Couplings

Power transmission couplings that meet your specific needs

Due to reduced time and resources, machine designers are under pressure to increase the performance of power transmission systems. A variety of industrial couplings, including customized products, help these systems work effectively and efficiently. Factors such as size and torque requirements determine the most appropriate coupling to use.

We offer all major industrial coupling types, including Grid, Gear, Flex and Jaw Couplings. In addition, we supply flexible couplings that use oil injection and flexible shaft couplings for mounting and dismounting. The industiral shaft couplings compensate for four types of shaft misalignment: angular, offset, combination of the two, and axial motion. Grid couplings are aimed at high output, high torque gear applications, whereas gear couplings are heavy-duty products with large bore capacities.

Most products offered by Emechmart are made of cast iron, although some products like such as chain couplings use carbon steel. The Surface treatment technology implemented by our industrial couplings manufacturers includes phosphate coating that helps protect against corrosion. Check out our diversified range of couplings.

Benefits of couplings for your industrial application

A shaft coupling can perform several functions in the machine. The design may incorporate more than one of these coupling features into the product function in advanced applications.

Power transmission

In most cases the primary purpose is the transmission of power and torque from the driving shaft to the driven shaft - for example, a coupling connecting a motor to a pump or compressor.

Absorbs shock and vibration

A shaft coupling can smooth out any jerks or vibrations from the driving element to the driven element. This feature minimizes wear on components and prolongs the service life of the setup.

Adjust any misalignment

Misalignment between shafts may be caused by initial mounting errors or may develop over time for other reasons. Most couplings can acclimate some span of misalignment (axial, angular and parallel) between shafts.

Interruption of heat flow

Shaft couplings can also impede the flow of heat between connected shafts. If the prime mover heats up during operation, the machinery on the drive side is protected from exposure to this heat.

Overload protection

Overload Protection Special couplings known as mechanical couplings are designed for the purpose of overload protection. Upon sensing an overload condition, these torque limiting couplings break the connection between the two shafts. They are either slipped or cut to protect sensitive machines.

Types of couplings

Couplings come in many different shapes and sizes. Some of them work best for general applications, while others are actually custom-designed for specific scenarios. In order to make an informed choice, it is important to be aware of the capabilities and distinctions of the various types of couplings. This section demonstrates information about the following types of couplings and how they work:

• hard relationship
• flexible connection
• sleeve or muff coupling
• Split Muff Coupling
• Flange Coupling
• gear coupling
• Universal Joint
• diaphragm coupling
• jaw attachment
• beam coupling
• fluid connection
