If we know the direction of rotation of the worm and worm wheel, if we want to judge the direction of rotation of the worm, we need to extend the right or left hand, half-make a fist, and make the thumb point to the opposite direction of the linear velocity direction of the meshing point of the worm wheel. The direction of the other four fingers is the same as the worm rotation direction, the worm should be right-handed, if it is the same as the left hand, the worm should be left-handed.
The rotation and direction of rotation of the worm are often known. The method to determine the direction of rotation of the worm is: when the worm is right-handed, stretch out your right hand, half-make a fist, and point to the direction of rotation of the worm with four fingers other than the thumb At this time, the direction opposite to the thumb pointing is the linear velocity direction of the worm wheel at the meshing point, and then the direction of rotation of the worm wheel can be known. When it is a left-handed worm, extend your left hand.
When the rotation direction of the worm and the rotation direction of the worm wheel are known, it is necessary to judge the rotation direction of the worm: when it is a right-handed worm, extend your right hand and half-make a fist so that your thumb points to the opposite of the linear velocity of the worm wheel at the meshing position Direction. At this time, the direction pointed by the other four fingers is the direction of rotation of the worm. In the case of a left-handed worm, extend your left hand and the judgment method is the same as above.
Worm gears have outstanding self-locking properties and are very useful in mechanical applications, such as winches, conveying equipment and so on. But also due to the friction transmission method of the worm and worm, the transmission efficiency of the worm and worm is much lower than that of the gear transmission.
In the transmission method of the reducer, the worm gear transmission has the characteristics that other gear transmissions do not have, that is, the worm can easily roll the worm wheel, but the worm wheel cannot roll the worm. This is because the structure and transmission of the worm gear is completed by friction. The above is the judgment method analyzed by worm and turbine manufacturers for everyone, and I hope it can be helpful to everyone!
