The invention provides a steering device, a steering wheel and a robot, and relates to the technical field of AGV structures. The steering device comprises a protective shell, a slewing bearing, a dynamic sealing piece and a first sealing ring, wherein the protective shell comprises a mounting plate and a cover, the mounting plate and the cover form an accommodating cavity, and a through hole is formed in the middle of the mounting plate; the slewing bearing is arranged in the accommodating cavity, and an inner ring of the slewing bearing is mounted on the mounting plate; the dynamic sealing piece is used for filling a gap between the cover and the outer ring of the slewing bearing to enable the outer ring of the slewing bearing to be in dynamic sealing fit with the cover; and the first sealing ring is annularly arranged in the through hole to fill a gap between the mounting plate and the inner ring of the slewing bearing so as to enable the inner ring of the slewing bearing to be in sealing fit with the mounting plate. On the premise that the boundary dimension of the steering device is not excessively increased, the upper part and the lower part of the whole slewing bearing are both connected with the outside in a sealed mode, and thus the IP55 waterproof and dustproof level can be better achieved on the whole.
本申请提供一种转向装置、舵轮和机器人,涉及AGV小车结构技术领域。转向装置包括保护壳、回转支承、动态密封件和第一密封圈。保护壳包括安装板和盖,安装板和盖形成容纳腔,安装板中部具有通孔。回转支承设置于容纳腔中,且回转支承的内圈安装于安装板。动态密封件用于填充盖与回转支承的外圈之间的缝隙使回转支承的外圈与盖动态密封配合。第一密封圈环设于通孔以填充安装板与回转支承的内圈之间的缝隙使回转支承的内圈与安装板密封配合。本申请在并未过多增大转向装置的外形尺寸的前提下,使整个回转支承的上部和下部均与外界密封连接,从而有利于整体达到IP55防水防尘等级。
