In addition, use worm 42 drive worm wheel 41 to have the effect of province, and when worm 42 stopped rotating, possess the self-locking function to worm wheel 41 moreover, that is to say, worm wheel 41 received the rotation of external force and can not drive worm 42 rotation, and the practicality is strong, and this device of giving birth to is to the angle modulation of first bed board 2, convenient operation, simple structure answers simultaneously, design benefit uses pure mechanical structure moreover, and the reliability is high, and the durability is strong.

The worm gear 41 and the worm 42 have larger transmission ratio, and the spiral line of the worm 42 is meshed with the tooth surface of the worm gear 41. Since the lead angle of the worm 42 is small, the friction angle thereof is generally larger than the lead angle, which results in that when the worm wheel 41 receives a reaction force, the component direction of the friction force coincides with the direction of preventing the worm wheel from rotating, thereby achieving self-locking. In short, when the worm 42 stops rotating, the worm wheel 41 cannot drive the worm 42 to rotate due to the existence of friction, thereby achieving self-locking.

Labor-saving principle: the labor-saving principle of worm and gear transmission is mainly embodied on a larger transmission ratio. The gear ratio is the ratio of the number of teeth of the worm 42 to the worm wheel 41, and represents the number of turns of the worm 42 required for one revolution of the worm wheel 41. Because of the large transmission ratio, the worm 42 requires less torque, so that the force applied to the input end (such as the crank 43) is small, and the labor-saving effect is achieved. Meanwhile, the contact line speed of the worm gear is low, so that friction loss is low, and transmission efficiency is high.

In summary, the self-locking and labor-saving principles of the worm wheel 41 and worm 42 are mainly due to the meshing relationship, gear ratio and friction force between them. The transmission device is applied to the auxiliary delivery device for obstetrics and gynecology, so that the angle adjustment is convenient and labor-saving to operate, and the stability and safety of the device when the adjustment is required to be stopped can be ensured.
