SA Series Hollow Shaft Helical Gearbox
A helical gearbox is a mechanical transmission system that uses helical gears to transfer power between two rotating shafts. They are commonly used in industrial applications that require high torque and efficiency.
SA series is hollow shaft mounted. The same model can be equipped with different-speed power motors for the SA series spiral worm gearbox. Connecting various models makes it easy to realize the combination: high transmission efficiency and single reducer efficiency up to 96%. And transmission ratio division is a fine, wide range. The combined mode can form a larger transmission ratio and achieve lower output speed. SA series spiral worm gearbox can be used in the foot, B5 flange, B14 flange, hollow shaft, twisting arm, and other installation forms.
The SA series spiral worm gearbox is designed and manufactured using a modular combination system. There are many motor combinations, installation forms, and structural options. The wide range of transmission ratios can meet the different working conditions of customers.

Advantages Of Helical Gearbox:
Helical gearboxes offer several advantages over other types of gearboxes, including:
Higher torque capacity: Helical gears in a helical gearbox have a larger contact area than spur gears, which allows them to deliver higher torque loads.
Smooth and quiet operation: The Angle of the helical gears’ teeth allows them to gradually make contact with each other, resulting in a smooth and quiet operation compared to spur gears.
Higher efficiency: Helical gears in helical gears are more efficient than other types of gears, resulting in reduced power losses and improved energy efficiency.
Higher Carrying capacity: Helical gearboxes have higher carrying capacity compared to other types of gearboxes, which makes them suitable for heavy industrial applications.
Longer life: Smooth and progressive meshing of helical gears results in less wear and tear, which extends the life of the gearbox.
Helical Gearbox Application:
Conveyor systems: Helical gear boxes are commonly used in conveyor systems to transfer power between the motor and the conveyor belt.
Mining equipment: Helical gear boxes are used in mining equipment such as crushers, grinders and conveyors to handle heavy loads and high torque requirements.
Power generation: helical gear box is used for wind generator, hydraulic generator and other power generation equipment, to transfer the power of the rotor to the generator.
Marine applications: Helical gear boxes are used in Marine applications such as ships and boats to transfer power between engines and propellers.
Industrial machinery: Helical gear boxes are widely used in industrial machinery, such as pumps, mixers and extruders, to transfer power between the motor and the equipment being driven.
Automotive applications: Helical gear boxes are used in automotive applications such as transmissions and differentials to transfer power between the engine and the wheels.
