Distance between axis cores is adjustable! Schmidt coupling [for compactification!]

Distance between axis cores is adjustable! Schmidt coupling [for compactification!]

The "Schmidt Coupling NSS Series" allows for intentional changes in the distance between the axis cores without any deviation in rotation angle or fluctuations in transmitted torque.

Schmidt coupling (offset joint) utilizing link crank motion. When transmitting rotational force from the driving shaft to the driven shaft, it allows for free parallel movement of the axis in the vertical and horizontal directions even while rotating. Additionally, there is no imbalance force or phase shift during the axial displacement movement, and the coupling itself can automatically absorb radial oscillations between the shafts. Therefore, it improves product accuracy and lifespan, contributes to flexible product design in various fields, and promises the birth of new products. 【Features】 - Free parallel movement of both shafts is possible even during additional operation. - Absorbs radial oscillations between the driving motor and additional equipment. - No angular displacement or fluctuation in transmitted torque. - Minimal backlash and transmission loss. - Allows for significant offset in a small space. - Facilitates compact device design. If you are struggling with miniaturization and space-saving that is difficult to achieve with universal joints, please feel free to consult us! ◆ For more details, please contact us or refer to the catalog ◆

GC coupling

GC coupling

Transmission of torque in a compact and high-capacity design developed through unique technology.

- Even if there is some misalignment or runout of the axis, the torque from the driving side is reliably transmitted. - Even if the connected two shafts shift or tilt during use, they automatically adjust and absorb the misalignment, preventing excessive loads on the shafts and bearings, thus protecting the machinery. - It is a flexible coupling with crowned gears, which provides high wear resistance and robustness. - Since the center and case are separate, installation and removal are easy, and it is compact and lightweight, requiring minimal installation space. - Unlike other types of flexible couplings, there is no angular misalignment between the two shafts due to the coupling arms, making it particularly suitable for line shaft couplings, high-speed applications, and heavy load applications.

SF Coupling

SF Coupling

Shock load absorption by a lattice-shaped spring.

- Protection against misalignment of the axis The grid can freely sway within the hub's tooth grooves, allowing it to absorb misalignment without causing harmful bearing loads that occur in many other elastic couplings. - Protection against shock loads, vibrations, and thrust loads The characteristic of the SF coupling, which is its torsional flexibility, allows it to flexibly respond to changes in load conditions when subjected to normal, shock, or fluctuating loads, enabling it to undergo torsional deformation. As a result, the SF coupling absorbs shock energy in its operating system and gradually releases it to dampen vibrations, reducing overloads and shock loads by over 30%, thereby facilitating smooth operation. In other words, the characteristic of the SF coupling serves as a shock absorber for rotational motion. This property is due to the elasticity of the special tooth grooves and the Cr-V steel grid members, which effectively protect the driving and driven machines.
