Abstract
The utility model relates to a bearing fittings technical field, concretely to a three-lip rubber bearing dust cap, which comprises a circular ring shaped frame characterized in that an inward convex portion is arranged on an outer edge of an inner end surface of the frame; an outward concave portion is arranged on an inner edge of an inner end surface; the circular ring shaped rubber ring is tightly-fittably sheathed in the concave portion; and three circles of sealing lips are formed through radial extension of the inner wall of the rubber ring. The utility model has advantages of simple processing, easy forming, high strength and good sealing effect; and three circles of sealing lips are formed through radial extension of the inner wall of the rubber ring; sealing lips on the outer side are used for preventing extraneous pollutants from entering into the bearing and avoiding damage of the bearing; sealing lips on the inner side are used for preventing oil in the bearing from overflowing; thereby the oil of the bearing is not easy to leak; and extraneous pollutants and dusts are difficult to intrude to inside so as to greatly prolong 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 three lip band glue bearing dustproof covers.
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 three lip band glue bearing dustproof covers of processing simple, good seal performance, long service life are provided.
Described three lip band glue bearing dustproof covers, 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 three the circle sealing lips.
Described three lip band glue bearing dustproof covers is characterized in that the female portion is equipped with terraced steps, and rubber ring tightly fits in above-mentioned terraced steps.
Described three lip band glue bearing dustproof covers is characterized in that described three circle sealing lips are in the outside that axially is in above-mentioned lug boss.
Described three lip band glue bearing dustproof covers, it is characterized in that described sealing lip inner edge arranged outside breach.
Described three lip band glue bearing dustproof covers is characterized in that the outer wall of described lug boss is outer little interior big toroidal surface structure.
Three lip band glue bearing dustproof covers provided by the utility model compared with prior art, have 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 three 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 constituted the multi-ring annular seal groove, make sealed circuit long and tortuous, increase sealing effect greatly.
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 10 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; 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 three lip band glue bearing dustproof covers, 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 three 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 three 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.Sealing lip 2a is thinner, with bearing inner race 3b interference fit, it can closely be contacted, 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 10.
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 three 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 constituted the multi-ring annular seal groove, and make sealed circuit long and tortuous, increased sealing effect greatly.
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.
