It has rotation centerline and center of gravity, and including the ring portion provided with opening, it is characterised in that：The axle is additionally provided with split washer
Foot, the foot is positioned close at the opening of the ring portion and the center of gravity is located on the rotation centerline.
In addition, the utility model also proposes following attached technical scheme：
The ring portion is provided with inner edge and outer rim, and the opening is opened on the inner edge, and the outer rim has smooth circle
Arc.
The inner edge has geometric center, the geometric center be located at the rotation centerline on and with the center of gravity phase mutual respect
It is folded.
Tangential direction extension of the foot along the outer rim.
The axle split washer has symmetrical center line, and the center of gravity is located in the symmetrical center line.
The quantity of the foot is a pair and is to be symmetrical arranged relative to the symmetrical center line.
The foot extends downwardly from the opening of the ring portion.
The foot is generally conical shape.
The foot is integrally formed with the ring portion.
The foot is provided with the first outer surface, and the ring portion is provided with the second outer surface, first outer surface and described the
Two outer surfaces are coplanar.
A kind of motor of the axle split washer with any of the above-described technical characteristic, the motor is provided with rotating shaft, the axle
Rotatably it is set in the rotating shaft with split washer.
Compared to prior art, the utility model has the advantage of the axle split washer that it is provided, by close
Foot is set to come to weightening at opening and balance at the opening of its ring portion so that the center of gravity of the back-up ring is located at its rotation centerline
On, so as to will not be had undesirable effect to the dynamic balancing of rotor or rotatable parts, it will not also reduce production efficiency.
Brief description of the drawings
Fig. 1 corresponds to the plan view of the axle split washer of the utility model preferred embodiment.
Fig. 2 is Fig. 1 side view.
Embodiment
Technical solutions of the utility model are made with further nonrestrictive detailed below in conjunction with preferred embodiment and its accompanying drawing
Explanation.
Referring to Figures 1 and 2, corresponding to the axle split washer 1 of the utility model preferred embodiment, it is generally set in electricity
Rotate in the rotating shaft (not shown) of machine and together with rotating shaft, and with rotation centerline L, symmetrical center line C and center of gravity G.Tool
Body, the back-up ring 1 includes the ring portion 5 provided with opening 3.Ring portion 5 is provided with inner edge 7 and outer rim 9.Inner edge 7 has part-circular periphery shape, and
It is stuck on the groove of machine shaft.A pair of breach 11 are provided with the top of inner edge 7, and above-mentioned opening 11 is offered in its underpart,
This pair of breach 11 is located substantially at the upper and lower ends of inner edge 7 with above-mentioned opening 3.In addition, rotation centerline L is perpendicular to shown in Fig. 1
There is geometric center O, geometric center O to be the center of circle of the place circumference of inner edge 7 for paper plane where back-up ring 1, inner edge 7, described several
What center 0 is located on rotation centerline L and overlapped with the center of gravity G.Above-mentioned outer rim 9 has the circular arc of smoothing regulation,
This regular shape also allows for the production and manufacture of back-up ring 1.Corresponding to the utility model preferred embodiment, outer rim 9 it is a diameter of
12mm, a diameter of 6mm of inner edge 7.
In addition, axle split washer 1 is additionally provided with a pair of foots 13, this pair of foot 13 is positioned close to the opening 3 of ring portion 5
Place, and positioned at the both sides of opening 3.Specifically, tangential direction of this pair of foot 13 along the outer rim 9 is extended downwardly, and and ring
Portion 5 is integrally formed, and this pair of foot 13 is to be symmetrical arranged relative to the symmetrical center line C.Foot 13 substantially has taper,
Including foot inner edge 14 and foot's outer rim 16, this regular shape is also easy to processing and manufacturing.It is preferably real corresponding to the utility model
10 ° of angles of folder between example, Liang Ge foots inner edge 14 are applied, and are gradually opened downwards；And the minimum range between Liang Ge foots inner edge 14 is
5.3mm.15 ° of angles are pressed from both sides between the foot inner edge 14 of same foot 13 and foot's outer rim 16, and are gradually opened upwards；In addition, split washer 1
It is 12.5mm from the edge in ring portion 5 to the distance between the lower edge of foot 13.
In addition, foot 13 is provided with the first outer surface 15, and ring portion 5 is provided with the second outer surface 17, the first outer surface 15 and the
Two outer surfaces 17 is coplanar, so after the back-up ring 1 is assembled in rotating shaft, it is to avoid foot 13 and the miscellaneous part of motor are mutual
Interference, consequently facilitating the installation of back-up ring 1.Importantly, the setting of this pair of foot 13, equivalent to the weight added at opening 3
Amount so that the center of gravity G of back-up ring 1 is located on its rotation centerline L；It is further preferred, that center of gravity G also is located at symmetrically simultaneously in
On heart line C；By above-mentioned setting, back-up ring 1 of the present utility model after machine shaft or other rotatable parts is attached to, around
