to technical and economic longevity. EPT actively addresses this issue by revitalizing existing machines and installations. The main goal is to increase energy efficiency and productivity. In many cases, machines and installations can even become more versatile, increasing their profitability. By replacing outdated drives and controls with modern equipment or switching from pneumatic to electric drives, the gains in energy consumption can be quite dramatic, with a correspondingly short payback period.

Drive Couplings VS Shaft Couplings

Drive couplings and shaft couplings are often used interchangeably to refer to the same mechanical device. Both terms essentially describe the same concept: a device that connects two rotating shafts to transmit power or torque between them. The choice of terminology may vary depending on industry, application, or regional conventions.

The term “drive coupling” typically emphasizes the purpose of the coupling, which is to facilitate power transmission and drive one shaft using another. It highlights the active role of the coupling in transferring power from a driver shaft to a driven shaft.

On the other hand, the term “shaft coupling” focuses on the physical connection between the two shafts. It highlights the coupling as a component that joins the shafts together, ensuring a secure and efficient connection.

In practice, there is no fundamental difference between the two terms. They refer to the same class of mechanical devices that provide a coupling mechanism between two shafts. Whether referred to as drive couplings or shaft couplings, they serve the purpose of transmitting power, compensating for misalignments, and maintaining the integrity of rotating systems.
