Determine the remaining or ideal hand rule of the worm wheel in accordance with the worm. When the worm is usually right-handed (the worm can be rotated left and ideal and the judgment technique is the same as the Rotary Air Compressors direction of the helical gear), the right-hand rule is used. The worm equipment reducer is usually left-handed when left-handed. regulation. The four fingertips are bent in the direction of the path of the worm (the straight arrow indicates the direction of circular motion on the visible part of the worm), and the contrary direction of the thumb is the direction of motion of the turbine in accordance with the worm. The relationship between the worm and the turbine in the worm reducer depends upon The relative placement between your two, the direction of rotation of the worm and its 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 can be rotated clockwise and counterclockwise. There are four cases in total:
1. The worm rotates to the left, the worm can be on, and the worm is 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 on. The right hands rotates the worm clockwise, and the worm 
wheel rotates clockwise;
3. The worm rotates to the proper, the worm is certainly on, and the worm is definitely down. The right hand rotates the worm clockwise, and the worm steering wheel rotates clockwise;
4. The worm rotates to the right, the worm is on, and the worm is definitely down. The right hands rotates the worm clockwise, and the worm wheel rotates counterclockwise;
