The invention discloses a gearbox structure for an electric long slide rail, which comprises a box body, an input gear shaft, an intermediate gear shaft and a transmission gear shaft are arranged in the box body, an input gear is arranged on the input gear shaft, an intermediate gear is arranged on the intermediate gear shaft, the input gear is meshed with the intermediate gear, and the transmission gear shaft is meshed with the intermediate gear. The transmission gear shaft comprises a gear part and a spline part which are of an integrated structure, the gear part is located in the box body, a transmission gear meshed with the intermediate gear is arranged on the gear part, the spline part extends out of the box body, an output gear is connected to the spline part, and the output gear is connected with the transmission gear. The output gear is connected with the spline part through a spline in a matched mode. And not only can the stable operation of the long sliding rail be realized, but also the transmission clearance of the gear box is reduced to the greatest extent.

    本发明公开了一种用于电动长滑轨的齿轮箱结构,包括箱体,所述箱体内设有输入齿轮轴、中间齿轮轴和传动齿轮轴,所述输入齿轮轴上设有输入齿轮,所述中间齿轮轴上设有中间齿轮,所述输入齿轮与中间齿轮啮合,所述传动齿轮轴包括一体结构的齿轮部及花键部,所述齿轮部位于所述箱体内,所述齿轮部上设有与所述中间齿轮啮合的传动齿轮,所述花键部伸出所述箱体外,所述花键部上连接有输出齿轮,所述输出齿轮与所述花键部通过花键配合连接。不仅能实现长滑轨平稳运行,而且在最大程度上减少了齿轮箱自身的传动间隙。
