Determine the still left or right hand Scroll Vacuum Pumps guideline of the worm wheel relative to the worm. When the worm is usually right-handed (the worm is also rotated to the left and best and the judgment technique is the same as the direction of the helical gear), the right-hand rule can be used. The worm gear reducer is normally left-handed when left-handed. legislation. The four fingertips are bent in the direction of the direction of the worm (the directly arrow indicates the direction of circular movement 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 partnership between the worm and the turbine in the worm reducer depends upon The relative position between your two, the path 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 can be rotated clockwise and counterclockwise. There are four cases in total:
1. The worm rotates to the left, the worm is certainly on, and the worm is usually down. The right hands rotates the worm clockwise, and the worm steering wheel rotates counterclockwise;
2. The worm rotates to the left, the worm is usually under, and the worm is normally on. The right hands rotates the worm clockwise, and the worm steering wheel rotates clockwise;
3. The worm rotates to the right, the worm is normally on, and the worm is definitely down. The right hands rotates the worm clockwise, and the worm steering wheel rotates clockwise;
4. The worm rotates to the proper, the worm is normally on, and the worm can be down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
