Hi,
i'm looking at buying worm and worm gears from either smallparts or pic design for a mount, but needed help with specifications.
else if someone bought one, could you'll share specifications or sources.
i was looking at the pic catalogue of anti backlash worm wheels,
http://www.pic-design.com/Images/pdfcat/section_12.pdf
they've got the following parameters listed
pitch
face width
pressure angle
no of teeth
O.D
P.D
Bore D
what are the common pitch and pressure angles used in most scopes, how do you specify the number of teeth that have to be meshed?
do the springs in the antibacklash gears reduce backlash noticeably? anyone tried these?
i'm looking at a reduction ratio of around 300:1.
