Leaf spring can compensate for the gap generated due to abrasion, it is excessive guarantee that the grease in bearing is not easy, the end of rib is coated with
Sealant can prevent dust from entering in bearing from bearing outside, improve the service life of bearing.
To achieve the above object, the utility model proposes a kind of four lip seal anti-dust seals, including support frame, sealing
Part, leaf spring and the cover, the support frame are circular ring shape, and the outer diameter of the support frame is equipped with rib, and the rib hangs down
Directly in support frame, the internal diameter of the support frame is equipped with sealing element, and the sealing element is close equipped with the first sealing and second
Envelope portion is equipped with leaf spring in the cavity between first sealing and the second sealing, and the outer diameter of the cover is equipped with
Back-shaped flanging, first sealing are equipped with the first sealing lip, and first sealing lip is matched with the inner ring of back-shaped flanging,
The side wall of second sealing is equipped with the second sealing lip, and the side wall of second sealing lip and the cover is fitted close, and described the
The inner ring of two sealing lips is equipped with secondary lip, and the internal diameter of second sealing is equipped with third sealing lip.
Preferably, the cross sectional shape of the back-shaped flanging is U-shaped, the internal diameter of the cover is equipped with the second flanging, institute
The outer wall that the second flanging is stated perpendicular to the cover, the third sealing lip and secondary lip and the second flanging is fitted close.
Preferably, the cross sectional shape of the leaf spring is V-shaped, the Liang Ge branch of the leaf spring clamps respectively
On the first sealing lip, the second sealing lip.
Preferably, the outer diameter of the sealing element is extended with sealant, the sealant is coated on the right side of rib,
The sealant is matched with bearing outside.
The utility model has the beneficial effects that the utility model passes through support frame, sealing element, leaf spring and the cover etc.
Cooperation, the lateral skirt of two of them and the cover are in close contact, and lateral lip is long and thin to have good elastic deformation performance, can
Close sealing space is formed, while the gap due to sealing part abrasion generation, leaf spring can compensate for using leaf spring
It drives the first sealing lip, the second sealing lip, secondary lip and the cover to keep close-fitting state, it is outer to guarantee that the grease in bearing is not easy
It overflows, the end of rib is coated with sealant, can prevent dust from entering in bearing from bearing outside, and that improves bearing uses the longevity
Life.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
