Abstract: The present invention belongs to the field of mechanical transmission technology, and proposes a non-orthogonal elliptical toroidal worm gear pair, including an involute cylindrical gear and an elliptical toroidal worm formed by a primary envelope of the involute cylindrical gear; both adopt spatial non-orthogonal transmission, and the shaft angle satisfies the self-locking condition and the restriction condition of minimum tooth top width; the toroidal generatrix of the elliptical toroidal worm is elliptical, which can increase the number of meshing teeth and the total length of instantaneous contact line. A non-orthogonal elliptical toroidal worm gear pair proposed in this invention has the characteristics of toroidal worm drive and can realize the whole facewidth of the gear to participate in the meshing drive.

Abstract: A display substrate, a manufacturing method thereof, and a display device are provided. The manufacturing method of the display substrate includes: forming a pattern of first transparent conductive layer, forming a passivation layer and forming a second transparent conductive layer on the passivation layer, forming a pattern of second transparent conductive layer, i.e., a slit electrode, the pattern of second transparent conductive layer including a plurality of sub-electrodes arranged at intervals and located in a display region of the display substrate; and removing a portion of the passivation layer which is in the display region and is not covered by the sub-electrodes, forming a pattern of passivation layer. The second transparent conductive layer is polycrystalline ITO.
