Abstract
The utility model discloses a kind of accurate sealing glands comprising：Outer circle, endoporus and annular groove；Endoporus is opened up at the center of the outer circle；An annular groove is respectively provided at the outer circle and endoporus, and the position of two annular grooves is corresponding；It is both provided with sealing ring in two annular groove.The present apparatus increases the stability of movement and the service life of part during use, also effectively prevents oil leak.
Description
Technical field
The utility model is related to mechanical exquisite system fields, more particularly to a kind of accurate sealing gland.
Background technology
Since fit clearance is excessive in mechanical structure motion process, it is poor to be easy to cause kinetic stability, and is using
It will produce oil leakage phenomenon in the process, lead to part reduced service life.Gap usually between end cap and bearing block is built-in
Enter sealing ring and compresses, to ensure that bearing block is oil-proof, but this method sealing ring can influence each other with gap, it is difficult to ensure that its
Sealing effect, working efficiency are low.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of accurate sealing gland, reasonable design, structure
Simply, the problem of solving in the prior art that sealing gland stability is poor, and being easy to cause oil leak and shorten part service life.
In order to solve the above technical problems, the technical solution that the utility model uses is to provide a kind of accurate sealing pressure
Lid comprising：Outer circle, endoporus and annular groove；Endoporus is opened up at the center of the outer circle；It is respectively provided at the outer circle and endoporus
One annular groove, and the position of two annular grooves is corresponding；It is both provided with sealing ring in two annular groove.
Preferably, further include seal suction disc；Ring packing sucker is set in the outer circle of the bottom edge of the endoporus；
Preferably, a diameter of 69mm of the outer circle, a diameter of 50mm of the endoporus；
Preferably, the tolerance of the outer circle is Φ 69-0.015mm, and the tolerance of endoporus is Φ 50+0.012mm；
Preferably, the outer circle is made of stainless steel material；
Preferably, the sealing ring is made of rubber material.
The utility model has the beneficial effects that：The utility model is simple in structure, reasonable design, by being set in annular groove
It sets sealing ring and is effectively increased gland and the stability between pipe fitting, and effectively prevent mechanical oil leak, increase
The service life of part.
Description of the drawings
Fig. 1 is a kind of sectional view of accurate sealing gland of the utility model；
Fig. 2 is a kind of vertical view of accurate sealing gland of the utility model；
The label of each component is as follows in attached drawing：1, outer circle；2, endoporus；3, annular groove；4, seal suction disc.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
Attached Fig. 1 and 2 is please referred to, the utility model embodiment includes：Outer circle 1, endoporus 2 and annular groove 3；The outer circle 1 by
Stainless steel material is made, and prevents outer circle 1 from corroding.Endoporus 2 is opened up at the center of the outer circle 1；It is socketed in docking zero by endoporus 2
On part.An annular groove 3 is respectively provided at the outer circle 1 and endoporus 2, and the position of two annular grooves 3 is corresponding；In two annular
Sealing ring is both provided in slot 3, and sealing ring is made of rubber material；It is effectively hindered by the way that sealing ring is arranged in annular groove 3
The phenomenon that having stopped oil leak in use, and increase the stability of movement.In the outer circle of the bottom edge of the endoporus 2
Ring packing sucker 4 is set on 1；The generation of oil leakage phenomenon is further prevented by seal suction disc 4.
Preferably, a diameter of 69mm of the outer circle 1, a diameter of 50mm of the endoporus 2, and the tolerance of outer circle 1 is
The tolerance of Φ 69-0.015mm, endoporus 2 are Φ 50+0.012mm.Being more advantageous to prevents oil leak during use, increases
The stability of movement, and increase the service life of part.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is equally included in the patent within the scope of the utility model.
