Abstract
The utility model discloses a novel elastic connector of a motor. The novel elastic connector comprises a spline sleeve and two couplers, wherein both ends of the spline sleeve are provided with inner splines, one ends of the couplers are provided with outer splines, of which one ends are situated in the inner splines, and the couplers are in cooperative connection with the inner splines at both ends of the spline sleeve. The novel elastic connector overcomes the defects that a conventional connecting shaft of a motor rotor shaft and an encoder is easy to break and short in service lifetime. The novel elastic connector is simple in structure, convenient in connecting means and long in service lifetime.
Description
Technical field
The utility model belongs to the Motor connecting device field, is specifically related to a kind of novel motor Flexible Connector.
Background technology
When motor moves, the form of the mechanical force and moment that machine shaft is suffered is different with the difference of motor type and transmission mechanism, active force mainly contains: the gravity of rotor assembly self, the unbalanced force that rotor eccentricity causes, the centrifugal force of uneven weight, the shaft extension end acts on load torsional moment on axle etc. by gearing.Therefore, the rotating shaft of motor should have enough intensity, to guarantee that motor does not produce residual deformation or damage with the processing axis in working order, simultaneously, rotating shaft also will have enough rigidity, at present, between rotor and encoder, for d-axis connects, when rotor and encoder rotation, d-axis can be because moment of torsion overstep the extreme limit and cause fracture in rotation process, perhaps because the extruding of axial force surpasses the breakage that the limit of d-axis causes, make the useful life of motor short.
The utility model content
The technical problems to be solved in the utility model is for short defective of connecting axle frangibility, the useful life of existing rotor axis of electric and encoder, provide a kind of simple in structure, connected mode is easy, avoid fractureing, a kind of novel motor Flexible Connector of long service life.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of novel motor Flexible Connector, comprise spline housing and two shaft couplings, wherein, the two ends of spline housing are equipped with internal spline, one end of shaft coupling is provided with external splines, and external splines one end of two shaft couplings is positioned at spline housing, and is connected by the internal spline at external splines and spline housing two ends.
adopt a kind of novel motor Flexible Connector of technical solutions of the utility model, because the two ends of spline housing are equipped with internal spline, one end of shaft coupling is provided with external splines, external splines one end of two shaft couplings is positioned at spline housing, and the internal spline by external splines and spline housing two ends is connected, be positioned at spline housing thereby the external splines axle head that makes two shaft couplings is relative, a shaft coupling connects armature spindle, another connects encoder, when rotor and encoder rotation, send the moment of torsion that rotates to shaft coupling, because with the shaft coupling of external splines and being connected with the internal spline spline housing, and external splines and internal spline can coordinate rotation, thereby the fracture of avoiding moment of torsion to overstep the extreme limit causing, extended useful life.
Further, a kind of novel motor Flexible Connector wherein, also is provided with keyway in described shaft coupling.Arranging of keyway better makes coupling together of shaft coupling and armature spindle and encoder.
Further again, a kind of novel motor Flexible Connector wherein, is provided with spacing ring between the internal spline at described spline housing two ends.Spacing ring is in order to limit moving axially of shaft coupling, and the position that makes shaft coupling be provided with internal spline at spline housing two ends moves axially.
adopt a kind of novel motor Flexible Connector of technical solutions of the utility model, the external splines end of two shaft couplings is relative, cooperate together with the internal spline at spline housing two ends, two shaft couplings are connected with armature spindle by one inner, keyway, one is connected with encoder, armature spindle and encoder are coupled together, when armature spindle and encoder rotation, because external splines and internal spline can arbitrarily rotate around the axle center, in addition, armature spindle and encoder can be in spline housing the internal spline position move axially, thereby satisfy the extruding buffering of axial force, therefore, two shaft couplings can rotate around the axle center in spline housing and move axially, thereby the fracture of avoiding surpassing torque limit and axial force extruding and causing, extend the useful life of motor.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model motor Flexible Connector, comprise spline housing 2 and two shaft couplings 1, wherein, the two ends of spline housing 2 are equipped with internal spline, one end of shaft coupling 1 is provided with external splines, and the internal spline at the external splines of two shaft couplings 1 and spline housing 2 two ends is connected; Also be provided with keyway 4 in described shaft coupling 1; Be provided with spacing ring 3 between the internal spline at described spline housing 2 two ends.
in specific implementation process, the external splines end of two shaft couplings 1 is relative, cooperate together with the internal spline at spline housing 2 two ends, two shaft couplings 1 are connected with armature spindle by 4 one inner, keyway, one is connected with encoder, armature spindle and encoder are coupled together, when armature spindle and encoder rotation, because external splines and internal spline can arbitrarily rotate around the axle center, spacing ring 3 makes shaft coupling 1 rotor driven axle and the encoder internal spline position in spline housing 2 move axially, thereby satisfy the extruding buffering of axial force, therefore, two shaft couplings 1 can rotate around the axle center in spline housing 2 and move axially, thereby the fracture of avoiding surpassing torque limit and axial force extruding and causing, extend the useful life of motor.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
