Determine the remaining or right hand guideline of the worm wheel relative to the worm. When the worm is Bearing definitely right-handed (the worm can be rotated to the left and ideal and the judgment technique is equivalent to the path of the helical gear), the right-hand rule can be used. The worm gear reducer is normally left-handed when left-handed. laws. The four fingers are bent in the direction of the path of the worm (the straight arrow indicates the path of circular motion on the visible part of the worm), and the opposite direction of the thumb is the direction of motion of the turbine relative to the worm. The relationship between the worm and the turbine in the worm reducer depends on The relative placement 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 left-handed worm and the right-handed worm could be rotated clockwise and counterclockwise. There are four cases in total:
1. The worm rotates left, the worm can be on, and the worm is normally down. The right hands rotates the worm clockwise, and the worm steering wheel rotates counterclockwise;
2. The worm rotates left, the worm is usually under, and the worm can be on. The right hand rotates the worm clockwise, and the worm wheel rotates clockwise;
3. The worm rotates to the proper, the worm is 
certainly 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 on, and the worm is certainly down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
