Most small and medium marine gears use wet-type multiplate hydraulically-operated clutches, which enable more compact products and easier operation, as well as more rational operation and energy saving on vessels, through a wider range of clutch slipping.
We also make the most of our design and fabrication skills for large, high-precision cylindrical gears and conical involute gears etc. to offer the optimum gearboxes for ships serving a wide range of applications. They include large marine gears, conical drive marine gears, planetary gear marine gears, and electronically-controlled marine gears.
We have been working to increase the numbers of shifts in transmissions for diesel railcars, to improve their drive performance and fuel economy. We have reached 96% overall efficiency in our newly developed, direct-linked four-speed models, which are air-cooled and have no oil cooler. We have also developed products such as transmissions with wet-type multiplate braking fixed speed governors, which allow movement at a constant low speed, and CSUs (constant speed unit for generator drive) using slipping clutch technology. The latter can drive a generator for onboard power supply at a constant speed (frequency) even as the speed of the propulsion engine, or the load on it, varies.
The use of these transmissions helps to save labor and energy on railcars.
We provide reduction and step-up gears, fluid couplings and other components that are applicable to a wide range of applications, including construction machinery, industrial vehicles, pumps, gas turbine generators and mills.
These transmissions include the Omega Clutch and reduction gear with built-in torque limiter, which apply slipping clutch technology.
We also produce this torque limiter as a standalone unit, which can be built into gas turbine generation systems to improve commercial power outage countermeasures.
