This is a simple structure coupling that sandwiches a buffer material called an element (polyurethane elastomer) between two hubs. We have prepared two types of elements with different hardness levels to choose from, depending on the responsiveness in torque transmission and the amount of misalignment. Additionally, the polyurethane elastomer used for the element allows for double the torque transmission (compared to our previous models) and is designed with pre-compression on the element, enabling use with no backlash. The material of the hubs is aluminum alloy, and you can choose between key fastening and clamp fastening for securing to the shaft. 【Features】 ○ No backlash ○ Highly flexible For more details, please contact us or download the catalog.

Traditionally, power transmission with misaligned shafts has often been composed of spline shafts and universal joints, but the Schmidt coupling achieves compact and efficient power transmission. The Schmidt coupling is a misalignment coupling that utilizes the crank motion of links, where the power input at one end disk is transmitted to the other end disk via the links and center disk. Since the amount of shaft movement is determined by the length of the links, it not only allows for power transmission with misaligned shafts but also enables parallel movement of the shaft during rotation. 【Features】 ○ The eccentricity can range from 23mm to 85mm with a torque of 7850N·m. By using it to connect with the drive motor of the movable roller, the spacing between the fixed roller and the movable roller can be freely adjusted within the allowable range.

• Torque Control

This is a multifunctional and versatile damping device that simultaneously incorporates three functions: spring function, damper function, and bearing function, based on a unique principle and structure. The structure consists of a metal inner shell, outer shell, and cylindrical rubber, with the inner and outer shells having a 45° displacement and cylindrical rubber pressed in. The spring characteristics are nonlinear, and since the cylindrical rubber operates by rolling while being compressed, it experiences minimal aging deformation and is strong against impact loads, exhibiting excellent durability. **Features** - **Spring Function:** It can support loads in all directions, including tension, compression, and shear. It can tolerate a twisting angle of up to ±30 degrees. The spring characteristics are nonlinear, with twisting stiffness increasing with the increase in load. - **Damper Function:** The internal friction of the pressed cylindrical rubber is over 1000 times greater than that of metal (spring steel). Therefore, it enables amplitude reduction during resonance and early convergence of vibrations caused by impacts. - **Bearing Function:** It can support high-frequency oscillatory motion while absorbing vibrations. In general bearings, repeated oscillatory motion within a specific angular range can lead to insufficient lubrication throughout, reducing durability. The Lostas suspension solves this issue.
