Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of bearing, more particularly to a kind of small-sized electric machine bearing.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment, and its major function is the mechanical rotary body of support, is reduced
Coefficient of friction in its motion process.It is many at present to be equipped with miniature motor for the electric toy car that children play, pass through electricity
Pond drives toy car to motor, but miniature motor on the market typically in order to reduce cost be fitted without bearing or
Person has higher than the complicated cost of its bearing arrangement of higher-end.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided one kind is simple in construction to be had
Effect reduces the small-sized electric machine bearing of production cost.
The purpose of this utility model can be realized by following technical proposal：A kind of small-sized electric machine bearing, including outer ring,
Rolling element and retainer, described rolling element are arranged in outer ring by retainer, it is characterised in that described rolling element is two
The spherical structure of transverse plane, the central axial of the rolling element offer cylindrical bore, and the bottom of the outer ring is fixed with anti-
The base that only retainer drops out, snap ring is provided with the top of the outer ring, pressure ring, the snap ring are provided with above described snap ring
Outer face be provided with some latches, offered on described pressure ring it is some match with latch and neck, described snap ring, pressure
Matched between ring and outer ring by latch with neck and be fastened together.
The technique effect of this small-sized electric machine bearing is：When bearing is installed, the motor shaft of motor is from the axle on rolling element
Passed through at hole, relative to traditional roller bearing or deep groove ball bearing, this rolling element is single spherical structure, passes through retainer
It is installed in outer ring, both ends are fastened by base and pressure ring, and simple in construction, production cost is low.
In a kind of above-mentioned small-sized electric machine bearing, stopper slot is offered on described outer ring, is set on described snap ring
It is equipped with the spacer pin being engaged with stopper slot.The setting of the structure effectively can prevent snap ring from rotating.
In a kind of above-mentioned small-sized electric machine bearing, described snap ring, latch, spacer pin are integral type structure.The knot
Structure production can simply pass through pressing and bending straight forming.
Compared with prior art, this small-sized electric arbor has the advantages of can effectively reducing production cost simple in construction.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2, this small-sized electric machine bearing, including outer ring 1, rolling element 2 and retainer 3, rolling element 2 pass through
Retainer 3 is arranged in outer ring 1, and rolling element 2 is the spherical structure of end flat, and the central axial of rolling element 2 offers cylinder
Shape axis hole, the bottom of outer ring 1 are fixed with the base 4 for preventing retainer 3 from dropping out, and the top of outer ring 1 is provided with snap ring 5, on snap ring 5
Side is provided with pressure ring 6, and the outer face of snap ring 5 is provided with some latches 7, offered on pressure ring 6 it is some match with latch 7 and card
Groove 8, matched between snap ring 5, pressure ring 6 and outer ring 1 by latch 7 with neck 8 and be fastened together.
Further describe in detail, in order to prevent snap ring 5 from rotating, stopper slot 10 is offered on outer ring 1, is provided with and limits on snap ring 5
The spacer pin 9 that position groove 10 is engaged；It is simply by pressing and bending straight forming, snap ring 5, latch 7, spacer pin 9 to produce
Integral structure.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although outer ring 1, rolling element 2, retainer 3, base 4, snap ring 5, pressure ring 6, latch 7, card have more been used herein
The terms such as groove 8, spacer pin 9, stopper slot 10, but it is not precluded from the possibility using other terms.It is only using these terms
In order to more easily describe and explain essence of the present utility model；Being construed as any additional limitation is all and this
Utility model spirit is disagreed.
