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

The 3-stage gear motor (2 UDL 0.8kW and 1 WPDO 70) is a gear motor assembled from an electric motor, specifically a 3-phase electric motor combined with a gearbox, specifically a 3-stage gearbox. Thanks to its cross-angled output shaft design, the device is easy to arrange in confined installation locations or complex machinery structures. This gear motor assembly is suitable for production lines requiring slow speeds, stable movement, and high precision.

Overview of the 3-stage gear motor (2 UDL 0.8kW and 1 WPDO 70)

The 3-stage gear motor (2 UDL 0.8kW and 1 WPDO 70) is completed with a robust design, high durability, and stable operation even in heavy-duty industrial environments. The three-stage reduction system is arranged in successive reduction stages, minimizing load shock while maintaining a strong and stable output torque throughout operation. A prominent highlight in the design of this transmission set is its outer protective housing. The gearbox housing and motor housing are made of cast iron or monolithic cast aluminum alloy, depending on the model and size.

Structure of the 3-stage gear motor (2 UDL 0.8kW and 1 WPDO 70)

The 3-stage gear motor (2 UDL 0.8kW and 1 WPDO 70) is a gear motor under 1.1kW formed by combining a 3-phase electric motor 0.8kW 1Hp with a 3-stage gearbox (2 UDL 0.8kW and 1 WPDO 70), creating a multi-stage transmission assembly that operates stably and flexibly.

Electric motor structure:

• Friction disc – variable speed cone disc assembly: Consists of friction discs pressed against each other, changing the contact radius to create an infinitely variable speed range.
• Input and output shafts: The input shaft connects directly to the motor, the output shaft receives the varied speed; both use ball bearings and oil seals for smooth operation.
• Speed adjustment unit: A dial or handwheel on the UDL body used to change the pressing force of the discs → adjust fast/slow without stopping the machine.
• Housing & lubrication system: Cast iron/cast aluminum housing protects the entire mechanism; lubricating oil/grease helps reduce friction, working stably and more durably.

Gearbox structure:

• Stage 1 is the mechanical speed variator (UDL): Specifically, the 0.8kW 1Hp motor mechanical speed variator consisting of the friction disc – cone disc assembly, input – output shafts, and adjustment knob, allowing infinitely variable speed adjustment before entering the gearbox.
• Stage 2 is the 2-stage gearbox: Specifically, the 2-stage UDL 0.8kW – WPDO 70 gearbox creates a large transmission ratio and high torque, operating smoothly.
• Housing, ball bearings, and lubrication system: Sturdy cast iron/cast aluminum housing, load-bearing ball bearings, and gearbox lubricating oil help reduce friction, dissipate heat, and increase durability.

Guide on how to assemble the electric motor with 2 UDL and 1 WPDO

To form a 3-stage gear motor using 2 UDL and 1 WPDO, assembly must follow the correct technical sequence to ensure transmission parts coordinate precisely, operate smoothly, and achieve optimal reduction efficiency.

Step 1: Install the electric motor with the first UDL unit

Insert the shaft of the electric motor into the input of the first UDL speed variator. Adjust so that the shaft and flange are centered, then evenly tighten the bolts to create a secure connection, helping to limit vibration and enhance working stability.

Step 2: Combine the second UDL unit

Continue connecting the output of the first UDL to the input of the second UDL. After the components are completely fitted together, proceed to secure the connection points and check the rotation of the shaft to ensure the transmission system operates smoothly.

Step 3: Install the transmission assembly into the WPDO gearbox

Place the electric motor assembly and two UDL units into the WPDO gearbox. Align the keyway, shaft, and flange in position before tightening all bolts. Upon completion, recheck joints and test-rotate the shaft to confirm the system operates smoothly before energizing.

The combination of two UDL speed variators and the WPDO gearbox creates a 3-stage transmission system capable of effective speed reduction, maintaining stable torque, and suitable for various applications requiring low rotational speeds such as agitators, conveyors, mixers, presses, and industrial mechanical equipment.
