The working environment totally lubricated is remained, reduces the abrasion of torsion spring, improves the job stability of isolator.
The technical solution adopted in the utility model is as follows：A kind of isolator for vehicle starter structure, including sleeve, sleeve
One end equipped with splined shaft is head end, and its other end is tail end, and the middle part of sleeve has the installation end face for being used for installing gear, its
It is characterised by, installation end face includes the first end face of the head end close to sleeve, and the second end face of the head end away from sleeve, the
The 3rd end face is provided between end face and second end face, chip removal is equipped between the 3rd end face and first end face and second end face
Groove, first end face, second end face and the 3rd end face are recessed arc-shaped curved surface.
Due to the setting of said structure, the arc-shaped curved surface that first end face, second end face and the 3rd end face are recessed can
To reduce the displacement of sealing ring and torsion spring on sleeve axis direction, sealing ring tightly can be attached on sleeve, and then is prevented
External dust or mud enter in the fit clearance of sleeve and gear, the interface of torsion spring and barrel contacts is remained clean profit
Sliding working environment, reduce the abrasion of torsion spring, improve the job stability of isolator；The setting of chip area can collect
Caused abrasive dust on end face, second end face and the 3rd end face, prevent abrasive dust from running helter-skelter everywhere and combine to form grease with lubricating fluid
And increase the coefficient of friction between gear and sleeve, particularly increase the coefficient of friction between torsion spring and sleeve, play timely row
The effect of bits, further reduce the abrasion of torsion spring.
Further, in order to reduce the abrasion between sleeve and sealing ring and gear, its contact area is increased, first end face,
The marginal end of second end face and the 3rd end face is equipped with mounting platform, and mounting platform has the curved surface parallel to sleeve axis, peace
The width of assembling platform is not less than 2mm.
Further, in order to improve the chip removal effect of chip area, the depth of chip area is not less than 2mm, and its A/F is not small
In 3mm.
In order to further reduce the abrasion between sleeve and sealing ring and gear, the radian of the arc-shaped curved surface of the 3rd end face is not
More than π/36, the radian of the arc-shaped curved surface of first end face and second end face is not more than π/18.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：By improving isolator
Sealing and set chip area, on the one hand prevent outside dust or mud by gap enter torsion spring in, on the other hand
By excluding caused abrasive dust in isolator work in time, the interface of torsion spring and barrel contacts is set to remain the work totally lubricated
Make environment, reduce the abrasion of torsion spring, improve the job stability of isolator.
