3-Stage Gear Motor (2 UDL 2.2kW And 1 R67)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 R67) is a gear motor assembled from an electric motor-specifically a 3-phase electric motor-combined with a gearbox, specifically a 3-stage gearbox, creating a drive system capable of smooth speed variation while maintaining strong torque. Thanks to the use of two UDL stages, the output speed range is significantly expanded, helping the equipment easily adapt to various operating requirements.

Overview of the 3-stage gear motor (2 UDL 2.2kW and 1 R67)

The 3-stage gear motor (2 UDL 2.2kW and 1 R67) is recognized by its solid cast iron housing and the characteristic shape of the helical gearbox. The R67 design features a strong mechanical style, with a right-angle housing, prominent stiffening ribs, and an inline output shaft, suitable for various drive connection types. This component withstands high loads and significantly increases torque for the system.

The overall design forms a drive assembly with a synchronized, sturdy, and industrial aesthetic appearance, easy to install in various machinery spaces and suitable for production lines requiring flexible speed changes yet high pulling force.

Detailed structure of the 3-stage gear motor (2 UDL 2.2kW and 1 R67)

The 3-stage gear motor (2 UDL 2.2kW and 1 R67) is a gear motor line ranging from 1.1kW to 3.7kW assembled from a 3-phase electric motor 2.2kW 3Hp with a 2-stage UDL 2.2kW – R67 gearbox and a 2.2kW 3Hp mechanical speed variator, with the following detailed structure:

Electric motor structure:

• The housing is cast in one piece from cast iron or aluminum alloy, with cooling ribs running along the body to quickly dissipate heat and protect the internal electrical parts.
• The stator consists of tightly pressed electrical steel laminations wound with copper wire to generate a rotating magnetic field when energized.
• The squirrel-cage rotor is placed inside the stator, directly attached to the motor shaft to convert the magnetic field into mechanical motion.
• The support and cooling system includes load-bearing bearings at both ends of the shaft and an integrated rear cooling fan to maintain smoothness, limit friction, and cool down when the motor operates continuously.

Gearbox structure:

• Stage 1: Mechanical speed variator (UDL): Specifically, the 2.2kW 3Hp motor speed variator intermediate shaft carries larger gears, further reducing speed and increasing torque to meet heavy-duty loads.
• Stage 2: R67 gearbox specifically (R-Series Inline Helical Gearbox 2.2kW 3Hp or R-Series Inline Helical Gearbox 4.0kW 5.5Hp) enclosing the entire transmission assembly and integrating an oil reservoir to maintain continuous lubrication.
• The output shaft is mounted on heavy-duty bearings and uses oil seals to prevent leakage, ensuring stable torque transmission and durable operation over a long period.
• The input shaft drives the small-large gear set (or worm gear set depending on the series), creating an initial reduction step and increasing the transmission force to the intermediate shaft.

Technical specifications of the 3-stage gear motor (2 UDL 2.2kW and 1 R67)

The 3-stage gear motor (2 UDL 2.2kW and 1 R67) consists of a 3-phase 2.2kW electric motor, two UDL mechanical speed variators, and an R-Series Inline Helical Gearbox R67. This combination helps flexibly change speed, reduce output speed to a lower level, and increase pulling force for the system. The device is suitable for machinery requiring frequent speed adjustment during operation.

Technical specifications of the 3-phase electric motor 2.2kW 3Hp

The 3-phase electric motor 2.2kW 3Hp is the component that generates movement for the entire system. The motor is designed with a flange mounting style, convenient for installation with the mechanical speed variator and gearbox.

Technical specifications of the 2 UDL 2.2kW 3Hp mechanical speed variator

Two UDL mechanical speed variators are installed in series to enhance speed adjustment capability. Users can easily change the output speed according to their usage needs.

Technical specifications of the R67 inline helical gearbox

The R67 inline helical gearbox is responsible for reducing rotational speed from the mechanical speed variator and increasing output torque. The gearbox operates stably, helping the system run efficiently and continuously for a long time.

Applications of the 3-stage gear motor (2 UDL 2.2kW and 1 R67)

Thanks to its flexible speed adjustment capability and strong pulling force, the 3-stage gear motor well meets various modern production systems.

• Used for industrial stirrers and mixers, where speed must be continuously changed while maintaining stable torque.
• Applied in heavy-duty conveyors, helping to transport materials evenly, stably, and safely.
• Installed in food – chemical – agricultural processing lines requiring low speed and durable operation.
• Suitable for equipment requiring precise speed adjustment, such as dosing machines, blending machines, or material handling systems.

Instructions for installing an electric motor with 2 UDL mechanical speed variators and 1 R-Series inline helical gearbox

• Step 1: Fit the flange of the first UDL speed variator onto the output shaft of the electric motor, ensuring the internal transmission parts mesh tightly together.
• Step 2: Attach the second UDL speed variator to the output of the previously installed UDL unit, aligning the shaft and installation position synchronously.
• Step 3: Install the R-Series inline helical gearbox at the final position, directly connecting to the output shaft of the second UDL speed variator to complete the drive train.
• Step 4: Proceed to install screws into all waiting holes on the flanges of the components, then use tools to tighten them to secure the entire system into a solid connected block.
