What is the function of a worm gear mechanism?

The worm gear mechanism consists of a worm gear and a worm gear, with the worm gear resembling a helical gear and the worm gear resembling a screw. The worm gear rotates once, and the worm gear also rotates a certain angle accordingly. On the contrary, the worm gear rotates, and due to the small helix angle of the worm, the worm will not rotate along with it. This is the important characteristic of the worm gear mechanism, which is its self-locking characteristic.

Main characteristics of worm gear and worm gear mechanism:
1. The transmission ratio is large.
2. Under the same transmission ratio, the structure is compact and the volume is small.
3. Self locking feature.
4. It can transmit motion at right angles. Because the two shafts of a worm gear drive intersect and are perpendicular to each other.
5. The worm gear and worm gear are in line contact with each other, so their load-bearing capacity is large.

From the main characteristics above, it can be inferred that its function is:
1. It is commonly used as a worm gear reducer in various industries: turntables or turntables, batching systems, automatic feeding machinery, stackers, belt conveyors, farm picking trucks, and more automation industries.
The worm gear of the elevator also serves as a fault safety auxiliary braking system.
3. Utilize self-locking characteristics for safety doors.
4. The tuning mechanism on string instruments such as guitar, double bass, banjo, and violin.
5. The indexing plate on the machine tool.
6. Some measuring equipment.
