Rokee® Customized Large Universal Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
Universal coupling is a mechanical component used to connect two shafts (active shaft and passive shaft) in different mechanisms, allowing them to rotate together to transmit torque. Its core function is to solve the problem of axis misalignment, allowing the two axes to achieve continuous rotation even when there is an angle between the axes.
The universal coupling utilizes its special hinge structure to allow the two connected shafts to deflect relative to each other within a certain angle range. When the driving shaft rotates, the rotational motion and torque are transmitted to the driven shaft through the intermediate transmission components of the coupling (such as the cross shaft, ball cage, etc.), which can maintain the continuity of the transmission even if there is angular deviation or axial displacement between the two shafts.
Universal couplings with different structural types have different angular compensation capabilities, and the angle between the two axes is generally between 5 ° and 45 °. This compensation capability makes it particularly suitable for situations where installation is difficult or relative displacement occurs during the work process. The universal coupling has a compact structure and a transmission efficiency of up to 98-99.8%, which has a significant energy-saving effect in high-power transmission. At the same time, some well-designed universal couplings also have the functions of buffering, vibration reduction, and improving the dynamic performance of the shaft system, which can improve the working performance of the entire transmission system.
Cross axis universal coupling is the most common type and the most widely used universal coupling in industrial applications. It consists of two fork shaped joints and a cross shaft, with the four necks of the cross shaft connected to the two fork shaped joints through needle roller bearings. According to the changes in the bearing seat and cross head, the cross shaft universal coupling is divided into various forms such as SWC type integral fork head, SWP type partial bearing seat, SWZ type integral bearing seat, etc. Both heavy-duty and small-sized cross axis universal couplings are universal, while industries such as automobiles have specialized designs.
