Provided High Speed Helical Gear Box is more efficient than single helical gear boxes or widely used in high speed plants like turbo generators, turbo compressor, boiler feed pumps applications. A gear box is a mechanical device utilized to increase the output torque or change the speed (RPM) of the motor. The motor's shaft is attached to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio. Further, provide gear boxes are mainly used in high-speed applications. Our offered High Speed Helical Gear Box is quieter in operation than straight gear teeth gearboxes, which may improve their overall efficiency.
