Planetary Gearbox Animation

It is easier to look the planetary as a black box and play with it.

Planetary gearbox animation. Locking different parts makes the gear deliver different gear ratios. The planet gears and the planet gears carrier. The animation below is exactly for that. Gear generator is a tool for creating involute spur gears and download them in svg format.

Choosing which piece plays which role determines the gear ratio for the gearset. Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer or planet gears or pinions revolving about a central sun gear or sun wheel. Planetary gear with fixed ring gear. Have you ever wondered how you can get so much power and capabilities in such a little hub.

A planetary gearbox is used to transfer the largest torque in the most compact form known as torque density. The sun gear is twice the diameter of the planet gear and the ring gear is twice the diameter of the sun gear. To save the gears animations right click on the gif or for touchscreens press down on the graphic for several seconds. Typically the planet gears are mounted on a movable arm or carrier which itself may rotate relative to the sun gear epicyclic gearing systems also incorporate the use of an outer ring gear or annulus which meshes.

For a three speed hub a one stage planetary gear system is. In addition it let you compose full gear layouts with connetcted gears to design multiple gears system with control of the input output ratio and rotation speed. On an involute profile gear tooth the contact point starts closer to one gear and. They are connected by an axle which is also the output axle of the gearbox to the wheels.

Every bit of love helps. The animations shown below are designed to help you gain some insight into the behavior of planetary gearsets. Each of these three components can be the input the output or can be held stationary. Gears can be animated with various speed to demonstrate working mechanism.

Animation of involute gear. Please give me a link back on your homepage or blog. In the present case one also obtains a reduced rotational speed because the transmission ratio will be greater than 2 in any case since the number of teeth of the ring gear is always greater than that of the sun gear the teeth ratio is thus greater than 1 frac z r z s 1. A planetary gear keeps rotating if one part is blocked.
