Information

To judge who is the worm wheel and worm, as long as it can be used as the active part, the worm wheel is the follower, because the worm gear transmission pair has self-locking characteristics. The part that opens and closes the adjusting wrench by turning the thumb in the movable wrench is a worm, because the one that opens the movable wrench can not be used as the active part.

1, difference

(1) The worm gear is equal to the gear; the worm is equal to the rack.

(2) The worm is the driving part; the worm wheel is the driving part.

(3) Many worm gears have an interesting feature that other gear sets do not have: the worm can easily rotate the gear, but the gear can not rotate the worm. This is because the protrusion angle on the screw is very shallow. When the gear tries to rotate the screw, the friction between the gear and the screw will keep the screw in place.

2. Judgment of Rotation Direction

Determine the rotation direction of worm or worm wheel: erect the axis of worm wheel or worm, the helix is right-handed on the right side and left-handed on the left side.

Decide the turning: The right-handed rule is that the active worm is right-handed and grasps the worm with four fingers of the right hand along the turning direction of the worm. The thumb's direction is opposite to the direction of the node velocity of the worm wheel to determine the turning direction of the worm wheel.

If you want to judge the direction of a gear in hand, you can put the gear in front of you and see the direction of the gear. If the left is high and the right is low, it is left-handed. On the contrary, it is right-handed.

The determination of helical gear rotation direction:

Left-handed manipulation: left-handed with left hand, right-handed thumb and axial coincidence, four fingers pointed to the upward direction of the oblique teeth, left-handed coincidence is left-handed, right-handed coincidence is right-handed (always the back of the hand towards themselves).
