Nuoguang processes ring worm gears, wheel worm gears, sector worm gears, copper worm gears, etc.

Shanghai Nuoguang processes worm gear accessories. Worm gear accessories include wheel type, ring type, sector type, copper worm gear, etc. Worm gear processing, a worm gear is a gear with a special tooth shape that meshes with the worm. The cutting of worm gear teeth is generally completed by a gear hobbing machine. There are two main methods: gear hobbing and flying knife cutting. Worm gears and worm gear mechanisms are often used in situations where two shafts are staggered, the transmission ratio is large, the transmission power is small, or the work is intermittent.
If you want to obtain a larger gear reduction ratio, you need to use a worm gear. The gear reduction ratio of the worm gear is generally , and sometimes even as high or greater.
Many worm gears have an interesting property not found in other gear sets. The worm can easily turn the gear, but the gear cannot turn the worm. This is because the angular angle on the screw is very shallow, and when the gear tries to rotate the screw, the friction between the gear and the screw keeps the screw in place.
Features of worm gear use
It can obtain a large transmission ratio, which is more compact than the staggered shaft helical gear mechanism
There is line contact between the meshing tooth surfaces of the two wheels, and its load-bearing capacity is much higher than that of the staggered shaft. Helical gear mechanism
and worm transmission are equivalent to screw transmission and are multi-tooth meshing transmissions, so the transmission is smooth, the noise is small
and it is self-locking. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism is self-locking and can achieve reverse self-locking, that is, the worm can only drive the worm gear, but not the worm gear. For example, the self-locking worm mechanism used in other heavy machinery has a reverse self-locking function for safety protection. However, the transmission efficiency is low and the wear is serious. When the worm gear is engaged in transmission, the relative sliding speed between the meshing gear teeth is large, so the friction loss is large and the efficiency is low. On the other hand, the relative sliding speed increases the tooth surface wear and heat seriously. In order to dissipate heat and reduce wear, more expensive materials with good friction reduction and anti-wear properties and good lubrication devices are often used, so the cost is high.
, the axial force of the worm is relatively large.
Shanghai Nuoguang Company has many years of experience in manufacturing worm gears. The worms range from single-head to six-head modules. The main materials are: (quenching), (carburizing and quenching). The tooth surface of the worm is precision ground by a thread grinder, and the tooth profile angle is detected by an optical projector, which greatly improves the transmission accuracy, reduces noise, and extends the service life. The worm gear is made of tin alloy copper (), aluminum alloy copper, and can also be made according to user requirements.
