2-Stage UDL 0.8kW – R47 Gear Motor

The 2-Stage UDL 0.8kW – R47 Gear Motor is a gear motor assembled from an electric motor and a gearbox to create a powerful, stable drive system suitable for numerous industrial machinery systems. The R47 gearbox utilizes a helical gear mechanism for efficient power transmission, ensuring quiet operation, high pulling force, and minimized energy loss. This is the optimal choice for conveyors, mixers, presses, feeding systems, and other industrial equipment requiring stable power transmission and energy efficiency.

Overview of the 2-Stage UDL 0.8kW – R47 Gear Motor

Motor Overview

• Speed Variator (UDL – 0.8kW): The primary stage provides stepless speed adjustment via a mechanical handwheel based on the friction cone disk principle, enabling smooth speed variation without stopping the machine.
• Gearbox (R47): The secondary coaxial stage uses helical gears achieving 95-98% efficiency. The design optimizes load-bearing capacity and durability far superior to worm gearboxes.

Operating Characteristics

• Flexible Adjustment: Fine-tune output rotation speed during operation, meeting immediate production speed change requirements.
• Efficiency & Smoothness: Helical gear pairs ensure smooth operation, reduce heat generation, and preserve transmission power.
• Coaxial Structure: Input and output shafts are aligned inline, optimizing installation space for conveyor or stirrer applications.

Detailed Structure of the 2-Stage UDL 0.8kW – R47 Gear Motor

The 2-Stage UDL 0.8kW – R47 Gear Motor is assembled from a 3-phase 0.8kW 1Hp electric motor and a 2-stage UDL 0.8kW – R47 gearbox (2-stage UDL 0.8kW – R47 speed reducer). Its detailed structure is as follows:

Electric Motor Structure:

• Motor Housing: Made of rugged cast iron or aluminum alloy, offering good vibration resistance.
• Stator: The core and stator winding are constructed from laminated silicon steel sheets to minimize magnetic field losses.
• Rotor: A squirrel-cage rotor cast solidly with aluminum or copper conductor bars, providing high rigidity and balance.
• Motor Shaft: Manufactured from hardened alloy steel, resistant to warping and excellent at withstanding torsion.

Gearbox Structure:

• Stage 1 is the mechanical speed variator (UDL): Specifically, the 0.8kW 1Hp motor speed variator changes the input speed via a friction mechanism or gears before transmitting power to the next stage.
• Stage 2 is the R47 gearbox series: Specifically, the Heavy Duty R-Series Inline Helical Gear Motor (such as the Heavy Duty R-Series Inline Helical Gearbox 2.2kW 3Hp or Heavy Duty R-Series Inline Helical Gearbox 4.0kW 5.5Hp) thanks to its special design featuring a motor and gearbox with a sturdy, solid housing and long service life.
• Housing, Shafts, and Lubrication System: Cast iron housing, shafts rotating on ball bearings; gear oil is used for lubrication, friction reduction, and heat dissipation.

Technical Specifications of the 2-Stage UDL 0.8kW – R47 Gear Motor

The 2-Stage UDL 0.8kW – R47 Gear Motor is a mechanical drive integrated with stepless speed adjustment capabilities, suitable for systems requiring frequent speed changes during operation. The combination of the UDL mechanical speed variator and the R47 inline helical gearbox helps the equipment maintain stable output speed while enhancing transmission efficiency.

Technical Specifications of the 3-Phase 0.8kW 1Hp Electric Motor

The 3-phase 0.8kW 1Hp electric motor is designed according to industrial standards, offering stable performance and high reliability. The flange mounting style makes assembly with the UDL speed variator convenient, saving installation and maintenance time.

Technical Specifications of the UDL 0.8kW 1Hp Mechanical Speed Variator

The UDL 0.8kW mechanical speed variator uses a mechanical drive mechanism to continuously change speed within the allowable range. Operators can easily adjust the speed via a handwheel or control knob without interrupting system operations.

Technical Specifications of the R47 Inline Helical Gearbox

The R47 gearbox is designed with a concentric helical gear structure, helping to transmit power efficiently and minimize energy loss. Thanks to its 30mm output shaft diameter, the device can effectively meet medium load transmission requirements.

Applications of the 2-Stage UDL 0.8kW – R47 Gear Motor

The 2-Stage UDL 0.8kW – R47 Gear Motor provides powerful and stable transmission performance, making it flexibly applied across various production lines and industrial equipment.

• The R47 motor drives conveyors requiring slow speeds and high pulling force, keeping goods moving steadily and continuously.
• Thanks to its high torque, the motor is used for small presses, compression equipment, or force-generating mechanisms requiring stability during continuous operation.
• The motor assists in feeding or pulling materials into processing machines, making the production process more consistent and precise.
• The R47 gear motor helps control packaging conveyor speeds, ensuring smooth product transfer, minimizing errors, and increasing productivity.

Guide on Installing an Electric Motor with a Mechanical Speed Variator and R-Series Gearbox

• Step 1: First, place the mechanical speed variator into the exact input position of the R-series gearbox. Align it so that the output shaft of the speed variator fits completely and snugly into the shaft hole of the R-series gearbox, ensuring the flanges on both sides press tightly against each other.
• Step 2: Next, bring the electric motor close to the other end of the mechanical speed variator. Align the motor shaft and slowly insert this shaft deep into the shaft hole of the speed variator until the motor flange touches the speed variator body closely with no gap left.
• Step 3: Take the screws and thread them through the holes on the connecting flanges between the three components. Use a wrench or hex key to tighten all these screws securely to firmly fix the entire machinery system into a rigid block.

Note: Thoroughly clean all metal debris and excess grease on the shaft ends before assembly. When tightening screws, remember to tighten them evenly across all corners; do not fully tighten one screw first to avoid misaligning or warping the machine, which would cause loud noise or premature wear during operation.
