Minority lossless manner is only had to be difficult to invariably adopt rotating shaft snap-type formula on the market, external member is rotated owing to it exists, the diameters of its turning axle etc. directly occupy the space in the radius direction of very big ratio, requiring space higher operating mode cannot be applied, and then proposing a kind of face contact type self-adaptive non-loss with certain adaptivity and fill securing gear soon.
Summary of the invention
In view of this, the utility model provides a kind of face contact type self-adaptive non-loss and fills securing gear soon, can in the extremely finite space, to inner supporting axis/pipe without the need to any mechanical workout, face contact can be utilized to produce squeeze, producing certain displacement deformation, and can have certain adaptivity within the specific limits, having integral type can the feature of Fast Installation; The utility model can meet and carries out the fastening requirement of high reliability, cycle long lifetime under the complex working conditions such as high pressure, high temperature, highly corrosive, shock and vibration and in the extremely finite space.
Realize specific embodiments of the present utility model as follows:
A kind of face contact type self-adaptive non-loss fills securing gear soon, and its peripheral unit is supporting axis or pipe, comprising: eccentric cylinder, two eccentric wedge keys, stop screws;
Described eccentric cylinder is a circular ring structure, and the inner peripheral surface at the two ends of annulus processes one section of arc, and it is on the eccentric hole of s that described arc is positioned at circle ring center axis angle; The both ends of the surface of described eccentric cylinder are provided with threaded hole;
Described eccentric wedge key comprises wedge-shaped part and connecting wing, wherein wedge-shaped part is the structure matched in the gap that in eccentric cylinder, space is formed with fastened axle or pipe, the thickness of wedge-shaped part m bigger than the thickness in this gap, connecting wing is provided with the corresponding threaded hole in the threaded hole position with eccentric cylinder;
Two described eccentric wedge keys are respectively from the two ends wedging eccentric cylinder of eccentric cylinder symmetry and the space folded by fastened axle or pipe, and stop screw all connects the threaded hole of connecting wing and the threaded hole of eccentric cylinder of described bias wedge key.
Further, the inner peripheral surface of described eccentric cylinder is processed with two with the threaded hole of central shaft symmetry.
Further, s=8 �㡫15 ��.
Further, m=0.03mm��0.05mm.
Further, the eccentric outer circumference surface of wedge key is added with the corresponding spring fitting groove in position with the inner peripheral surface of eccentric cylinder, and spring is arranged in the space of installation groove formation of eccentric wedge key and eccentric cylinder by compression.
Useful effect:
(1) inner supporting axis/pipe is not needed to do any processing, directly install, it is achieved can't harm technique, avoid screw-type etc. to the destruction of the safeguard procedures such as antifouling paste;
(2) inside and outside eccentric wedge key, mating surface is face contact, avoids usual wedge key line and coordinates that the local stress produced is big, rub big, perishable defect;
(3) size is relatively minimum, processing disposal molding, it is possible to avoid the turning axle of split button, it is possible to adapting to the installation control of the extremely finite space, the intensity under kindred circumstances is far longer than split button;
(4) eccentric wedge key has certain adaptivity, and when being corroded at internal support axle/pipe or produce roughness equal diameter error because of painting anticorrosion paint, eccentric wedge key and eccentric cylinder can show error compensation, still can have certain adaptability;
(5) only eccentric wedge key need to be wedged eccentric cylinder when installing, simple to operate, rapidly; Replaceable, the property grasped is strong;
(6) owing to securing gear is in vibration state for a long time, it is easy to cause screw loosening, the installation of this spring is the natural frequency by changing whole device, avoids securing gear to lose efficacy due to loosening of screw.
