3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80)

The 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80) is a gearbox line combined by a mechanical speed variator (UDL) and a 2-stage gearbox to form a 3-stage gearbox, creating a multi-stage drive system with deep reduction capability and large torque, helping equipment operate smoothly in various load modes, running quietly and reducing noise and vibration effectively. Thanks to its sturdy structure and wide gear ratio, the product is suitable for industrial applications requiring low speed but stable traction such as conveyors, mixers, agitators, and packaging lines.

Overall Design of the 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80)

Externally, the 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80) is designed as a robust block, using a cast iron or die-cast aluminum housing to ensure durability and reduce vibration during operation. The input shaft, output shaft, and mounting flange positions are scientifically arranged, supporting fast installation in various machine spaces. The oil seal, bearing, and heat dissipation slots are integrated to ensure good heat dissipation, smooth operation, and long-term durability for the entire drive assembly.

Detailed Structure of the 3-Stage Gearbox (2 UDL and 1 WPDO)

The 3-stage 2 UDL 1.5kW – WPDO 80 gearbox consists of a 1.5kW 2Hp motor speed variator combined with a 2-stage UDL 1.5kW – WPDO 80 gearbox to form a compact and flexible 3-stage drive system with the following structure:

Structure of the speed variator:

• Variable disk assembly: Two conical disks change distance, creating different gear ratios to adjust speed infinitely.
• Dual drive shaft: The input shaft receives torque from the motor, and the output shaft outputs the adjusted speed stably and linearly.
• Mechanical adjuster: A handwheel or control lever acts on the disk clamping force, allowing quick speed increase and decrease.
• Housing & shaft support system: Metal housing protects the mechanism; bearings and oil seals help smooth movement, reduce friction, and increase durability.

Structure of the UDL 1.5kW – WPDO 80 2-stage gearbox:

• Stage 1: The UDL mechanical speed variator takes charge of changing speed via a mechanical adjustment knob.
• Stage 2: Worm gearbox, specifically the WPDO 80 worm gearbox, internally comprising a hardened steel worm meshing with an alloy worm wheel, creating high torque and smooth transmission.
• Drive shaft assembly: Including the input shaft, intermediate shaft, and output shaft, supported by heavy-duty bearings to help the two-stage mechanism operate synchronously, reduce vibration, and optimize transmission accuracy.
• Housing & lubrication system: One-piece cast iron housing protects all internal parts; oil seals and oil chambers help maintain continuous lubrication, minimize friction, and increase equipment lifespan.

Technical Specifications of the 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80)

To ensure precise selection and installation space calculation for your machinery line, understanding the technical specifications of this drive assembly is extremely important. Below are the detailed specifications and dimensions broken down by each equipment assembly comprising this 3-stage reduction system.

Technical Specifications of the UDL 1.5kW Motor Speed Variator

Acting as the input drive stage (stage 1 and stage 2) responsible for variable speed changes, the UDL 1.5kW mechanical speed variator possesses a flexible gear ratio range and B5 flange standard for easy synchronization. Let’s review the detailed connection dimensions of this device:

Technical Specifications of the WPDO 80 Worm Gearbox

As the final drive stage (stage 3) that directly receives torque and determines the load pulling force of the entire system, the WPDO size 80 gearbox is designed with a sturdy housing frame.

Applications of the 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80)

This 3-stage gearbox is connected to an electric motor, more specifically a 3-phase electric motor – 3-phase electric motor 1.5kW 2Hp, with applications in industrial sectors such as:

• Medium-load crushers and presses: The WPDO stage bears loads well, helping generate strong traction and deep reduction for continuously working equipment.
• Automation applications: Supporting flexible speed adjustment, helping stable operation in automated mechanisms requiring high precision.
• Industrial conveyor systems: Allowing speed adjustment according to each production stage, operating smoothly and stably.
• Packaging lines: Ensuring precise movement, supporting packaging, pressing, and labeling steps at a stable speed.

How to Install the WPDO Gearbox and 2 UDL Mechanical Speed Variators to Form a 3-Stage Gearbox

Below are the standard technical operation steps to assemble this WPDO gearbox and 2 UDL mechanical speed variator assembly:

Step 1: Connect the 2 mechanical speed variators (UDL) together

• Insert the key into the keyway on the shaft of UDL 1.
• Carefully align the keyway, then slowly push the positive shaft of UDL 1 into the negative shaft hole (input flange) of the second UDL unit (UDL 2).
• Note: Use a rubber mallet to gently tap around the flange so that the two parts fit tightly together. Absolutely do not use an iron hammer with strong force because it can crack the flange or damage the internal bearing.

Step 2: Install the 2-UDL assembly into the WPDO 80 gearbox

• At this point, you have an equipment assembly consisting of 2 UDLs connected together. Continue to take the key and install it on the positive shaft of UDL 2.
• Insert the positive shaft of UDL 2 into the negative shaft hole on the flange of the WPDO 80 worm gearbox.
• Gently rotate the flange so that the bolt holes are coaxial with each other. Proceed to install bolts and tighten them diagonally, ensuring that the entire system forms a seamless, sturdy block without warping or flange gaps.

The 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDO 80) is an optimal drive solution for industrial systems requiring speed flexibility and high traction. With a structure combined from a durable UDL mechanical speed variator and a precise WPDO 80 worm gearbox, the device not only operates smoothly, reducing noise and vibration, but also ensures outstanding durability in production lines.
