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

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDX 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), forming a multi-stage transmission system capable of flexible speed customization and high output pulling force. This combination allows the device to operate stably under heavy load requirements while expanding the speed adjustment range that single-stage gearboxes cannot meet.

Overview of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDX 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDX 70) features a solid cast iron or aluminum housing, coated with an electrostatic paint layer to prevent scratches during operation. It creates a multi-stage transmission system with wide speed control capability and strong torque. Thanks to the tight combination structure between stages, the device delivers high transmission efficiency, smooth operation, and excellent performance for various heavy-duty requirements in industrial environments.

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

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDX 70) is a gear motor under 1.1kW, assembled from a 3-phase electric motor 0.8kW 1Hp and a 3-stage gearbox (2 UDL 0.8kW and 1 WPDX 70) with detailed structure as follows:

Electric Motor Structure:

• Motor housing: Cast from cast iron or aluminum alloy, protecting internal components and assisting with heat dissipation.
• Rotor: Installed coaxially with the motor shaft, transmitting rotational movement to the reduction system.
• Stator: Class F insulated copper winding, meeting working requirements at rated load.
• Terminal box: Sealed design, convenient for connecting power sources and protecting terminals from dust.

Gearbox Structure:

• Stage 1 is a mechanical speed variator (UDL): Specifically, the 0.8kW 1Hp mechanical speed variator includes a friction disc – cone disc assembly, input-output shafts, and an adjustment knob, allowing stepless speed changes before entering the gearbox.
• Stage 2 is a 2-stage gearbox: Specifically, the 2-stage UDL 0.8kW – WPDX 70 gearbox consists of a hardened steel worm and a bronze worm gear, creating a large gear ratio and high torque for smooth operation.
• Stage 3 is the WPDX 70 worm gearbox: Reduces output speed and generates torque suitable for the load.
• Bearings and lubrication system: Reduce friction between rotating parts, helping extend equipment lifespan.

Guide on How to Install the Electric Motor with 2 UDL and 1 WPDX

To assemble the electric motor combined with 2 UDL units and 1 WPDX, technical steps must be strictly followed to ensure stable transmission system operation, minimize mechanical losses, and improve operating efficiency.

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

Insert the electric motor shaft into the input of the first UDL variator unit. Check the concentricity between the shaft and the flange, then tighten the bolts in sequence to create a secure connection and limit vibration during operation.

Step 2: Connect the second UDL unit

Connect the output of the first UDL unit to the input of the second UDL unit. Precisely align the mounting positions, check the shaft’s rotational capability, and secure all bolts so the speed control assembly operates stably.

Step 3: Connect to the WPDX gearbox

Install the assembly consisting of the electric motor and two UDL units onto the WPDX gearbox. Ensure the key and shaft engage in the correct position, then tighten the flange bolts. Before powering on, rotate the shaft manually to check for smoothness and detect any deviations early if present.

Combining two UDL variators with the WPDX gearbox creates a 3-stage transmission system capable of flexible speed reduction, increased output torque, and excellent response to applications requiring low speed and high load capacity such as agitators, conveyors, mixers, presses, and other industrial equipment.
