Turbine Worm Drive Features

The worm mechanism is often used to transmit movement and power between the two staggered axes. The worm wheel and the worm are equivalent to gears and racks in its middle plane, and the worm is similar in shape to the screw.

The biggest feature of the worm worm transmission mechanism is that it has self-locking, which can play a good protective role on the equipment. The worm worm mechanism is often used in two-axis interleaving, transmission ratio is large, transmission power is not large work occasions, this kind of transmission mechanism is not suitable for long-term operation of the work.

The co-snail structure of the worm is generally active. The worm has the same right and left-handed parts as the thread, and is called the right-handed worm and the left-handed worm, respectively. There is only one spiral on the worm called a single worm, that is, the worm turn a week, the worm turn a tooth, if there are two spirals on the worm, it is called a two-headed worm, that is, the worm turn a week, the worm wheel turns two teeth.

The worm worm drive can get a large transmission ratio and is compact, small in size and light in weight. Because the worm teeth are continuous spiral teeth, and the worm teeth are continuous when meshing, the worm teeth do not enter and exit the process of meshing, so the work is smooth, impact, vibration, noise is relatively small. The spiral angle of the worm is very small, the worm can only drive the worm wheel transmission, and the worm wheel can not drive the worm rotation, has a good self-locking. It should be noted that the efficiency of the worm drive is low, the tooth surface is easy to wear, the heat is large, the cost is high. Nine Positive hardware network small editor think that can sum up the following points:

1. transmission ratio is large, compact structure

2. smooth transmission, no noise

3. with self-locking

4. low transmission efficiency, more serious wear

5. the worm axial force is larger, resulting in a large loss of bearing friction
