⚙ Overview — Assembly Line Conveyor Sprockets
Assembly line conveyors are the backbone of modern manufacturing, moving components seamlessly between workstations. At the heart of every reliable conveyor chain drive is a high-quality sprocket — the toothed wheel that engages the roller chain and translates motor torque into smooth, continuous linear motion.
At Компания Ever-Power Australia Sprockets Co., Ltd., we manufacture conveyor sprockets specifically rated for the repetitive, high-cycle demands of Australian production lines. Whether your facility assembles automotive parts in Melbourne, electronics in Sydney, or food products in Brisbane, our sprockets deliver consistent engagement, low-noise operation, and extended service intervals that keep your throughput targets on track.
Наш assembly line sprockets are available in ANSI and BS/ISO standards, single through triple strand configurations, and with finished bore, taper bore, or QD bushing hubs — giving you drop-in compatibility with virtually every conveyor drive on the Australian market.

⭐ Performance Advantages
✅ Our Sprockets
• CNC-hobbed teeth with ≤ 0.05 mm runout — silent, vibration-free chain engagement at high line speeds.
• Induction-hardened tooth tips (HRC 45) with tough core — resists wear without brittle fracture.
• 100% dimensionally inspected; full traceability to raw-material heat number.
• Pre-applied anti-rust coating for Australia’s humid coastal shipping conditions.
❌ Inferior Sprockets
• Sand-cast teeth with visible burrs — noisy operation, accelerated chain wear.
• No heat treatment — soft teeth mushroom quickly, causing chain skip.
• Inconsistent bore sizing forces on-site reaming, wasting hours of downtime.
• No corrosion protection; surface rust within weeks in tropical Queensland.
⚙ How Conveyor Sprockets Work
In a typical assembly line conveyor, an electric gearmotor outputs torque to a drive shaft. Mounted on that shaft is the drive sprocket, which meshes with the rollers of a precision roller chain. As the sprocket rotates, its teeth sequentially engage and release the chain links, converting rotational motion into the linear travel of the conveyor belt or slat top chain.
A second idler (tail) sprocket at the opposite end maintains chain tension and guides the return strand. Together, the drive and idler sprockets define the conveyor’s effective length and ensure the chain tracks straight without derailing.
Key locations: Drive sprocket at the motor/gearbox end; idler sprocket at the tensioning/tail end. Purpose: Transmit torque, maintain chain tension, and guarantee consistent conveyor speed for synchronised assembly.

📈 Conveyor Speed Quick-Reference
Estimate your line speed: Line Speed (m/min) = Teeth × Pitch (m) × RPM.
| Зубы | Подача | RPM | m/min |
|---|---|---|---|
| 17 | 1/2″ | 60 | 12.95 |
| 21 | 3/4″ | 45 | 18.00 |
| 25 | 1″ | 30 | 19.05 |
📚 Quick Selection Guide
| Step | What to Determine | How to Find It |
|---|---|---|
| 1 | Chain pitch & standard | Stamped on chain side plate (e.g. “60” or “12B”) |
| 2 | Number of teeth | Count existing teeth or check OEM drawing |
| 3 | Number of strands | Inspect chain: simplex, duplex, or triplex |
| 4 | Bore size and keyway | Measure shaft diameter; note keyway dims |
| 5 | Hub type | Check mounting space; QD preferred for easy maintenance |

🛠 Installation Steps
- Lock-out / Tag-out: Disconnect power per AS/NZS 4024.
- Release Chain Tension: Loosen tail-end take-up bolts.
- Remove Old Sprocket: Loosen set screws, slide bushing off shaft. Clean shaft seat.
- Inspect Shaft: Check for scoring, corrosion, keyway damage. Confirm H7 tolerance.
- Fit New Sprocket: Align keyway, hand-tighten bushing bolts in star pattern.
- Align Sprockets: Straightedge across drive and idler; ≤ 0.5 mm per 300 mm span.
- Tension Chain: Adjust take-up for 2% sag on slack side.
- Torque Set Screws: Per bushing spec; apply thread locker where vibration exists.
- Lubricate: Apply ISO VG 100 chain oil to joints and teeth.
- Test Run: Low speed 5 min, check noise/tracking, ramp to full speed.
🚧 Troubleshooting
Chain skips teeth
Причина: Worn teeth or chain stretch > 3%. Исправить: Замените звездочку и цепь одновременно.
Excessive noise
Причина: Misalignment or poor lubrication. Исправить: Re-align sprockets, re-lubricate.
Uneven tooth wear
Причина: Angular misalignment or shaft deflection. Исправить: Check shaft straightness with dial indicator.
Chain rides high on teeth
Причина: Chain elongation beyond limit. Исправить: Measure over 10 pitches; replace if > 1.5% for critical drives.
Hub loosens on shaft
Причина: Insufficient torque or worn keyway. Исправить: Re-torque or switch to taper-lock bushing.
