Re: [gingery_machines] Re: Gears

 

Yes I do ... SDP-SI for centre distance calculator, and info.
Also, Gates, HPC Gears, Dinamica, and all big pulleys dealers. Google
industrial power transmission +HTD

Hints:
Use 5 mm size pulleys for CNC and low power (under 20 Hp).
Use 15 mm wide pulleys for low backlash.
Minimum pulleys size is 14 teeth to get a good grip (12 is too small).
Max transmission is about 1:3 (or very big secondary pulley).
Use 2 setscrews.
One pulley needs flanges.

HTD can be self made, and proven over 15 years (google making HTD ...).
T5, PowerGrip, GT2 etc are not better for cnc or our type use, and cost
a lot more.
Do not use XL, L etc. for cnc, they are not positioning belts.
3 mm HTD is too small.

I use the same belts on 50 W steppers with 1 micron resolution,
and 2.2kW output industrial tablesaw (3500 rpm).

I bought my pieces in 100-300 pc lots, and got 60% off.
