For speed reducer gearbox just want to clarify if i can use the worm gear side of the gearbox for the installation of drive motor instead of mounting it on the enveloping worm? what is the advantage and disadvantage
A worm drive.
Sand mullers break up sand after it has been used in molds to facilitate sandcasting. By effectively breaking up the sand, it can be reused. The worm on a motor or on the "driven" side of the device will engage with a worm gear. The worm rotates continuously, and the spiral cut gears "worm" their way "along" the axis of the gear. The worm gear (or spur gear) engages with the worm and rotates continuously as well. Also, the worm gear will translate the rotary motion of the worm by 90 degrees. It is fairly easy to see how the unit works if you look at some pictures or drawings. Hey, how about some animation or video? Got a couple of links.
Worm gear
You would use a worm drive meshed with a gear that has 130 teeth.
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
gear box or speed reducer.
A hobbing machine is used for cutting gear teeth in gear blanks and for cutting worm, spur, or helical gears.
The worm-gear design involves one helical gear, the teeth of which form segments of a helix, and another component that resembles a screw. The screw-like component is known as a worm, and its threads typically form a complete helix. This worm is typically used to drive the gear, which can provide a great deal of torque. In most cases, attempting to use the gear to turn the worm will result in the teeth locking. Both of these basics of worm gear-design can be exploited in the tuning knobs of stringed instruments, which provide the torque necessary to pull the strings taught and then automatically lock in place to keep them that way
The worm gear that runs it is stripped, Replace the motor.
the humming noise you are hearing is the gear inside of the headlight motor. there is a worm the motor turns, you chipped a tooth off of the motor. it won't read that the headlight is down, so it continues to turn until the override shuts it off. its a factory defect. Pontiac used a nylon motor to turn a metal worm. over time the worm wears the gear out. you have three options to fix it. one, replace the motor. two, take the motor out, take it apart rotate the gear inside the motor (only half the gear makes contact with the worm) so the other half of the gear is now used. it should be good for about another year after that. three, take out the motor break it apart and replace the nylon gear with a metal gear. if you take the motor apart, you need to epoxy it back together, the motor is not designed to be worked on. a new gear should cost about 50 dollars. a new motor should cost about 250. but it will have the same nylon gear in it. good luck.

Even slower
A worm or machine can be geared with worm gear to give it higher torque or to reduce rotational speed in the machine.
linear distance moved by the gear(worm,screw jack) for one rotation of the gear(worm,screw jack)
yes you can reverse worm and gear. A worm gear can rotate the worm, its based on the lead angle, pressure angle and co.efficient of friction between the pairs.
