The invention provides a multi-connected screw transmission mechanism and a guide rail assembly, which are used to solve the problem of relatively limited screw and nut transmission in the prior art. A multi-connected screw transmission mechanism, comprising: a screw, the screw includes: a rod body, threads arranged on the peripheral surface of the rod body, and a plurality of axial tooth grooves, the plurality of axial tooth grooves are arranged in the circumferential direction, etc. It is arranged at intervals and divides the thread to form several meshing teeth, and the side of the meshing teeth close to the axial tooth groove is the first tooth surface; the multi-connected screw transmission mechanism also includes at least one first nut assembly, and the first A nut assembly is mounted on the screw through thread fit; the multi-connected screw transmission mechanism also includes at least one first gear, and the first gear is used to mesh with the meshing teeth to form a rotation transmission pair, and the first The meshing surface of the gear is the second tooth surface, and the width of the second tooth surface is greater than the pitch of the thread; the multi-connected screw transmission mechanism also includes a speed change mechanism. A variety of different axial movements can be realized.
Description
technical field [0001] The invention relates to the field of screw transmission, in particular to a multi-connected screw transmission mechanism and a guide rail assembly. Background technique [0002] There are many types and models of screw drive products, which are widely used in all walks of life. However, there is generally only one nut on a screw for transmission, or when multiple nuts are placed on one screw, the direction and speed of each nut transmission are the same, and it is impossible to realize that one screw drives multiple nuts at different speeds and in different directions. the transmission effect. [0003] And the track of the curtain in the prior art can only be opened and closed in one direction, and the edge of the curtain is moved during the switching process, resulting in uneven force, affecting the life of the curtain, and the motor's motion power is relatively large, causing noise. Various issues. Contents of the invention [0004] In view of ...
