Looking at pictures of keyword “Wells” or “Jinming” gears as well as 18/1 and 16/1 ratio gears online:
-Both pinion gears have 10 teeth
-Both bevel gears have 30 bevelled teeth with 10 lower teeth for interaction with the spur gear
I think they’re more ratio specific than model specific but I can’t measure the dimensional differences since I don’t have “Wells” or 16/1 ratio gears on hand
It’s usually the spur gear that has more/less teeth, right?
If the gear ratios weren’t different on the pinion and bevel gear, maybe the height or placement of the pinion gear on the motor’s axle was different/out enough and it clashed with the bevel gear so badly on the first use that they didn’t give you a chance to adjust it? (would think proper metal gears would be tough enough for a small misalignment during initial adjustment/fine tuning)
I know this is an older-ish thread but, anyone else have confirmation or proper dimensions/config for the differences in gear ratios/models to potentially save someone in the future?
