SAF Series Hollow Shaft Output 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.
SAF series spiral worm gearbox is one of the four series spiral gear reducers. We use highly rigid cast iron as its shell material, which has a large bearing capacity. The inner hard tooth surface gear is made of high-quality alloy steel. The surface is carburized, hardened, and hardened. The hardness of the tooth surface is up to 58-62hrc, and the grinding accuracy of the tooth surface is up to 56. The worm gear part is made of wear-resistant high-quality copper, fine grinding teeth, smooth transmission, low noise, large bearing capacity, low-temperature rise, and long service life.
From the box to the inner gear, the SAF series spiral worm gearbox adopts a utterly modular structure design suitable for mass production. The selection is flexible. This type of gearbox model is divided in the form of reduced torque. Compared with the traditional equal proportion division, it can better meet the requirements of customers and avoid power waste.

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.
