dickyho is making me some. My version is D bore(10mm x 9mm). The circle bore won’t be safe for me. Thanks for help, though.
@dickyho Thanks man! I got it. it came out good. I will test it out and see how long it will last.
I’m going to post my results here. The right motor is going to have the aluminum motor pulley and the left motor is going to have the steel version. I will measure the parts and see if the shape changes overtime. Tomorrow, I’m going to install it. I’m excited.
glad to know that items well received, expecting of the test!
Update
After riding my board since June 23, 2023. The steel motor pulley is require for heavy/crazy riders. I had the belt loose and tight. The material on the aluminum is to soft for my style/weight. At least @dickyho solved my issue quick. This is my result.
Left motor is steel pulley. Right motor is aluminum pulley. Both are new. Aluminum failed the test.
My opinions…
Anyone over 250 lbs… You need steel motor pulleys. if you are under 200 lbs. Use aluminum motor pulleys.
I am closer to 200lbs (215 lbs / 97kg) and aluminum motor pulleys don’t last long at all. I even wear out steel ones, but it takes years. For wheel pulleys, aluminum is the material that lasts years, and plastic / nylon ones wear out quickly.
72T nylon holds up well, wear is inversely proportional to tooth count
Agree, the 32T to 44T range is where I’d use aluminum
Steel under 20T and aluminum under 50T then nylon is fair game?
My experience lines up with that, as a heavy dude. Not sure about others.
I noticed that if your motor pulley has less teeth. The material gets deform quick. The more teeth you have on your motor pulley. The teeth is still good just like how I got it. Here is my theory about this… The bigger the pulley is… The pressure and pull even out on the surface area. I don’t know… I’m probably talking s***.lmao
No, you are right. Bigger pulleys do wear less.
I am very hard on 15T HTD5M motor pulleys
It’s not just the size of the pulley - it’s also the amount of engagement you have on it. Adding an idler can help, as you’re distributing the load across more area around the pulley.
thank you for explaining it.
I’ve often wondered if a key and keyway pulley would work on a D-shaft motor it’s making it a sort of D shape anyhow. and much easier to come by.
You could make a Đ shaped key
Instructions unclear, dick stuck in motor
I ended up cutting a keyway into my D shafted motors for more pulley compatibility.
On the flat side? ie it needed more room? or on the other side?
also… u can cut own keyway, that’s
