Heavy Duty R-Series Inline Helical Gear Motor 2.2kW 3Hp

Heavy Duty R-Series Inline Helical Gear Motor 2.2kW 3Hp is a transmission device widely applied in heavy industrial machinery systems. With durable operating capability, a power of 2.2kW (equivalent to 3Hp), heavy duty gear motors help transmit force powerfully, stably, and efficiently save electricity. The R-series inline gear motor is an ideal choice for many high-intensity production lines.

Overview of Heavy Duty R-Series Inline Helical Gear Motor 2.2kW 3Hp

Electric motor

• Material: Housing cast from pressure-resistant cast iron, coated externally with a durable electrostatic paint layer to prevent oxidation in humid environments. The cooling fan system is densely arranged around the body to provide rapid cooling, supporting the motor to operate stably over long periods.
• Function: Provides stable rotational torque for small and medium-scale drive equipment. The motor is designed to withstand continuous duty cycles, ensuring the current remains at a stable threshold and optimizing power consumption.

Gearbox

• Material: Thick cast iron gearbox housing with high impact resistance and high deformation resistance under severe vibrations. The gear system is manufactured from heavy-duty alloy steel, with tooth surfaces treated with carburization to increase mechanical durability and prevent wear and flaking.
• Function: Converts input speed from the motor into output rotation with stronger pulling force. With a concentric design, the gearbox allows mechanical energy transmission to occur directly and accurately, saving installation space and increasing work efficiency for the entire system.

Internal Structure of the R-Series Inline Gear Motor

The structure of a gear motor is a combination of an electric motor and a gearbox. Specifically, a 3-phase electric motor and a heavy duty R-series inline gear motor:Motor Body

• Stator (Stationary part): Uses high-grade silicon steel sheets with low magnetic loss, wound with refined copper wire of high conductivity, helping the motor achieve an actual power of 2.2kW efficiently and run cool.
• Rotor (Rotating part): The shaft is machined from high-quality hardened steel, undergoing a rigorous dynamic balancing process to eliminate vibrations, ensuring the shaft always operates smoothly under a 3Hp load.

R-Series Gearbox (Transmission Part)

• Helical gear system: Gears are precision-machined and ground (tooth ground) using CNC machines, creating a tight mesh between the helical gears. This helps the system operate extremely quietly, limit noise, and withstand sudden load shock forces.
• Bearings & Oil seals: Equipped with high-quality axial load bearings, helping to center the rotating shaft stably. A specialized multi-layer oil seal system prevents lubricating oil leakage from the inside while protecting the gearbox from external dust intrusion.

Technical Specifications of Heavy Duty R-Series Inline Helical Gear Motor 2.2kW 3Hp

Designed with a sturdy structure, stable transmission capability, and high torque. The product is suitable for many industrial machinery systems requiring continuous and durable operation.

Applications of Heavy Duty R-Series Inline Helical Gear Motor 2.2kW 3Hp

• Conveyor & handling systems: Provides powerful and steady pulling force for conveyor systems, bucket elevators, or screw conveyors to move heavy materials and goods in factories or production workshops.
• Industrial mixers: Adjusts rotational speed and generates high torque, ideal for concrete mixers, animal feed mixers, or liquid material agitators, helping materials mix evenly while saving electricity.
• Lifting equipment: Ensures safe load capacity and powerful lifting force for freight elevators, cable winches, overhead cranes, and industrial forklifts.
• Crushers & presses: Provides stable and powerful drive force to operate scrap crushers, pellet presses, or hydraulic presses.
• Mechanical machining & manufacturing: Attached to industrial machines such as milling machines, cutting machines, and steel bar bending machines to precisely adjust cutting/bending speeds and ensure product smoothness.

Instructions for Installing the Heavy Duty R-Series Inline Gearbox with a 3-Phase Electric Motor

• Step 1: Position the electric motor, ensuring the front flange of the motor is clean and ready for assembly.
• Step 2: Bring the gearbox into position, aligning the motor shaft and the gearbox hole so they lie on an exact straight line.
• Step 3: Perform assembly by gently pushing the gearbox onto the motor shaft until it touches the flange.
• Step 4: Rotate the gearbox gently to ensure the positioning holes on the flanges of both devices are aligned.
• Step 5: Install bolts into the positioning holes and use tools to tighten all screws thoroughly to complete the assembly process.
