Description
Technical field
This utility model belongs to technical field of bearings, specifically, more particularly to a kind of new deep groove ball bearing contact
Sealing structure.
Background technology
Deep groove ball bearing is a most universal type in rolling bearing, and the deep groove ball bearing of basic model is outer by one
Circle, an inner ring, one group of steel ball and one group of retainer are constituted, and which is divided into sealing and two kinds of structures of open type, and open type refers to bearing not
Band sealing structure, closed type deep-groove ball are divided into contact and non-contacting seal.But contact seal depth of the prior art
In use for some time, its dust-proof effect can decline ditch ball bearing, especially in the relatively large number of work of dust, silt and rainwater
Environment, sealing can not effectively be resisted and make it into Bearing inner so that premature wear or damage easily occurs in deep groove ball bearing
It is bad, increased the cost for using.
Utility model content
In view of the above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to provide a kind of new
Deep groove ball bearing contact type sealing structure.
The technical solution of the utility model is as follows：A kind of new deep groove ball bearing contact type sealing structure, outer ring with it is interior
Rolling element is installed between circle, the both sides of the rolling element are provided with sealing ring, and sealing ring is also flush-mounted between outer ring and inner ring, institute
The inner edge for stating sealing ring is formed with vertical lip, in the seal groove on the embedded interior ring outer wall of the vertical lip, and vertical lip
Mouthful with the bottom land interference fit of seal groove, it is characterised in that：Towards a bodily form on the end face of rolling element in the middle part of the sealing ring
Into there is horizontal lip, the horizontal lip near vertical lip, horizontal lip and the one of medial wall interference fit of seal groove, and
Laterally relief groove is formed between lip and vertical lip.
Using above technical scheme, increase a horizontal lip on sealing ring, the horizontal lip is with inner ring seal groove side
Face interference fit；A relief groove is formed between horizontal, vertical lip, it is therefore an objective to disperse sealing ring internal pressure, reduce contact and rub
Wipe torque.With inner ring seal groove bottom interference fit, at two, interference fit compares interference at conventional to vertical lip, can disperse suffered
Frictional force, reduces contact area, reaches the effect for reducing ring wear.Due to the oil storage of relief groove energy and contact of formation
Lip is resisted against inner ring, makes dust-proof and sealing effectiveness more preferable.
Preferably, " V " shape of the relief groove for circular arc bottom, the angle between horizontal lip and vertical lip is 72-
78°。
Beneficial effect：This utility model simple structure, it is good to have dust-proof, the grease-proof performance that leaks concurrently, and seal wear-resistant
Property it is good, transformation easily, improvement cost it is low, be suitable on various types of deep groove ball bearings.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Structural representations of the Fig. 2 for sealing ring.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1 and Figure 2, this utility model is made up of outer ring 1, inner ring 2, rolling element 3 and sealing ring 4 etc..Wherein, exist
Rolling element 3 is installed between outer ring 1 and inner ring 2, the both sides of the rolling element 3 are provided with sealing ring 4, and sealing ring 4 is also flush-mounted in outer
Between circle 1 and inner ring 2.Vertical lip 41 is formed with the inner edge of sealing ring 4, the vertical lip 41 is embedded in 2 outer wall of inner ring
On seal groove 21 in, and the bottom land interference fit of vertical lip 41 and seal groove 21.Towards rolling element 3 in the middle part of sealing ring 4
End face on be formed with horizontal lip 42, the horizontal lip 42 near vertical lip 41, horizontal lip 42 and seal groove 21
One of medial wall interference fit, and laterally relief groove 43 is formed between lip 42 and vertical lip 41.Relief groove 43 is preferred
For the " V " shape of circular arc bottom, the angle between horizontal lip 42 and vertical lip (41) is 72-78 °.
The structure that this utility model is not described is same as the prior art, will not be described here.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations according to design of the present utility model without the need for creative work.Therefore, all this technology necks
In domain, technical staff passes through logical analyses, reasoning or limited reality on the basis of existing technology according to design of the present utility model
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
