3-Stage Gearbox (2 UDL 0.8kW And 1 WPDO 70)

The 3-Stage Gearbox (2 UDL 0.8kW And 1 WPDO 70) is a gearbox line combined from a mechanical speed variator (UDL) and a 2-stage gearbox to form a 3-stage gearbox with deep deceleration efficiency and wide speed regulation capabilities, helping the system operate stably at various speed modes, generating high torque and low yet stable speed at the final stage, meeting the demands of equipment requiring large pulling force during long-term operation.

Overview of the 3-Stage Gearbox (2 UDL 0.8kW And 1 WPDO 70)

The 3-Stage Gearbox (2 UDL 0.8kW And 1 WPDO 70) is manufactured according to industrial mechanical standards, ensuring high durability and stable operation. The two UDL stages are directly linked, expanding the speed adjustment range and increasing operational accuracy. The WPDO 70 is made of aluminum alloy and cast iron, ensuring rigidity, fast heat dissipation, and good load-bearing capacity. The industrial green powder-coated surface helps the device resist rust, limit oxidation, and increase lifespan when working in humid or dusty conditions. The coaxial design allows for easy installation, compatible with various electric motor lines. The optimized structure helps reduce vibration, minimize noise, and enhance stability for the entire system.

Detailed structure of the 3-stage gearbox (2 UDL and 1 WPDO)

The 3-stage gearbox (2 UDL 0.37kW and 1 WPDO 70) consists of a 0.8kW 1Hp motor speed controller combined with a 2-stage UDL 0.8kW – WPDO 70 gearbox to form a compact and flexible 3-stage drive system.

Structure of the mechanical speed variator:

• Friction disc – cone disc assembly: Changes the working radius to create stepless output speed.
• Input shaft – output shaft: The input shaft receives force from the motor, and the output shaft transmits the modified speed.
• Speed adjustment mechanism: Rotary knob / adjustment lever changes the pressure force of the speed-adjusting discs for fast or slow speed.
• Housing & bearings: Cast iron/aluminum housing protects the mechanism; bearings and oil seals ensure smooth and durable operation.

2-stage UDL 0.8kW – WPDO 70 gearbox:

• Stage 1 – UDL 0.8kW unit: Stepless speed adjustment via friction mechanism, providing a flexible speed range.
• Stage 2 – WPDO 70 worm gearbox consisting of a steel worm and bronze worm wheel to create a large gear ratio and high torque.
• WPDO gearbox input and output shafts: The input shaft receives the reduced speed from the UDL; the output shaft delivers high torque and smooth rotation.
• Cast iron housing and lubrication system: Sturdy cast iron housing, gear oil lubrication helps reduce friction and increase lifespan.

Technical specifications of the 3-Stage Gearbox (2 UDL 0.8kW And 1 WPDO 70)

For the machinery system to operate smoothly and precisely meet the required pulling force, understanding the dimensional indices and gear ratios of the device is extremely important.

Technical specifications of the UDL 0.8kW motor speed controller

Acting as the input speed control mechanism of the system, the UDL 0.8kW mechanical speed variator features a flexible gear ratio range and a standard B5 flange design for a solid coaxial connection. Below are the detailed dimensional specifications and shaft standards of this device:

Technical specifications of WPDO 70 gearbox

Located at the final drive stage, the WPDO 70 worm gearbox plays the role of eliminating speed, increasing maximum torque, and bearing the main load for the entire operating line.

Applications of the 3-stage gearbox (2 UDL 0.8kW and 1 WPDO 70)

This 3-stage gearbox is connected to an electric motor, more specifically a 3-Phase Electric Motor 0.8kW 1Hp, which has applications in industries such:

• Conveyor systems: Used for sorting goods in production
• Agitator and mixer systems: Applied in small-capacity grinders.
• Packaging systems: Applied in labeling packaging machines and automated lines

How to assemble the WPDO gearbox and 2 UDL mechanical speed variators to form a 3-stage gearbox

The assembly of the 3-stage gearbox combination requires meticulousness to ensure absolute concentricity (coaxiality), helping the system operate smoothly, transmit power well, and limit wear and tear.

• Assembling the two UDL mechanical speed variators together: Insert the output shaft of the first UDL variator (the motor will be attached to the other end of this unit) directly into the hollow shaft bore of the second UDL variator.
• Assembling the 2-UDL assembly into the WPDO 70 gearbox: After successfully connecting the 2-UDL assembly, proceed to insert the output shaft part of the second UDL unit into the hollow shaft bore of the WPDO 70 gearbox. Align the flange of the UDL to fit snugly with the flange of the WPDO 70.

The combination of the two UDL 0.8kW mechanical speed variators and the WPDO 70 worm gearbox has created a perfect 3-stage gearbox solution for production needs requiring high torque and flexible speed adjustment capabilities.
