The invention discloses a high-stability centrally-mounted motor adopting a planetary reducing mechanism. The high-stability centrally-mounted motor comprises a shell, a movement, the planetary reducing mechanism and a crankset positioning sleeve, wherein a middle shaft penetrates through the lower part of the shell; the movement, the planetary reducing mechanism and the crankset positioning sleeve are arranged in the shell; a core shaft of the machine core is connected with a planetary speed reducing mechanism, a planetary output wheel is fixedly or integrally arranged at the front end of a planetary carrier of the planetary speed reducing mechanism, a small gear is coaxially arranged on the planetary output wheel, and the small gear is meshed with a large gear sleeved on a crankset positioning sleeve through a one-way clutch. The chain wheel positioning sleeve is sleeved on the middle shaft, and the front part of the chain wheel positioning sleeve extends out of the shell to fix the chain wheel; the device is characterized in that a planet carrier is supported on a mandrel through a planet carrier bearing, the front part of the mandrel extends into the planet carrier to form a cantilever shaft, and a sun gear is arranged on the cantilever shaft and is meshed with a plurality of planet gears arranged in the planet carrier; and a central shaft which is coaxial with the central shaft is arranged on the planetary output wheel, and the central shaft is assembled in the shell through an output wheel bearing. The motor is better in operation stability, lower in noise, higher in working reliability and easy to assemble.

    本发明公开了一种采用行星减速机构的高稳定性中置电机,包括下部穿设中轴的壳体及设于壳体内的机芯、行星减速机构和牙盘定位套;机芯的芯轴与行星减速机构连接,行星减速机构的行星架前端固定或一体设有行星输出轮,其上同轴心设有小齿轮,该小齿轮同一通过单向离合器套于牙盘定位套上的大齿轮啮合;而牙盘定位套套于中轴上,其前部伸出壳体以固定牙盘;其特征在于行星架通过行星架轴承支撑设于芯轴上,芯轴前部伸入行星架内形成悬臂轴,悬臂轴上设太阳齿轮与设于行星架内的若干行星齿轮啮合;而行星输出轮上设有同芯轴共轴心的中心轴,该中心轴由输出轮轴承装配在壳体内。本发明运行稳定性更好,噪音更小,工作可靠性更高,且易于装配。
