| 2 Claims: Claim l.This actuator contains 2 discs where in one is up and the other is down; And the down disc is 2parted from Oto 270 degrees of that is one parted and 90 degree of that is one parted which are connected to each other by a fastener ;the bottom disc also comprises other parts such as piston groove, leakage groove , bearing groove, canals for transferring wind and oil and a place for placing appendix busch; other pieces are also used in this actuator ;one of them is appendix busch which its appendiesx are connected to piston and its other similar pieces are leakage grooves; which are connected to the bottom disc by 4 screws. Claim 2- according to Claim 1, the upper disc is a variable part and the design of this actuator gives us the opportunity to replace directly each part in any figure at the place of the upper disc; provided that it could lead to the possibility of creating bear groove and leakage groove and connecting the piston to them ; In this way, the actuator can rotate the substitute piece directly. |
Field : disclosing pneumatic and rotatory actuators
Background :
Rotatory actuators (motors )turn pressed fluid energy to rotatory motion. Inside of hydraulic motors comprises gear ; blade and piston or vane. Its geometric shape is like pomps, but the difference is that pomp pistons should rotate to create fluid flow . These actuators are used to create rotatory motions in angles less than 360 degree.
Summary
The current actuator is designed in a way to produce rotatory motions in both high and slow rate.
This actuator also functions with oil pressure (hydraulic) and wind pressure ( pneumatic). in addition , it can adjust its rotation with hydraulic and pneumatic pressure. one way to produce this advice is using 3-dimensional printer.
This actuator can be used in hydraulic and pneumatic systems, different kinds of robots like production robots and anywhere in hydraulic and pneumatic actuators which need rotatory actuators .This actuator comprises 2 discs, an Piston and a ball bearing ring which install on each other.
DETAILED DESCRIPTION
As it was said before , this disclousre relates to the field of rotatory pneumatic and hydraulic actuators.
This actuator comprises 2 discs , a ball bearing ring ,an appendix bush and 2 leak catcher.
The second disc is 2parted .It connects to the primary part by 2 fastener .
A screw Connects the primary disc to the piston.
A bearing groove is both on the primary disc and
The second disc., which is placed in the groove at the time of montaging the ball bearing ball.
2 leakages are connected to the bottom disc by a screw .they have the responsibility of leakaging between 2 discs.
2 inputs and outputs of oil or wind are placed under the bottom disc.
As you've seen in drawings , this actuator contains 2 inputs and outputs in the bottom of the second disc which places can be changed due to necessities.
This actuator works in a way that oil entrances to the second disc groove and forces pressure behind the piston, which causes the rotation of piston in groove and primary disc; that leads to rotatory motion.
As it is said before ,one of the best ways of producing in this actuator is using 3dimensional printer.
It is also possible to perform other ways of production such as powder Metallurgy or pressing in frame or even using some machines like lathe work or milling.
AS a whole this actuator can be used in pneumatic and hydraulic industries or any where else that needs rotatory actuator in these 2 industries like production machinery .agricultural machinery or hydraulic industry.
Advantages of this actuator is that this actuator in comparison to similar actuators needs less space. Beside that ,it can be be build in any size or material due to the situation.
Another advantage of this actuator is that it can be fixed in angular adjustment across the entire rotation area and its rotation range is over 360 degrees.
