Abstract
The invention relates to a fixing structure for a motor holder. The fixing structure comprises a motor housing provided with a stator and a rotor therein, and two or more fixing holders symmetrically distributed on the outer wall of the motor housing, wherein the fixing holder is formed by a fixing plate with a through-hole and a connection plate vertically connected with one end of the fixing holder and having certain curvature. In the inventive motor holder fixing structure, the connection plate of the fixing holder has the cambered surface design with the same curvature radius as that of the motor housing, and the connection plate and the motor housing are in contact and soldered, so that the soldering of the connection plate and the motor housing is not easy to crack. The connection plate and the fixing plate are vertically soldered in arc-shape, so as to delay the occurrence of fatigue endurance limit, and improve the service life of the motor fixing holder.
Description
Technical field
The invention belongs to the motor technique for fixing, particularly relate to the fixing structure for motor supporter of a kind of fixed support and motor casing strong bonded.
Background technology
In general in motor for continuous rotation, adopt commutator-rectifier, the effect of commutator-rectifier is exactly that the electric current of receiving is changed successively, makes rotor can be rotated with certain direction in any position.
Monophase machine in the past includes the inboard of the motor casing that is formed with the inner space and is fixing stator; The inboard of stator is provided with the inner peripheral surface of stator and is keeping certain distance, the rotor that can be rotated; Its centre of rotor portion is inserted with rotating shaft; On the both side ends of rotating shaft bearing is being set, its bearing is fixed by motor casing 1 and guiding fan sheet, makes rotating shaft be rotated.
Being provided with the AC current conversion that will supply with at the upside of rotor is the commutator-rectifier of DC electric current; The both sides of commutator-rectifier are provided with the outside of commutator-rectifier is flexible and contact, to commutator-rectifier provide power supply and and a pair of carbon brush of rotating shaft vertical direction formation;
The downside of the motor casing of motor is being fixed the bearing that guiding fan sheet fixes supporting rotating shaft, is fixedly installing the fan of introducing air on the rotating shaft below guiding fan sheet, and fan below in conjunction with fan cover.Symmetry is uniform on the motor casing outer wall is formed with two and plural fixed support.
The solid support of motor in the past normally is made of the fixed head and the connecting plate of " ┙ " shape.Forming because connecting plate is the straight line flat board, therefore, is that the point of contact contacts with the motor casing combination, faying face is a straight line, in motor long-term operation vibration, can cause the faying face of connecting plate and motor casing to snap, also can cause fatigue fracture between connecting plate and the fixed head, influence electrical machinery life.
Summary of the invention
The present invention provides the fixing structure for motor supporter of a kind of fixed support and motor casing strong bonded for solving the technical problem that exists in the above-mentioned technology.
The technical scheme that the present invention takes for the technical problem that exists in the above-mentioned technology of solution is:
A kind of fixing structure for motor supporter among the present invention comprises that its inside is provided with the motor casing of stator, rotor; Uniform two and the plural fixed support that is formed on the motor casing outer wall of symmetry; Fixed support by the fixed head that has through hole with one of the vertical connecting plate that is connected and is certain radian of end form.The radius of curvature of fixed support connecting plate is identical with the radius of curvature of motor casing; The radius of curvature that fixed support fixed head and fixed support connecting plate connect the radius of curvature of an end and fixed support connecting plate is identical.
Advantage and good effect that the present invention has are: fixing structure for motor supporter of the present invention, the fixed support connecting plate adopts the cambered surface design identical with the radius of curvature of motor casing, make connecting plate contact welding with the motor casing face, make connecting plate and motor casing be not easy to snap, the vertical welding with the fixed head arc of connecting plate has delayed the appearance of fatigue limit, the life-span of having improved motor fixed rack.

Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Fig. 1 is the schematic diagram of motor casing of the present invention and support bracket fastened combination, and Fig. 2 is the schematic top plan view of motor casing of the present invention and support bracket fastened combination, and Fig. 3 is the stereogram of motor fixed rack of the present invention, and Fig. 4 is the vertical view of motor fixed rack of the present invention.
Monophase machine includes the motor casing 1 that is formed with the inner space; Stator is being fixed in the inboard of motor casing 1; The inboard of stator is provided with the inner peripheral surface of stator and is keeping certain distance, the rotor that can be rotated; Its centre of rotor portion is inserted with rotating shaft; On the both side ends of rotating shaft bearing is being set, its bearing is fixed by motor casing and guiding fan sheet, makes rotating shaft be rotated.
Being provided with the AC current conversion that will supply with at the upside of rotor is the commutator-rectifier of DC electric current; The both sides of commutator-rectifier are provided with the outside of commutator-rectifier is flexible and contact, and provide power supply to commutator-rectifier, and and a pair of carbon brush that forms of rotating shaft vertical direction.
The downside of the motor casing 1 of motor is being fixed the bearing that guiding fan sheet fixes supporting rotating shaft, is fixedly installing the fan of introducing air on the rotating shaft below guiding fan sheet, and fan below in conjunction with fan cover.Uniform two and the plural fixed support 2 that is formed on the motor casing outer wall of symmetry on motor casing 1 outer wall.
Shown in Fig. 1-4, a kind of fixing structure for motor supporter among the present invention comprises that its inside is provided with the motor casing 1 of stator, rotor; Uniform two and the plural fixed support 2 that is formed on the motor casing outer wall of symmetry; Fixed support 2 by the fixed head 4 that has through hole with one of the vertical connecting plate 3 that is connected and is certain radian of end form; The radius of curvature of fixed support connecting plate 3 is identical with the radius of curvature of motor casing 1; The radius of curvature that fixed support fixed head 4 and fixed support connecting plate 3 connects the radius of curvature of an end and fixed support connecting plate 5 is identical.
Adopt fixing structure for motor supporter of the present invention, because connecting plate 3 forms the radius of curvature identical with the radius of curvature of motor casing, contact welding with motor casing 1 formation face, make connecting plate 3 and motor casing 1 be not easy to snap, the vertical welding with fixed head 4 arcs of connecting plate 3 has delayed the appearance of fatigue limit, the life-span of having improved motor fixed rack.If establish one to two reinforcement again at connecting plate 3 and fixed head 4 welds, can make fixed support 2 more firm.
