Description
Technical field
The utility model belongs to mechanical automation device field, and in particular to a kind of isolator.
Background technology
One-way clutch, abbreviation isolator, be in engine starting process with the matching used important component of starter.
Generally unidirectionally clutch is the intermediate member transmitted by driving shell as power, and in isolator clutch, hollow shaft is
The vital part of one composition one-way clutch.The driving shell and helical spline of one-way clutch are each provided in hollow shaft.It is existing
Some hollow shafts are usually made of continuous three sections, and first segment is one-way wheel bar, and the second section is connecting rod, and third section is sliding tooth
Bar, wherein first segment and the second section are hollow section, and bushing is set in the section of the second section.Since the third section of this hollow shaft is envelope
Shape is closed, when leading to be installed on telescopic movable of the drive rod of one-way clutch in hollow shaft in the axis of hollow shaft, can be produced
A raw piston effect causes the stretching motion of drive rod to be blocked up by gas and influence isolator and the flexible of engine flywheel is nibbled
Conjunction process.
In view of above-mentioned deficiency, now needs a kind of isolator, the gas generated due to piston effect can be eliminated and block up phenomenon, improve one
The service life of kind isolator.
Utility model content
The purpose of this utility model provides a kind of isolator, can eliminate the gas generated due to piston effect and block up phenomenon, improves
A kind of service life of isolator.
The utility model provides following technical solution：
A kind of isolator including a kind of hollow shaft of isolator, is made of continuous three sections, and first segment is one-way wheel bar,
Second section is connecting rod, and third section is driving ratch, wherein the one-way wheel bar and the connecting rod are hollow section, the connection
Setting bushing in the section of bar, the driving ratch center are equipped with venthole, support element, the support element are equipped in the venthole
Cross section to be cellular, the peripheral edge of the support element connects with the interior wall seamless of the venthole, it is described it is a kind of unidirectionally
The hollow shaft periphery of device is also coated with nano-ceramic layer.
Preferably, the nano ceramics layer thickness is 2 to 3 millimeters.
Preferably, the support element is interwoven by several cylinder materials.
Preferably, the support element is integrally formed.
Preferably, the support element uses roller bearing steel.
The beneficial effects of the utility model：
The utility model increases venthole by the third section in hollow shaft, makes to be installed on the one-way clutch in hollow shaft
The drive rod of device during stretching motion, eliminates the gas generated due to piston effect and blocks up phenomenon, and pass through support element in hollow shaft
Bracing reinforcement, further improve a kind of service life of isolator.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not form the limitation to the utility model together.In the accompanying drawings：
Fig. 1 is the utility model section view；
Fig. 2 is vent hole structure figure.
In figure label for：1st, one-way wheel bar；2nd, connecting rod；3 driving ratch；4th, venthole；5th, support element.
Specific embodiment
As shown in Figure 1 to Figure 2, a kind of isolator including a kind of hollow shaft of isolator, is made of continuous three sections, the
For one section for one-way wheel bar 1, the second section is connecting rod 2, and third section is driving ratch 3, during wherein one-way wheel bar 1 is with connecting rod 2
Sky saves, setting bushing in the section of connecting rod 2, and 3 center of driving ratch is equipped with venthole 4, and venthole 4 is interior to be equipped with support element 5, support
To be cellular, the peripheral edge of support element 5 connects with the interior wall seamless of venthole 4 for the cross section of part 5, a kind of isolator it is hollow
Axis periphery is also coated with nano-ceramic layer；Ratch 3 is driven to increase venthole 4 by the third section in hollow shaft, make to be installed on
The driving ratch 3 of one-way clutch in hollow shaft during stretching motion, eliminates what is generated due to piston effect in hollow shaft
Gas blocks up phenomenon, improves a kind of service life of isolator；And by the bracing reinforcement of support element 5, and cellular support element 5
Stability is good, and nano-ceramic layer is wear-resisting, firm, can further improve a kind of service life of isolator；Nano ceramics layer thickness
It it is 2 to 3 millimeters, the nano-ceramic layer of this thickness is wear-resisting and toughness is excellent；
Wherein, support element 5 is interwoven by several cylinder materials, and column structure is stablized, and can improve support element stability；
Support element 5 is integrally formed, and integrated molding can further improve 5 stability of support element；Support element 5 uses roller bearing steel, rolling
Dynamic bearing steel toughness is good.
The advantages of the utility model：
As depicted in figs. 1 and 2, venthole 4 is increased in the third section of hollow shaft driving ratch 3, makes to be installed on hollow shaft
The driving ratch 3 of interior one-way clutch during stretching motion, eliminates the gas generated due to piston effect and blocks up now in hollow shaft
As improving a kind of service life of isolator；And by the bracing reinforcement of support element 5, and 5 stability of cellular support element
Good, nano-ceramic layer is wear-resisting, firm, can further improve a kind of service life of isolator.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
It modifies to the technical solution recorded in foregoing embodiments or equivalent replacement is carried out to which part technical characteristic.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
