Abstract
A fan assembly with reinforcing ribs comprises fan blades and a fan shaft sleeve. The fan blades are riveted with the fan shaft sleeve, and the reinforcing ribs are arranged on the surfaces of the fan blades. The fan assembly has the advantages of capabilities of improving the strength of the fan blades, decreasing the weight of the fan blades, reducing the production cost of the fan blades, lowering noise, prolonging the service life of the fan assembly and further enhancing work precision and reliability of a whole fan.
Description
Technical field
The utility model relates to the fan component that a kind of gas gun uses.
Background technique
Usually, an internal-combustion engine is housed in the gas gun, this internal-combustion engine provides fuel by a gas tank that communicates with the firing chamber.Be provided with ignition mechanism in the firing chamber, also dispose a fan in the firing chamber, this fan is by motor driving, and its effect is: one, guarantee even, the fully burning of burning indoor air and fuel mix; Two, be convenient to burn discharge and each parts of firing chamber of back waste gas cool off faster.
Behind ignited fuel, the blast of fuel makes piston assembly produce acceleration, thereby promotes the piston work done.Simultaneously, the blast meeting of fuel produces a reaction force and recoil to fan and motor.After standing these reciprocal active forces, fan and motor can produce the to-and-fro motion with respect to the firing chamber main body, so that the fan blade distortion, add the speed motor fatigue ruption.Common solution is the thickness that increases saw lumber, adopts harder material.
The problem that exists is: the to-and-fro motion of fan component, can cause the fan blade distortion, and destroyed the dynamic balancing of fan component, increased the noise of motor, reduced the working life of motor and even complete machine; Common thickened material or can increase cost of production with hard material.
Summary of the invention
For the problem that the motor noise that distortion brought, cost of production height, the machine life that solves existing gas gun fan component detracts, the utility model proposes a kind of fan blade that improves fan component intensity that has.
The utility model adopts following technological scheme:
The fan component that has stiffening rib comprises fan blade and fan axle sleeve, it is characterized in that: described fan blade and the riveted joint of described fan axle sleeve, the surface of described fan blade is provided with stiffening rib.
Has a stiffening rib at least on each fan blade.
Technical conceive of the present utility model is: fan blade is riveted on fan shaft puts, and go out stiffening rib on fan blade in riveted joint.
When fan component is subjected to external impacts along fan axial direction double vibrations,, improved the intensity of fan blade by the stiffening rib on the fan blade.Fan blade elastic deformation amount diminishes, and also makes the fatigue strength of fan component rise the life-span of having improved fan component.Can use simultaneously thin, lighter material, alleviate leaf weight, also reduce cost of production.Under identical impact force action, reduced the resiliently deformable of fan blade, can reduce impact force to the dynamically balanced destruction of fan component, thereby reduce the noise that produces when fan blade is rotated.
The beneficial effects of the utility model are: the strength enhancing of (1) fan blade is obvious, and improve the working life of fan component; (2) weight reduction reduces cost; (3) reduce noise.

Embodiment
With reference to Fig. 2, Fig. 3
The fan component that has stiffening rib comprises fan blade 1 and fan axle sleeve 2, described fan blade 1 and described fan axle sleeve 2 riveted joints, and the surface of described fan blade 1 is provided with stiffening rib 3.
A stiffening rib 3 is arranged on each fan blade 1.
Technical conceive of the present utility model is: fan blade 1 is riveted on the fan axle sleeve 2, and goes out stiffening rib 3 on fan blade 1 in riveted joint.
When fan component is subjected to external impacts along fan axial direction double vibrations,, improved the intensity of fan blade by the stiffening rib on the fan blade.Fan blade elastic deformation amount diminishes, and also makes the fatigue strength of fan component rise the life-span of having improved fan component.Can use simultaneously thin, lighter material, alleviate leaf weight, also reduce cost of production.Under identical impact force action, reduced the resiliently deformable of fan blade, can reduce impact force to the dynamically balanced destruction of fan component, thereby reduce the noise that produces when fan blade is rotated.
With reference to Fig. 4, Fig. 5
Present embodiment and embodiment's one difference part is: two stiffening ribs 3 are arranged on each fan blade 1.
The described content of this specification embodiment only is enumerating the way of realization of model utility design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
Claims (2)
1. the fan component that has stiffening rib comprises fan blade and fan axle sleeve, it is characterized in that: described fan blade and the riveted joint of described fan axle sleeve, the surface of described fan blade is provided with stiffening rib.
