Product Description

Product Description

Fa Series Parallel-Shaft Helical Gear Motor Reducer

 

The Fa Series delivers compact, high-efficiency power transmission for industrial machinery. Its parallel-shaft helical design slashes noise to ≤65dB (20% quieter than worm gears) while achieving 92-96% efficiency-ideal for 24/7 operations. Built with precision-machined cast steel housings (IP65-rated for dust/water resistance), it withstands shocks up to 2x rated torque in conveyor, mixer, and hoist applications.

 

Key advantages:
 Space-saving: 30% smaller than comparable bevel gear units, fits tight layouts
 Wide ratios: 5-200:1 options pair with 0.18-75kW motors for torque up to 2,800N·m
 Low maintenance: Self-lubricating system + anti-wear alloy gears enable 10,000+ hours of duty cycle
 Versatile mounting: Foot/flange/shaft-mount variants adapt to any machinery

 

Typical uses include logistics conveyor belts (reducing energy by 15% vs. old models), food processing mixers (quiet operation for cleanrooms), and wastewater pumps (IP65 protection in wet environments). Backed by a 3-year warranty, the Fa Series cuts downtime while delivering 15% longer lifespan than standard helical reducers.

 

(Specs: Weight 8-120kg | Temp range -10°C to +40°C | ISO 6336 compliant)

 

Ideal for engineers seeking reliable, efficient drives-no compromise on performance or space.

FAQ

Common Questions & Answers for Industrial Drives

1. How do I choose the right reducer for my application?

 

Start by calculating torque requirements (T = (F × R)/η), where F = load force, R = radius, and η = efficiency (85-95% for gear reducers). Match speed reduction ratio (i = input speed/output speed) to your system's needs. Consider duty cycle (intermittent/continuous), environment (dust, temperature), and mounting type (foot-mounted, flange, shaft).

2. Why is alignment critical during installation?

 

Misalignment (≥0.1mm) causes excessive wear, noise, and premature failure. Use laser alignment tools or dial indicators to ensure the motor-reducer shaft and driven equipment are concentric. Flexible couplings can absorb minor misalignments but never replace proper alignment.

3. How often should I lubricate my reducer?

 

Lubrication intervals depend on type:

 

• Helical/Bevel reducers: Every 12-24 months (or 2000-4000 hours) with ISO 220-320 oil.
• Worm reducers: Every 6-12 months (grease-lubricated models may require re-greasing every 1000 hours).
  Check oil levels monthly-overfilling causes heat, underfilling leads to metal-to-metal contact.

4. My reducer is noisy-what's wrong?

 

Common causes:

 

• Wear: Damaged teeth (replace gears).
• Lubrication issues: Dirty or degraded oil (flush and refill).
• Loose mounts: Tighten bolts or add vibration dampeners.
• Misalignment: Re-align shafts (see Q2).

5. Can I use a reducer in reverse (output as input)?

 

Most reducers are designed for one-way operation. Reversing may void warranties and cause backdriving (if not ing). Check the manual-worm reducers are often ing (prevent backdriving), while helical reducers may allow reverse with torque derating.

6. How to troubleshoot overheating?

 

• Overload: Reduce load or upgrade to a higher torque model.
• Blocked vents: Clean dust/fibers from cooling fins.
• Low lubrication: Top up oil (ensure correct viscosity for ambient temp).
• High ambient temp: Use a fan or select a reducer rated for +40°C environments.

7. What's the lifespan of a reducer?

 

With proper maintenance, 10-15 years is typical. Factors affecting longevity:

 

• Continuous vs. intermittent operation.
• Shock loads (limit to 2× rated torque).
• Compliance with ISO 13281 (balance quality) and ISO 6336 (gear strength).

8. Can I repair a damaged reducer, or should I replace it?

 

Minor issues (e.g., seal leaks, bearing replacement) are repairable. Major damage (cracked housing, broken gears) usually requires replacement-costly repairs often exceed the price of a new unit. Always consult the manufacturer for warranty eligibility.

9. Do reducers require braking systems?

 

If your application needs rapid stops or holds loads, add a brake (motor-mounted or external). Worm reducers with ing can hold static loads but may not provide dynamic braking.

10. How to optimize energy efficiency?

 

• Choose helical or planetary reducers (90-98% efficiency vs. 60-80% for worm gears).
• Match reducer ratio to actual load (avoid oversized units).
• Use synthetic lubricants for lower friction at high temps.
