Determine the left or ideal hand guideline of the worm wheel in accordance with the 
worm. When the worm is certainly right-handed (the worm is also rotated left and ideal and the judgment method is equivalent to the direction of the helical gear), the right-hand rule is used. The worm equipment reducer is left-handed when left-handed. law. 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 side of the worm), and the contrary direction of the thumb is the direction of motion of the turbine relative to the worm. The relationship between your worm and the turbine in the worm reducer depends upon The relative position between your two, the direction of rotation of the worm and its direction of rotation.
The worm rotation direction (discussing the direction of the lead angle of the worm itself) is split into left-handed and right-handed, and both left-handed worm and the right-handed worm could be rotated Vacuum Pump clockwise and counterclockwise. There are four situations in total:
1. The worm rotates left, the worm is normally 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 definitely under, and the worm is certainly on. The right hand rotates the worm clockwise, and the worm steering wheel rotates clockwise;
3. The worm rotates to the proper, the worm is certainly on, and the worm is normally 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 certainly down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
