Abstract
The utility model provides a vane-type pneumatic motor which comprise a shell, a stator, a rotor, end covers and vanes, wherein the stator is arranged inside the shell, the rotor is arranged in the stator through a front bearing and a rear bearing and provided with a vane slot, the end covers are arranged at two ends of the stator, and the vanes are embedded in the vane slot of the rotor; the stator and the rotor are eccentrically arranged; three air guide holes are arranged at the rear end of the shell of the motor, wherein the two air guide holes are air inlet holes, the other one is a main exhaust hole which is arranged at the maximum eccentric part of the stator and the rotor, and three air guide grooves which are circumferentially and evenly distributed at the upper edge of the stator and communicated with the air guide holes and the bottoms of the vanes. The utility model reduces the appearance size of the motor, ensures that the motor is light, handy and attractive under the condition of ensuring the motor power, ensures that the rotation speed of the motor is greatly increased due to twice exhausting, and prolongs the service life of the motor.
Description
[technical field]
The utility model relates to a kind of pneumatic motor, particularly a kind of compact structure, light weight, the pneumatic vane motor that volume is little, rotating speed is high.
[background technique]
Pneumatic vane motor, be to be prime mover of working medium with pressurized air, it is the expansion that utilizes pressurized gas, can change into pressure the power plant of mechanical energy, generally by shell, cover, stator, rotor, blade, front and rear cover, bearing, locating stud, lining, thrust ring, parts such as adjusting screw are formed, form an active chamber between stator, rotor, after pressurized gas enters active chamber, pressure can produce moment of torsion on blade, make the rotor rotation work done, and gas is discharged body after the work done, by control valve, can change and turn to.
Existing pneumatic vane motor antero posterior axis bearing is eccentric, and two inlet holes that protrude upward are arranged on the motor case, and one of them is an inlet hole, and another is an exhaust port; This motor has determined that from structure its volume ratio is bigger, and rotating speed is low, because the structure that this motor body carried is too many, causes motor bulky.On motor rotary speed, because existing pneumatic motor has only an exhaust port, so exhaust for once.Pneumatic motor is by the gas acting of expanding in an eccentric structure, this structure with general pneumatic motor, when gas expand into the maximum eccentric place, owing to there is not exhaust port, motor continues rotation, so gas begins to be compressed smaller volume, cause the pressurized air part energy that enters motor to be cancelled, so motor rotary speed is low.
[model utility content]
Goal of the invention of the present utility model is: a kind of compact structure, light weight, volume is little, rotating speed is high pneumatic vane motor are provided.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of pneumatic vane motor, comprise shell, enclosure stator, by front and back bearings be installed in the rotor that has blade groove in the stator, stator two ends end cap, embed the blade in the described rotor vane groove, described stator and rotor eccentricity setting, described motor case rear end has 3 gas ports, wherein two is inlet hole, one is the main exhaust hole, the maximum eccentric place at stator and rotor is opened in described main exhaust hole, and circumferentially all the step has 3 gas guide grooves also and bottom gas port and the blade to communicate in the stator upper edge.
This motor is placed on the motor case rear end with port, can dwindle the motor external dimension like this; Motor stator is made off-centre, avoids general sliding-vane motor like this because antero posterior axis bearing off-centre causes the inconsistent motor failure that occurs of processing that adds front and back bearings seat eccentricity in man-hour; Under certain volume, motor stator lengthening, excircle size decreases then, thereupon, motor antero posterior axis bearing is then corresponding to diminish.This improvement makes motor become light and handy, attractive in appearance under the situation that guarantees motor power.
This novel motor is than the more than once exhaust of general sliding-vane motor, because the increase of air displacement is greatly improved motor rotary speed.There are 3 holes this motor case rear end, and two is the control clockwise and anticlockwise, and one is the main exhaust hole.Come to determine to insert as required from which hole.Maximum eccentric place at the stator of this novel pneumatic motor has increased several rows of pore, carries out the exhaust first time, motor rotation then, and another inlet hole then carries out the exhaust second time as secondary exhaust port.By twice exhaust, the pneumatic motor rotating speed is obviously improved.
After the vanes pressurized gas blows out in the blade groove, form several sealed compartments in that motor stator is inner,, in blade groove, freely stretch so motor rotates the back because stator interior is an eccentric structure.
The beneficial effects of the utility model are: under the situation that guarantees motor power, motor is lighter and handier, attractive in appearance, and this novel motor has twice exhaust, and motor rotary speed is greatly improved, and has improved the working life of motor.

Fig. 1 is that the utility model master looks sectional view.
Fig. 2 is the A-A sectional view among Fig. 1.
Fig. 3 is the left view of Fig. 1.
Mark among the figure: 1 is shell, and 2 is rear bearing, and 3 is rotor, and 4 is stator, and 5 is fore bearing, and 6 is end cap, and 7 is gas port, and 8 is gas guide groove, and 9 is blade, and 10 is blade groove, and 11 is suction port, and 12 is relief opening.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
As shown in Figure 1, a kind of pneumatic vane motor, comprise shell 1, the stator 4 of enclosure, be installed in the rotor that has blade groove 10 3 in the stator by fore bearing 5 and rear bearing 2, the end cap 6 at stator two ends, embed the blade 9 in the described rotor vane groove, described stator 4 and rotor 3 eccentric settings, described motor case rear end has 3 gas ports 7, wherein two is inlet hole 11, one is main exhaust hole 12, the maximum eccentric place at stator and rotor is opened in described main exhaust hole, and circumferentially all the step has 3 gas guide grooves 8 also and bottom gas port and the blade to communicate in the stator upper edge.
During work, the disclosed motor of the utility model is than the more than once exhaust of general sliding-vane motor, because the increase of air displacement, motor rotary speed is greatly improved, there are 3 holes this motor case rear end, two control clockwise and anticlockwise, one is the main exhaust hole, can come as required to determine to insert, increase several rows of pore, carry out the exhaust first time at the maximum eccentric place of the stator of this novel pneumatic motor from which hole, motor rotation then, another inlet hole then carries out the exhaust second time as secondary exhaust port, by twice exhaust, the pneumatic motor rotating speed is obviously improved, after the vanes pressurized gas blows out in the blade groove, at the several sealed compartments of the inner formation of motor stator,,, in blade groove, freely stretches by motor so rotating the back because stator interior is an eccentric structure.
