Convert … Internal gear pumps have better suction capabilities than external gear designs and are more suited to high viscosity fluids, although they have a useful operating range from 1cP to over 1,000,000cP. A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. Looking at the chart above, we can see that the internal ratio is 0.279 for gear #1 and 1.467 for gear #14. Used in countless low-, medium- and high-pressure applications up to 420 bar peak pressure, hydraulic internal gear pumps from Voith ensure high volumetric and mechanical efficiency and low-pressure pulsation. If the input shaft is connected to the sun gear and output shaft to an arm on which the planet gear is mounted (referred to as the carrier), the gear ratio is calculated as: u = (R / S) + 1. External spur and helical gears as well internal gearings are possible to calculate. Introduction. Slip is determined . Requires an HTML 5-compliant browser.
