Types of Gear Reducers We Offer

At Industrial Exchange, we offer a comprehensive range of used gearboxes, which are categorized by their functionality.

Helical Gear Reducers

These mechanical devices feature helical gears and are used for high speeds. They amplify torque while reducing rotational speed between shafts. The gear teeth are angled to the shaft’s axis, facilitating quieter operation than other gear reducers.

Worm Gear Reducers

These right-angled speed reducers offer maximum speed reduction in a small package or constrained spaces. They are ideal for low to moderate horsepower applications that require high ratio speed reduction.

Planetary Gear Reducers

These reducers use multiple planet-like gears in the outer ring that orbit around a main central or sun gear. They offer superior torque vs. size ratio, precision, and durability compared to inline gears.

Bevel Gear Reducers

This gearbox type uses bevel gears to transmit power between two shafts positioned at a 90-degree angle. Bevel gear reducers may be either straight-cut or helical.

Inline and Right-Angle Gear Reducers

Inline gear reducers maintain the same orientation between the input and output shafts, whereas right-angle gear reducers change the direction by 90 degrees.

Why Buy Used Gear Reducers?

  • Cost-effectiveness: Used gear reducers are available at lower prices, and we ensure they are in good working condition, reducing repair and maintenance costs.
  • Immediate availability: They are almost always available immediately, preventing production downtime.
  • Environmental sustainability: Buying used gear reducers helps save resources and reduce environmental impact.
  • Reduced depreciation: Used gear reducers undergo lesser depreciation over time compared to new ones.

How to Choose the Right Gear Reducers

  • Understand your requirement: Analyze your application requirements and match them with the necessary gear ratio, torque, load type, and available space.
  • Input/output speed: Consider the gear ratio and balance between torque and speed reduction.
  • Shaft orientation: Decide between parallel (inline) or right-angle orientations based on your load and space constraints.
  • Operating environment: Consider factors like temperature, humidity, and exposure to corrosive materials when selecting materials like cast iron or aluminum.
  • Mounting style: Ensure compatibility with your mounting space and configuration.
  • Service factors: Choose the appropriate service factor based on shock loads and duty cycles.

Applications of Gear Reducers

  • Heavy engineering and manufacturing units
  • Mining
  • Packaging
  • Material handling equipment
  • Rotary furnaces
  • Robotics

Frequently Asked Questions (FAQs)

  • What is a gear reducer vs gearbox?
    A gearbox is an assembly of gears and components, while a gear reducer is a device designed to reduce speed and increase torque.
  • Can I use a gear reducer with my existing motor?
    Yes, but ensure compatibility with your motor's features.
  • Do you test used gear reducers?
    Yes, each gear reducer undergoes rigorous testing before being shipped.
