Rokee® Customized Expansion Couplings for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
Expansion coupling is a special type of coupling characterized by the use of expansion sleeves to connect and transmit torque between shafts. The expansion coupling tightly connects two shafts together through an expansion sleeve. Tightening sleeves are usually made of high-strength materials with a certain degree of elasticity. During installation, place the expansion sleeve between the two shafts and use some method (such as tightening bolts) to cause elastic deformation of the expansion sleeve, thereby tightly embracing the two shafts. In this way, when one shaft rotates, it can transmit torque to the other shaft through the expansion sleeve.
Main characteristics of expansion coupling
High torque transmission capability: The expansion coupling can transmit high torque and is suitable for various heavy-duty and high-speed transmission systems.
Zero rotation clearance: Due to the tight fit between the expansion sleeve and the shaft, the expansion coupling can achieve zero rotation clearance, improving the accuracy and stability of the transmission system.
Simple structure: The structure of the expansion coupling is relatively simple, easy to install and disassemble, and reduces maintenance costs.
High reliability: The expansion coupling has high reliability and durability, and can operate stably in harsh working environments.
Expansion couplings have a variety of types and specifications to choose from to meet the needs of different transmission systems. Common types include high rigidity couplings with expansion sleeves and diaphragm couplings with expansion sleeves. These couplings have different parameters such as aperture, length, material, and torque transmission capacity, and users can choose according to their actual needs.
Expansion coupling is widely used in various mechanical equipment and transmission systems, such as servo motors, stepper motors, metallurgical machinery, mining machinery, etc. They play an important role in transmitting torque, connecting shaft systems, improving transmission accuracy and stability in these fields.
Advantages of expansion coupling:
High torque transmission: The expansion coupling can transmit high torque and is suitable for heavy-duty and high-speed transmission.
High precision: Due to the design of zero backlash, the expansion coupling can improve the accuracy and stability of the transmission system.
Easy installation: The structure of the expansion coupling is simple, easy to install and disassemble, and reduces maintenance costs.
Disadvantages of expansion coupling:
The requirements for the shaft are high: the expansion coupling requires the shaft to have a certain surface hardness and roughness to ensure a tight fit between the expansion sleeve and the shaft.
High cost: Compared to some traditional coupling types, the cost of expanding couplings may be higher.
