Determine the still left or best hand rule of the worm wheel relative to the worm. When the worm is definitely right-handed (the worm can be rotated to the left and right and the judgment method is the same as the path of the helical equipment), the 
right-hand rule is used. The worm gear reducer is usually left-handed when left-handed. rules. The four fingertips are bent in the direction of the direction of the worm (the directly arrow indicates the direction of circular motion on the visible part of the worm), and the opposite path of the thumb is the direction of movement of the turbine relative to the worm. The relationship between your worm and the turbine in the worm reducer depends upon The relative placement between the 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 could be rotated China Vacuum Pumps clockwise and counterclockwise. There are four instances in total:
1. The worm rotates left, the worm can be on, and the worm is usually down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
2. The worm rotates to the left, the worm is normally under, and the worm is on. The right hand rotates the worm clockwise, and the worm wheel rotates clockwise;
3. The worm rotates to the proper, the worm is usually on, and the worm can be down. The right hands rotates the worm clockwise, and the worm wheel rotates clockwise;
4. The worm rotates to the right, the worm can be on, and the worm is down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
