Abstract
The invention relates to a rotational piston dual-axle air motor, belonging to the motor technique, which can solve the problems of present rotational piston air motor which can not output transmission by two axles and display the revolution and rotational speed. It fixes the cylinder piston of air motor via bearing on the crack eccentric axle; when the piston oscillating moves along the cylinder chamber and surrounding the crack eccentric axle to drive the rotation of crack, to form the rotational piston dual-axle air motor. The invention has two output axles to drive two devices synchronously, and when one axle is used to output transmission, another axle can display the revolution and rotational speed with revolution and rotational speed display, therefore, the air motor can realize nominal rotation and non-step speed regulation to enlarge the application range of air motor.
Description
Technical field:
The invention belongs to field of motors.
Technical background:
At present, the rotary-piston type single shaft gas motor that China has occurred, every gas motor can only provide a relevant device and rotate output, and can't show parameters such as revolution, rotating speed, thereby its application is very limited.
Summary of the invention:
The purpose of this invention is to provide the moving motor of a kind of rotary piston type double-shaft pneumatic, it not only can provide rotation output to two relevant devices by a motor simultaneously, and when a motor one end rotatingshaft rotates an equipment output, the rotatingshaft of the other end can be mixed revolution and the rotating speed that revolution counter and rotating speed display device show the gas motor, can make the specified rotation of gas motor like this and realize stepless speed regulation, increase its application area greatly.
The technical solution used in the present invention is: have with a tape guide key opening and in the opening both sides that inlet and outlet mouth and another are brought into, 2 cylinder barrels of relief opening are separately fixed at 2 band inner cores and the center has on the end plate of axis hole, thereby form half cylinder bodies of 2 band inner cores.Be fixed in cylinder center's wall axis hole with the eccentric shaft of bearing bent axle, form the circle tube piston of a band bent axle, piston can rotate around eccentric shaft and bent axle, have the guiding groove that can insert feather key on the center wall of cylinder piston, symmetry has the trapping mouth that can insert the trapping piece on the piston barrel of guiding groove both sides, and trapping mouth center line and guiding groove center line are on same center line.The two ends of bent axle are passed from the inner core of two and half cylinder bodies and end plate axis hole respectively, and the inner core of half cylinder body inserted in the cylinder of bent axle piston from two ends respectively, in the process of inserting, two trapping pieces are put into two trapping mouths on the piston cylinder respectively, and make trapping piece correspondence position between cylinder wall inlet and outlet mouth, make the inlet and outlet mouth be distributed in trapping piece both sides, feather key is put into the guiding groove of piston cylinder intermediate inner wall, feather key and trapping piece can be used bolt after then two and half cylinder bodies being closed up movingly.Wherein, cylinder barrel inner chamber radius equals piston cylinder radius and the bent tenon sum of bent axle, the piston cavity radius equals cylinder inner core radius and crankshaft crank sum, the trapping tile height is the poor of cylinder barrel inner chamber radius and cylinder inner core radius, the trapping mouth is with long on length and the piston, and width is less than piston trapping mouth width.So just formed rotary piston type double-shaft pneumatic motor, after air-flow entered motor from suction port, the piston on the bent axle just can drive bent axle and rotate along the to-and-fro motion of trapping piece with when crankshaft eccentric shaft moves.Bent axle can be a solid crankshaft, also can be tapped hollow crankshaft.
Description of drawings:
Fig. 1 is a sectional structure schematic representation of the present invention.Among Fig. 1: 1-band inner core lower end sheet, second cylinder barrel of 2-cylinder, second cylinder trapping piece of 3-, second cylinder inner core of 4-, 5-keyway that leads, the 6-crank, the 7-bent axle, 8-eccentric shaft, 9-cylinder piston, the 10-eccentric shaft bearing, 11-piston cylinder center wall, 12-feather key, 1 '-band inner core upper head plate, first cylinder barrel of 2 '-cylinder, 3 '-first cylinder trapping piece, 4 '-first cylinder inner core.
Fig. 2 is a plan structure schematic representation of the present invention, among Fig. 2: tube end-plate in the 1-band, 2-cylinder barrel, 3-trapping piece, 4-inner core, the 5-keyway that leads, 6-crank, 7-bent axle, 8-eccentric shaft, 9-cylinder piston, 10-eccentric shaft bearing, 11-piston cylinder center wall, 12-feather key
Embodiment:
As depicted in figs. 1 and 2, the lower end sheet 1 of band inner core is good with second cylinder barrel 2 usefulness bolt of cylinder, form second cylinder body of cylinder, the upper head plate 1 ' of band inner core is good with bolt with first cylinder barrel 2 ' of cylinder, form first cylinder body of cylinder, second cylinder body has guiding keyway 5, in keyway 5 both sides a suction port 13 and relief opening 14 is arranged respectively, first cylinder body has the inlet and outlet mouth symmetrical with second cylinder body, at the end plate 1 of upper and lower two and half cylinder bodies and 1 ' center axis hole is arranged respectively.The eccentric shaft 8 usefulness eccentric shaft bearings 10 of bent axle 7 are fixed in the center hole of center wall 11 of cylinder piston 9, form the circle tube piston of a band bent axle, cylinder piston 9 can rotate around eccentric shaft 8 and bent axle 7, the edge of the center wall of cylinder piston 9 has the cylindrical guiding groove that can insert feather key, symmetry has the trapping mouth that can insert trapping piece 3 and 3 ' on the piston barrel of guiding groove both sides, and trapping mouth center line and cylindrical guiding groove center line are on same center line.With the two ends of bent axle 7 respectively from last, pass in following 2 the half cylinder body end plate axis holes, and the inner core 4 and 4 ' of 2 half cylinder bodies inserted respectively in the cylinder of bent axle cylinder piston 9 from two ends, in the process of inserting, trapping piece 3 and 3 ' is put into two trapping mouths of piston cylinder respectively, make, advancing of second cylinder body, relief opening is distributed in trapping piece both sides, feather key 12 is put into the guiding groove of piston cylinder center wall 11, feather key 12 can be movingly with trapping piece 3 and 3 ', then two and half cylinder bodies are closed up, feather key 12 should be closed up in the guiding groove 5 of cylinder body when closing up, close up the back and will go up with bolt, following 2 half cylinder bodies are fixed.Wherein, cylinder barrel 2 inner chamber radiuses equal piston cylinder 9 radiuses and bent axle footstalk 6 sums, piston 9 inner chamber radiuses equal cylinder inner core 4 radiuses and crankshaft crank 6 sums, the trapping tile height is the poor of cylinder barrel 2 inner chamber radiuses and cylinder inner core 4 radiuses, the trapping mouth is with long on length and the piston 9, and width is less than piston 9 trapping mouth width.So just formed the rotary piston type double-shaft pneumatic motor shown in Figure 2 as Fig. 1, after air-flow entered motor from suction port, the piston 9 on the bent axle 7 more can drive bent axle 7 and rotate along the to-and-fro motion of trapping piece with when crankshaft eccentric shaft 8 moves.Bent axle can be a solid crankshaft, also can be spiral shell bent axle in the hollow arbor braid.
