Abstract

The invention provides a washer motor, comprising rotor and shaft, where equispaced grooves are arranged in the fitting position of the rotor and the shaft and the shaft fits the inner hole of the rotor; the grooves on the shaft and the shaft are formed by single extension. And its obvious effect: it solves the problem that rotor torque is on the low side. As a load is larger, this shaft is mostly used to generate enough large torque, generally used in full auto washer motors; and the generated torque is larger and the vertical load is heavy, and besides, it improves working performance of washer.

Description

Motor for washer
Technical field
The present invention relates to a kind of motor, particularly be used in the motor for washer on the single container washing and extracting machine.
Background technology
Single container washing and extracting machine are different from general two-tub washing machine, and two-tub washing machine is to drive by two motors, and laundry is in a bucket, with laundry type motor-driven; Dehydration use the dehydration-type motor-driven in another bucket, obey with this laundry washer, washes in the washing tub to take in the dehydration behind the clothes to dewater again.And single container washing and extracting machine have only a bucket, and such washing machine can dewater after washing clothes immediately.As shown in Figure 1, motor shaft design on single container washing and extracting machine, be on the motor shaft of the Rotor Assembly structure of single container washing and extracting machine and rotor fixed position, generally all to adopt the annular knurl mode, on hydraulic press, with certain pressure motor shaft is pressed in the rotor hole, both are interference fit, and are heavy in order to produce certain moment of torsion or normal load.It is on the low side moment of torsion often to occur with the beam warp of annular knurl shape, and normal load is heavy defective, simultaneously, adopts the processing of annular knurl mode, requires the process conditions rate of exchange height of processing, and the annular knurl cost is also high, and it is heavily low to occur normal load easily, does not reach the requirement of technical indicator.
Summary of the invention
The purpose of this invention is to provide a kind of motor for washer, by to the motor shaft of this motor and the change of rotor fixed position structure, increase the cooperation moment of torsion, it is heavy to improve normal load.
For achieving the above object, technical scheme of the present invention provides a kind of motor for washer, comprises the rotor and the motor shaft of motor, wherein: be provided with equally spaced groove on described motor shaft and position that described rotor cooperates, should cooperate with the endoporus of described rotor.
Groove on the described motor shaft and motor shaft are the one-off drawing moulding.
The full-automatic laundry machine motor axle of present production that effect of the present invention is this structural change adopts the annular knurl mode more, has solved rotor torque problem on the low side with the axle of groove structure.When duty ratio is big, adopt this axle to be used for producing enough big moment of torsion more, generally be used on the motor of single container washing and extracting machine,
It is bigger to change over groove mode torsion, and normal load is heavy high, has also improved the service behaviour of washing machine simultaneously.
Description of drawings
Fig. 1 is the Rotor Assembly structural representation of prior art;
Fig. 2 is a Rotor Assembly structural representation of the present invention;
Fig. 3 is a motor shaft structural representation of the present invention.
Among the figure:
1. rotor 2,8. motor shaft
3. keyway 4. annular knurl spacing shims
5. fixed position annular knurl 6. snap ring stopper slots
7. fixed position groove
Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated motor for washer of the present invention.
Shown in Fig. 2,3, the structural improvement of motor for washer of the present invention is that the annular knurl mode on the original motor axle is processed the groove mode that makes into, can one-shot forming, and processing not only cut down finished cost, and the normal load anharmonic ratio is bigger than being easier to.This motor for washer comprises the rotor and the motor shaft of motor, is provided with equally spaced groove 7 on described motor shaft 8 and position that described rotor 1 cooperates, and this 1 cooperates with the endoporus of described rotor 1.Groove 7 on the described motor shaft 8 is one-off drawing moulding with motor shaft 8.
Motor for washer of the present invention is assembling like this:
Be used for putting snap ring stopper slot 6, rigid bearing is with groove 7 protruding parts, and just motor shaft 8 and rotor 1 secure fit position are used for placing annular knurl spacing shim 4, adjust between the bearing apart from keyway 3, be used for installing the Impeller fan page or leaf, drive the rotation of clutch with belt.About full-automatic laundry machine motor, general requirement has very strong carrying load ability, be that rotation torque numerical value is big, the general annular knurl mode that adopts, more than the rotor rotation torque 6Kg.m, and laundry type and dehydration-type motor are low comparatively speaking, general adopt optical axis just can, the rotation torque requirement of rotor is more than 2.5Kg.m.
On hydraulic press, earlier motor shaft 8 is inserted in the hole of rotor 1, be placed on the supporting mould, supporting mould is a boss with holes, that of rotor 1 band fan page or leaf is sidelong on boss, and the boss cylindrical can be avoided in the motor shaft process of press in than smaller several millimeters of rotor fan page or leaf root diameter (RD), rotor is to two side shiftings, and boss hole is bigger than the diameter of motor shaft.After everything is ready, Push switch, the hydraulic press top mould will be pressed into motor shaft in the rotor hole with certain pressure, the endoporus and motor shaft 8 grooves 7 positions of rotor 1 are cooperated, boss mould role is not only the support rotor plane, can also play the perpendicularity that keeps rotor and motor shaft, avoid the generation of rotor side-sway.It is tightr just to be that than the benefit of annular knurl mode rotor and motor shaft cooperate with the groove mode, and the groove mode processes easily, and one-shot forming, is convenient to detect, and has increased the rotation torque between rotor and the motor shaft.

Claims (2)

1, a kind of motor for washer comprises it is characterized in that the rotor and the motor shaft of motor:
On described motor shaft (8) and position that described rotor (1) cooperates, be provided with equally spaced groove (7), should (1) cooperate with the endoporus of described rotor (1).
2, motor for washer according to claim 1 is characterized in that: the groove (7) on the described motor shaft (8) is the one-off drawing moulding with motor shaft (8).
