Rotary Motion/Planetary Gear Reducers/

  • Product Details
  • Inquiry

A speed reducer lowers input shaft rotation speed. It multiplies output torque. The reducer uses gear trains or friction drives. Common types include planetary, helical, worm, and cycloidal. Input connects to a high speed motor. Internal gears transfer power through meshing teeth. Output shaft turns slower but with greater force. The reduction ratio equals input speed divided by output speed.

Speed Reducer

The Speed Reducer first goes into a protective inner box. We then insert that box into a plywood outer case. This packing method secures the unit for any journey.

FAQs

  • Can a speed reducer run backwards?

       Yes, most reducers run in both directions. Worm reducers may lock when back driven. Check the manufacturer’s direction rating. Back driving can overheat some units. Use a backstop for one-way loads.

  • What is a single stage planetary reducer?

       A single stage Speed Reducer has one set of gears. It uses a sun gear and planet gears. A ring gear surrounds them. The input turns the sun gear. The planet carrier gives the output.

  • What reduction ratios does a single stage offer?

      Single stage ratios range from 3:1 to 10:1. Common ratios are 3, 4, 5, 7, and 10. You cannot get 100:1 from one stage. That would need multiple stages. Select the ratio for your speed need.

  • What bearings does a single stage Speed Reducer use?

Tapered roller bearings handle axial loads. Deep groove ball bearings handle radial loads. Needle bearings support the planet pins. Bearings determine the service life. Good bearings last 20000 hours.
