Film trap, plays anti-loose effect.Limited by operator's level, locking effect differs greatly.Need to be by locking plate when needing to back out nut
Destructive decomposition, assembles more renew locking plate again, the not reproducible use of locking plate.
The content of the invention
The embodiment of the present invention provides a kind of retaining mechanism of shaft end nut, poor to solve existing shaft end nut locking effect
And the not re-usable problem of locking member.
The present invention provides a kind of retaining mechanism of shaft end nut, including：Shaft locking piece, nut check piece and block, it is described
Shaft locking piece and axis are clamped, and the nut check piece is clamped with nut, block be connected respectively with shaft locking piece, nut check piece with
Realize the locking of shaft end nut.
In the retaining mechanism of the shaft end nut of the present invention, the shaft locking piece is in circular ring shape, along the shaft locking piece
It is axially arranged with least two axis lock ears, the axis lock ear is inserted into the shaft locking groove of the axial end；
Two boss are equipped with the outer circumference surface of the shaft locking piece, are formed between two boss being oppositely arranged described in supplying
The block groove of block one end insertion, is equipped with screw hole in the boss and block correspondence position, can be consolidated block one end by bolt
Surely arrive in block groove.
In the retaining mechanism of the shaft end nut of the present invention, the nut check piece is in circular ring shape, along nut check piece
Radially and at least two nut lock ears are equipped with to center of circle direction, the nut lock ear is caught in the nut check groove of the nut end face
It is interior；
Be uniformly provided with serrated slot on the outer circumference surface of the nut check piece, the other end of the block be equipped with it is described
The sawtooth that serrated slot coordinates, described block one end are bolted in block groove, and the other end passes through sawtooth and nut check
The serrated slot engagement of the side face of piece, to realize the locking of shaft end nut.
In the retaining mechanism of the shaft end nut of the present invention, three axis lock ears are axially arranged with along the shaft locking piece.
In the retaining mechanism of the shaft end nut of the present invention, three nut locks are radially provided with along the nut check piece
Ear.
In the retaining mechanism of the shaft end nut of the present invention, the maximum width L of the serrated slot meets following relationship：Wherein r is the radius of nut check piece.
The present invention a kind of shaft end nut retaining mechanism using Split type structure design, using block realize shaft locking piece with
The connection of nut check piece, locking is cooperatively formed by the serrated slot on the sawtooth on block and nut check piece side face, locking
Effect is good and retaining mechanism repeats utilization.
Shaft end nut locking operation is carried out using the retaining mechanism of the present invention, the level of skill requirement to operator is relatively low,
Locking effect and reproducible, solves since operator's level of skill and locking effect difference caused by working attitude difference are asked
Topic.
