Expression of the model:


Single-Stage Helical Transmission Structure
The REC series adopts a single-stage helical transmission design to provide efficient and reliable torque output. The gearmotor is compatible with three types of input structures: direct motor connection, shaft input, and flange input. It can be installed in both horizontal and vertical positions, providing flexibility for layout requirements. The single-stage configuration delivers moderate gear ratios while ensuring smooth operation. This structure allows integration into various systems needing gear reducer performance and precision. The simple transmission stage reduces complexity and wear, making it well-suited for environments where consistent torque and speed are essential. The build quality aligns with typical expectations from leading industrial gearbox manufacturers.

Power and Torque Specification Coverage
The product covers a broad power range from 0.18 kW to 45 kW, with torque output reaching up to 900 Nm. Output speeds range between 230 and 918 rpm depending on the model. The product series includes multiple sizes, from REC31 to REC101, each offering variations in shaft diameter, flange diameter, center height, and total unit weight. Weight data is based on reducer alone and increases by approximately 10 percent when including oil, motor, flange, and other accessories. The gear ratio ranges from about 1.5 to 6.6. These detailed mechanical specifications support wide applicability across gear box motor systems and configurations requiring a dependable gear reduction box.

Model Range and Dimensional Options
Seven models make up the REC series: REC31, REC41, REC61, REC71, REC81, REC91, and REC101. Each model is engineered to meet specific torque and power outputs, with center heights increasing from 40 mm to 110 mm and torque levels from approximately 50 Nm to 850 Nm. The gearmotors also offer several shaft and flange diameter options for output adaptation. This allows users to match performance demands precisely, especially when implementing worm gear reducer systems or integrating into a broader electric motor gearbox application. The standardization of dimensions ensures ease of installation and replacement across various system types.


 
Product Advantages

Optimized for Torque and Speed Output
The REC series supports a wide torque range up to 900 Nm and variable output speeds suited to applications requiring consistent power transmission. Whether deployed in light-duty or heavy-duty operations, this product enables efficient motion control while minimizing energy loss. Its design suits those in need of high‑precision gearbox reducer performance. By maintaining a consistent torque curve and smooth output, it serves as a strong choice among worm gearbox and gear motor reducer competitors.

Adaptable to Multiple Installation Needs
This gearmotor supports vertical and horizontal installations, allowing engineers to design systems that fit space constraints or orientation preferences. Input flexibility further enhances system compatibility, supporting direct motor input, flange mounting, or shaft configurations. This degree of adaptability is critical in equipment that must comply with varying industrial layouts. These features make it highly usable in gearmotor systems and reducer gearbox machinery requiring customized setups.

Simplified Transmission for High Durability
The single-stage helical transmission minimizes internal friction and noise. With fewer meshing surfaces than multi-stage options, the mechanism is simpler and thus less prone to mechanical wear. This structure improves long-term stability and service life. It also allows easier maintenance and better mechanical efficiency when compared to more complex worm gear box assemblies. These characteristics make it a valuable option for engineers looking for long-lasting and efficient gear reduction box systems.


 
Use Scenarios

Conveyor Systems and Material Transport
The gearmotor performs reliably in conveyor lines where consistent output torque and moderate speed are essential. It can be implemented in horizontal or vertical layouts, depending on the equipment’s structure. Suitable for long belt systems or automated sorting lines, its mechanical configuration provides stability under continuous operation. In such cases, it acts as the core speed reducer gearbox and aligns with requirements for gear box motor installations in industrial motion control systems.

Heavy Equipment and Power Applications
The gearmotor’s maximum torque output of 900 Nm enables its application in mining machines, crushers, hydropower station drives, and chemical process equipment. Its ability to support high loads in rugged environments enhances operational reliability. With options for flange or shaft input, it can be easily integrated into large‑scale mechanical systems. These advantages align with worm drive gearbox and power steering gear box requirements where strong load bearing and torque delivery are crucial.

Machinery Manufacturing and OEM Systems
With various sizes and performance ranges, the gearmotor is ideal for use in printing presses, packaging machines, and textile or food production equipment. Equipment manufacturers benefit from its flexible design, allowing easy integration into custom machinery without extensive redesign. Its compact footprint and efficient performance also fit electric motor gearbox setups in OEM environments. The availability of multiple configurations ensures compatibility with a range of type of gear box layouts and requirements.
