Abstract
This invention discloses a ring fixing structure for a washing machine motor bearing including a motor shaft fixed at the center of a motor rotor, a bearing connected with the shaft, a spacing ring for limiting the bearing, in which, limiting cams are formed at the bearing on the shaft for clamping the spacing ring, which is a round plane sheet one with the shaft passing through, more than two spacing humps are set on the shaft and the ring fixing structure is processed with a broach cutting on the original shaft to heave the edge of the shaft to clamp the spacing ring.
Description
Technical field
The present invention relates to a kind of motor for washer.Particularly relate to a kind of simple in structure, the ring fixing structure of the motor bearing of washing machine that cost is low.
Background technology
Motor comprises being pressed into the rotor that is combined on the rotating shaft, keeps a determining deviation to make the rotor rotational stator with rotor.
Stator comprises iron core and coil.Wherein stator core comprises a plurality of spiral portions of protrusion and the groove that forms between each spiral portion.Coil is wound in the spiral portion of iron core.The form of each spiral portion and groove and size are consistent.When on the coil of stator, applying power supply, can form magnetic flux in the space between stator and rotor, and the form of the magnetic flux distribution in the space must just can help the requirement of motor properties and noise aspect according to the form distribution of sine wave.A plurality of coils that distributing on the iron core of stator, the magnetic flux that produces on each coil are overlapping with the form of sine wave.
Usually, rotor and motor shaft one are connected and are applied in the center of motor stator in air conditioner motor.
As shown in Figure 1, the motor shaft 2 and the rotor 1 of motor for washer are fixedly linked, and bearing 3 is enclosed within the two ends of motor shaft 2, and is positioned at the both sides of rotor 1.Distance between two bearing 3 has qualification, in order to carry out spacing to the distance between two bearings 3, usually all in the inboard of two bearings 3, be positioned at just that card has spacing snap ring 4 on the motor shaft 2 of a side of rotor 1, by spacing snap ring 4 two bearings 3 are fixed on institute's allocation of motor shaft 2, maintain a certain distance.
As Fig. 2, Fig. 3, shown in Figure 4, spacing snap ring 4 be shaped as the disc structure that has opening 9, its opening 9 is so that can enter in the formed space, spacing snap ring 4 centres motor shaft 2 from here, and also be formed with projection 10 on the inner peripheral surface of spacing snap ring 4, so that spacing snap ring 4 firmly is stuck on the motor shaft 2, reach the effect spacing to two bearings 3.
But the spacing snap ring 4 of said structure belongs to imported product, and the tariff cost of transportation is than higher, and then the enforcement production domesticization, but domestic product, and intensity can not satisfy the required requirement of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, the ring fixing structure of the motor bearing of washing machine that cost is low.
The technical solution adopted in the present invention is: a kind of ring fixing structure of motor bearing of washing machine, include the motor shaft that is fixed on the rotor center, and the bearing that is connected with motor shaft, also include and be used for bearing is carried out spacing spacing ring, motor shaft be positioned at bearing fixed position be formed with spacing preiection, be used to block spacing ring, thereby carry out spacing bearing.Described spacing ring is a planar wafer shape ring-type, and motor shaft is run through.Spacing preiection on the described motor shaft is provided with more than two.
The ring fixing structure of motor bearing of washing machine of the present invention on original motor shaft, is processed with broaching tool, make edge protuberance, the high spot at axle edge has played position-limiting action, can block the spacing ring of annular, can use homemade annular stop ring like this, reduce motor cost.

Embodiment
Describe the ring fixing structure of motor bearing of washing machine of the present invention in detail below in conjunction with the drawings and specific embodiments.
Fig. 5 is the structural representation that rotor of the present invention is connected with motor shaft and bearing; Fig. 6 is the structural representation of spacing ring of the present invention; Fig. 7 is the end view of Fig. 6; Fig. 8 is the structural representation that spacing ring of the present invention combines with motor shaft.
As shown in the figure, the ring fixing structure of motor bearing of washing machine includes the motor shaft 6 that is fixed on rotor 1 center; The bearing 3 that is connected with motor shaft 6, described bearing 3 is a ball bearing; Be used for bearing 3 is carried out spacing spacing ring 7; Motor shaft 6 be positioned at bearing 3 fixed position be formed with spacing preiection 8, be used to block spacing ring 7, thereby carry out spacing bearing 3.Spacing preiection 8 on the motor shaft 6 can be processed with broaching tool on the prior motor axle, be processed into structure as shown in Figure 8, make edge protuberance form spacing preiection 8, after the processing, the edge protuberance place of axle has just realized position-limiting action, has played the same function of former spacing snap ring.Spacing preiection 8 on the described motor shaft 6 is provided with more than two.Spacing preiection 8 can be symmetrical arranged.
Described spacing ring 7 is a planar wafer shape ring-type, and motor shaft 6 is run through.
The ring fixing structure of motor bearing of washing machine of the present invention, on the motor shaft be formed with spacing preiection on the fixed position, before bearing is installed, elder generation is enclosed within spacing ring on the motor shaft and limited projection is blocked, install and fix bearing again, like this, make spacing ring limit distance between two bearings on the motor shaft, the technology that guaranteed is required.
