Description
Technical field
The utility model is related to the technical field of seal ring structure, especially a kind of wear-resistant seal ring.
Background technology
Oil cylinder is the most commonly seen part of hydraulic drive, and oil cylinder includes cylinder barrel 9, piston rod 10 and piston 11, the piston
Bar is threadedly coupled with piston 11, and the outside of piston 11 is equipped with sealing ring 12, and sealing ring 12 is bonded such as Fig. 1 with the inner wall of cylinder barrel 9
Shown, piston rod 10 pushes piston 11 in cylinder barrel 9 in moving process, sealing ring 12 can prevent the hydraulic oil in cylinder barrel 9 by
Dynamic sealing is formed in one chamber leaks to another chamber.Therefore sealing ring is the important composition component of cylinder seal.However,
With the reciprocating friction of sealing ring 12 and cylinder barrel 9, sealing ring 12 will be caused to wear, sealing ring 12 increases with 9 gap of cylinder barrel, cylinder barrel
Hydraulic oil in 9 is revealed from the gap, and there are poorly sealed close defects, and is frequently replaced sealing ring 12 and also bothered very much,
Increase the maintenance cost of worker.Therefore there is an urgent need for a kind of sealing rings for capableing of automatic compensation gap.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, service life is long, nothing
Worker is needed frequently to replace sealing ring, mitigate worker's maintenance cost, replacement or safeguard efficiently wear-resistant seal ring.
The purpose of this utility model is achieved through the following technical solutions：A kind of wear-resistant seal ring, it include piston shaft and
Sealing ring, the piston shaft are made of push rod connected in sequence, prism and position-arresting disk, are offered on each faceted pebble of the prism
The outside of blind hole, prism is cased with sealing ring, and the outer diameter of sealing ring is more than the outer diameter of position-arresting disk, multiple superpositions are provided in blind hole
Flat spring, flat spring press between blind via bottom and sealing ring inner wall, and external screw thread, push rod are offered on the cylinder of the push rod
On be provided with thread bush, offer internal thread in thread bush, the internal thread of thread bush and the external screw thread of push rod connect, the sealing
Circle presses between thread bush and position-arresting disk.
The outer diameter of the thread bush is equal with the outer diameter of position-arresting disk.
The prism is quadrangular.
The push rod, prism and position-arresting disk coaxial arrangement.
The sealing ring is coaxially disposed with prism.
The utility model has the following advantages：The utility model is compact-sized, service life is long, is frequently replaced without worker
Sealing ring mitigates worker's maintenance cost, replacement or safeguards quick.

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Fig. 2 ~ 3, a kind of wear-resistant seal ring, it includes piston shaft and sealing ring 1, and the piston shaft is by being sequentially connected with
Push rod 2, prism 3 and position-arresting disk 4 form, push rod 2, prism 3 and position-arresting disk 4 are coaxially disposed, on each faceted pebble of the prism 3
Blind hole 5 is offered, the outside of prism 3 is cased with sealing ring 1, and sealing ring 1 is coaxially disposed with prism 3, and the outer diameter of sealing ring 1 is more than limit
The outer diameter of position disk 4, is provided with the flat spring 6 of multiple superpositions in blind hole 5, flat spring 6 press on 5 bottom of blind hole in sealing ring 1
Between wall, external screw thread 7 is offered on the cylinder of the push rod 2, thread bush 8 is provided on push rod 2, is offered in thread bush 8 interior
The internal thread of screw thread, thread bush 8 is connect with the external screw thread of push rod 2, the sealing ring 1 press on thread bush 8 and position-arresting disk 4 it
Between, i.e. thread bush 8 and position-arresting disk 4 in the axial direction fixes sealing ring 1.
As shown in Fig. 2 ~ 3, the outer diameter of thread bush 8 described in the present embodiment is equal with the outer diameter of position-arresting disk 4.The prism 3
For quadrangular.
The course of work of the utility model is as follows：In use, the sealing ring is filled in the cylinder barrel 9 of oil cylinder, make sealing ring 1
It is fitted close with cylinder barrel 9 as shown in figure 4, pushing push rod 2 to the left, position-arresting disk 4 compresses the hydraulic oil in cylinder barrel 9, and sealing ring 1 is anti-
Only hydraulic fluid leak.With the working long hours back and forth of piston rod 10, the surface wear of sealing ring 1,1 outer diameter of sealing ring is gradual
Become smaller, sealing ring 1 generates gap with cylinder barrel 9, and 1 radial deformation of lower seal, i.e. deformation side are acted in 6 spring restoring force of flat spring
, to fill gap, to realize automatic compensation, hydraulic oil leakage is avoided to towards the gap generated, it is ensured that sealing ring 1 makes
With more persistently, sealing ring is frequently replaced without worker, is had the characteristics that with long service life.When replacing or safeguard sealing ring
When, need to only unscrew set 8, and thread bush 8 is unloaded from push rod 2, then sealing ring 1 moves right along the axis of push rod 2
Go out, facilitate the quick-replaceable sealing ring of worker, improves working efficiency.
