Abstract

The invention discloses a worm transmission mechanism. The worm transmission mechanism comprises a transmission shaft and a worm. A transmission gear sleeves the transmission shaft. The external surface of the transmission gear is provided with gear slots. The external surface of the worm is equipped with threaded slots. The threaded slots are butt joint with the gear slots and engage with the gear slots. The worm is externally connected to a driving motor, and the rotation control over the worm is realized by the driving motor, so the transmission gear can move by means of the threaded slots and the gear slots and then the transmission shaft is controlled to rotate.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a worm transmission mechanism. Background technique [0002] Worm drive is a kind of transmission that transmits motion and power between two axes that are interlaced in space. The angle between the two axes can be any value, and the commonly used one is 90°. Worm drives are used to transmit motion and power between staggered shafts. The existing worm transmission mechanism has poor stability during rotation. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing an external drive motor for the worm, through which the rotation of the worm can be controlled by the drive motor, so that the transmission gear can be moved conveniently through the thread groove and the tooth groove, and the transmission shaft can be controlled Rotating worm drive. [0004] Above-mentioned technical problem of the presen...
