Determination of rotation and rotation direction of worm and worm gear

(1) Knowing the direction of rotation and the direction of rotation of the worm, determine the direction of rotation of the worm wheel: when the worm is right-handed, extend the right hand, half clench the fist, with the exception of the thumb, the other four fingers pointed to the direction of rotation of the worm, at this time, and thumb pointed to the opposite direction is the direction of the linear speed of the worm at the meshing point, so that the worm can be known. The rotation direction of the wheel. When it is a left worm, extend the left hand and judge the same method.



(2) Knowing the rotation direction of the worm and the rotation direction of the worm wheel, determine the rotation direction of the worm: when it is a right-handed worm, extend the right hand, half clench the fist, so that the thumb points to the opposite direction of the linear speed of the worm wheel at the meshing point, at this time, the other four fingers point to the direction of rotation of the worm. When it is a left worm, extend the left hand and judge the same method.



(3) Knowing the rotation direction of worm and worm wheel, judging the rotation direction of worm: extending the right hand or left hand, half clenching the fist, so that the thumb points to the opposite direction of the linear velocity of the meshing point of worm wheel. At this time, if the other four fingers of the right hand point in the same direction as the rotation direction of worm, the worm should be right-handed, if the same as the left hand, The worm should be left.
