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

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.

DC coupling

No refueling, non-backlash, maintenance-free

1. No lubrication required There are no friction or rolling parts, so greasing or oiling is completely unnecessary. 2. Maintenance-free As long as it is used in a normal state, inspection only requires checking for looseness of bolts and nuts. 3. No backlash With no backlash and high torsional rigidity, there is no rotational variation, allowing for precise phase control. 4. High torque transmission Optimally designed to be compact while transmitting high torque. 5. Easy installation and removal The DCP type integrates the disk element, bush, and washer into a single package, making coupling and uncoupling extremely easy. 6. High allowable rotational speed A high-precision bush is inserted between the element and the bolt, allowing for extremely high rotational speeds compared to other couplings. 7. Large allowable misalignment The allowable misalignment is large, with an angular misalignment of 0.5 to 1°, and the allowable parallel offset can be increased according to the length of the spacer. 8. Low thrust load The thrust load generated by the coupling is small, significantly reducing the burden on the drive shafts and bearings of the prime mover and driven machine.
