پولی 20 دندانه GT2 شفت 8 میلیمتری

Description:
GT2-20 Teeth Aluminum Timing Pulley [8mm Bore] package contains synchronous toothed pulley that are used in the linear movement belt mechanism of the 3D printer. Most of the 3D printer needs a linear motion, but motors offer rotational motion, so a mechanism is needed to convert the rotational motion to the linear motion. Most 3D printers use a mechanism consist of leadscrews and timing belts. In the printing process, the leadscrew moves the hot end to upward or haet bed to downward to create a linear movement along Z-axis. Belts translate the rotational motion of the motor to linear motion in X and Y-axis. A belt mechanism consists of a coach fixed to the belt, a toothed pulley (sprocket) connected to the step motor and a timing belt with teeth. The belt teeth fit into the notches of the toothed pulley, preventing it from slipping, and allowing it rotates with the motor, so keeping the belt taut is a very important factor in timing.

This toothed pulley is made of a strong, durable, and lightweight material (aluminum) with an 8mm inner hole diameter that can firmly mount on any 8mm shaft especially step motor shaft and also can be more fastened to the shaft with 2 screws. On the other hand, This pulley has a 2mm pitch, 7.4mm tooth width that is specialized for 6mm GT2 timing belt series, to achieve precision linear movement, but the XML timing belt slips because of the different tooth arrange.
