Determine the still left or best hand rule of the worm wheel in accordance with the worm. When the worm is normally right-handed (the worm is also rotated left and ideal and the judgment method is the same as the direction of the helical gear), the right-hand rule is used. The worm gear reducer is normally left-handed when left-handed. laws. The four fingertips are bent in direction of the path of the worm (the directly arrow indicates the direction of circular motion on the visible side of the worm), and the opposite path of the thumb 
may be 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 position between the two, the direction of rotation of the worm and its own direction of rotation.
The worm rotation direction (discussing 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 usually down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
2. The worm rotates left, the worm is normally under, and the worm is Dry Screw Vacuum Pumps definitely on. The right hands rotates the worm clockwise, and the worm wheel rotates clockwise;
3. The worm rotates to the right, the worm is definitely on, and the worm is definitely down. The right hands rotates the worm clockwise, and the worm wheel rotates clockwise;
4. The worm rotates to the proper, the worm can be on, and the worm is definitely down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
