Abstract
The invention discloses a belt protector of a negative-pressure air fan, which comprises a air fan body and a carriage installed on the air fan body, wherein a fan disc is fixedly installed on the carriage, impellers are movably installed on the fan disc, an electric motor is installed at the bottom of the air fan body, an electric motor V-belt pulley on the electric motor is connected with the air fan by a V belt, and the V belt comprises an upper V belt and a lower V belt; and the V belt between the electric motor V-belt pulley and the fan disc is provided with a belt protector. The invention solves the problems of easy looseness and side-to-side swing of the belt, and prolongs the service life of the belt.
Description
Technical field
The present invention relates to a kind of negative-pressure air fan belt protection device.
Background technique
At present, the general on the market negative-pressure air fan that is using, comprise blower fan body and the supporting frame that is installed on the body, be installed with fan blade on the supporting frame, be movably installed with fan blade on the fan blade, blower fan body bottom is equipped with motor, is connected by v belt between the motor Vee pulley V on the motor and the fan blade.This kind negative-pressure air fan is after using a period of time, it is loosening to occur v belt easily, and the fan blade that causes driving same power rotates needs increase power consumption, becomes flexible to cause v belt to swing again, thereby make the collision of v belt and fan blade easily and break belt, perhaps stave fan blade.
Summary of the invention
The object of the present invention is to provide a kind of negative-pressure air fan belt protection device, it is loosening easily to the invention solves belt, and the problem that swings has increased working life of belt.
In order to achieve the above object, technological scheme of the present invention is:
A kind of negative-pressure air fan belt protection device, comprise blower fan body and the supporting frame that is installed on the blower fan body, be installed with fan blade on the supporting frame, be movably installed with fan blade on the fan blade, blower fan body bottom is equipped with motor, be connected by v belt between motor Vee pulley V on the motor and the fan blade, v belt is made up of last v belt and following v belt; On the v belt between described motor Vee pulley V and the fan blade belt protection device is installed.
Described belt protection device comprises expansion tightening wheel support, expansion tightening wheel and spring; Wherein on the blower fan body expansion tightening wheel support is installed, offers chute on the expansion tightening wheel support, be movably installed with expansion tightening wheel on the expansion tightening wheel support, the v belt between motor Vee pulley V and the fan blade just is positioned on the pulley groove of expansion tightening wheel; And the axle on the expansion tightening wheel is movably fastened by pad and is installed on the chute, is connected with spring on the axle, and the other end of spring is fixed on the blower fan body.
2 inner side surfaces of described pulley groove are made into the inclined-plane with angle of inclination with the v belt coupling.
Described belt protection device is installed in the last v belt between motor Vee pulley V and the fan blade or descends the neutral position of v belt.
Beneficial effect of the present invention is: belt protection device of the present invention is installed in the neutral position between motor Vee pulley V and fan blade, the v belt in neutral position is the place of easy transverse judder, not only tightening belt but also can effectively prevent swinging of belt easily; Secondly pulley groove is stressed with the bi-side of v belt, can protect belt do not allow easily broken and prevent belt because of service time long back produce the phenomenon of becoming flexible.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of negative-pressure air fan belt protection device of indication of the present invention, as shown in Figure 1, comprise blower fan body 1 and the supporting frame 2 that is installed on the blower fan body 1, be installed with fan blade 3 on the supporting frame 2, be movably installed with fan blade 4 on the fan blade 3, blower fan body 1 bottom is equipped with motor 5, is connected by v belt between the motor Vee pulley V 6 on the motor 5 and the fan blade 3, and v belt is made up of last v belt 7 and following v belt 15; On the neutral position of the last v belt 7 between described motor Vee pulley V 6 and the fan blade 3 the belt protection device is installed.The belt protection device comprises expansion tightening wheel support 8, expansion tightening wheel 10 and spring 13; Wherein on the blower fan body 1 expansion tightening wheel support 8 is installed, offer chute 9 on the expansion tightening wheel support 8, be movably installed with expansion tightening wheel 10 on the expansion tightening wheel support 8, the v belt 7 between motor Vee pulley V 6 and the fan blade 3 just is positioned on the pulley groove 14 of expansion tightening wheel 10; And the axle 11 on the expansion tightening wheel 10 is movably fastened by pad 12 and is installed on the chute 9, is connected with spring 13 on the axle 11, and the other end of spring 13 is fixed on the blower fan body 1.2 inner side surfaces of described pulley groove 14 are made into the inclined-plane with angle of inclination with v belt 7 couplings; The belt protection device of present embodiment also can be installed in the neutral position of the following v belt 15 between motor Vee pulley V 6 and the fan blade 3.
During the negative-pressure air fan running, motor 5 drive v belt motions make fan blade 3 rotate and drive fan blades 4 rotations, make blower fan operate.Negative-pressure air fan belt protection device is owing to be subjected to the restoring force of spring 13; make axle 11 that a pulling force to the right be arranged all the time, it is slided to the right in chute 9, drive expansion tightening wheel 10 also has trend to the right; and make pulley groove 14 jack-up v belt, make v belt be in tensioned state all the time.This device can be avoided belt in use loosening, elongated owing to growing the back belt service time, and make belt swing.In movement process, just do not need to consume more electric energy, solved because of the elongated problem that causes belt to swing easily of belt simultaneously yet.
