Brief description of the drawings
Below in conjunction with accompanying drawing in the detailed description of the embodiment of the present invention, of the present invention these and/or otherAspect and advantage will become more to be known and is easier to understand, wherein:
Fig. 1 shows according to the exploded view of the linear actuator of the embodiment of the present invention.
Fig. 2 shows according to the profile of the linear actuator of the embodiment of the present invention.
Detailed description of the invention
In order to make those skilled in the art understand better the present invention, below in conjunction with accompanying drawing and specific embodiment partyFormula is described in further detail the present invention.
Fig. 1 shows according to the exploded view of the linear actuator 100 of the embodiment of the present invention. Fig. 2 illustratesAccording to the profile of the linear actuator 100 of the embodiment of the present invention.
Linear actuator 100 is suitable for installing for example between ground and seat, receives motor message generationCode (for example representing to move to certain direction the signal of certain distance), under the control of motion controller, drivesThe motor of moving linear actuator 100, linear actuator 100 produces the translation along axial direction.The motor message code be here intended to image and/or synchronous sound mobile linear actuator, Jin EryiMoving seat, brings kinesthesia to experience to the spectators on seat.
Linear actuator 100 comprise motor 1, screw mandrel 9, motor coupler 3 and screw mandrel shaft coupling 6,The Part I 5 of bearing 7, shell and Part II 20, coaxial feed screw nut 11 and sliding tube 12.
Motor 1 receives coron signal, converts thereof into the rotation output of respective direction. Motor 1 hasOutput shaft 101 that can bidirectional rotation.
The output shaft 101 of motor and screw mandrel 9 link up by motor coupler 3 and screw mandrel shaft coupling 6,So that the bidirectional rotation of the output shaft of motor 1 is passed to screw mandrel 9.
In examples shown, motor coupler 3 is connected by cross connector 4 with screw mandrel shaft coupling 6Together. Motor coupler 3 and screw mandrel shaft coupling 6 all have two outstanding finger pieces, for chimericIn cross connector 4. The material of cross connector 4 can be elastomeric material. But this is onlyExample, motor coupler 3 and screw mandrel shaft coupling 6 can link together by other means.
Screw mandrel shaft coupling 6 is boss form, closely cooperates with screw mandrel 9, and its outstanding end has outstandingFinger piece.
In this example, shell comprises Part I 5 and the Part II 20 that can axially take apart, belowMiddle title Part I 5 is motor cabinet 5, claims that Part II is screw mandrel housing. Motor cabinet is connected with motor,For example, by connect screwed hole on the boss of motor 1 and the corresponding screwed hole 102 on motor cabinet with bolt 2;Screw mandrel is mainly contained in screw mandrel housing 20. In Fig. 1 example shown, motor cabinet 5 have square outsideShape, screw mandrel housing 20 has circular profile.
Hereinafter, all parts are called near-end near one end of motor, are called far-end away from one end of motor.
Bearing 7 is for support screw 9. Bearing 7 is enclosed within on screw mandrel shaft coupling 6. The near-end of bearing 7 byThe inner chamber shoulder of the far-end of motor cabinet 5 limits, and the far-end of bearing 7 is by the inner chamber of the near-end of screw mandrel housing 20Shoulder limit. In addition it is fixing that, the far-end of bearing 7 also adopts round nut 8. In other words, motor cabinet5 far-end has stepped hole, the side of the near-end of the step surface (end face) of stepped hole and the outer ring of bearing 7Face laminating, the near-end of screw mandrel housing 20 has the protrusion end of annular, and the end face of this protrusion end withstandsThe side of the far-end of the outer ring of bearing, the week of the stepped hole of the outer circumference surface of this protrusion end and motor cabinet 5Face closely cooperates. Screw mandrel shaft coupling 6 has flange 61, and withstand the side away from motor in the side of flangeThe first side of the inner ring of bearing, the second side of the inner ring of bearing fixes by nut.
The form of bearing 7 does not limit, and can adopt the bearing of any adequate types such as ball bearing.
Linear actuator also has the coaxial filament stem nut 11 and the sliding tube that are rigidly connected to each other together12. Feed screw nut 11 has and is positioned at the part 111 of sliding tube 12 and is positioned at the flange outside sliding tube 13112. Flange 112 tightens together with sliding tube 12, for example, by bolt 10. Feed screw nut 11 canWith screw mandrel 9 screw-threaded engagement, thereby rotatablely moving of screw mandrel 9 converted to feed screw nut 11 translation, fromAnd drive sliding tube 12 to carry out translational motion with respect to the inner chamber of described shell.
In Fig. 1 example shown, on the screw mandrel housing parts 20 of shell, there is pin 15, this pin 15When assembling, be contained in the sliding cavity 121 of sliding tube 12, with the rotation of anti-skidding pipe 12, also just anti-Stop feed screw nut 11 rotation, thereby ensured the translational motion of feed screw nut 11 together with sliding tube 12.
In Fig. 1 example shown, label 13 is indicated crashproof pad, hexagonal countersunk head spiral shell in label 14 instructionsNail. The effect of crashproof pad 13 and sunk screw 14 is to prevent that feed screw nut and screw mandrel from moving to endIn time, departs from.
In Fig. 1 example shown, label 17 is indicated cylinder body inner sleeve, and cylinder body inner sleeve 17 is done by high-abrasive materialBecome, be embedded on screw mandrel housing 20, with sliding tube 12 relative motions.
In Fig. 1 example shown, screw mandrel housing 20 has hole 15, is suitable for as steam vent and spannerForce, making screw mandrel housing 20 inner by exhaust is malleation, and makes to be convenient to as spanner impetusOperation, is easy to install, dismantles and adjusts.
In Fig. 1 example shown, screw mandrel housing 20 ends are connected with lid 18, pass through screw in diagramLid 18 is fixed to screw mandrel housing 20 by 10.
In linear actuator shown in above-mentioned Fig. 1, shell is divided into motor cabinet part and screw mandrel housing sectionPoint, make to be convenient to assembling, and motor cabinet part and screw mandrel housing parts can limit bearing; Spiral shell in additionFemale part is positioned at outside sliding tube, has flange, is easy to assembling, saves part.
The following describes according to the method for the dismounting linear actuator of the embodiment of the present invention, can comprise:
First, remove the attaching parts that motor 1 is connected with the Part I of shell, for example, remove screw2。
Next, remove motor 1.
Then remove motor cabinet part 5.
Finally, from the Part II of shell, in the inner chamber of screw mandrel housing parts 20, integrally pull out followerPoint, described secondary part comprise each other interconnection at least one bearing 7, screw mandrel 9, feed screw nut 11 andSliding tube 12.
Can pull down with comparalive ease driven according to the method for the dismounting linear actuator of the embodiment of the present inventionPart, is convenient to maintenance and changes.
In exemplary description above, the repeatedly example using screw as attaching parts, but this is only for showingExample, those skilled in the art can select other attaching parts as required.
Below described various embodiments of the present invention, above-mentioned explanation is exemplary, not exhaustive, and be also not limited to disclosed each embodiment. Do not depart from illustrated each embodiment scope andIn the situation of spirit, many modifications and changes are all aobvious for those skilled in the artAnd easily see.
