Hi to everyone,
as mentioned in the title, I was wondering how suitable would be worm gears in e-skate industry (more particulary mountainboards).
The "gear box " would take less space and be lighter than actual direct drives on the market. It might also be more quiet and durable.
It actually seems that they are less efficient than spur or helical gear, and bigger the ratio worth the efficiency. But with the ratios we use in e-skate (between 3 and 10) the lack of efficiency looks less important than with higher ratios.
What do you think? Could it be interesting or did I miss some important points?
The “worm” of the worm gear refers to a screw shape cut into a shaft that the mating gear, or worm wheel, is attached to. Due to sliding contact of the gear surfaces a hard material is generally used for the worm, so as to reduce friction. Though the sliding contact means that worm gears aren’t incredibly efficient, their rotation is very smooth and quiet. As such, they are often used for industrial applications, heavy equipment, and sometimes consumer goods.
Worm gears provide very high reduction ratios and are often self-locking, as they cannot function in the reverse direction. This inherent feature makes them a safe option to use in certain types of machinery. A common example of a self-locking worm gear is the machine tuning head found on many string instruments, including the guitar.
I’m pretty familiar with gears. Made many locker differentials, timing gears, center pivot irrigation wells, flood wells, holding pond gates. All gears. That’s not including all the farm equipment I’ve had to deal with. I made a mid drive bike motor with some gears off an old old reel style lawn mower. It was slow as fuck but would climb a wall. Lol.
Oh I know. Believe it or not only in the last 10 months have I taken pictures of my work. I take a couple of my bowls and doors I make. But skate/moto/anything like that I never kept a log of it. Most of the early stage stuff was drunken fun throw it together and see what happens then demolish it to keep anyone from seeing it. Lol
