Description

The rotor arrangement of rotary polygonal piston engine

Technical field

The utility model relates to a kind of rotor arrangement of rotary polygonal piston engine.

Background technique

General motor is the reciprocating motion type motor, and piston is done linear reciprocating motion during work in cylinder, rotatablely moves for the straight line motion of piston is converted into, and must use connecting rod.Rotary engine is then different, and it directly is converted into driving torque with the burning expansion power of combustible gas.Compare with Reciprocating engine, rotary engine has been cancelled useless straight line motion, thereby the rotary engine size of same power is less, and weight is lighter, and vibration and noise are lower, have greater advantage.

The movement characteristic of rotary engine is: when revolve round the sun around the output shaft center in the center of three-apexed rotor, three-apexed rotor itself is again around its center rotation.When three-apexed rotor rotates, be the ring gear at center and be the gear engagement at center with the three-apexed rotor center with the output shaft center, gear is fixed on the cylinder body and does not rotate, and ring gear is 3: 2 with the ratio of the number of teeth of gear.Above-mentioned kinematic relation makes the movement locus (being the shape of cylinder wall) on three-apexed rotor summit like the figure of eight.Three-apexed rotor is divided into three separate space to cylinder, and three spaces are successively finished air inlet, compression, acting and exhaust separately, and three-apexed rotor is from circling engine ignition acting three times.Because above kinematic relation, the rotating speed of output shaft is 3 times of rotor speed of autorotation, and this piston with the reciprocating motion type motor is different fully with 1: 1 kinematic relation of bent axle.

Because three-apexed rotor side and casing wall adopt the Stamping Steel Ribbon of similar piston ring that firing chamber and axle are sealed, the thickness of Stamping Steel Ribbon generally has only 1mm, because the position of Stamping Steel Ribbon relation, make the degree of depth of closure gasket groove generally need 5mm, rotor with the 200CC discharge capacity is an example, need 300 minutes process time approximately, and the machining period expense just needs 300 yuans, and this has just increased processing cost.

Since rotor center be equipped with one with cylinder body between cooperates the internal gear that rotates, need firm position and relative angle necessary correct between this gear and the rotor, existing design is to fix with a plurality of elastic opening pins in both cooperation places, and difficulty of processing and cost are all higher.

In sum, existing three-apexed rotor has processed complex, and shortcomings such as cost height have hindered the popularization and the development of three-apexed rotor simultaneously.
