High Transmission Ratio and Smooth Movement Worm Shaft And Worm Gear with Gear Hobbing

1)Description of Worm Gear Set

Worm gear is a gear mechanism for transmitting motion and power between two staggered axes, the worm is shaped like a screw

and the worm gear is similar to a helical cylindrical gear, and the two are meshed through helical teeth to realise the motion conversion,

and usually the worm is the active part.

2)Advantages of Worm Gear Set

• High transmission ratio: single-stage transmission ratio up to 10 - 80, can achieve a large reduction ratio in a compact space, to meet the demand for low speed and high torque.
• Smooth movement: the meshing process is a continuous helical tooth contact, low shock, vibration and noise, excellent transmission smoothness.
• Self-locking function: under certain conditions, the worm drive is self-locking, which prevents reverse motion and ensures the safety of the mechanical system.

3)Working Principle of Worm Gear Set

When the worm rotates, its helical teeth push the teeth of the worm wheel, converting the rotary motion of the worm into the rotary motion of the worm wheel.

For each revolution of the worm, the number of teeth of the worm wheel is equal to the number of heads of the worm, a

nd different transmission ratios can be achieved by adjusting the number of heads of the worm and the number of teeth of the worm wheel.

4)Application of Worm Gear Set

Commonly used in the feed system of machine tools, traction machine of lifts, steering mechanism of automobiles, lifting device of cranes,

etc., to achieve precise speed control and force transmission.
