ZQ 500 Gearbox (Size 500) – Output Shaft 85mm | 10 Ton Load Capacity

When it comes to heavy-duty pressing and grinding applications, ZQ 500 Gearbox is indispensable. This gearbox model boasts superior size and power within the ZQ Gearboxes category, specializing in solving the most challenging power transmission problems that aluminum casing gearboxes or medium-duty gearboxes cannot handle.

ZQ 500 Gearbox Technical Specifications (Size 500)

The ZQ 500 is a massive cast iron block with impressive technical specifications. Please carefully review the dimensions below to design an appropriate foundation:

• Center distance (A): 500mm.
• Output shaft diameter (Slow shaft):
  • Cylindrical shaft type (Z): 85mm (Standard 85mm shaft).
  • Spline shaft type (F): 85mm (Gear module 8, number of teeth Z=12 - Commonly used for hoist/crane drum gears).
• Input shaft diameter (Fast shaft):
  • Tapered type: 60mm.
  • Cylindrical type: 55mm.
• Recommended motor power: Best optimized with a Motor 22kW (30HP) or 30kW (40HP) - 6-pole speed (960 RPM) or 4-pole speed (1450 RPM).
• Gear ratio (Ratio): i = 10, 12.5, 16, 20, 25, 31.5, 40, 48.57.
• Weight: ~ 380kg - 420kg (Requires a hoist or crane for relocation).
• Lubricant volume: Approximately 12 - 14 Liters.

Why is ZQ 500 dubbed the “King of Heavy Loads”?

In the 8 to 12-ton load segment, ZQ 500 possesses special structural advantages:

• Module 8 Gears: Extremely large and thick teeth, carburized to a hardness of 62 HRC. This enables ZQ 500 to withstand hundreds of tons of pressure in brick presses and sugarcane presses without chipping teeth.
• 30mm thick Cast Iron Casing: The extremely thick casing walls absorb all vibrations. Even when operating at full capacity, the gearbox remains “rock solid”.
• Heat Dissipation Capability: A large oil reservoir (over 10 liters) helps cool the gears quickly, allowing continuous 24/7 operation.

Practical Applications of ZQ 500

ZQ 500 Gearbox is the heart of heavy industrial production lines:

• Brick Factories: Used for vacuum brick extruders, clay mixers (Requires maximum torque to push clay).
• Sugarcane Mills: Used for large capacity sugarcane crushing rollers (for maximum bagasse extraction).
• Mineral Mining: Hauling coal carts from mine shafts, conveying large rocks uphill.
• Port Cranes: Lifting mechanisms for container gantry cranes, construction tower cranes.

Crucial Considerations when Operating the ZQ 500

• Lubricant: This is the most critical factor. ZQ 500 requires a very large volume of oil (~12-14 Liters). High-viscosity industrial oil (VG 320 or 460) must be used. Absolutely do not use waste oil or grease.
• Couplings: Since the 85mm output shaft transmits very high power, large gear couplings or FCL couplings should be used to prevent coupling pin breakage during overload.
