Rokee® Customized Flange Coupling With Expansion Sleeve for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The flange coupling with expansion sleeve, as an important component in the field of mechanical transmission, occupies a key position in industrial applications with its unique structural design and excellent performance. This type of coupling perfectly combines the stability of flange connection with the keyless connection advantage of expansion sleeve, providing a reliable and efficient torque transmission solution for various rotating equipment.
The flange coupling with expansion sleeve is an innovative mechanical transmission connection device that combines traditional flange coupling with expansion sleeve technology to achieve superior performance. The core design concept of this coupling is to use the friction fastening principle of the expansion sleeve to replace the traditional keyway connection, thereby eliminating the problem of weakened shaft strength caused by keyway processing. In practical applications, flange couplings with expansion sleeves demonstrate higher transmission accuracy and simpler installation and maintenance processes, making them an ideal choice for upgrading modern industrial equipment.
The flange coupling with expansion sleeve consists of stainless steel metal diaphragm group, flange type half coupling, Z1 type expansion sleeve, high-strength bolts and other components. The core transmission principle is: torque is input through the flange, transmitted to the driven shaft through elastic deformation of the diaphragm group, and the expansion sleeve achieves keyless connection between the shaft hub through radial expansion of bolts. Typical products such as the ZJM series adopt a double flange design, and the diaphragm group can compensate for ± 0.5mm axial displacement and ± 1.5 ° angular deviation. At the same time, the expansion sleeve provides a contact pressure of up to 150N · m/㎡.
Over the years, with excellent quality, we have been continuously providing many coupling products of various categories and uses complying with multiple standards and a full range of services, from the product selection to final installation and operation, for the industry fields of ferrous metallurgy, nuclear power, gas turbine, wind power, ropeway construction, lifting transportation, general equipment, etc. We strictly comply with quality system requirements and implement the whole process control to become a reliable and trustworthy partner of customers.
