The Pulley Wheel 6.5cm x 4cm for Gear Motor is a plastic pulley measuring 65mm outer diameter, 40mm face width, and 6mm shaft bore, designed for belt drive and cord transmission applications with DC gear motors. This pulley wheel differs fundamentally from the robot car drive wheels in StemVolt’s lineup — rather than making direct contact with the floor for traction, this pulley wheel for dc motor runs a belt, rubber band, or cord between two pulleys to transmit rotational power from a motor shaft to a second driven shaft positioned at a distance from the motor.
The 6cm pulley wheel price-accessible belt drive configuration allows builders to achieve speed reduction without a gear train — pairing this 65mm driven pulley with a smaller diameter driving pulley on the motor shaft produces a speed reduction proportional to the diameter ratio. For example, a 20mm motor pulley driving this 65mm pulley produces a 65:20 = 3.25:1 reduction, slowing the output shaft to less than a third of motor speed while multiplying torque proportionally. This pulley wheel for gear motor approach is also useful when the motor and driven shaft cannot be co-axially aligned, since a belt transmission allows the two shafts to be offset by any distance the belt length permits.
The 40mm wide face of this pulley wheel for project accommodates wider belts or multiple belt passes side by side on the same pulley, increasing the total power transmission capacity compared to a narrower pulley. Available from StemVolt, offer robotics wheels at competitive prices.
