3-Stage Gear Motor (2 UDL 0.8kW and 1 R47)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 R47) is a gear motor assembled from an electric motor, specifically a 3-phase electric motor, combined with a gearbox, specifically a 3-stage gearbox featuring a parallel shaft gearbox renowned for its durability and powerful power transmission. Thanks to its compact offset output shaft design, the device can be easily arranged in tight, restricted installation positions or complex mechanical assemblies. This is an ideal gear motor for systems requiring slow speeds, precise movement, and long-term stable operation.

General design of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 R47)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 R47) possesses a sturdy design, optimized for continuous operation in heavy-duty environments. The three-stage reduction system is arranged sequentially from mechanical speed variator → intermediate reduction → main reduction, ensuring that the speed is reduced gradually, minimizing load shock and maintaining stable torque throughout operation. The motor housing and gearbox casing are made of solid cast iron or cast aluminum alloy, providing high rigidity and excellent load-bearing capacity. This material supports rapid heat dissipation, reduces vibration, and resists corrosion, helping to extend equipment lifespan even when working in harsh industrial environments.

Detailed structure of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 R47)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 R47) is a gear motor under 1.1kW assembled from a 3-phase electric motor 0.8kW 1Hp with a 3-stage gearbox (2 UDL 0.8kW and 1 R47). It has the following detailed structure:

Electric motor structure:

• Motor housing made of cast iron or cast aluminum alloy, offering high rigidity, vibration resistance, and good heat dissipation.
• Surface coated with electrostatic paint to prevent oxidation and withstand dust-humid environments.
• 100% copper windings resistant to high temperatures, ensuring the motor works continuously without overheating.
• Squirrel-cage rotor dynamically balanced accurately, helping the motor run smoothly, reducing vibration, and increasing bearing life.
• Hardened steel rotor shaft, resistant to wear during heavy-duty work

Gearbox structure:

• Stage 1 is a mechanical speed variator (UDL): Specifically, a mechanical speed variator consisting of friction disc – cone disc assembly, input – output shafts, and adjustment knob, allowing stepless speed change before entering the gearbox.
• Stage 2 is the R47 gearbox, specifically the Heavy Duty R-Series Inline Helical Gear Motor 2.2kW 3Hp, Heavy Duty R-Series Inline Helical Gear Motor 4.0kW 5.5Hp thanks to its special structure with the motor and gearbox featuring a sturdy, robust casing and high lifespan.
• Housing, bearings, and lubrication system: Sturdy cast iron/aluminum housing, heavy-duty bearings, and lubricating gear oil to help reduce friction, dissipate heat, and increase durability.

• Production lines requiring strict speed control and stable torque.
• Slow-operating conveyor systems, chemical mixers, material blending machines.
• Mechanical machinery and industrial equipment requiring continuous operation in harsh environments.
• Food, packaging, wood processing, and plastics industries where smooth, even, and precise movement is needed.
• Dosing or feeding systems requiring extremely low speeds but large torque.

Guide on installing an electric motor with 2 UDL mechanical speed variators and 1 R-Series Inline Helical Gearbox

• Step 1 – Install the electric motor: Place the UDL speed variator onto the flange of the electric motor, adjusting so that the motor shaft fits completely into the shaft hole of the speed variator.
• Step 2 – Couple the speed variator: Use the second UDL unit to mount onto the output of the first UDL unit currently attached to the motor, ensuring the connection is secure and gap-free.
• Step 3 – Attach the reduction unit: Continue bringing the R-series inline helical gearbox close against the second UDL unit; this is the final step in installing the main components.
• Step 4 – Secure the connection: Finally, use screws to tightly fasten the flanges at all 3 connection points so that the entire assembly does not vibrate or loosen during operation.
