Description
Technical field
The utility model relates to speed reducer technical field, more specifically relates to the spline hub connecting structure of a kind of effective protection motor, easy-to-mount reducing motor.
Background technique
Reducing motor refers to the conglomerate of speed reducer and motor.This conglomerate also can be described as gear motor or gear motor conventionally.Conventionally by professional speed reducer factory, carry out after integrated assembling, with the complete supply of material of motor integral.
Existing reducing motor is all that motor shaft is goed deep in speed reducer, and then small gear is installed on motor shaft, can reduce like this overall volume of reducing motor.But so just bring a problem, general motor shaft diameter is all smaller, and motor shaft is communicated to motor internal, and the load meeting that small gear bears is directly passed on motor shaft, make motor shaft produce vibration, easily cause shaft break of motor or damage internal structure of motor; And this kind of structure be not easy to dismounting, whole reducing motor will be taken apart once break down, need specialized factory to open, waste time and energy, maintenance cost is high.
Model utility content
The utility model, for overcoming above-mentioned deficiency of the prior art, provides the spline hub connecting structure of a kind of effective protection motor, easy-to-mount reducing motor.
The utility model is achieved through the following technical solutions above-mentioned purpose.
A kind of spline hub connecting structure of reducing motor, comprise by speed reducer and motor together of bolt-locking, be horizontally set on the axle in speed reducer, one shaft end is provided with external splines, and external splines is combined with an inner spline housing, and the other end of inner spline housing is connected with the output axle key of motor.This programme is by increasing the cooperating structure of a pair of interior external splines; slow down greatly the impact of gear mesh motor shaft; effectively protect motor; and the overall volume increase of reducing motor is also few; the cooperating structure of interior external splines also has certain deviation compensation effect; even if the output shaft of motor and an axle have certain deviation; still can normally move; more importantly that this structure is convenient to dismounting; speed reducer and motor can be split once break down; check respectively, time saving and energy saving, reduce maintenance cost.
For simplified structure, an above-mentioned axle is one-level gear shaft.
Introduce a kind of reducing motor again, adopt the spline hub connecting structure of above-mentioned reducing motor, be also provided with secondary gear axle, tertiary gear axle and output shaft in above-mentioned speed reducer, the axis of output shaft and above-mentioned one-level gear shaft is on same straight line; On secondary gear axle, be fixed with one-level gearwheel, on tertiary gear axle, be fixed with secondary gearwheel, on output shaft, be fixed with three grades of gearwheels; The gear of one-level gear shaft engages with one-level gearwheel, and the gear of secondary gear axle engages with secondary gearwheel, and the gear of tertiary gear axle engages with three grades of gearwheels.This programme adopts three grades of slowing-down structures, and speed ratio can distribute more uniformly, and centre distance can reasonable Arrangement, and space hold is little, is especially applicable to the reducing motor of heavy-load type.
The utility model compared with prior art mainly has following beneficial effect: by increasing the cooperating structure of a pair of interior external splines, slowed down greatly the impact of gear mesh motor shaft, effectively protected motor; The cooperating structure of interior external splines also has certain deviation compensation effect, even if the output shaft of motor and an axle have certain deviation, still can normally move; Simple in structure, be convenient to dismounting, speed reducer and motor can be split once break down, check respectively, time saving and energy saving, reduce maintenance cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
For more succinct explanation the present embodiment, in accompanying drawing or explanation, some well known to a person skilled in the art but can omit to some extent with the incoherent component of main contents of this creation.For ease of statement, in accompanying drawing, some component has omission, zooms in or out, but does not represent size or the entire infrastructure of actual product in addition.
Embodiment 1:
As shown in Figure 1, a kind of spline hub connecting structure of reducing motor, comprises by speed reducer 1 and motor 2 together of bolt-locking, is horizontally set on the one-level gear shaft 3 in speed reducer 1.As shown in Figure 2, the end of one-level gear shaft 3 is provided with external splines.Again as shown in figures 1 and 3, external splines is combined with an inner spline housing 4, and the other end of inner spline housing 4 is connected with the output axle key of motor 2.Between inner spline housing 4 and casing, pass through oil sealing sealing, to improve sealing effect.
The present embodiment is by increasing the cooperating structure of a pair of interior external splines; slow down greatly the impact of gear mesh motor output shaft; effectively protected motor 2, the cooperating structure of interior external splines also has certain deviation compensation effect, even if the output shaft of motor 2 and one-level gear shaft 3 have certain deviation; still can normally move; be more importantly that this structure is convenient to dismounting, speed reducer 1 and motor 2 can be split once break down, check respectively; time saving and energy saving, reduce maintenance cost.
Embodiment 2:
As shown in Figure 4 and Figure 5, a kind of reducing motor, adopt the spline hub connecting structure of the reducing motor in embodiment 1, in speed reducer 1, be also provided with secondary gear axle 5, tertiary gear axle 6 and output shaft 7, the axis of output shaft 7 and one-level gear shaft 3 is on same straight line, the outside of speed reducer 1 is stretched out in one end of output shaft 7, for connecting other drive mechanism.
On secondary gear axle 5, be fixed with one-level gearwheel 8, on tertiary gear axle 6, be fixed with secondary gearwheel 9, on output shaft 7, be fixed with three grades of gearwheels 10; The gear of one-level gear shaft 3 engages with one-level gearwheel 8, and the gear of secondary gear axle 5 engages with secondary gearwheel 9, and the gear of tertiary gear axle 6 engages with three grades of gearwheels 10.
