Abstract
The utility model discloses a device for connecting an outer rotor motor and fan blades, which comprises the outer rotor motor (1) and the plurality of fan blades (2), wherein the plurality of fan blades (2) are mounted and connected with an outer ring (3); inner threads are formed on the inner wall of the outer ring (3); an inner ring (4) is sleeved outside the outer rotor motor (1); outer threads are formed on the outer surface of the inner ring (4); and the outer ring (3) is sleeved outside the inner ring (4) and in threaded connection with the inner ring (4). By adopting the device, the concentricity of the outer ring and the plurality of fan blades is guaranteed, the technology has low difficulty and can be easily implemented, the inner ring is then sleeved outside the outer rotor motor, the outer threads are formed on the outer surface of the inner ring, and the outer ring is sleeved outside the inner ring and in threaded connection with the inner ring. By adopting the structure, the concentricity of the motor, the inner ring, the outer ring and the plurality of fan blades can be easily guaranteed, and the plurality of the fan blades are easily guaranteed to be coplanar, so that the motor property has a stable performance and longer operation life.
Description
Technical field:
The utility model relates to the jockey of a kind of external rotor electric machine and fan blade.
Background technology:
The jockey of existing external rotor electric machine and fan blade has two kinds, a kind of is that fan blade directly is welded on the shell of external rotor electric machine, because technological reason, the bad assurance of concentricity, cause fan blade off-centre and influence the motor performance instability, and the multi-disc fan blade is difficult to guarantee coplane during the fan blade welding, influences overall performance; Another kind of external rotor electric machine is fitted in (the fan blade mounting bracket can not be welded earlier before press-fiting) with sleeve, then at sleeve outside welded and installed support, fan blade is installed on the mounting bracket by bolt and nut, same principle, in mounting bracket when welding, be difficult to guarantee coplane and cause off-centre easily, causes fan blade eccentric and influence the motor performance instability.
Summary of the invention:
The purpose of this utility model provides the jockey of a kind of external rotor electric machine and fan blade, its good manufacturability, and fan blade is installed by the back fan blade and motor installation concentricity guarantees easily, guarantees that motor performance is stable, and the multi-disc fan blade guarantees coplane easily during the fan blade welding.
The purpose of this utility model is achieved by following technical proposals.
The jockey of a kind of external rotor electric machine and fan blade, comprise external rotor electric machine and some air blades, some air blades are installed and are connected on the outer collar, the outer collar inwall is provided with internal thread, the outside of external rotor electric machine is set with inside race, the inside race outer surface is provided with external screw thread, and outer collar is enclosed within the inside race outside and is threaded mutually.
Above-mentioned described external rotor electric machine comprises stator module, rotor assembly, base and rotating shaft, and stator module is installed on the base, and rotor assembly is enclosed within the stator module outside, and an end of rotor assembly and rotating shaft couples together, and rotating shaft is rotatable to be installed on the base.
Above-mentioned described inside race is fitted in rotor assembly outside and rotor assembly interference fit.
Above-mentioned described some air blades are installed in and are installed in respectively on some connection supports, and some connection supports evenly are welded on the outer surface of outer collar.
The utility model compared with prior art, has following effect: 1) earlier some air blades installations are connected on the outer collar, can guarantee the coplane of some air blades by the frock clamp of special use, and guarantee the concentricity of outer collar and some air blades easily, technology difficulty is little, realize easily, the outside of external rotor electric machine is set with inside race then, the inside race outer surface is provided with external screw thread, outer collar is enclosed within the inside race outside and is threaded mutually, therefore, adopt the said structure external rotor electric machine, inside race, the concentricity of outer collar and some air blades guarantees easily, some air blades guarantee coplane easily, thereby guarantee that motor properties is stable, prolongs working life; 2) adopt screw thread to install, installs easylier, as long as screw, and it is opposite with the external rotor electric machine direction of rotation that the screw thread rotation direction is installed, and the air blade installation tightly.3) angle of inclination of the air blade on the outer collar, shape can be adjusted, therefore can produce multiple outer collar with differing tilt angles and difform air blade, but outer collar is the same with the fit dimension of inside race, therefore, the versatility of motor is stronger, changes differing tilt angles and difform air blade ratio and is easier to.
