The bevel gear 3 and the worm gear are subjected to the axial force. What is the helix?
The axial force of bevel gear are made of small end points to the end, so the axial force of bevel gear 3,
At the same time, the problem shows that the force is offset against each other, so the axial force of the worm gear 2 is opposite to the axial force of the bevel gear 3.
The bevel gear 3 is smaller and which end points to the larger end, so to the left.
