FAQ

ZQ Gear Reducer FAQ (English Version)

 
(Industrial Heavy-Duty Helical Gear Reducer for Cranes, Mining & Conveyors)

Q1: What are the main applications of ZQ reducers?

 
ZQ reducers excel in heavy-duty, low-speed applications with frequent starts/stops, including:
 
  • Cranes & Hoists (e.g., overhead cranes, winches)
  • Mining Machinery (conveyors, crushers, bucket elevators)
  • Chemical Mixers (agitators, reactors)
  • Textile/Steel Equipment (spinning machines, rolling mills)
 
Key specs:
 
  • Max torque: 8,000~250,000 N·m (9 sizes, center distance 100~750mm)
  • Speed ratio: 8.23:1~48.57:1 (9 standard ratios, ZQH model for 10% higher efficiency)
  • Operates at ≤1500 RPM input, ≤10m/s gear circumferential speed (14m/s for ZQH).
 
Pro Tip: ZQH (arc-tooth helical) models offer 30% longer lifespan than standard ZQ in loads (e.g., mining crushers).

Q2: How to select the right ZQ reducer model?

 
Step 1: Determine torque & speed
 
  • Calculate required torque: T = 9550 × P / n × safety factor (1.5~2.5x for ).
  • Example: A 10t crane needs 500N·m torque → Choose ZQ350 (rated torque 630N·m).
 
Step 2: Choose installation type
 
  • 9 mounting styles: Foot-mounted (ZQ), flange-mounted (ZQF), hollow shaft (ZQK), etc.
  • Output shaft options: Cylindrical (Z-type), gear-coupled (CA/C-type), or flange (F-type).
 
Step 3: Environmental factors
 
  • IP54 standard (IP65 optional for wet/dusty sites like quarries).
  • -40°C~+40°C operating temp; use low-viscosity oil (e.g., ISO VG 150) for <0°C.
 
Tool: Free CAD drawings & torque calculators on .

Q3: What maintenance is required for new ZQ reducers?

 
Break-in period (200~300 hours):
 
  • First oil change: After 200h (critical to remove metal particles), then every 5,000h or 1 year.
  • Oil level check: Maintain oil at the midpoint of the sight glass (HJ40-50 oil or ISO 68 gear oil).
  • Wear inspection: Allow ≤20% tooth surface scuffing in the first month; polish with a stone if ≥30% wear.
 
Long-term tips:
 
  • Use magnetic drain plugs to catch metal debris.
  • For 24/7 operation (e.g., port conveyors), install an oil cooler to reduce temperature by 15~20ºC.

Q4: Why is my ZQ reducer overheating or noisy?

 
Overheating (>80ºC):
 
  •  Under-lubrication: Check oil level; add 0.5~1L if low.
  •  Overload: Reduce load to <90% rated capacity; add a fan for continuous duty.
  •  Oil degradation: Replace if oil turns black/viscous (normal color: amber).
 
Noises/Vibrations:
 
  •  Gear wear: Replace gears if backlash >2mm (ZQ350) or pitting >15% tooth area.
  •  Bearing failure: Replace bearings  if clicking sounds occur.
  •  Misalignment: Re-align couplings to ≤0.1mm offset (use laser alignment tool for precision).
 
Emergency stop: If oil leaks from seals (common after 5~8 years), shut down immediately. Replace oil seals (NBR material for ) and clean housing.

Q5: Can ZQ reducers be customized for special needs?

 
Yes! Common customizations:
 
  • Explosion-proof: ATEX/IECEx for gas/dust environments (e.g., coal mines).
  • Stainless steel: 316SS housing for corrosive liquids (chemical plants).
  • High-speed: Modified helical gears for 18m/s circumferential speed (special conveyor systems).
  • Mounting kits: Custom flanges/output shafts for OEM machinery (e.g., textile rollers).
 
Lead time: 2~4 weeks for standard mods; 6~8 weeks for full custom designs.
