Abstract
The utility model relates to a fan of a generator, in particular to a cooling fan of the generator. The fan of the generator comprises a round chassis of the fan, a truncated-cone-shaped boss is arranged in the center of the round chassis of the fan, an axle hole is arranged in the center of the truncated-cone-shaped boss, a star-teeth-shaped metal insert in arranged on the axle hole, 19 vertically arranged blades are uniformly distributed on the periphery of the surface of the round chassis of the fan, the inner ends and the outer ends of the blades are respectively connected with the edge of the chassis of the fan and the boss, the diameter Phi of the chassis of the fan is 173mm, the center line section of the cross section of each blade is an arc section and a straight line section, wherein the straight line section is positioned at the outer side of the chassis of the fan, the length L of the straight line section is 19.49mm, the arc section is positioned at the inner side of the chassis of the fan, and the radius R of the arc section is 14.65mm. Due to the fan of the generator adopting the technical scheme of the utility model, the air force of the fan can be increased, the fastening strength for shaft connection is improved, the vibration of the fan is reduced, and the heat conduction effect is good.
Description
Technical field
The utility model relates to a kind of radiation fan, relates in particular to a kind of radiation fan of generator.
Background technique
Generator is a kind of common dynamic power machine; Be provided with skeleton in the generator; The line bag is installed on the skeleton generating an electromagnetic field, and during powerful generator work, line bag heating value is very big; When temperature is too high, can influence the proper functioning of generator, therefore need the sink that radiating effect is good.At present the most frequently used sink is a fan, and the main shaft of generator amature is extended out, and installs Power generator fan.For the ease of making; Common Power generator fan adopts the plastic construction once-through more, and the air blade sheet is fixed on the card of fan chassis; The blade of fan adopts arc structure; Drive the fan rotation when alternator shaft rotates and produce air-flow, the heat that produces in the generator work is discharged, to reach heat radiation.But when using this structure heat radiation, because the air blade plate shape is a circular arc, wind-force is little, and it is not fine causing radiating effect; Simultaneously since fan near thermal source; Particularly rotor main shaft conducts to the retainer ring of fan with the generator internal heat, and the thermal expansion coefficient of plastic material is greater than the thermal expansion coefficient of metal rotating shaft, and the bolt joint is asynchronous and loosening because of expanding; Produce vibration when causing fan to rotate; Influence radiating effect, bigger vibration even can cause fan to come off, generator line bag burns because of dispelling the heat.
The model utility content
The technical problem that the utility model will solve provides a kind of wind-force that adds big fan, improves the tightness that axle connects, and reduces fan vibration, the Power generator fan of good heat conduction effect.
In order to solve the problems of the technologies described above, the utility model provides a kind of Power generator fan, includes circular fan chassis; The central authorities on described fan chassis are provided with the frustoconic shape boss, and described boss central authorities are provided with axis hole, and axis hole is provided with star dentation metal insert; 19 blades of vertically installing of evenly arranging on around the card on said fan chassis; The inside and outside two ends of blade join with boss and fan chassis edge respectively, and the diameter of phi on fan chassis is 173mm, and said leaf cross-section center line segment is that circular arc adds straightway; Wherein straightway is positioned at the outside on fan chassis; Its length L is 19.49mm, and arc section is positioned at the inboard on fan chassis, and its radius R is 14.65mm.
Adopt the Power generator fan of technique scheme to have following advantage, 1, because the axis hole on fan chassis is provided with the metal insert of star dentation; Than the conventional plastic fan; Can not occur because of the expansion coefficient difference with axle becomes flexible, improve the tightness that axle connects, the fan vibrations are also less; 2, circular arc adds the blade shape of straightway than traditional arc shaped blade, and its wind-force is bigger, and heat-conducting effect is better.
As preferred version, in order further to improve the bulk strength of fan, the opposing one side of described fan chassis and blade is provided with the reinforcement gusset of radial and axial distribution.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model Power generator fan;
Fig. 2 is the structural representation of looking up of the utility model Power generator fan;
Fig. 3 is the blade shape schematic representation of the utility model Power generator fan.
Embodiment
Like Fig. 1, shown in 2 and 3, the utility model provides a kind of Power generator fan, includes circular fan chassis 1; The central authorities on fan chassis 1 are provided with frustoconic shape boss 2, and boss 2 central authorities are provided with axis hole 3, and axis hole 3 is provided with star dentation metal insert 4; 19 blades of vertically installing 5 of evenly arranging on around the card on fan chassis 1, the inside and outside two ends of blade 5 respectively with boss 2 and fan chassis 1 side edge, the diameter of phi on fan chassis 1 is 173mm; Blade 5 cross-section center line segments are that circular arc adds straightway; Wherein straightway is positioned at the outside on fan chassis 1, and its length L is 19.49mm, and arc section is positioned at the inboard on fan chassis 1; Its radius R is 14.65mm, and the opposing one side of fan chassis and blade is provided with the reinforcement gusset of radial and axial distribution.
Above-described only is the preferred implementation of the utility model; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. Power generator fan is characterized in that: include circular fan chassis, the central authorities on described fan chassis are provided with the frustoconic shape boss; Described boss central authorities are provided with axis hole, and axis hole is provided with star dentation metal insert, 19 blades of vertically installing of evenly arranging on around the card on said fan chassis; The inside and outside two ends of blade join with boss and fan chassis edge respectively, and the diameter of phi on fan chassis is 173mm, and said leaf cross-section center line segment is that circular arc adds straightway; Wherein straightway is positioned at the outside on fan chassis; Its length L is 19.49mm, and arc section is positioned at the inboard on fan chassis, and its radius R is 14.65mm.
