The driving roller, also known as the drive roller, transmission roller or drum pulley, is a drum shaped roller in a conveyor system that directly receives power (from motors, reducers, etc.) and relies on the friction between its surface and the conveyor belt to pull the belt and materials for continuous movement.
In simple terms, it is the "heart" or "feet" of the conveyor, providing the driving force for the entire system. In contrast, the driven roller (or redirecting roller) does not supply power but merely serves to support and change the direction of the belt.
A complete drive roller is typically not a single component but an assembly, primarily consisting of.
Material: usually made of steel (carbon steel, stainless steel), and the surface may be rubber-covered or knurled to increase the friction between its surface and the conveyor belt. In special applications, aluminum alloy or engineering plastics may also be used.
Shape: primarily cylindrical. Depending on requirements, it can be manufactured as a crowned roller (slightly larger diameter in the middle) to help center the conveyor belt.
Typically made of high-strength alloy steel using a thermal refining process, designed to withstand torque and bending moments.
Both ends of the shaft are fixed to the frame via external bearing housings.
One end of the shaft is machined with a keyway, square head, or directly formed into a coupling to connect with the output shaft of a reducer (or directly with a motor), thereby transmitting torque.
Based on structure and function, drive rollers can be classified into the following categories.
Single drive roller: only one drive roller provides power, suitable for medium to short-distance conveyors with moderate loads.
Multiple drive rollers: in long-distance conveyors, multiple drive rollers are installed to distribute the required high traction force.
Head drive roller: Installed at the discharge end of the conveyor, this is the most common configuration.
Intermediate drive roller: Used in ultra-long-distance conveyors, installed in the middle section of the conveyor belt to reduce the maximum tension in the belt.
Tail drive roller: Less common, where the drive roller is installed at the tail end.
When selecting a drive roller, the following key parameters need to be considered.
Diameter: Determined by the number of layers of the conveyor belt, tension, and transmitted power. Higher belt tension requires a larger roller diameter to prevent excessive bending stress.

Length: Typically 100-200 mm longer than the width of the conveyor belt to ensure effective contact and stable operation.
Shaft Diameter and Material: Determined based on calculations of the torque and resultant forces (tension, gravity, etc.) it needs to withstand.
Surface Treatment: Selected according to the environment (dry/wet), material characteristics (presence of adhesiveness), and required friction. Surface treatment like zinc-plated, anti-rust oil coating, PU coating (yellow), kurling are optional.
Although the drive roller may appear to be a simple rotating component, it serves as the core of conveyor power transmission. The quality of its design, manufacturing, and selection directly impacts the operational efficiency, reliability, energy consumption, and lifespan of the entire conveyor system. Proper selection and maintenance of the drive roller are crucial to ensuring the smooth and efficient operation of the conveyor production line.
