Building a Bevel gear Gear Box
Building a Bevel gear Gear Box
Lately I found out there are a number of very good bevel gear gear boxes available.
All using geared motors.
It is amazing how simplistic these gear boxes actually are against the modification of a standard gear box I did before.
Looking on the internet I found bevel gears with module 1 15 teeth and a 6mm bore.
Making them small enough to be viable for my project.
Also I found Merkle-Kroff geared motors that just stated 6-12 volt 30 rpm.
When I received them I soon realized I had a problem.
The motors rpm's where way to slow, the drive shaft was 1/4 inch and 10mm to short.
All the screw sizes had some strange American threads.
I had to re tap the mounting screw holes to be able to use screws I had.
But the overall quality was very good.
Here is how I went about it.

Old and new main gear shaft. New shaft is 10mm longer.

Side plate. It also will be used to fix the gear box to the side wall of the tank.
