worm pinion gear
Worm gears are generally used when large velocity reductions are actually needed. The reduction ratio depends upon the number of starts of the worm and number of teeth on the worm equipment. But worm gears have sliding call which is peaceful but will produce heat and also have relatively low transmission productivity.

For the materials for development, in general, worm is made from hard metal while the worm gear is made from relatively soft metallic such as for example aluminum bronze. That is since the number of teeth on the worm gear is relatively high compared to worm with its number of starts being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm teeth is decreased. Another characteristic of worm making may be the need of specialized machine for gear trimming and tooth grinding of worms. The worm gear, on the other hand, may be made out of the hobbing machine employed for spur gears. But as a result of the various tooth shape, it is not possible to cut many gears simultaneously by stacking the gear blanks as can be done with spur gears.

The applications for worm gears include gear boxes, fishing pole reels, guitar string tuning pegs, and where a delicate quickness adjustment by utilizing a huge speed reduction is necessary. When you can rotate the worm equipment by worm, it is generally extremely hard to rotate worm utilizing the worm gear. That is called the self locking feature. The self locking characteristic cannot always be assured and another method is recommended for true positive reverse prevention.

Also there is duplex worm gear type. When working with these, it is possible to change backlash, as when one’s teeth put on necessitates backlash adjustment, without needing a change in the center distance. There are not too many makers who can produce this type of worm.
EP’s worms and worm gears provide an efficient answer for power transmitting applications requiring high-ratio acceleration reduction in a restricted space using right angle (90°), nonintersecting shafts. When properly used, worms and worm gears supply the smoothest, quietest sort of gearing.
