Planetary Gear Calculator vs SimTunnel Lite Usage & Stats

Planetary Gears Calculator calculate the gear teeth and gear speed of planetary gears system. Plus quickly simulate how the Planetary Gears works on the fly. This is a great tool, especially for DIYer who want to design their own Planetary Gears System quick and easy. Preview how these systems work before 3D print own planetary gear system. Formula for Planetary gear systems: Sun Teeth = ringTeeth - 2 * planetTeeth Planet Teeth = (ringTeeth - sunTeeth) / 2 Ring Teeth = sunTeeth + 2 * planetTeeth ST = sunTeeth PT = planetTeeth RT = ringTeeth SunSpeed = (ST+RT)/ST * PlanetCarrierSpeed - RT/ST * RingSpeed PlanetCarrierSpeed = RT/(ST+RT) * RingSpeed + ST/(ST+RT) * SunSpeed RingSpeed = (ST+RT)/RT * PlanetCarrierSpeed - ST/RT * SunSpeed Planetary gear systems, also known as epicyclic gear systems, are important components in modern engineering. Planetary gear systems are useful for speed variation and commonly found from automatic car transmissions and industrial food mixers to operating tables and solar arrays. There are four core components that make up the planetary gear systems, the ring gear, the sun gear and the planetary gears connected to the carrier.

SimTunnel Lite

SimTunnel Lite is designed to perform a quick tunnel analysis on your phone device. SimTunnel Lite is very simple and easy to use. SimTunnel Lite uses "rock-support interaction" or "convergence-confinement" method to estimate the deformation of circular tunnels in weak rock, and visualizing the tunnel interaction with various support systems. SimTunnel Lite has the following features: - SimTunnel Lite determines Factor of Safety (FOS) as the ratio of maximum support pressure to the support pressure required for equilibrium. - The Tunnel and Rock Parameters dialog allows you to define the tunnel and rock properties for model. - The Strength Properties which are required will depend on the strength criteria you have selected in Setting Page. - Both Mohr-Coulomb and Hoek-Brown strength criteria are available. - The parameter calculator dialogs are available to help you to calculate some of the parameters (i.e. GSI, mi, D, UCS, insitu stress and etc). - The support parameters dialog allows you to easily add support (i.r. Rockbolt) and define the support properties for the model. - Rockbolt support type can be added to the model. - The ground reaction curve (GRC) is always displayed in the output page. - The brief summary of analysis results and input data will be displayed in the Output Page. - The report button, allows you to save the current model’s input and output information into PDF file. The generated report file can be sent out via email.
