Internal Geneva Drive: Index Angle and Dwell Calculator | FIRGELLI
Calculate index angle, accumulated output travel and motion/dwell intervals for an ideal internal Geneva. Explore the radial-slot and drive-pin motion.
Geneva Drive (external) Mechanism Explained: How It Works, Diagram, Parts, Formula & Uses
Geneva Drive explained — how the external Geneva mechanism converts continuous rotation into precise indexed motion for film projectors, turrets, and packaging lines.
Maltese Cross Mechanism: Exact External-Geneva Timing
Explore an external Geneva mechanism. Calculate output step, driver indexing angle and dwell time from slot count and constant driver speed.
Intermittent Motion: Geneva Index and Dwell Calculator | FIRGELLI
Compare ideal Geneva step and index/dwell fractions, including an overlap warning for equally spaced pins. Physical multi-pin compatibility is not established.
Intermittent Transmission: Geneva Engagement Time Calculator | FIRGELLI
Calculate ideal one-pin external-Geneva step, index and dwell shares, and engagement time at constant driver speed. Settling and operating-speed limits are not calculated.
Intermittent Rotary Motion: Geneva and Carousel Pitch Calculator | FIRGELLI
Compare external-Geneva output step, driver engagement and dwell with carousel station pitch. The calculator identifies a direct pitch match, not a complete mechanism design.
Intermittent Gears: Angular Segment Calculator | FIRGELLI
Compare toothed and locking angle shares and check whether they total 360°. Output travel, tooth geometry and working lock dimensions are not calculated.
Indexing Motion: External Geneva Phase Calculator | FIRGELLI
Calculate ideal output step and index/dwell fractions for a standard external Geneva. An optional reference span rescales the reported phase angles.
Geneva Drive: External Indexing Geometry and Dwell Formula | FIRGELLI
Understand a standard external Geneva drive, calculate step angle and dwell time, and compare four-, six- and eight-slot timing with worked examples.
