What are the Different Types of Gear Pulleys?

Spur Gear Pulleys

Spur gear pulleys have straight teeth that are parallel to the axis of rotation. They are used in applications where speed and load requirements are moderate.

Helical Gear Pulleys

Helical gear pulleys have angled teeth, which allows for smoother and quieter operation. They are suitable for high-speed and high-load applications.

Bevel Gear Pulleys

Bevel gear pulleys have teeth that are cut on an angular surface. They are used to transmit motion between intersecting axes, often at a right angle.

Worm Gear Pulleys

Worm gear pulleys consist of a worm (screw) and a worm wheel (gear). They provide high torque and are typically used in applications requiring significant speed reduction.

Planetary Gear Pulleys

Planetary gear pulleys consist of a central sun gear, planet gears, and an outer ring gear. They offer high torque density and are used in complex motion control systems.
