Summary of the invention
The purpose of this utility model is to provide radially compacting structure of a kind of rotating shaft, and it has the resilience of preventing function.
For achieving the above object, a kind of rotating shaft that the utility model provides is compacting structure radially, being intercalated at least one friction member by the cylindrical axostylus axostyle of an axis body forms, this axostylus axostyle surface is established one at least and is milled face, and friction member encloses corresponding to the non-isometrical and arc portion of contracting that be gradually-reducing shape of the circular arc part of axostylus axostyle external diameter and a section by one section and forms a ring body, it is tool one gap between the two, and central axis hole is for axostylus axostyle intercalation and ccontaining; Be subjected to the packing of arc portion of contracting by the axostylus axostyle circumference, and form the stagnation location, touch the arc portion free end that contracts when it mills face, then by the elastic return effect of this arc portion of contracting, axostylus axostyle is moved towards a certain direction, and make this mill face and this arc portion free end that contracts offsets, automatically lock and be.
Wherein this friction member is a lamellar body, and it can be via serial connection each other, and the hollow cylinder that is shaped.
The circular arc part of this friction member side extending one belled part in addition wherein, this belled part is to fall down shape, open its seat groove so that be intercalated in a side in the beam barrel seat, make friction member through serial connection and be fixedly arranged in the beam barrel, and then make each circular arc part reach the arc portion of respectively contracting to be coated by beam barrel.
Wherein the circular arc part free end internal diameter of this friction member must be slightly less than the axostylus axostyle external diameter.
