Worm Gear
product manual
Turbine shaftWhat are the characteristics?
1. The worm drive is equivalent to a spiral drive and is a multi-tooth meshing drive, so the transmission is stable and the noise is small.
2. 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 means that tooth surface wear is serious and heat is serious. In order to dissipate heat and reduce wear, more expensive materials with better anti-friction and anti-wear properties and good lubricating devices are often used, so the cost is higher. .
3. A large transmission ratio can be obtained, which is more compact than a cross-axis helical gear mechanism.
4. The axial force of the worm gear is larger.
5. The meshing tooth surfaces of the two wheels are in line contact, and its carrying capacity is much higher than that of the cross-axis helical gear mechanism.
6. The worm gear is self-locking.When the lead angle of the worm is smaller than the equivalent friction angle between the meshing gear teeth, the mechanism is self-locking and can realize reverse self-locking, that is, the worm can only be driven by the worm wheel, and the worm cannot be driven by the worm wheel.For example, the self-locking worm mechanism used in hoisting machinery, its reverse self-locking property can play a safety protection role.
