Description
Technical field
The invention belongs to nuclear power station service technique fields, and in particular to a kind of circular locking nut provision for disengagement.
Background technology
Two units of nuclear power station first stage of the project are respectively configured with five main feed pumps with model, the pump shaft both ends of model pump
It is each to be used for locking axle sleeve there are one circular locking nut to play the role of axially position.When carrying out dismounting work, due to circle
Shape locking nut is in irregular shape, forced area is small, acting force arm is short, along with corrosion, it is difficult to dismantle or
Person is installed in place, and when being overhauled every time to the type pump, dismantles the locking nut and always wastes the plenty of time.
Invention content
The object of the present invention is in view of the shortcomings of the prior art, provide a kind of simple in structure, round locking can effectively solve the problem that
The circular locking nut provision for disengagement for the problem of nut dismounting is difficult.
The technical scheme is that：
A kind of circular locking nut provision for disengagement, including rotating handle, tetrafluoro bushing, steel bushing and small boss, wherein tetrafluoro serves as a contrast
Set, steel bushing are hollow, and the steel bushing is placed on the outside of tetrafluoro bushing；One end of the steel bushing is uniformly distributed four small boss,
It is uniformly fixed on the outer wall of the steel bushing other end that there are four turning handles.
The internal orifice dimension of the steel bushing is identical with the outer aperture of tetrafluoro bushing, clearance fit.
Turning handle hole there are four being set on the steel bushing；The tetrafluoro bushing is set there are four turning handle hole.
Turning handle mounting hole on the steel bushing cooperates with the turning handle mounting hole on the tetrafluoro bushing, and each two corresponds to
Turning handle mounting hole fix a turning handle.
The beneficial effects of the invention are as follows：
1st, a kind of circular locking nut provision for disengagement of the invention is simple in structure, easy to use；
2nd, a kind of circular locking nut provision for disengagement of the invention can effectively solve the problem that the problem of locking nut dismounting is difficult,
And time saving, laborsaving, working efficiency is high；
3rd, there is tetrafluoro bushing in a kind of circular locking nut provision for disengagement of the invention, it will not be zero to pump shaft, nut etc.
Part causes to damage.

Specific embodiment
The present invention is further introduced with embodiment below in conjunction with the accompanying drawings：
A kind of circular locking nut provision for disengagement, including rotating handle 1, tetrafluoro bushing 2, steel bushing 3 and small boss 4, wherein four
Fluorine bushing 2, steel bushing 3 are hollow, and the steel bushing 3 is placed on 2 outside of tetrafluoro bushing；One end of the steel bushing 3 is uniformly distributed four
A small boss 4, uniformly fixed on the outer wall of 3 other end of steel bushing there are four turning handles 1.
The internal orifice dimension of the steel bushing 3 is identical with the outer aperture of tetrafluoro bushing 2, clearance fit.
Turning handle hole there are four being set on the steel bushing 3；The tetrafluoro bushing 2 is set there are four turning handle hole.
Turning handle mounting hole on the steel bushing 3 cooperates with the turning handle mounting hole on the tetrafluoro bushing 2, each two pair
The turning handle mounting hole answered fixes a turning handle 1.
Embodiment
The internal orifice dimension of steel bushing is identical with the outer aperture of tetrafluoro bushing, is clearance fit.Tetrafluoro bushing is put into steel bushing, hole
Device to hole cooperates, and four are rotated in handle advances through hole.Whole device is inserted on axis so that four semicircles of steel bushing one end
The small boss of key-like is inserted into corresponding groove on round nut.Rotating handle is turned counterclockwise or backs out round spiral shell with copper rod percussion
It is female.
