Pulleys for toothed belts in 3D printers and CNC machines

Timing belt pulleys are a key component of many drives, including those found in 3D printers and CNC machines. These components take care of the transmission of motion from the motor to the moving parts of the machine, ensuring precise movements and positioning.

Basic structure of the pulley:

Profile: The profile of the pulley must match the profile of the belt to ensure proper transmission of forces and prevent slippage. The most common profile for 3D printers and CNC machines is the GT2 profile, but there are other types such as MXL, HTD and T2.5/T5/T10.

Teeth: These serve to secure the belt and prevent it from slipping. The number of teeth on the pulley affects its diameter and thus the speed and force of the transmission.

Drill: The bore is the hole in the middle of the pulley that allows it to be mounted on the motor shaft. Its size and shape (e.g. with or without crank) may vary according to the engine specifications.

Dimensions and specifications:

Width: The width of the pulley should match the width of the belt. For 3D printers and small CNC machines, 6 mm wide belts are often used, but there are also wider or narrower variants.

Diameter: the diameter of the pulley is usually proportional to the number of teeth. Larger pulleys can move the axis faster but may require more force.

Material:

The standard material for the production of pulleys for 3D printers and CNC machines is aluminium. Aluminium is lightweight, durable and has good thermal properties, ensuring that the pulley remains stable even at high speeds. In some applications we can also find pulleys made of plastic or steel, but aluminium pulleys are usually preferred for their combination of lightness, strength and durability.

Conclusion:

Timing belt pulleys are an essential part of many machines that require precise motion. When selecting a pulley, it is important to consider the type of belt, the required
