Worm gear

Worm and worm wheel mechanism 1 can get great ratio than crisscross helical gear mechanism compact 2. Two gear tooth surface for line contact, its carrying capacity than crisscross helical gear axle 3 worm transmission, which is equivalent to screw transmission gear meshing smooth transmission, therefore, the noise is small 4 with self-locking sex. When the worm gear meshing Angle between process is less than the equivalent friction Angle, institution, with self-locking can reverse self-locking, namely, only by the worm drive worm gear and worm drive not by. As in the heavy machinery in use, the worm self-locking reverse self-locking sex can be protected. 5 the transmission efficiency, low wear more serious. Worm gear and worm gear transmission gears, the relative speed between gear sliding friction loss is big, big and low efficiency. On the other hand, the relative sliding speed ambassador tooth surfaces wear serious, fever, in order to reduce heat and wear, often USES the price is relatively high abrasion resistance coefficient and better materials and good lubrication device and higher cost 6 worm axial force
