In using pure polytetrafluoroethylene (PTFE) elastic hose elasticity modulus it is small, easily deform, thus can enable driving shaft well adapt to from
The position of moving axis and rotation precision are mechanically flexible coupling to realize.
In fact, in actual mechanical process, to keep the mechanical energy that is flexible coupling between driving link and driven member better
It adapts to, in assembly, makes the screw mounting hole on the pit and outer shaft of interior shaft to just, conduct being screwed in screw mounting hole
The top pressure screw of top pressure column makes interior shaft and outer shaft relatively unrotatable, and top pressure screw is then loosened 0.5-1 backward again
The case where enclosing, loosening is smart according to the processing of the transmission parts such as the concentricity and elastic hose of interior shaft and outer shaft and top pressure column
Du Laiding loosens a little less when interior shaft and outer shaft good concentricity and transmission parts high precision machining, and when driving shaft and from
When the concentricity of moving axis is inserted and transmission parts precision is low, loosen a little more.
Provided by the present invention to be mechanically flexible coupling, no need to increase right for the radial and axial size of interior shaft and outer shaft
Radial dimension and axial dimension requirement are relatively low, are particularly suitable for application and miniature flexible connection structure, overall structure is relatively easy, easily
In realization.
