同轴模块化多轴旋转机构的研制

Development of Coaxial Modular Multi Axis Rotating Mechanism

为了解决因立柱直径与回转支承内径尺寸之间相互制约,而造成的多层旋转LED屏旋转机构的承载能力弱、回转支承选型过大的问题,设计了一种基于内外双立柱的同轴模块化多轴旋转机构;每个旋转机构模块由动力装置、内立柱、外立柱、回转支承、底座、滑环等组成。此机构将设备所承受的载荷,分配至不同的构件,由外立柱承受风载、重力等主要载荷,内立柱仅承受用于旋转的扭力载荷。通过对载荷的分配,有效解决了立柱直径与回转支承内孔之间相互制约的问题,使回转支承的规格趋于合理化,极大地提高了同等外形尺寸旋转机构的承载能力。

In order to solve the problems of weak bearing capacity of multi-layer rotating LED screen rotating mechanism and excessive selection of slewing ring caused by the mutual restriction between column diameter and slewing ring inner diameter,a coaxial modular multi axis rotating mechanism based on inner and outer double columns is designed;Each rotating mechanism module is composed of power unit,inner column,outer column,slewing ring,base,slip ring,etc.This mechanism distributes the load borne by the equipment to different components.The outer column bears the main loads such as wind load and gravity,and the inner column only bears the torsional load for rotation.Through the load distribution,the mutual restriction between the column diameter and the inner hole of the slewing bearing is effectively solved,the specification of the slewing bearing tends to be rationalized,and the bearing capacity of the rotating mechanism with the same overall size is greatly improved.
