Abstract
The utility model belongs to the technical field of bearing fittings and specifically relates to a double-lip adhesive bearing dust shield. The double-lip adhesive bearing dust shield comprises a ring skeleton and is characterized in that: at outer edge of an inner end face of the skeleton has an inward protrusion; an inner edge of an inner end face has an outward recessed portion in which a ring rubber ring is arranged closely; and an inner wall of the rubber ring extends radially and has two rings of seal lips. The double-lip adhesive bearing dust shield is featured with simple processing, easy molding, high intensity, and excellent sealing effect; moreover, the inner wall of the rubber ring extends radially and has the two rings of seal lips, so that the outside seal lip is used for preventing outside contaminants from entering a bearing, thereby preventing the bearing from damage; and the inside seal lip is used for preventing grease in the bearing from overflow. By using the double-lip adhesive bearing dust shield, the grease of the bearing is not easy to leak, and outside impurities and dust are difficult to enter the inside, thereby greatly improving the service life of the bearing.
Description
Technical field
The utility model belongs to the Bearing fittings technical field, is specifically related to a kind of lips band glue bearing dustproof cover.
Background technique
Dust cover is the critical component that bearing runs well in rugged environment, and it plays the protection bearing and avoids erosion and pollution, and bearing can be worked in the lubricated environment of good cleaning.And the inside of bearing is owing to need a large amount of grease lubrications, if sealing effect is bad, it is excessive to produce grease, influences the running of bearing.There are following shortcoming in dust cover and seal ring commonly used: it is better that 1, dust cover assembles back intensity on bearing, but sealing effect is not good; 2, assembling back sealing effect is better on bearing, but intensity is not good.
The model utility content
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of lips band glue bearing dustproof cover of processing simple, good seal performance, long service life is provided.
Described lips band glue bearing dustproof cover, comprise the skeleton that is circular, the interior edge face outer rim that it is characterized in that described skeleton has inside lug boss, the interior edge face inner edge has outside reentrant part, the drive fit socket is provided with circular rubber ring in the female portion, the inwall of described rubber ring radially extend be provided with two the circle sealing lips.
Described lips band glue bearing dustproof cover is characterized in that the female portion is equipped with terraced steps, and rubber ring tightly fits in above-mentioned terraced steps.
Described lips band glue bearing dustproof cover is characterized in that described two circle sealing lips are in the outside that axially is in above-mentioned lug boss.
Described lips band glue bearing dustproof cover, it is characterized in that described sealing lip inner edge arranged outside breach, the rectangular shape of described breach.
Described lips band glue bearing dustproof cover is characterized in that the outer wall of described lug boss is outer little interior big toroidal surface structure.
Lips band glue bearing dustproof cover provided by the utility model compared with prior art, has following advantage:
1, processing is simple, and formed product is easy, and by the structural design of skeleton dust cover and inwall rubber seal thereof, it is good to make it have intensity simultaneously, the advantage that sealing effect is good;
2, described rubber ring inwall cooperates extension to be provided with two circle sealing lips, the sealing lip in the outside is used to stop environmental contaminants to enter bearing, prevent to damage bearing, inboard sealing lip is used to stop the grease in the bearing excessive, and the multi-ring annular seal groove can increase sealability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross section of the present utility model enlarged diagram;
Fig. 3 is applied to the structural representation of bearing for the utility model;
Fig. 4-Figure 11 is the structural representation of the other several mode of executions of the utility model;
Among the figure, 1, skeleton; 1a, reentrant part; 1b, lug boss; 1c, outer wall; 2, rubber ring; 2a, sealing lip; 2b, breach; 3, bearing; 3a, bearing outer ring; 3b, bearing inner race.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description:
As shown in Figure 1 and Figure 2, these lips band glue bearing dustproof cover, comprise the skeleton 1 that is circular, the interior edge face outer rim of described skeleton 1 has inside lug boss 1b, the interior edge face inner edge has outside reentrant part 1a, the drive fit socket is provided with circular rubber ring 2 in the 1a of the female portion, and the inwall of described rubber ring 2 radially extends and is provided with two circle sealing lip 2a.The outer wall 1c of described lug boss 1b is outer little interior big toroidal surface structure, and as Fig. 3, this lug boss 1b rabbets in the annular groove of bearing outer ring 3a, connects fastening.
As Fig. 2, in the present embodiment, reentrant part 1a is equipped with terraced steps, and the sidewall interference fit of the outer wall of rubber ring 2 and terraced steps is combined closely in skeleton 1 rubber ring 2.As Fig. 2, Fig. 3, in the present embodiment, the reentrant part 1a degree of depth is darker, and two circle sealing lip 2a enlarge bearing 3 inner spaces in the outside that axially is in above-mentioned lug boss 1b, and sealed circuit is longer, has prevented the leakage of grease effectively.
As Fig. 2, for making sealing lip 2a inner edge and bearing inner race 3b better realize interference fit, in the present embodiment, the outside at sealing lip 2a inner edge has been equipped with breach 2b, the rectangular shape of described breach 2b, make the attenuation of sealing lip 2a inner edge, can closely contact, to realize better sealing effect with bearing inner race 3b.
In addition, the utility model is not limited in the foregoing description, according to this design, because skeleton 1, the shape of rubber ring 2 and the difference of combination thereof also can produce various embodiments, is exactly the other several mode of executions of the utility model as Fig. 4-Figure 11.
The utility model processing is simple, moulding is easy, structural design by skeleton dust cover and inwall rubber seal thereof, it is good to make it have intensity simultaneously, the advantage that sealing effect is good, and described rubber ring inwall cooperates extension to be provided with two circle sealing lips, the sealing lip in the outside is used to stop environmental contaminants to enter bearing, prevent to damage bearing, inboard sealing lip is used to stop the grease in the bearing excessive, and the multi-ring annular seal groove can increase sealability.
Because bearing in use will be invaded through high-loaded, extremely strong impact force and water and rust bits, very easily damages.And application the utility model makes the grease of bearing be difficult for revealing, and outside foreign material and dust are difficult to invade inner, the working life of having improved bearing greatly.
