ZAR5 calculates all gear data, tool dimensions, tooth thickness, flank clearance, backlash, span width, dimension over/between pins and balls, tolerances and permissible errors according to ISO 1328 or DIN 3961.
The Planetary Gear block models a gear train with sun, planet, and ring gears. Planetary gears are common in transmission systems, where they provide high gear ratios in compact geometries. A carrier connected to a drive shaft holds the planet gears.
15 mar 2022 · Planetary gears are at the heart of modern engineering and are used in basic plant machinery to electric vehicles. These are also known as epicyclic gears, consist of two gears so that the center of one gear rotates around the center of the other.
15 mar 2024 · The torque analysis of a planetary gear set involves determining the dynamics of the gear nodes, which can be achieved by examining the free-body diagram of the system. This diagram illustrates the forces acting on each component of the gear set, including the sun gear, planet gears, and ring gear, as well as the carrier.
For a planetary gear stage we need at least two shaft groups. With a right mouse click on ‘Shafts’ in the system add a ‘Group’ and a ‘Planetary group’. For the ‘Main group’ we add three shafts named ‘Sun shaft1’, ‘Ring shaft’ and ‘Carrier shaft1’. For the PlanetGroup1 we add two shafts named ‘Pin1’ and ‘Planet shaft1’.
The planet gears, which are mounted on a carrier, mesh with both the sun gear and the ring gear simultaneously, creating a compact and highly efficient gear arrangement, as shown in the diagram below.
