Abstract
The utility model relates to a sealed type piston ring which is composed of a circular ring body (2) and an opening (3). A ring body opening (4) is arranged at the opening (3), and the opening (3) is larger than the ring body opening (4). Gap connecting positions are arranged between the ring body opening (4) and the opening (3) of the circular ring body (2). All the gap connecting positions have the same orientation, and a plurality of piston ring grooves (5) are arranged on the ring body (2) disposed on two sides of the ring body opening (4). Compared with a traditional piston ring, the sealed type piston ring is provided with the plurality of piston ring grooves on the ring body, and the piston ring grooves can effectively seal the piston ring and a piston when the piston ring is connected with the piston so as to achieve gas sealing of the whole circulation and sealing ports in a slide block mode. Tension everywhere is balanced, sealing effect is improved, and service life of the piston ring is prolonged. The sealed type piston ring is simple in structure, easy to produce and machine, and quite convenient to use.
Description
Technical field
The utility model relates to a kind of piston ring, especially a kind of closed type piston ring.
Background technique
In the power system field, in the mechanical device such as motor, driver and a lot of piston type motions, mostly adopt the structure of cylinder, piston to carry out power output.Have the place of piston generally all to be provided with piston ring, piston ring also is widely used in the various mechanical devices such as petrol engine, diesel engine, engineering machinery, internal-combustion engine, air pump, water pump.The effect of piston ring mainly is the sealing that keeps between piston and the cylinder, and the assurance power system is reduced the loss when fuel is converted to mechanical energy as far as possible.Simultaneously, piston ring can be organized the bump between piston and the cylinder effectively.Because piston ring often rubs, the operating conditions very severe must keep seal operation under condition of high voltage, relative sliding friction velocity that also will be between sliding friction speed and high temperature lower piston ring and cylinder wall is very high, surpass 10 meter per seconds, operating temperature can reach about the 300-400 degree.Therefore the quality of piston ring has determined working stability, reliability and the useful life longevity of motor.
The pressure that brings in order to reduce friction, general, piston ring all is installed in the piston ring groove, in order to reduce friction, pours into lubricant oil between piston ring and the outer cover, but this mode can not tackle the problem at its root.Therefore people have focused on attention quality and the abrasion resistance aspect that how to improve piston ring, there is plating Chrome add strong hardness in the prior art, but practical operation is found, because hardness is strengthened, not easy to wear, affect initial fitting property and self lubricity, needed long-term break-in just can reach suitable state, increased oil consumption.
The model utility content
In order to overcome the deficiencies in the prior art, resolve the problem of prior art, remedy the existing in the market deficiency of existing product.
The utility model provides a kind of closed type piston ring, piston ring is made of circular ring body and opening, opening is provided with the ring body opening, opening is greater than the ring body opening, be provided with seam crossing between the opening of ring body opening and ring body, all seam crossings towards unanimously, the ring body on ring body opening both sides is provided with a plurality of piston ring grooves.
Preferably, above-mentioned ring body is made with resilient sheet metal.
Preferably, above-mentioned ring body is made with stalloy or alloy-steel sheet.
Preferably, above-mentioned piston ring and piston body support the use.
Preferably, above-mentioned piston body is cylindrical body, in be provided with hub in the rigidity, at the upper end of the piston body outer surface circular groove that caved inward.
Preferably, above-mentioned piston ring groove is one-body molded on piston ring.
The closed type piston ring that the utility model provides is compared with traditional piston ring, the closed type piston ring that the utility model provides is provided with a plurality of piston ring grooves at ring body, piston ring groove can realized sealing effectively when piston ring is connected with piston, realized the envelope gas of whole circulation, the sealed interface of slide block type, balanced tension force has everywhere improved the effect of sealing, has also prolonged the working life of piston ring.The utility model simplicity of design is easy to production and processing, uses also very convenient.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses schematic representation.
Mark among the figure: 1-piston ring; The 2-ring body; The 3-opening; 4-ring body opening; The 5-piston ring groove; The 6-piston body; Hub in the 7-; The 8-circular groove.
Embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Be illustrated in figure 1 as closed type piston ring structure generalized section of the present utility model, consisted of by circular ring body 2 and opening 3 on the main body on the main body, opening 3 places are provided with ring body opening 4, opening 3 is greater than ring body opening 4, be provided with seam crossing between the opening 3 of ring body opening 4 and ring body 2, all seam crossings towards unanimously, the resilient sheet metal of ring body 2 usefulness is made.Preferably, ring body 2 usefulness stalloys or alloy-steel sheet are made.
Inventive point of the present utility model and innovative point are: the ring body 2 on ring body opening 4 both sides is provided with a plurality of piston ring grooves 5.Piston ring groove 5 is one-body molded on piston ring 1.
The closed type piston ring that the utility model provides is compared with traditional piston ring, the closed type piston ring that the utility model provides is provided with a plurality of piston ring grooves at ring body, piston ring groove can realized sealing effectively when piston ring is connected with piston, realized the envelope gas of whole circulation, the sealed interface of slide block type, balanced tension force has everywhere improved the effect of sealing, has also prolonged the working life of piston ring.The utility model simplicity of design is easy to production and processing, uses also very convenient.
The embodiment of the above is preferred embodiments of the present utility model; be not to limit implementation scope of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment that the equivalence that all shapes according to the utility model, structure are done changes all in protection domain of the present utility model.
