Determine the left or best hand guideline of the worm wheel relative to the worm. When the worm is usually right-handed (the worm can be rotated left and best and the judgment method is equivalent to the direction of the helical gear), the right-hand rule can be used. The 
worm equipment reducer is normally left-handed when left-handed. rules. The four fingertips are bent in the direction of the path of the worm (the directly arrow indicates the path of circular motion on the visible side of the worm), and the contrary 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 Taper Pulleys 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 the left-handed worm and the right-handed worm could be rotated clockwise and counterclockwise. There are four instances in total:
1. The worm rotates to the left, the worm can be on, and the worm is definitely down. The right hand rotates the worm clockwise, and the worm wheel rotates counterclockwise;
2. The worm rotates to the left, the worm is usually under, and the worm is usually on. The right hands rotates the worm clockwise, and the worm steering wheel rotates clockwise;
3. The worm rotates to the right, the worm can be 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 is usually on, and the worm is down. The right hands rotates the worm clockwise, and the worm steering wheel rotates counterclockwise;
