Thread: Belts and pulleys types???

Well theres XL and T5 which are trapezoid type timing belts and pulleys and I guess the standard belts, XL is imperial ~ 4.xxmm and T5 is a 5mm pitch.

AT5 not too sure what makes this any better than T5 but it has a 50 degree angle on the tooth instead of 40 degrees which the T5 and XL have, its also a larger tooth.

HTD5M has a more rounded tooth profile which is spose to reduce wear.


All these types should be easily avaliable online or from your local engineering mob, or you can buy some T5 from myself but I have a limited range.

i think the "T" series belt have the same profile for teeth and gap , so the belts can be ran face to face , as a belt/rack system ( tractor belt system ), hard to ex plane so heres a utube of what i mean [ame=http://www.youtube.com/watch?v=OdJoVh6DRPA]ServoBelt: amazing belt drive - YouTube[/ame]

Had a look on your web site and it look to me that you have what I will need and at a good price.

Thanks guys for the info

grunt would come from the size of the motor and gearing v's speed , up to a point when they just strip teeth of the kevlar belt ( same as a belt drive , with less belt stretch ), then go for a larger drive pulley and even lower gear , plenty of grunt if your near the snapping strain of a 50mm wide belt , if you tractor ("ARMY tank" track) the motor end , when you snap the belt your up for a ??/ 300mm long round belt only , yes the stuck down belt will ware as well , but if the contact surface on the stuck down belt is 10x the contact of the drive pulley , the drive belt will fail every time
