Belt Driven Roller Conveyor for Light to Medium L | RFQ Sourcing Details

Home > Porducts Detail Belt Driven Roller Conveyor for Light to Medium Loads 05/10/2025 admin Belt-driven roller conveyors use belts (typically flat or round) to transmit power from a motor to rollers, offering a quieter and smoother alternative to chain-driven systems, though they are less common for heavy-duty applications.

Below is a comprehensive guide on belt-driven roller conveyors, covering their design, components, selection process, pricing, etc. What is a Belt-Driven Roller Conveyor?

A belt-driven roller conveyor is a powered conveyor system where rollers are driven by a motor via belts (flat, round, or O-ring belts) that connect the motor or a drive shaft to the rollers. The belts transfer rotational force, causing the rollers to move loads along the conveyor.

These systems are quieter and smoother than chain-driven conveyors and are typically used for light to medium-duty applications, such as transporting boxes, totes, or small pallets. They are less common than motor-driven (MDR) or chain-driven systems but are valued for their simplicity and low maintenance.

Key Features of Belt-Driven Roller Conveyor Smooth Operation : Belts provide quieter, less jerky movement compared to chains. Low Maintenance : Fewer lubrication needs than chain-driven systems. Versatility : Suitable for straight, curved, or accumulation setups.

Energy Efficiency : Moderate power consumption, especially with modern motors. Applications : Warehousing, distribution, packaging, assembly lines, and light industrial tasks. This is a roller conveyor using round belt to drive conveyor rollers. Key Components of Belt-Driven Roller Conveyor 1.

Conveyor Rollers Support and move loads;driven by belts. Specifications Diameter : 1.5"–2.5" (light/medium-duty);3.5" for heavier loads (rare). Material : Steel (galvanized), stainless steel (food-grade), or plastic-coated. Spacing : 2"–6" centers;loads span 3+ rollers.

Drive Connection : Rollers have grooves or pulleys for belt engagement (e.g., O-ring grooves). 2. Drive Belts Transmit power from motor or drive shaft to rollers. Types O-Ring Belts : Round polyurethane belts, common in line-shaft conveyors, connect rollers to a drive shaft.

Flat Belts : Wide, flat belts under rollers for direct drive (e.g., belt-driven live roller, BDLR). V-Belts : Less common, used for high-torque applications. Specifications O-Ring : 3/16"–1/4" diameter, 10"–24" length (loop). Flat Belt : 4"–12" wide, continuous loop under rollers.

Material : Polyurethane (durable, flexible), rubber (high grip), or PVC (food-grade). Tension : Adjustable via pulleys or tensioners to prevent slippage. 3. Drive System Motor : Electric, typically 1/2–2 HP (110V–480V), drives a shaft or belt pulley.

Drive Shaft (Line-Shaft) : Common in O-ring systems;a rotating shaft runs parallel to rollers, connected by belts. Gearbox : Reduces motor speed, increases torque (e.g., 10:1–20:1 ratio). Controls: Basic : On/off or fixed speed. Advanced : Variable frequency drive (VFD), PLC, or sensors for accumulation.

Speed : 30–150 ft/min (adjustable). 4.Conveyor Frame Function : Supports rollers, belts, and motor;withstands load weight. Material : Steel (powder-coated), aluminum (light-duty), or stainless steel (washdown). Width : Load width + 4"–6" (e.g., 18" box = 24" frame).

Height : 12"–36" (ergonomic for boxes, low-profile for pallets). 5. Side Rails Function : Guide loads, prevent derailment. Types : Fixed (1"–4" high), adjustable, or roller guides for delicate loads. Material : Steel, aluminum, or stainless steel. 6.

Accessories Pulleys : Guide belts, maintain tension (e.g., crowned pulleys for flat belts). Sensors : Enable accumulation or flow control (photoelectric/proximity). Guards : Cover belts or drive shaft for safety. Supports : Legs/stands every 5–10 feet.

This is a roller conveyor system with side guide rails using round belt to drive conveyor rollers. Design Considerations of Belt-Driven Roller Conveyor 1. Load Capacity Light-duty ( 1,000 lbs) : Rare;chain-driven or MDR preferred. Calculate total load per zone (e.g., 5 boxes × 50 lbs = 250 lbs). 2.

Conveyor Layout Straight : Common for transport or accumulation. Curved : Tapered rollers with angled belts or line-shaft adjustments. Accumulation : Zoned belts with clutches or sensors for low-pressure queuing. Incline/Decline : Ensure belt grip and motor torque (e.g., 1 HP for steep angles). 3.

Conveyor Speed Range: 30–150 ft/min (typical: 60–100 ft/min). Adjustable via VFD or motor pulley size. 4. Environment Dry/Indoor : Steel rollers, polyurethane belts. Washdown/Food-Grade : Stainless steel rollers, PVC or food-grade belts. Harsh (Dust, Oil) : Sealed bearings, durable belts (e.g., rubber).

Cold Storage : Low-temperature belts and motors. 5. Belt Tension and Maintenance Tension belts to avoid slippage but prevent overstretching. Design for easy belt replacement (e.g., accessible pulleys, removable guards). Inspect belts for wear or cracking every 3–6 months. 6.

Safety Features Guards for belts and drive shaft to prevent pinch hazards. Emergency stops and overload protection. Side rails (2"–4" high) for load stability. This is a flexilble powered roller conveyor using v-belt to drive conveyor rollers. How to Choose a Belt-Driven Roller Conveyor 1.

Define Application Requirements Load : E.g., 50-lb boxes (18" x 12") or 500-lb small pallets (40" x 32"). Purpose : Transport, accumulation, or merging. Distance : E.g., 20' straight or 15' with 45° curve. 2. Select Roller and Belt Type Conveyor Rollers 1.5"–1.9" for light loads (
