Abstract
The utility model relates to a motor rotary shaft with a flexible connecting piece. The utility model is provided for the purpose of providing a motor component which has the advantages of convenient alignment, favorable engaging and transmitting performance, stable motion, little resistance and long service life. The utility model comprises a shaft rod and a transmission rod, wherein the shaft rod penetrates and is connected to the shaft center of the motor, the transmission rod is engaged with a drive gear, the periphery of the transmission rod is provided with transmission screw threads and the flexible connecting piece is arranged between the shaft rod and the transmission rod which are connected through the flexible connecting piece connected in series between the shaft rod and the transmission rod.
Description
The utility model belongs to motor component, particularly a kind of machine shaft with flexible connector.
As shown in Figure 1, known automobile electric window motor 1 center is equipped with elongated axostylus axostyle 10, and an end of axostylus axostyle 10 is placed through among the drive mechanism 3A that connects with motor 1.The leading portion of axostylus axostyle 10 is provided with the screw drive section 11 that protrudes out outside the motor 1, and axostylus axostyle 10 is by the driven wheel 3B engagement of screw drive section 11 with drive mechanism 3A.So, when motor 1 axostylus axostyle 10 rotates, through the screw drive section 11 of its leading portion drive and with the drive mechanism 3A that the driven wheel 3B of its engagement drives, rise or descend with traction transmission bar, make the motorized window lifting.But, when the axostylus axostyle 10 that is positioned at motor 1 axle center is in the quick rotation state, because of this its is elongated axostylus axostyle, when causing its quick rotation, its front end produces the situation of swing because of centrifugal action, thereby make mesh because of the back lash is excessive between the screw drive section 11 that is in leading portion and the driven wheel 3B incomplete, thereby the useful life that causes motorized window transmission shakiness, sends allophone and reduce drive mechanism 3A easily; Moreover owing to as being to be connected between the motor 1 of power source and the passive device by axostylus axostyle 10 cross-under string groups, each member is when assembly, often because of the scale error in each member manufacture process, can not involutory really rigging error when causing assembly, friction between axostylus axostyle 10 and the drive mechanism 3A assembly element very easily taking place and increase rotary resistance, increases the operating current of motor 1; The processing of excessive and drive mechanism 3A outer cover is bad because of offset error again, and under long-term frictional dissipation operating state, the coefficient of friction increase of each inter-module causes the bigger resistance of motion, produces and disturbs people's noise, even the transmission bar can't be moved.
The purpose of this utility model provides and a kind ofly aligns conveniently, the engaged transmission performance is good, the motion stabilization resistance is little, the machine shaft with flexible connector of long service life.
The utility model comprises that running through the axostylus axostyle that is arranged in electrical axis reaches the drive link that meshes with driven wheel; The drive link periphery is provided with motion thread; Be equipped with flexible connector between axostylus axostyle and the drive link; Axostylus axostyle and drive link connect with the flexible connector that is serially connected with between the two.
Wherein:
Axle end is arranged with storage tank; The end that drive link is relative with axostylus axostyle is arranged with storage tank; The two ends of flexible connector insert group respectively are fixedly connected in the storage tank of axostylus axostyle and drive link end.
Flexible connector is to fixedly connected with axostylus axostyle and drive link with the recessed edge in location that the winding place punching press of axostylus axostyle and drive link forms nick at it.
The serve as reasons hawser of many steel wire coil coileds of flexible connector inside, its periphery ring is around the steel wire ring spring of one deck bundle system hawser.
Because comprising, the utility model runs through axostylus axostyle that is arranged in electrical axis and the drive link that meshes with driven wheel; The drive link periphery is provided with motion thread; Be equipped with flexible connector between axostylus axostyle and the drive link; Axostylus axostyle and drive link connect with the flexible connector that is serially connected with between the two.During use, run through the axle center that is arranged in motor with axostylus axostyle of the present utility model, and make its drive link wear group with connect the driving seat that is located at motor one side joint with the driven wheel engagement that drives in the seat, to drive the action of electric motor of automobile window.When there is foozle in the member of combo and center line can't be consistent the time, can compensate by the flexible connector that connects axostylus axostyle and drive link, make drive link still can keep engagement really with driven wheel, wear and tear, increase the bad phenomenon of the operating current of resistance when avoiding the assembly transmission, not only align conveniently, the engaged transmission performance is good, and little, the long service life of motion stabilization resistance, thereby reach the purpose of this utility model.
Fig. 1, establish the electric motor of automobile window driving apparatus structural representation cutaway view of known machine shaft for group.
Fig. 2, be the utility model decomposition texture schematic isometric.
Fig. 3, be the utility model structural representation stereogram.
Fig. 4, establish electric motor of automobile window driving apparatus structural representation cutaway view of the present utility model for group.
Below in conjunction with accompanying drawing the utility model is further elaborated.
As Fig. 2, shown in Figure 3, the utility model 4 comprise run through the axostylus axostyle 40 that is arranged in motor 2 axle center, and the drive link 41 of driven wheel 31 engagements and be serially connected with axostylus axostyle 40 and drive link 41 between flexible connector 42.
The serve as reasons hawser 420 of many steel wire coil coileds of flexible connector 42 inside, its periphery ring is around the steel wire ring spring 421 of one deck bundle system hawser 420.
During assembling, distinguish insert group in the storage tank 400,410 of axostylus axostyle 40 and drive link 41 ends with the two ends of flexible connector 42, form the recessed edge 43 in location of nick then in the flexible connector 42 and the winding place punching press of axostylus axostyle 40 and drive link 41, flexible connector 42 is fixedly connected between axostylus axostyle 40 and the drive link 41, forms the utility model 4.
During use, as shown in Figure 4, run through the axle center that is arranged in motor 1 with the axostylus axostyle 40 of the utility model 4, and make its drive link 41 wear group with connect the driving seat 3 that is located at motor 1 one side joints with driven wheel 31 engagements that drive in the seat 3, to drive the action of electric motor of automobile window.
The utility model 4 has the following advantages in assembling and use:
1, be connected in series with flexible connector 42 between the axostylus axostyle 40 of the utility model 4 and the drive link 41 after, punching press is located recessed edge 43 and is closed the location admittedly again, each component sets complexion easily, fast, in conjunction with stable.
2, by the flexible connector 42 of the utility model 4, member when combo, as drive the seat 3, there is foozle and center line can't be consistent the time, can compensate by the flexible connector 42 that connects axostylus axostyle 40 and drive link 41, make drive link 41 still can keep engagement really, wear and tear, increase the bad phenomenon of the operating current of resistance when avoiding the assembly transmission with driven wheel 31.
