The invention provides a differential bearing device of a robot trolley. The differential bearing device of the robot trolley comprises a motor, wheels and a speed reducer. The motor is used for driving the wheels through the speed reducer. The differential bearing device of the robot trolley further comprises a connecting body, a radial bearing and a wheel bearing connecting piece. The connecting body has a connection body bore and is secured to a housing of the speed reducer. The radial bearing is embedded into an inner hole of the connecting body, and an outer ring of the radial bearing is fixed to the inner hole of the connecting body. The axial outer side portion of the wheel bearing connecting piece is fixedly connected to the wheel, and the axial inner side portion of the wheel bearing connecting piece is partially inserted into the inner ring of the radial bearing and fixedly connected to the output shaft of the speed reducer. The differential bearing device of the robot trolley transmits radial force from wheels to the connecting main body through the radial bearing, so that the radial force of the output shaft of the speed reducer is reduced.

    提供了一种机器人小车差速承载装置,该机器人小车差速承载装置包括电机、车轮和减速器。其中,电机用于经由减速器驱动车轮。其中,机器人小车差速承载装置还包括连接主体、径向轴承以及车轮承载连接件。连接主体具有连接主体内孔并且固接到减速器的外壳上。径向轴承嵌入连接主体内孔中,径向轴承的外圈固定于连接主体内孔。车轮承载连接件的轴向外侧部固接到车轮,车轮承载连接件的轴向内侧部部分地插入径向轴承的内圈中并固接到减速器的输出轴。该机器人小车差速承载装置将来自车轮的径向力通过径向轴承传递给连接主体从而减少减速器的输出轴的径向力。
