I'm looking for right angle gearbox, but everything is horrible expensive or in parts like two bevel gears from aliexpress. Where I can find or how to name transmission like this in the picture but in box case (if possible with mounting holes)?
I need right angle transmission 1:1, no matter what type of gear or something else. Looking for compact size, outer size of one arm, max 40mmx40mm. Maybe I don't know proper name to find it.
Also if I don't find good out of the box solution, how to proper design that type of transmission? I know I need bearings on shaft and screw, but how to avoid skipping on teeth?
