R Series Helical Gear Hardened Reducer

Model 17—167

  • R series reducer are based on the building block design, so it's convenient for them to fit all types of motors or to connect with other power input. The same type or can fit motors with different power, so that it's possible for different types of machines to combine or connect.
  • High transmission efficiency. A single machine can reach a transmission efficiency as much as 96%
  • Precise division of transmission ratio with a wide range. The combination of machines can produce a larger transmission ratio at a low output rotate speed.
  • Various ways of installation. Horizontal installation at any position or flanged installation.

Rexon Drive suspension gearboxes, like helical gearboxes, consist of a number of diagonal gears, with the difference that by having several parallel axes, it has enabled the transmission of torque and a high conversion ratio. Also, due to the bearing of the output shaft on both sides, hanging gearboxes can withstand more radial loads than helical gearboxes.

  1. High Reduction Ratios:

    • Worm gear motors provide a high reduction ratio, enabling the transmission of force with a significant ratio, especially suitable for applications requiring high torque.
  2. High Efficiency:

    • Due to the unique helical worm design, these gearboxes generally exhibit high efficiency in power transmission.
  3. Low Noise and Vibration Levels:

    • The helical worm design contributes to lower noise and vibration levels compared to some other gearbox types.
  4. Resistance to Armature Load:

    • Worm gear motors typically offer high resistance to armature load, making them suitable for applications where force needs to be held without unwanted movement.
  5. Applications:

    • Worm gear motors find applications in scenarios requiring high reduction ratios and substantial torque. Common uses include elevators, conveyors, industrial machinery, and various industrial systems.
  6. Corrosion Resistance:

    • Incorporating corrosion-resistant materials in the worm and worm wheel structure enhances resistance to corrosion.
  7. Compact Structure:

    • The compact design of worm gear motors, featuring the worm and worm wheel, contributes to their robustness and ability to handle high loads.
  8. Low Maintenance and Long Lifespan:

    • The special design of the worm and worm wheel often results in lower maintenance requirements, contributing to a longer operational lifespan.
  9. Resistance to Corrosion:

    • Using corrosion-resistant materials in the construction of the worm gear helps enhance resistance to corrosive environments.
  10. Durable Construction:

    • The robust design of the worm gear motor, especially the worm and worm wheel, contributes to its durability and resistance to high pressures.
  11. Efficient Power Transmission:

    • Worm gear motors efficiently transmit power due to the helical worm design, making them suitable for various industrial applications.
  • Rexon Drive suspension gearbox is very strong and is used in steel industry. 
  • parallel shaft gearbox is made of steel and is very resistant for heavy work.
  • suspension gearbox motor has proper bearings.
  • high-quality suspension gearbox is sealed, which prevents leakage.
  • The worm gear motor typically offers high resistance to armature load, making it suitable for applications where force needs to be held without unwanted movement.
  • Using corrosion-resistant materials in the construction of the worm gear helps enhance resistance to corrosive environments.
