Abstract

A kind of piston-rotating volume-varying mechanism, its effect mainly is that expansion energy is become rotation function or rotation function is become expansion energy.It is characterized in that four annular pistons move in a circle between stator and double rotor, piston divides on two groups of rotors that are embedded in respectively separately, every group rotor symmetry has two crankwheels to rotate with rotor, and with stator on ring gear engagement, slide in the chute of the crank block on the crankwheel on the main wheel wheel disc.When main wheel rotates, drive the crankwheel that is engaged in ring gear and rotate, make and do the variable speed rotation between two rotors, drive piston its volume is changed.Otherwise if expansion energy makes volume-variation, then main wheel rotates, and internal-combustion engine, pump, motor can be done by this mechanism.Its advantage is: simple in structure, and good manufacturability, useful ceramics manufacturing.Piston and rotor are not done backward rotation, do not have to impact, at a high speed, low-speed performance is stable.

Description

Piston-rotating volume-varying mechanism

The present invention relates to a kind of piston-rotating volume-varying mechanism, belong to field of mechanical technique.

Piston-rotating volume-varying mechanism mainly is to replace piston, connecting rod expansion energy to be become rotation function, or rotation function is become a kind of mechanism of expansion energy.It has piston and does not move reciprocatingly, at a high speed, low-speed running is stable, characteristic of simple structure.

The present invention realizes by the following method: four not a half annular pistons move in a circle between stator and double rotor, piston divides on two groups of rotors that are embedded in respectively separately, every group rotor symmetry has two crankwheels to rotate with rotor, and with stator on ring gear engagement, slide in the chute of the crank block on the crankwheel on the main wheel wheel disc.Move the crankwheel rotation that is engaged in ring gear when the main wheel rotation epoch, make and do the variable speed rotation between two rotors, and its volume is changed for moving piston rotation.Otherwise, if there is expansive force to make volume-variation between the piston, main wheel output rotation function then.

Concrete structure of the present invention is provided by following examples and accompanying drawing.

Fig. 1 is a plan view of the present invention, Fig. 2 sectional view.

Describe concrete structure of the present invention and principle in detail below in conjunction with accompanying drawing:

Piston-rotating volume-varying mechanism mainly by: 1 stator, 2 pistons, 3 double rotors, 4 crankwheels, 5 ring gears, 6 crank blocks, 7 main wheels are formed (seeing Fig. 1, Fig. 2).Four pistons (2) divide two groups, A-B is one group, C-D is one group, be embedded in respectively on the rotor (3) separately, two crankwheels (4) symmetric arrangement is arranged on each rotor, the center of circle of crankwheel and place rotor rotate with speed, and crankwheel and fixing ring gear (5) engagement slide in the wheel disc chute of the crank block on the crankwheel (6) on main wheel (7).When main wheel rotated, crank block moving crankwheel of generation rotated.Because crankwheel is engaged in fixing ring gear, and two adjacent crankwheel distance of center circle are changed regularly, then the pairing two-piston distance in the moving two crankwheel centers of circle of generation changes, and realizes the long-pending function of transfiguration.Otherwise, when volume being changed, then promote main wheel and rotate the output rotation function as if expansion energy.

This mechanism is during as pump or oil hydraulic motor, and double feed inlet and two outlets or triple feed inlet and three outlet symmetric arrangement make it stressed evenly.

This mechanism is during as internal-combustion engine, and suction port and relief opening separate with a piston in a side, and igniting or high pressure oil shower nozzle are at symmetrical suction port and relief opening opposite side, and four pistons are divided into four cylinders to volume, realizes air-breathing, compression, outburst, degassing function.

This mechanism's piston and two-spool acceleration of motion curve are sine or cosine, make each kinematic pair not have impact, motion steadily.

Advantage of the present invention shows as: simple in structure, volume is little, and transmission power is big. Good manufacturability, piston, cylinder useful ceramics material are made. Each movement parts does not move reciprocatingly, and do not have to impact, at a high speed, the low speed rotation stable performance. Piston seal performance is good, and is good in economic efficiency.
