Are the Helix Directions of the Worm and Worm Wheel the Same?

[LaMaci]

The helix directions of the worm and worm wheel are the same. Here is some related knowledge about the worm and worm wheel: Contact Stress: When the meshing teeth of the two gears come into contact, the action and reaction forces between the tooth surfaces generate contact stress on the working surfaces. Since the position of the meshing point changes and the gears undergo periodic motion, the contact stress varies in a pulsating cycle. Effects of Contact Stress: Under prolonged exposure to this alternating contact stress, small cracks may appear at the tool marks on the tooth surfaces. Over time, these cracks gradually expand horizontally across the surface layer. Once the cracks form a ring, they cause small areas of the gear teeth surface to peel off, resulting in fatigue pits.
