Processing of small module worm gears, ring worm gears and multi-head worms Shanghai Nuoguang

Shanghai Nuoguang processing accessories ring worm gear, small module worm gear, wheel worm gear, sector worm gear, copper worm gear and single-head worm, double-head worm, three-head worm and multi-head worm processing, the pairing of worm gear and worm is in its middle plane Equivalent to gears and racks, worms are similar in shape to screws. The mechanism is often used to transmit motion and power between two staggered shafts. 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. 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.

Shanghai Nuoguang Manufacturer provides supporting processing. Our factory has always adhered to the principle of quality as the foundation and customer first. The price is reasonable and the goods are shipped quickly. We welcome drawings and samples for processing. The production process includes sand casting, metal casting, centrifugal casting, precision casting, pressure casting, vacuum casting, and forging, which can provide finished products, semi-finished products, and blanks. Our 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, 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.
Characteristics of worm gear accessories
It can obtain a large transmission ratio and 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-axis helical gear mechanism.
Worm transmission is equivalent to screw transmission and is a multi-tooth meshing transmission, so the transmission is stable and the noise is small.
, 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 lifting machinery has a reverse self-locking function that can provide safety protection.
, 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.
