The invention relates to the technical field of casters, in particular to a super-heavy load type universal caster which comprises a caster support, a wheel, a bearing, a lower ball assembly, an upper ball assembly and a connecting frame, a fixing seat is arranged at the top of the caster support, the connecting frame comprises a connecting shaft and a mounting plate, and the lower end of the connecting shaft is rotatably connected with the bottom of the fixing seat through the lower ball assembly; the top of the fixing seat is rotatably connected with the bottom of the mounting plate through an upper ball assembly, the bearing is embedded in a mounting groove of the fixing seat, the connecting shaft penetrates through a center hole of a bearing inner ring and the bottom of the mounting groove and is fixedly connected with the bearing inner ring, and a bearing outer ring is fixedly connected with the side wall of the mounting groove; the trundle support and the connecting frame are rotationally connected through the lower ball assembly, the bearing and the upper ball assembly, so that the rotating friction force between the connecting frame and the trundle support is smaller, the trundle is smoother and silent during steering, the pressure bearing performance and the balance performance of the steering part of the trundle are better, and the bearing capacity is higher.

    本发明涉及脚轮技术领域,具体是一种超重载型万向脚轮,包括脚轮支架、轮子、轴承、下滚珠组件、上滚珠组件和连接架,脚轮支架的顶部设有固定座,连接架包括连接轴和安装板,连接轴的下端与固定座的底部通过下滚珠组件进行可转动连接,固定座的顶部与安装板的底部通过上滚珠组件进行可转动连接,轴承嵌入安装在固定座的安装槽内,连接轴穿过轴承内圈的中心孔及安装槽底部并与轴承内圈固定连接,轴承外圈与安装槽侧壁固定连接;脚轮支架与连接架之间通过下滚珠组件、轴承、上滚珠组件进行转动连接,不但能够使连接架与脚轮支架之间的转动摩擦力更小,脚轮转向时更加顺滑静音,还能够使脚轮转向部位的承压性能和平衡性能更好,承载能力更强。
