The ZQ 3-Stage Gearbox is one of the essential gearboxes in industrial systems that require maximum traction and ultra-slow speeds. With a more complex structure, this ZQ 3-Stage Speed Reducer involves 3 transmission stages for consecutive speed reduction, achieving the largest transmission ratio in the ZQ series. This is an ideal choice for heavy-duty equipment that requires absolute durability and stable long-term operation.

Advantages of the ZQ 3-Stage Gearbox

• Achieves a very large transmission ratio: Thanks to its three-stage gear drive structure, the ZQ 3-Stage Gearbox provides deep speed reduction, suitable for equipment requiring very low and stable output speeds.
• Sturdy cast iron housing with good impact resistance: The rigid body structure helps reduce vibration during operation and enhances the durability of the equipment.
• High-quality steel gears: The gear system is precisely machined, offering high load capacity and good wear resistance during continuous operation.
• Easy maintenance and periodic inspection: The simple mechanical structure makes oil changes, gear checks, and equipment maintenance much more convenient.
• High service life: When selected with the correct load and maintained periodically, the ZQ 3-Stage Gearbox can operate stably for many years while ensuring transmission efficiency.

Applications of the ZQ 3-Stage Gearbox

• Heavy-duty overhead crane and gantry crane systems: The ZQ 3-Stage Gearbox is commonly used for high-capacity lifting equipment requiring high traction and continuous operation in industrial environments.
• Winches and heavy-duty towing equipment: Thanks to its large transmission ratio and high output torque, the ZQ 3-stage is suitable for winch systems in mining, ports, and construction projects.
• High-capacity industrial crushers: Installed in stone crushers, ore crushers, coal crushers, and material processing equipment requiring strong driving force.
• Cement and building material production lines: The ZQ 3-Stage Gearbox is frequently used for heavy-duty conveyor systems, feeders, and material handling equipment.
• Rolling and pressing equipment in the metallurgical industry: Suitable for steel rolling systems, metal pressing, and machinery requiring high torque during operation.
• Large-capacity mixing systems: Applied in chemical mixing tanks, wastewater treatment, and industrial manufacturing where low rotational speed but high driving force is required.

Below is the price list for several ZQ 3-Stage Gearbox models currently distributed by Thanh Thai Motor for your convenience in referencing and selecting the appropriate product for heavy-duty, low-speed industrial applications.

Criteria for Purchasing a ZQ 3-Stage Gearbox

• Determine the correct transmission ratio needed: The ZQ 3-Stage Gearbox is usually chosen for applications requiring very low output speeds, so accurately determining the operating speed of the equipment is a top priority factor.
• Evaluate the actual load of the system: For equipment such as cranes, crushers, presses, or heavy-duty conveyors, the gearbox should be selected based on the actual operating load rather than just the motor power.
• Check the paired motor power: The motor and gearbox need to be selected synchronously to ensure transmission capability, avoiding underload or overload during use.
• Consider daily working hours: For systems operating continuously for many hours or multiple shifts, prioritize models with high load capacity and greater durability than actual requirements.
• Compare installation dimensions: Before purchasing, check the input shaft, output shaft, base dimensions, and installation space to ensure compatibility with the existing system.

Frequently Asked Questions

What is the output speed when a 1450 rpm motor is paired with a ZQ 3-stage gearbox?

The output speed depends on the transmission ratio of the gearbox. For example, with a 1/50 transmission ratio, the output speed is about 29 rpm, while with a 1/100 transmission ratio, the speed is only about 14 rpm.

Does the ZQ 3-Stage Gearbox require using a high-capacity motor?

No. Choosing motor power depends on the load and operating requirements of the system. There are applications that use a small motor but still need a ZQ 3-stage to achieve a very low output speed.

What parameters need to be checked when replacing an old ZQ gearbox?

You need to check the gearbox model, transmission ratio, output speed, shaft dimensions, mounting position, and current motor power to select the correct replacement product.
