Description
Technical field
The utility model relates to sealing element technical fields, and in particular to a kind of Z-type dustband.
Background technique
Bearing belongs to vulnerable part in whole equipment, guarantees that the good operation of bearing ensures that the normal fortune of whole equipment
Turn, thus the seal protection measure of bearing block just play the role of it is vital.In the practical work process of equipment, dust
Harm be it is very serious, once dust, which enters bearing block, influences bearing, bearing, can in play after it cannot get good lubrication
It is burnt during strong dry friction, equipment will also shut down, and will lead to the chain rupture of production link, cause serious economic damage
It loses.
Utility model content
The utility model provides a kind of Z-type dustband, to solve the problems, such as that bearing is dust-proof, seals.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of Z-type dustband, including section is in
Trapezoidal main body, be arranged in trapezoidal shaped body upper bottom side the first sealing lip and lower bottom side that trapezoidal shaped body is set it is second close
Lip is sealed, first sealing lip connects with the side waist of the main body and connects to forming the first acute angle with the upper bottom of the main body,
Second sealing lip connects with the other side waist of the main body and connects to forming the second acute angle with the bottom of the main body.
Further, the two sides waist of the trapezoidal shaped body is close to the two side walls of the groove respectively.
Further, the two sides kidney-shaped of the main body at angle be 14~15 °.
Further, first acute angle is 35~45 °.
Further, second acute angle is 35~45 °.
Further, the upper bottom joint of first sealing lip and the main body is equipped with fillet.
Further, the bottom joint of second sealing lip and the main body is equipped with fillet.
The beneficial effects of the utility model are: structure is simple, installation space is small, and dustband passes through with bearing groove, axis
Face contact realizes two way seal, dust-proof, sealing effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one specific embodiment of Z-type dustband described in the utility model；
Fig. 2 is the scheme of installation of Z-type dustband described in the utility model.
As shown in the figure: 100-Z type dustband, 110- main body, the first side 111- waist, 112- second side waist, 120- first are close
Seal lip, the second sealing lip of 130-, α-the first acute angle, β-the second acute angle, γ-angle, 200- rolling bearing, 210- groove, 300-
Axis.
Specific embodiment
In order to make it easy to understand, illustrating the technical characteristics of the utility model below with reference to embodiment.It should be understood that these embodiments
It is merely to illustrate the utility model rather than limitation the scope of the utility model.
As shown in Figs. 1-2, Z-type dustband 100 described in the utility model, for the dust-proof of rolling bearing 200 and sealing, peace
In groove 210.The Z-type dustband 100 includes the trapezoidal main body 110 in section, the upper bottom that trapezoidal shaped body 110 is arranged in
Second sealing lip 130 of the first sealing lip 120 and the lower bottom side that trapezoidal shaped body 110 is set of side.First sealing lip 120
Connect with the first side waist 111 of the main body 110, and the shape that connects with the upper bottom of the main body 110 is angled the of 35~45 °
One sharp angle α；Second sealing lip 130 connects with second side waist 112 of the main body 110, and connects with the bottom of main body 110
Shape is angled 35~45 ° of the second acute angles beta；That is, main body 110 and the first sealing lip 120,130 phase of the second sealing lip
It connects to form a Z-type.Angle γ between the first side waist 111 and second side waist 112 of trapezoidal shaped body 110 is 14~15 °, and the
Side waist 111 and second side waist 112 are close to the two side walls of the groove 210 respectively.
Further, to avoid the Z-type dustband 100 from being easy to appear crackle when being interference fitted with groove 210, first is close
The upper bottom joint for sealing lip 120 and main body 110 is equipped with fillet, and the second sealing lip 130 and the bottom joint of main body 110 are equipped with circle
Angle.Preferably, the thickness of the main body 110, i.e., trapezoidal height are 1.5~2 times of the thickness of sealing lip, it is ensured that main body 110
To the support strength of two sealing lips.
Emphasis is referring to shown in Fig. 2, and the working principle of Z-type dustband 100 described in the utility model is as follows: Z-type dustband 100
It is mounted in the groove 210 of rolling bearing 200, is interference fitted with groove 210.First side waist 111 and second of trapezoidal shaped body 110
Side waist 112 is interference fitted with the two side walls of groove 210 respectively, and the bottom of the first sealing lip 120 and groove 210 is interference fitted,
Second sealing lip 130 is interference fitted with axis 300.It is all face contact at cooperation between above-mentioned each component, realizes Z-type dustband
The two way seal effect of 100 pairs of rolling bearings 200, i.e. Z-type dustband 100 can both prevent external dust and dirty pass through rolling
Bearing 200 enters inside sealing system, and prevented also from the lubricating oil in sealing system to outward leakage, sealing effect is reliable and stable.
Meanwhile 100 structure of Z-type dustband described in the utility model is simple, compact, installation space is small.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations.
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It can still modify to technical solution documented by previous embodiment, or to some or all of the technical features
It is equivalently replaced, and these modifications or substitutions, various embodiments of the utility model that it does not separate the essence of the corresponding technical solution
The range of technical solution.
