Determine the left or right hand rule of the worm wheel in accordance with the worm. When the worm is right-handed (the worm is also rotated to the left and ideal and the judgment technique is equivalent to the Oil less Air Compressor direction of the helical gear), the right-hand rule can be used. The worm gear reducer is definitely left-handed when left-handed. regulation. The four fingers are bent in direction of the direction of the worm (the straight arrow indicates the direction of circular motion on the visible aspect of the worm), and the contrary path of the thumb may be the direction of motion of the turbine in accordance with the worm. The relationship between the worm and the turbine in the worm reducer depends on The relative position between your two, the path of rotation of the worm and its own direction of rotation.

The worm rotation direction (referring to the direction of the lead angle of the worm itself) is divided into left-handed and right-handed, and both the left-handed worm and the right-handed worm can be rotated clockwise and counterclockwise. There are four cases in total:

1. The worm rotates to the left, the worm is definitely on, and the worm is usually down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;

2. The worm rotates left, the worm is certainly under, and the worm is usually on. The right hand rotates the worm clockwise, and the worm steering wheel rotates clockwise;

3. The worm rotates to the right, the worm can be on, and the worm is usually down. The right hands rotates the worm clockwise, and the worm steering wheel rotates clockwise;

4. The worm rotates to the right, the worm is normally on, and the worm is usually down. The right hand rotates the worm clockwise, and the worm wheel rotates counterclockwise;
