Description

Set up the ring mechanism for sealing single piston engine of piston ring

Technical field

The present invention relates to the reciprocating engine piston and subtract ring and improve the core sealing technique, prevent to leak, set up the mechanism of piston ring, the method for standard choosing ring sealing monocycle motor: and be effective method through evidence.

Background technique

Motor innovation piston subtracts ring, studies piston ring is scurried oil from gas leakage between piston and the casing wall physics law: need the gap between packed-piston annular groove outer ring week and the casing wall slip; Closure gasket groove inboard: the radial slot gap of piston ring; Closure gasket groove bottom side: the axial sides gap of ring.

The annular groove inboard: the radial slot gap of ring is as if blow-by, and high-pressure gas is then walked around the ring week outside, enters the ring back clearance along sideshake on the annular groove, lets out the reduction cylinder pressure from forming under the passage between piston and the casing wall through the bottom land compressed gap; Also draw machine oil during low pressure and upwards enter the firing chamber from compressed gap along the loop;

Annular groove bottom side: the axial sides gap of ring: ring is fluctuated, and pump rises on the machine oil and scurries: increase the machine oil exhaust emission.Therefore prevent that piston ring gas leakage from scurrying oil and improving sealing system and create a mechanism.

The mechanism of piston ring: the method for sealing monocycle motor: not only routinely closure gasket groove outer ring week first gap, also answer closure gasket groove inboard radial slot second gap and annular groove bottom side axial sides third space: the present invention: the machine-processed purpose of setting up piston ring is to reform into monocycle piston engine and working machine with encircling reciprocating engine more.

1, press piston ring mechanism standard: choosing ' sealed piston ring ' Fig. 1.Or choosing ' radially ladder cut sealing ring ' Fig. 2.Encircle as bottom side B, seal second compressed gap, and the ring on plus-pressure ring T, eliminate annular groove bottom side sealing third space, form " cut sealing pressure ring " its feature: Fig. 3 together, front elevation seals gap, above-mentioned three place by bottom side radial slot seal ring B and two group rings of upside axial pressure ring T: the air gap between elastic force closure gasket groove outer ring week and the casing wall; The compressed gap of pressurized seal annular groove inner side leakage has channeling oil; Pressure ring bottom land side shaft prevents floatingpump oil to side clearance (or deep processing becomes dish-shaped twist type ring to press to bottom land);

2, the feature of cut sealing pressure ring upside axial pressure ring T: T ring front elevation is simple arch in the monocycle groove, produces axial pressure in groove, and pressure ring B is adjacent to the annular groove bottom side; Prevent to scurry on the compression ring axial float machine oil, pressure is upwards made a concerted effort greater than ring group in the to-and-fro motion, in 400 ℃ of combustion gas of temperature rise, still keeps thermostability work; Vibration, vibration that the pressure adjusting axle encircles when expansion gap and different rotating speeds are rotated, and buffering ring can be filled up B ring outer ring week air gap in addition to unfavorable factors such as the impact force of annular groove end face and noises; T ring processing economic work is reliable; Make by the spring steel ring plate.

3, the feature of cut sealing pressure ring undercut sealed piston ring B in the monocycle groove: outside cylinder: see Fig. 4, otch opens; In cylinder: see Fig. 1, cut closure has otch pressurized seal function increases cylinder pressure, otch sharp angle＜10 °, and the expansion girth of the one section ring that extended is used for the external diameter wearing and tearing and keeps cut closure to prolong pressurized seal greater than the girth of ring external diameter! (sealed piston ring: the patent No.: ZL96119166.X) 4, bottom side B ring relatively: sealed piston ring (Fig. 1) and ladder cut sealing ring (Fig. 2) radially:

Identical point: structures of reform traditional ring all, the adherence to standard gap, to cut closure, pressurized seal pressure increases at cylinder bore, meets machine-processed standard and seals second gap, stops combustion gas to leak from the annular groove inboard; The expansion girth of ring all greater than the girth of ring external diameter, prolongs pressurized seal; The once-through of the whole processing of cluster ring otch, need not that each ring is repaiied mouthful repeatedly, surplus is few, economize with material, technology is new, operation is few, processing is simple and easy, high efficiency!

Difference: the outward appearance difference, Fig. 2 otch does not have acute angle; Greater than the free open gap of tradition ring, the circular arc two ends connect inside and outside radial slot to the footpath circular arc approximately in one section of ring, footpath circular arc ladder right angle incision during formation is radially inside and outside; Higher to Utilization ratio such as the material of tradition ring, technology, frock, anchor clamps.

5, the working principle of cut sealing pressure ring in the monocycle motor: the cut sealing pressure ring is contained among the piston gas ring groove D, Fig. 5, sectional drawing: inner edge 4 overlap joint outsides 5 radial slot closures, the downward pressure ring B of axial pressure ring T is adjacent to the annular groove bottom side, in pumping, join together with piston elasticity, synchronization motion, outer ring week is walked around in combustion gas above the annular groove, along dotted line: do not have the passage of leaking from entering ring back clearance to bottom land on the T ring between the side wave seam, act on otch inner edge 4 and be adjacent to outside 5, strengthen pressurized seal and increase cylinder pressure; Machine oil under the annular groove is along solid line: because of the ring end, compressed by the T ring, and the undirected pump oil free gap of going up, machine oil is scurried on not: at ring end outside cloth oil, lubricated, cooling improves working conditions, and reduces the machine oil exhaust emission from spill port C return piston inner chamber; Cut sealing pressure ring cloth oil frizing parting seal: Fig. 6 downwards that makes progress in combustion gas and the machine oil coverlet annular groove, the short-and-medium type piston of monocycle groove motor: deducted unnecessary annular groove and ring bank height, only there be one compression D to be reduced to the minimum oil ring groove of piston tradition position, it on the groove top bank, no drainback passage in the groove, there is spill port C in the bottom land outside;

6, cut sealing ring B and traditional chain rate:

Resemblance: all have right angle incision, Dou otch and stepped shaft otch etc. and be applied to various model motors; Difference: the neither closure of radial slot of tradition ring, can not seal second gap, existing prevents to leak gas scurries oily technical bottleneck, needs the compression ring oiling ring encircle sealing more, is difficult to subtract the environment-development exhibition only through multiple improvement; Cut sealing ring B, the radial slot closure has the pressurized seal function, presses piston ring mechanism and forms the cut sealing pressure ring, seals gap, three places, and the monocycle engine cylinder pressure increases, and promotes reciprocating engine and subtracts the environment-development exhibition.

7, by the characteristics of piston ring mechanism cut sealing pressure ring sealing monocycle motor: cancellation oil ring machine oil is scurried on not; Reducing the compression ring cylinder pressure increases, and solves many ring engines, subtracts ring, leaks gas, scurries oil, is difficult to subtract cut sealing technical barriers such as ring; If engine piston subtracts into monocycle by the Fourth Ring, deduct three rings and account for 75% friction power loss and wearing and tearing, raising mechanical efficiency, life-saving; Comprehensive compact structure, the quality that alleviates, raising rotating speed increase power; Saving complete machine resource, the energy, reduction engine oil consumption reduce pollution emissions!
