Description

Piston ring of breaking hammer

Technical Field

The utility model belongs to the machining field relates to a quartering hammer piston ring.

Background

The hydraulic breaking hammer is an important engineering machine which uses hydraulic energy as power to drive a piston positioned in an upper cylinder body of a hydraulic cylinder to do reciprocating motion, a drill rod is hammered by the piston to transmit energy to the drill rod, and the energy on the drill rod is absorbed by a struck object, so that the struck object is broken, the hydraulic breaking hammer is mainly used for the work of breaking, dismantling, hard layer excavation and the like in building construction, is usually installed on an excavator, a loader or a power station, and has the advantages of large impact force, convenience in use, good maneuverability, high efficiency and the like.

Hydraulic breaking hammer mainly installs and is used for carrying out the crushing operation to the stone on mechanical device, and its theory of operation is comparatively simple, mainly drives the drill rod through the reciprocating cycle of piston and stretches out and draws back, lets the tip of drill rod hit the stone and carries out the crushing operation, and current breaking hammer piston ring simple structure leads to the breaking hammer during operation time easily, and the piston rod produces the skew and the not good enough problem of piston ring sealing performance.

Disclosure of Invention

The utility model aims at providing a stable in structure, reasonable in design and better quartering hammer piston ring of sealing performance to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a quartering hammer piston ring, includes the piston ring main part, its characterized in that, piston ring main part inner wall on be provided with the simple structure and the good seal structure of simple sealing performance, seal structure from left to right constitute by gas seal groove, oil return groove, guide way, main oil blanket groove and stet seal groove in proper order, gas seal groove, oil return seal groove, main oil blanket groove and stet seal groove all set up the sealing member that plays sealed effect, guide way and main oil blanket groove between be provided with and inlay the copper snap ring on the piston ring inner wall, the guide way in install the guidance tape that has the guide effect.

In foretell quartering hammer piston ring, the atmoseal inslot set up the atmoseal circle that has sealing effect, the oil return seal inslot set up the oil return that has sealing effect and seal, main oil seal inslot set up the main oil blanket that has sealing effect, steve inslot set up the steve oil blanket that has sealing effect.

In the piston ring of the breaking hammer, a groove for embedding the copper clamp ring in the inner wall of the piston ring is formed between the guide groove and the main oil seal groove.

In foretell quartering hammer piston ring, the guide way internal diameter be less than gas seal groove, oil return seal groove, stet seal groove and main oil seal groove, main oil seal groove internal diameter be less than gas seal groove, oil return seal groove and stet seal groove, the internal diameter of gas seal groove, oil return seal groove and stet seal groove equals.

Compared with the prior art, the piston ring of the breaking hammer has the advantages of simple structure, reasonable design and multiple sealing structures, so that the piston ring has better sealing performance.
