Abstract
The utility model discloses a connecting rod dust cover, including ball round pin seal port, dustproof cover body wall and ball key seat seal port, the maximum diameter department on dustproof cover body wall outer wall is equipped with the die parting line circle. The utility model discloses beneficial effect is obvious: establish the die parting line circle in the dust cover main part, can avoid the fracture of dust cover inner wall when vulcanization molding, improve the quality of dust cover, prolong the life of dust cover, improve effect dustproof, muddy water preventing.
Description
Technical field
The utility model belongs to manufactruing equipment of automobile technical field, relates to a kind of rubber seal, is specifically related to a kind of connecting rod dust cover.
Background technology
In the power unit of motor vehicle, between the connector of motion transmission, adopt dust cover to carry out dust seal more. Existing dust cover adopts natural rubber more, and the dust cover having in manufacturing process can produce slit cracking, and rubber cracking place can produce some slits, although sometimes with visually observe less than, in long-term fierce motion process, due to quality dissatisfaction; The dust cover breakage of can ftractureing, dust-proof effect is poor, and motion transmission is produced to harmful effect.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of connecting rod dust cover.
The technical solution adopted in the utility model is:
A kind of connecting rod dust cover, comprises ball pin seal, dust cover body wall and ball pin seat seal, and the maximum gauge place on dust cover body wall outer wall is provided with parting coil.
Further, the own body wall thickness minimum at the maximum gauge place on dust cover body wall outer wall.
Further, the cross section of parting coil is circular arc type, and parting coil and dust cover body wall junction seamlessly transit.
Further, parting coil and dust cover body wall are same rubber global formation.
Further, in ball pin seal, be provided with some dustproof profile of tooth circles.
The utility model beneficial effect is obvious: in dust cover main body, establish parting coil, can avoid the cracking of dust cover inwall in the time of sulfidization molding, improve the quality of dust cover, extend the service life of dust cover, improve effect dustproof, anti-muddy water.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral: ball pin seal 1, dust cover body wall 2, ball pin seat seal 3, parting coil 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further, but scope of the present utility model is not limited to following embodiment.
Embodiment 1
A kind of connecting rod dust cover, comprises ball pin seal 1, dust cover body wall 2 and ball pin seat seal 3, and ball pin seat seal 3 outer body walls are provided with fastening mounting groove.
Maximum gauge place on dust cover body wall 2 outer walls is that the minimum place of body wall thickness own is provided with parting coil 4. This is in motion transmitting procedure, and part the most easily produces distortion, facts have proved, there is the product sulfidization molding inwall of die parting line not easy to crack, if do not have the product of die parting line mostly to have stealthy cracking, in use, particularly in long-term fierce motion process, product breakage easy to crack.
The cross section of parting coil 4 is circular arc type, and parting coil 4 seamlessly transits with dust cover body wall junction. Parting coil 4 is same rubber global formation with dust cover body wall 2.
The ball pin seal 1 of dust cover is connected with ball pin, is provided with some dustproof profile of tooth circles in ball pin seal 1. Ball pin seat seal 3 is clamped and is fixed on ball pin seat by clip.
