3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDA 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDA 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 with an angled output shaft for easier installation in systems with complex structures or limited space. The product is suitable for applications requiring gradual, stable, and precise movement.

General Design of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDA 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDA 70) features a design that ensures step-by-step speed reduction, helping to avoid load shock and ensure continuous torque, bringing great flexibility in operation. The gearbox housing is thick and sturdy, effectively reducing vibration. The equipment assembly is firmly mounted on a base, ensuring stable operation in industrial environments.

Detailed Structure of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDA 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDA 70) belongs to the group of gear motors ranging from 0.4kW to 2.2kW, assembled from a 0.8kW 1Hp 3-phase electric motor and a 3-stage gearbox assembly consisting of two UDL units and one WPDA 70 gearbox.

Electric Motor Structure

• Motor housing: Machined from cast iron or aluminum alloy, increasing rigidity and supporting heat dissipation during operation.
• Rotor: Machined concentrically with the drive shaft, helping transfer torque to the gearbox stably.
• Stator: Wound with Class F insulated copper wire, ensuring the ability to work at rated load for a long time.
• Terminal box: Conveniently arranged wiring bridge, with dust-tight and moisture-proof seals according to IP55 standards.
• Motor rear: Includes a cooling fan and protective grille, maintaining a stable temperature for the motor during operation.

Gearbox Structure

• Stage 1 is the mechanical speed variator (UDL): The 0.8kW 1Hp motor speed controller uses a friction disc mechanism and adjustment lever to change the rotational speed steplessly.
• Stage 2 is the intermediate gearbox: Combined with the UDL unit to further reduce speed and transmit torque to the final stage.
• Stage 3 is the WPDA 70 worm gearbox: Completes the speed reduction process, creating low output speed and high torque.
• Bearing and lubrication system: Heavy-duty bearings combined with specialized lubricating oil help reduce friction and increase the service life of the transmission assembly.

• Conveyor belts for transporting packaging, components, or products in production lines.
• Solution agitators, chemical mixing tanks, and small-capacity material mixing systems.
• Coil pulling equipment, feeding mechanisms, and automatic packaging machines.
• Pellet presses, rubber calenders, drying conveyors, and systems requiring continuous speed adjustment.

Instructions on How to Install the Electric Motor with 2 UDL and 1 WPDA

To install the electric motor with 2 UDL speed variators and 1 WPDA gearbox, each stage must be executed according to technical standards to ensure that the transmission components fit precisely, operate stably, and achieve high reduction efficiency.

Step 1: Couple the electric motor with the first UDL

Place the output shaft of the electric motor into the input of the first UDL unit. Align the shaft and flange concentrically, then tighten the bolts in order to make the assembly secure and reduce vibration during operation.

Step 2: Connect the second UDL

Connect the output of the first UDL unit to the input of the second UDL unit. Check the mesh of the shaft, adjust if necessary, and then secure the connecting bolts so that the transmission system works synchronously.

Step 3: Mount the transmission assembly to the WPDA gearbox

Bring the entire assembly of the electric motor and the two UDL units into the WPDA gearbox. Align the keyway, flange, and shaft in the correct positions, then evenly tighten the bolts to complete the assembly. Finally, manually rotate the shaft to check smoothness and transmission capability before powering on.

The coordination between the two UDL speed variators and the WPDA gearbox creates a 3-stage transmission system capable of flexible speed reduction, increasing output torque, and effectively meeting the requirements of low-speed equipment such as agitators, mixers, conveyors, presses, and many other industrial applications.
