Detailed description of the invention
In order to make those skilled in the art be more fully understood that this utility model, below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 illustrates the exploded view of the linear actuator 100 according to this utility model embodiment.Fig. 2 illustrates the profile of the linear actuator 100 according to this utility model embodiment.
Linear actuator 100 is suitable for installing such as between ground and seat, receive motor message code (such as representing the signal moving certain distance to certain direction), under the control of motion controller, driving the motor of linear actuator 100, linear actuator 100 produces translation axially.Here motor message code is intended to and the mobile linear actuator in image and/or synchronous sound ground, and then moved seat, brings kinesthesia to experience to the spectators on seat.
Linear actuator 100 includes motor 1, screw mandrel 9, motor coupler 3 and screw mandrel shaft coupling 6, bearing 7, the Part I 5 of 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 has can the output shaft 101 of bidirectional rotation.
Output shaft 101 and the screw mandrel 9 of motor are linked up by motor coupler 3 and screw mandrel shaft coupling 6, pass to screw mandrel 9 with the bidirectional rotation by the output shaft of motor 1.
In the example presented in the figure, motor coupler 3 and screw mandrel shaft coupling 6 are linked together by cross jointer 4.Motor coupler 3 and screw mandrel shaft coupling 6 are respectively provided with two prominent finger pieces, are used for being fitted in cross jointer 4.The material of cross jointer 4 can be elastomeric material.But it is only for example, motor coupler 3 and screw mandrel shaft coupling 6 can link together by other means.
Screw mandrel shaft coupling 6 is plateau form, closely cooperates with screw mandrel 9, and its nose portion has prominent finger piece.
In this example, shell includes Part I 5 and the Part II 20 that can axially take apart, is motor cabinet 5 hereinafter referred to as Part I 5, and claiming Part II is screw mandrel housing.Motor cabinet is connected with motor, for instance by connecting the screwed hole on the boss of motor 1 and the corresponding screwed hole 102 on motor cabinet with bolt 2；Screw mandrel is mostly held in screw mandrel housing 20.In the example illustrated in figure 1, motor cabinet 5 has square profiles, and screw mandrel housing 20 has circular profile.
Hereinafter, all parts are called near-end near one end of motor, and the one end away from motor is called far-end.
Bearing 7 is for support screw 9.Bearing 7 is enclosed within screw mandrel shaft coupling 6.The near-end of bearing 7 is limited by the inner chamber shoulder of the far-end of motor cabinet 5, and the far-end of bearing 7 is limited by the shoulder of the inner chamber of the near-end of screw mandrel housing 20.Additionally, the far-end of bearing 7 also adopts round nut 8 to fix.In other words, the far-end of motor cabinet 5 has stepped hole, the side laminating of the near-end of the step surface (end face) of stepped hole and the outer ring of bearing 7, the near-end of screw mandrel housing 20 has the projecting ends of annular, the end face of this projecting ends withstands the side of the far-end of the outer ring of bearing, and the side face of the stepped hole of the outer circumference surface of this projecting ends and motor cabinet 5 closely cooperates.Screw mandrel shaft coupling 6 has flange 61, withstands the first side of the inner ring of bearing in the side of flange away from the side of motor, and the second side of the inner ring of bearing is fixed by nut.
The form of bearing 7 does not limit, it is possible to adopt the bearing of any suitable type such as ball bearing.
Linear actuator also has the coaxial filament stem nut 11 and sliding tube 12 that are rigidly attached to one.Feed screw nut 11 has the part 111 being positioned at sliding tube 12 and the flange 112 being positioned at outside sliding tube 13.Flange 112 tightens together with sliding tube 12, for instance by bolt 10.Feed screw nut 11 can with screw mandrel 9 screw-threaded engagement, thus the rotary motion of screw mandrel 9 being converted to the translation of feed screw nut 11, thus driving sliding tube 12 to carry out translational motion relative to the inner chamber of described shell.
In the example illustrated in figure 1, the screw mandrel housing parts 20 of shell has pin 15, this pin 15 is contained in the sliding cavity 121 of sliding tube 12 when assembling, in case the rotation of sliding stop pipe 12, also it is prevented that the rotation of feed screw nut 11, thus ensure that the feed screw nut 11 translational motion together with sliding tube 12.
In the example illustrated in figure 1, label 13 indicates crashproof pad, and label 14 indicates hexagon socket countersunk flat cap head screw.The effect of crashproof pad 13 and sunk screw 14 is to prevent feed screw nut and screw mandrel from departing from when moving to end.
In the example illustrated in figure 1, label 17 indicates cylinder body inner sleeve, and cylinder body inner sleeve 17 is made by high-abrasive material, is embedded on screw mandrel housing 20, with sliding tube 12 relative motion.
In the example illustrated in figure 1, screw mandrel housing 20 has hole 15, is adapted as steam vent and spanner impetus, and making screw mandrel housing 20 internal by aerofluxus is malleation, and makes to be easy to operation as spanner impetus, it is easy to installs, dismantle and adjusts.
In the example illustrated in figure 1, screw mandrel housing 20 end is connected to lid 18, it is illustrated that in lid 18 is fixed to screw mandrel housing 20 by screw 10.
In linear actuator shown in above-mentioned Fig. 1, shell is divided into motor cabinet part and screw mandrel housing parts so that be easy to assembling, and motor cabinet part and screw mandrel housing parts can limit bearing；Additionally nut portion is positioned at outside sliding tube, has flange, it is easy to assembling, saves part.
The method dismantling linear actuator according to this utility model embodiment is described below, it is possible to including:
First, the connection member being connected by motor 1 is removed with the Part I of shell, for instance remove screw 2.
It follows that remove motor 1.
Then motor cabinet part 5 is removed.
Last from the Part II of shell, namely the inner chamber of screw mandrel housing parts 20 integrally pulls out secondary part, described secondary part includes at least one bearing 7 interconnected amongst one another, screw mandrel 9, feed screw nut 11 and sliding tube 12.
The method of the dismounting linear actuator according to this utility model embodiment can pull down secondary part with comparalive ease, it is simple to maintenance and replacing.
Above example repeatedly using screw as the example of connection member, but is only for example in describing, and those skilled in the art can select other connection member as required.
Being described above each embodiment of the present utility model, described above is illustrative of, and non-exclusive, and it is also not necessarily limited to disclosed each embodiment.When not necessarily departing from the scope and spirit of illustrated each embodiment, many modifications and changes will be apparent from for those skilled in the art.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
