Helical worm gearmotor using a worm gear and worm can get large transmission ratio, compact than interlaced helical gear mechanism for line contact between the two gear tooth surface, its carrying capacity and much higher than the interlaced helical gear mechanism, worm drive is equivalent to the spiral transmission, multiple tooth meshing transmission, so the stable transmission, noise is small, with self-locking. When the lead Angle of the worm is less than the equivalent friction Angle between the meshing teeth, the mechanism has self-locking and can realize reverse self-locking, i.e. it can only be driven by worm gear, and can not be driven by worm gear. If the self-locking worm mechanism is used in its heavy machinery, its reverse self-locking can play a safe and protective role. The transmission efficiency is low, the wear is more serious. When the worm gear meshing drive, the relative sliding speed between the meshing teeth is large, so the friction loss is large and the efficiency is low. Relative sliding velocity, on the other hand, ambassador of tooth surface wear serious, fever, in order to heat and reduce the wear and tear, often using relatively expensive antifriction and wear resistance of good material and good lubrication device, so the high cost, worm axial force is larger.
