Bonfiglioli 317L Series Planetary Gearbox Reducer Replacement 317L1 317L2 317L3 317L4
The 317L Series Planetary Gearbox works by transmitting torque from an input shaft to an output shaft through the use of the planet gears. The input shaft is connected to the sun gear, which rotates at a constant speed. The planet gears are mounted on a carrier that can rotate around the sun gear. The carrier is connected to the output shaft, which receives the output torque.
317L Series Planetary Gearbox
A planetary gearbox is a type of gearbox that consists of a central sun gear, an outer ring gear (also known as a ring gear or annulus), and multiple planet gears that rotate around the sun gear and mesh with the ring gear.
The 317L Series Planetary Gearbox works by transmitting torque from an input shaft to an output shaft through the use of the planet gears. The input shaft is connected to the sun gear, which rotates at a constant speed. The planet gears are mounted on a carrier that can rotate around the sun gear. The carrier is connected to the output shaft, which receives the output torque.
As the sun gear rotates, it drives the planet gears, causing them to rotate around the sun gear while also rotating on their own axes. The planet gears also mesh with the ring gear, which is fixed in place, causing the ring gear to rotate in the opposite direction to the planet gears. This creates a gear reduction effect, which increases the output torque and decreases the output speed relative to the input speed.
The 317L Series Planetary Gearbox is a highly efficient gearbox, with low backlash and high torsional stiffness. It is also compact and lightweight, making it ideal for use in a wide range of industrial and automation applications.
