benredstar Posted May 26, 2017 Posted May 26, 2017 Hello Technic Wizards I am building a mechanism using worm gears https://www.bricklink.com/v2/catalog/catalogitem.page?id=1311#T=C. However, the ones I have in my collection have no friction against the cross axle I slide them onto; they just freely slide up and down. Is this the normal behavior? I need them to be fixed to the axle so they actually push things! Thanks in advance if anyone can throw any light. /ben Quote
allanp Posted May 26, 2017 Posted May 26, 2017 This is normal for the 2M worm gears. The new 1M worm gear however has friction with the shaft and the now rare 3M wormgear can't slide at all as an axle won't go all the way through. 2M through hole without friction. 3M blind holes either end. 1M through hole with friction.

Didumos69 Posted May 26, 2017 Posted May 26, 2017 If you actually want to push things then wouldn't it be better to use linear actuators? https://www.bricklink.com/v2/catalog/catalogitem.page?P=92693c01#T=C Quote

Gaofar Posted May 26, 2017 Posted May 26, 2017 Simple bricklink search under technic gear, the type in worm, and VIOLA!! Quote
Jurss Posted May 27, 2017 Posted May 27, 2017 This is new part. Comes in some 2017. sets. Cheapest 42060: Roadwork Crew Anyway, to push something, also friction of that won't be enough. You will still need some stoppers at each end. Also they are needed anyway to hold axle, on which You will mount that gear. Quote
