3-Stage Gear Motor (2 UDL 1.5kW and 1 R57)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57) is a gear motor assembled from an electric motor (specifically a 3-phase electric motor) combined with a gearbox (specifically a 3-stage gearbox). The output shaft design is compact and can be arranged in multiple directions, allowing easy installation even in limited spaces or complex machinery assemblies. With a 3-stage continuous gear reduction configuration, the motor delivers a slow, stable output speed, precise operation, and is suitable for 24/7 working demands.

Overview design of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57) features a robust design optimized for heavy-duty and continuous operation in high-temperature or dusty environments. Both the motor body and the R57 gearbox are manufactured from solid cast iron or cast aluminum alloy.

Detailed structure of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57) is a gear motor line ranging from 1.1kW to 3.7kW assembled from a 3-phase 1.5kW 2Hp electric motor with a 3-stage gear motor (2 UDL 1.5kW and 1 R57). Its detailed structure is as follows:

Electric motor structure:

• The motor housing is made of cast iron or cast aluminum alloy, offering high rigidity, vibration resistance, and good heat dissipation.
• The surface is powder-coated to prevent oxidation and withstand dusty-humid environments.
• 100% high-temperature resistant copper windings ensure the motor works continuously without overheating.
• The squirrel-cage rotor is precisely dynamically balanced, helping the motor run smoothly, reducing vibration, and increasing bearing lifespan.
• The hardened steel rotor shaft resists wear during heavy-duty operations

Gearbox structure:

• Stage 1 is a mechanical speed variator (UDL): Specifically, a 1.5kW 2Hp mechanical speed variator consisting of a friction disc – cone disc assembly, input – output shafts, and an adjustment knob, allowing stepless speed variation before entering the gearbox.
• Stage 2 is the R57 gearbox, specifically (Heavy Duty R-Series Inline Helical Gear Motor 5.5kW 7.5Hp, Heavy Duty R-Series Inline Helical Gear Motor 7.5kW 10Hp), creating a large gear ratio and high torque for smooth operation.
• Housing, bearings, and lubrication system: Sturdy cast iron/aluminum housing, load-bearing bearings, and lubricating gear oil help reduce friction, dissipate heat, and increase durability.

Specifications of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57) is a transmission system consisting of a 3-phase 1.5kW electric motor, two UDL mechanical speed variators, and an R57 inline helical gearbox. This configuration allows the system to adjust speed flexibly while generating a lower output speed and higher pulling force.

Specifications of the 3-Phase 1.5kW 2HP Electric Motor

The 3-phase 1.5kW 2Hp electric motor provides the driving power for the entire system. The motor is designed with a flange-mounted style, making connection to the mechanical speed variator and gearbox convenient.

Specifications of the 2 UDL 1.5kW 2HP Mechanical Speed Variator

Two UDL mechanical speed variators are connected in series to expand the speed adjustment range. Users can change the output rotation speed to suit the working requirements of each machine type.

Specifications of the R57 Inline Helical Gearbox

The R57 inline helical gearbox is installed at the final stage, responsible for reducing speed and increasing torque before transmitting motion to the working equipment. The gearbox operates stably and helps the system run more efficiently.

Common applications of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57)

• The 3-Stage Gear Motor (2 UDL 1.5kW and 1 R57) is suitable for many industrial fields requiring high torque and slow speed:
• Low-speed conveyor lines
• Chemical stirrers, paste mixers, thick material agitators
• Mixers, turning machines, material incubation machines
• Industrial feeding and dosing equipment
• Food processing, seafood, packaging, wood, and plastic industries
• Mechanical machinery operating long-term with high stability requirements

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

• Step 1 – Connecting the first stage: Place the UDL mechanical speed variator onto the output shaft of the electric motor, rotate gently so the internal couplings automatically fall into position.
• Step 2 – Connecting the second speed control stage: Attach the second UDL unit to the output part of the first UDL unit, ensuring the shaft components mesh accurately with each other.
• Step 3 – Installing the heavy-duty gearbox: Bring the R-Series Inline Helical Gearbox behind the second UDL unit to complete the drive train.
• Step 4 – Finalizing assembly: Check the alignment of the entire system, then install bolts into the flange holes and tighten securely to connect the components together.
