Double Shaft Inline Planetary Reducer Low Backlash Planetary Gearing For Robotics

Planetary gearbox also known as a planetary gear system or epicyclic gear train, is a type of gear mechanism consisting of one or more outer gears (planet gears) revolving around a central (sun) gear. Typically, these systems also include a ring gear (annulus) that meshes with the planet gears. The planet gears are mounted on a movable carrier which also connects to the output shaft of the gearbox.

Key Features of Planetary Reducer

• High Torque Density  Planetary reducers can transmit large amounts of torque relative to their size, making them highly efficient.
• Compact Size  Due to their design, planetary reducers can achieve high power transmission in a relatively small package.
• High Efficiency  They typically have high efficiency and reliability, especially in applications requiring high reduction ratios.
• Load Distribution  The load is distributed among multiple planet gears, which allows for higher torque transfer and reduces wear on individual gears.
• Versatility  Planetary reducers can be used in various configurations, such as reducing speed or increasing torque in a wide range of mechanical applications.

Working Principle of Planetary Reducer

The planetary reducer system works by distributing the input power among the sun gear, planet gears, and ring gear. Here’s how it typically functions:

• The sun gear receives the input power and transmits it to the planet gears.
• The planet gears rotate around their own axes and also revolve around the sun gear.
• The planet gears are held in place by the carrier, which rotates and provides the output.
• The ring gear remains stationary or rotates, depending on the design and application, and meshes with the planet gears to maintain alignment and proper gear ratios.
