Worm gear transmission is a transmission that changes the transmission direction. Due to the large pressure, severe friction, and large heat generated during the force transmission process, in order to prevent gluing, in the selection of materials, due to the low speed of the worm wheel, softer alloy materials are often used, while the worm Choose stronger steel materials.
Whether the installation of the worm gear is qualified:
The installation of the worm wheel and the worm must consider the coincidence of the center plane of the worm wheel and the worm axis, otherwise it will cause the worm wheel to be unbalanced and cause serious partial wear and shorten the life of the parts. Worm gears only need to rotate in the same direction to meet the touch. (The thread should be placed next to the cylinder and then investigate). Right-handed means that the right side is higher than the left and grows upward, and left-handed means that the left side is higher than the right side and grows upward. The force is essentially the kneading force of the inclined plane. The self-locking condition is that after the inclination angle of the inclined surface is small to a certain degree, the friction force of the pressure is greater than the inclined surface component force, and it cannot roll under this kind of pressure condition.
The direction of rotation of the worm is easy to judge. Stand the worm to see which side of the helix is high. The height on the left side is left-handed, and the height on the right side is right-handed. The left hand is used for left-hand rotation, and the right hand is used for right-hand rotation. The bending direction of the four fingers is the direction of rotation of the worm, and the direction of the thumb is the direction of rotation of the worm wheel. vice versa.
To measure the installation error between the center plane of the worm wheel and the center axis of the worm, use a standard ruler against the side surface of the worm wheel, and then measure the distance between the ruler and the worm. If the distance between the four side surfaces of the worm wheel and the worm is equal, then It can be in a plane, if the measured distance between the four side surfaces does not exceed the allowable error, the installation can be qualified.
The above is the summary of worm gear manufacturers for everyone, I hope it can be helpful to everyone!
