The invention discloses a three-shaft short-circuit line transmission speed reducer which comprises a box body and a box cover which are fixedly connected, a driving gear shaft which extends into the box cover and the box body and is supported on the box cover, a speed reduction carrier gear shaft which is supported in the box cover and the box body and is arranged below the driving gear shaft, and a low-speed driven gear shaft which extends into the box body and is supported on the box body, the speed reduction carrier gear shaft is in speed reduction transmission connection with the driving gear shaft, the low-speed driven gear shaft is in low-speed transmission connection with the speed reduction carrier gear shaft, a bearing cavity is formed in the inner end of the low-speed driven gear shaft, the inner end of the driving gear shaft is installed in the bearing cavity through a bearing, and the driving gear shaft and the low-speed driven gear shaft are coaxial. Only three transmission shafts are adopted, the transmission route is short, the structure is compact and simple, the meshing accumulative error is small, after low-torque and high-speed transmission input is conducted on the driving gear shaft, high-torque and low-speed transmission output is conducted through the low-speed driven gear shaft coaxially arranged with the driving gear shaft finally, and compared with the prior art, the height size of the speed reducer box is greatly reduced.
本发明公开了一种三轴短路线传动的减速机,包括固定连接的箱体与箱盖、伸进箱盖与箱体内并支承在箱盖的主动齿轴、支承在箱盖与箱体内且布置在主动齿轴下方的减速过桥齿轮轴和伸进箱体内并支承在箱体的低速从动齿轮轴,减速过桥齿轮轴减速传动连接主动齿轴,低速从动齿轮轴低速传动连接减速过桥齿轮轴,低速从动齿轮轴的内端开设轴承腔,主动齿轴其内端通过轴承安装在轴承腔中,主动齿轴与低速从动齿轮轴共轴线。本发明仅采用三条传动轴且传动路线短,结构紧凑简洁,啮合累积误差小,其中的主动齿轴低扭矩、高速传动输入后,最终通过与主动齿轴共轴线排布的低速从动齿轮轴以高扭矩、低速传动输出,减速机箱的高度尺寸与现有技术相比大为压缩。
