Abstract
The invention discloses a processing technique for wedge-shaped placket piston rings. In the piston ring prepared by the process, the prior gaps of the piston rings are replaced by wedge-shaped plackets which are 30 degrees so as to form gapless piston rings; in gas charging, compression, doing work and gas discharging of an operational circulation of the engine, with self elastic force, the wedge-shaped placket piston rings can expanding radially during the travels of compression and doing work, and shrink slightly radially during the travels of gas charging and gas discharging, thereby eliminating the downward gas leakage phenomenon occurring during the alignment of gaps of the piston rings circumferentially moving.
Description
Affiliated technical field
The present invention relates to a kind of Wedge type Overlap joint piston ring processing technique, it is applicable to the assembling of all kinds of motors.
Background technique
Compression ring is installed in the top of piston ring zone mainly in order to sealing and heat conduction.Piston ring commonly used has rectangular ring, taper-face ring, twist type ring, bucket face ring, keystone ring and associative ring, and these rings all are compression rings of open type.In use there are two big drawbacks in the open type compression ring: the one, and size gap is difficult to control during assembling; The 2nd, piston ring has circumferential crawl when to-and-fro motion, after piston ring moves to certain hour, the opening of each road ring rests on a certain plain line and no longer wriggles, form collar extension " counterpart " phenomenon of each road ring, cause gas blowby under the motor, Oil Consumption is high especially, and power seriously descends, and motor is short working life.
Summary of the invention
In order to overcome the defective of engine piston ring counterpart, the invention provides a kind of Wedge type Overlap joint piston ring processing technique, with the piston ring of this processes, help engine power to increase, eliminate the phenomenon of gas blowby down, reduce Oil Consumption, prolong motor working life.
The technical solution adopted for the present invention to solve the technical problems is: the opening of former piston ring is changed into wedge shape take mouth, the mouth of taking of piston ring is 30 °, forms the imperforation piston ring.
Beneficial effect of the present invention is: in the work cycle along with engine charge, compression, work done, exhaust, wedge shape is taken gap piston ring and is relied on the elastic force of self, piston ring radial dilatation in compression and expansion space stroke, radially trace contraction of piston ring in air inlet and exhaust stroke, eliminate piston ring " counterpart " gas-blowing phenomenon at present of circumferentially wriggling, guaranteed effective engine power.
Description of drawings
Accompanying drawing is that wedge shape is taken the gap piston ring process flow diagram.
Embodiment
1. technical process for casting and processing mode
Piston ring casting processing: moulding, coating, vanning, batching, melting, casting, drawing, sand removal, heat treatment.
2. process for machining flow process and processing mode
The piston ring machining: boring endoporus, rough turn cylindrical, right boring endoporus, finish turning cylindrical, section, flat stone mill bi-side, finish grind endoporus, finish grind cylindrical, cut the wedge mouth (30 °), chromium plating.
Claims (2)
1. a Wedge type Overlap joint piston ring processing technique with the piston ring of this processes, is changed into wedge shape with the opening of former piston ring and is taken mouth, and the mouth of taking of piston ring is 30 °, forms the imperforation piston ring.
2. Wedge type Overlap joint piston ring processing technique according to claim 1, it is characterized in that: in the work cycle of engine charge, compression, work done, exhaust, wedge shape is taken gap piston ring and is relied on the elastic force of self, piston ring radial dilatation in compression and expansion space stroke, radially trace contraction of piston ring in air inlet and exhaust stroke, eliminate piston ring " counterpart " gas-blowing phenomenon at present of circumferentially wriggling, guaranteed effective engine power.
