3d models of sprocket couplings and conical helical toothing wheel

[Kaji]

Hi I should make a purely illustrative 3d model of a coupling between pinion and helical conical toothing wheel.
I wanted to ask if online are found simple 3d models with various reduction reports so that you can easily import and scale them.
thanks for the attention and availability.
