Ring gear B is coupled to planet gears S1, which are coupled to Sun M1. [5] Ring R1 is coupled to planets S2, which are coupled to Sun C. Planet gears from the S1 set are pairwise coupled to S2 gears. The output can be coupled to either one of the ring gears, with R1 being used in all forward speeds and B in the reverse speed.
Gain and Watts Calculator; Mike Sherman's gear calculator Archived 2011-03-10 at the Wayback Machine Online calculator for derailleur gears, with useful graphic displays; HPV Drivetrain Analyzer A drivetrain analyzer and gear calculator for HPV's (Human Powered Vehicles) that will handle compound drives and geared cranks and hubs.
This planetary gear train consists of a sun gear (yellow), planet gears (blue) and carrier (green) inside a ring gear (red) An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun"). A ...
The reduction gear is a standard unit known from the art. [5] All planet gears of the first 2 planetary systems are on the same carrier (4 gears on each axle, with each set of 2 locked to the same shaft, i.e. 2 shafts rotating on a common axle). The common planet carrier is the means to transfer power between planetary system one and two.
The stepped reckoner was based on a gear mechanism that Leibniz invented and that is now called the Leibniz wheel. It is unclear how many different variants of the calculator were made. Some sources, such as the drawing to the right, show a 12-digit version. [5] This section describes the surviving 16-digit prototype in Hanover. Leibniz wheel
Tim Allen’s new ABC sitcom “Shifting Gears” is revving its ratings engine. According to ABC, the series now stands as the most-watched ABC series premiere on streaming to date, via first ...
The involute gear profile, sometimes credited to Leonhard Euler, [1] was a fundamental advance in machine design, since unlike with other gear systems, the tooth profile of an involute gear depends only on the number of teeth on the gear, pressure angle, and pitch. That is, a gear's profile does not depend on the gear it mates with.
The 9HP is only 0.24 inches (6 mm) longer than, and weighs 16.5 lbs (7.5 kg) less than, the outgoing six-speed transmission. The compact packaging is achieved by using a number of innovative design features: a new compact hydraulic vane-type pump, two patented dog clutches, [3] which replace bulkier conventional clutch packs, and a nested gear set.
