Abstract
The utility model discloses a rotation-prevention direct-connected type motor, comprising a motor shell, a motor shaft and a support for fixing the motor; the motor shaft penetrates through the motor shell, a vibration-proofing ring is sheathed at the extending end of the motor shaft, the motor is fixed on the support by the vibration-proofing ring, and the support is provided with an inner arc which is identical with the outer profile of the vibration-proofing ring, and a bulge is arranged on the inner arc, and the bulge is embedded in the vibration-proofing ring. By adopting the structure, the motor can prevent relative rotation of the vibration-proofing ring and the support and can lead the vibration-proofing ring to better have vibration-proofing and steady functions; in addition, the structure is simple, the manufacturing is convenient and the cost is low.
Description
Technical field
The utility model relates to a kind of anti-rotation associated mode motor.
Background technology
Present associated mode motor is mainly used in air-cooled pipeline formula air conditioner, equipment such as small-sized furred ceiling wind cabinet.This motor has motor body, the motor body two ends are with bump protection ring and are fixed on the bearing, in order to prevent relatively rotating of bump protection ring and motor shaft, be provided with at the inner ring of bump protection ring and prevent structure in relative rotation, but ignored relatively rotating between bump protection ring outer ring and the bearing.
The utility model content
In order to overcome the defective that exists in the background technology, the utility model structurally improves, and a kind of anti-rotation associated mode motor is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor, the bearing that comprises motor casing, motor shaft and fixed electrical machinery, motor shaft runs through motor casing, the motor shaft external part is with bump protection ring, motor is fixed on the bearing by bump protection ring, described bearing has the interior circular arc that matches with the bump protection ring outline, and interior circular arc is provided with a projection, and this projection embeds into bump protection ring.
The beneficial effects of the utility model are: owing to adopted this structure, in the time of can preventing that motor shaft from rotating, the shockproof firm effect of bump protection ring is better brought into play in the relative motion of bump protection ring and bearing, and simple in structure, easily manufactured, and cost is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Wherein: 1, motor casing, 2, motor shaft, 3, bearing, 4, bump protection ring, 3-1, projection, 3-2, interior circular arc.
Embodiment
In conjunction with the accompanying drawings the utility model is further described now.Accompanying drawing is rough schematic view, basic system of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
As Fig. 1 a kind of motor shown in Figure 2, the bearing 3 that comprises motor casing 1, motor shaft 2 and fixed electrical machinery, motor shaft 2 runs through motor casing 1, stability when strengthening machine operation, be with bump protection ring 4 at motor shaft 2 external parts, motor is fixed on the bearing 3 by bump protection ring 4, described bearing 3 has the interior circular arc 3-2 that matches with bump protection ring 4 outlines, in order to prevent that bump protection ring 4 and bearing 3 from producing relative rotation, be provided with a protruding 3-1 under the center of circle of circular arc 3-2 in described, this projection 3-1 embeds into bump protection ring 4.
When machine operation, motor shaft 2 high speed rotating, bump protection ring 4 is down fixing protruding 3-1's, can overcome bump protection ring 4 and produce relative rotation with bearing 3, better brings into play shockproof firm effect, improves the operating efficiency of motor.
With above-mentioned foundation execution mode of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from the utility model technological thought.Technical scope of the present utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
