The invention relates to the technical field of lifting equipment, in particular to a lifting rod lead screw supporting transmission mechanism which comprises a base, a transmission mechanism, a driving mechanism, a lifting mechanism and an adjusting assembly, the transmission mechanism comprises a first chain wheel, a second chain wheel, a transmission chain, a first bearing, a bearing cover and a lead screw, and the driving mechanism works to drive the second chain wheel to rotate; the second chain wheel drives a lead screw on a first chain wheel to rotate through a transmission chain, the lead screw rotates to drive a lifting mechanism to ascend and descend, when the lifting mechanism inclines in the working process, the lifting mechanism pushes force to an inner ring of a first bearing, and the inner ring of the first bearing transmits the force to an outer ring of the first bearing through a plurality of balls and transmits the force to a base. The bearing cover applies downward pressing force and inward pressing force to the outer ring of the first bearing, force balance is achieved through the downward pressing force and the inward pressing force and upward lifting force and inward pushing force of the center of the base, and therefore the problem that an existing lead screw is too large in swing amplitude in the lifting process is solved through the effects.

    本发明涉及升降设备技术领域,具体涉及一种升降杆丝杆支撑传动机构,包括基座、传动机构、驱动机构、升降机构和调节组件,传动机构包括第一链轮、第二链轮、传动链、第一轴承、轴承盖和丝杆,驱动机构工作驱动第二链轮转动,第二链轮通过传动链带动第一链轮旋转上的丝杆转动,丝杆转动旋转带动升降机构升降,当升降机构在工作过程中发生倾斜时,升降机构将力推到第一轴承的内圈,第一轴承的内圈通过多个滚珠传递到第一轴承外圈上,并传递到基座上,轴承盖向第一轴承外圈施加向下压和向内压的力,与基座的中心向上举和向内推的力实现力平衡,通过以上作用,从而解决了现有的丝杆在升降过程中摆动幅度过大的问题。
