2-Stage Gearboxes, also known as 2-stage speed reducer, is a mechanical transmission device that uses two gears to reduce the input rotation speed and simultaneously increase the output torque. Thanks to the two-stage design, this device is capable of creating a larger transmission ratio than a 1-Stage Gearboxes, thereby helping the system operate stably in applications requiring high traction and large loads.
When this gearboxes (speed reducer) is combined with an electric motor, it forms a geared motor ideal for industrial production lines, conveyor systems, crushers, mixers, and many other mechanical equipment.
Types of 2-Stage Gearboxes
Cycloidal gearboxes uses the Cycloid transmission principle, which helps to reduce speed effectively and achieve a large transmission ratio. The Cycloidal 2-Stage Gearboxes offers advantages such as compact size, high load capacity and outstanding durability. This type of gearbox is used in industrial machinery that requires high precision and stable operation.
ZQ 2-Stage Gearboxes
ZQ gearboxes is a type of reducer that uses expanded helical gears, which helps increase the transmission ratio and withstand loads well. The advantages of the ZQ reducer are its simple structure, easy maintenance and reasonable cost. This type of reducer is often used in light industrial systems such as agitators, mixers, and small conveyors.
2-Stage Mechanical Speed Variator
A mechanical speed control is a type of gearbox that can adjust the output speed by changing the transmission ratio. The advantage of the mechanical speed variator 2-stage is its flexible speed control, which helps optimize the performance of the machine. This type of gearbox is used in systems that require continuous speed regulation, such as rolling mills or tractors.
F-Series 2-Stage Parallel Shaft Helical Gearbox
F-Series Parallel Shaft Helical Gearbox has a parallel input and output shaft design, which saves installation space while maintaining high transmission efficiency. The advantages of this gearbox are smooth operation and easy connection with other equipment. This gearbox is often used in conveyor systems and lifting machines.
K-Series 2-Stage Helical Bevel Gearbox
K-Series Helical Bevel Gearbox has a design of right angle input and output shafts, which helps to change the direction of transmission. The advantage of this type of gearbox is its high load capacity and stable operation. This type is often used in construction machinery and concrete mixer systems.
S-Series 2-Stage Helical Worm Gearbox
S-Series Helical Worm Gearbox has a similar design to the K type but adds an intermediate shaft to increase the transmission ratio and torque. The advantage of this type of reducer is its ability to meet strict requirements for performance and reliability. This reducer is suitable for heavy industrial machinery.
R-Series 2-Stage Inline Helical Gearbox
R-Series Inline Helical Gearbox is equipped with an intermediate shaft to increase the transmission ratio and output torque. With a straight shaft design, this reducer maintains a compact size and is easy to install in limited space. The advantage of the 2-stage R straight shaft reducer is its stable and efficient operation, especially in continuous heavy load applications.
