Abstract
The utility model relates to an impeller with adjustable angles for a mine axial flow fan. The utility model is characterized in that blades are connected with small conical gears by connecting rods of the blades, and each small conical gear is evenly distributed on a shaft sleeve of a gear box and connected with the shaft sleeve by threads. A large conical gear is meshed with each small conical gear and connected to a rotating shaft of a fan through a fastening rod which is fixedly connected with the rotating shaft of the fan, and the large conical gear is compressed by a compressing nut after connected with the fastening rod by the threads. The utility model has the advantages that angles of the blades can be conveniently adjusted and air volume of a work face is arbitrarily changed and simultaneously also has the characteristics of energy saving and noise reduction.
Description
The utility model relates to a kind of mining axial fan angle adjustable impeller.Be specially adapted to the accessory of colliery axial flow portable blower main body.
Existing mining portable blower fan blade and main body combine as a whole, and can not adjust working surface institute required airflow can not be regulated owing to its fan blade, and the capacity of idle power consumption of motor is big, and efficient is low, and the incidence of disease of operating worker is also higher.
The purpose of this utility model is at above-mentioned shortcoming of the prior art, and a kind of face air volume that can change arbitrarily is provided, and has and adjust simple, energy-conservation and reduce the mining axial-flow blower angle adjustable impeller of noise.
The purpose of this utility model is achieved in that a kind of mining axial fan angle adjustable impeller, it is by fan blade, wheel hub, the fan blade link rod, large conical gear, small conical gear, gear-box is formed, the axle sleeve of gear-box is enclosed within on the axle head of fan shaft, the number of small conical gear is identical with the number of fan blade, small conical gear be distributed on the axle sleeve of gear-box and with axle sleeve be scyewed joint, large conical gear and the engagement of each small conical gear, and be connected in the rotating shaft by anchorage bar, compress by gland nut after large conical gear and the anchorage bar scyewed joint, anchorage bar and rotating shaft on axial direction for being fixedly connected, wheel hub is screwed on gear-box, it is scyewed joint that the fan blade link rod passes behind the wheel hub perisporium with small conical gear, and fan blade is riveted on the top of fan blade link rod.
The number of teeth of large conical gear is 60, and the number of teeth of small conical gear is 10.The number of small conical gear is 8-10.
On the axle sleeve end face of gear-box, be provided with the tapped hole of 2 symmetries.
On the wheel hub of large conical gear, be fixed with pointer.
Working principle of the present utility model is as follows:
Fan blade of the present utility model and fan blade link rod, small conical gear link together, small conical gear and large conical gear engagement, when transferring large conical gear with special tool, the helical thread portion of small conical gear lower end rotates with large conical gear, thereby make all fan blade angles all along with change, screw gland nut when being transferred to required angle and large conical gear and small conical gear are nibbled tightly get final product.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
By Fig. 1, embodiment shown in 2 as can be known, the utility model is by fan blade 1, wheel hub 2, fan blade link rod 3, large conical gear 11, small conical gear 5, gear-box 6 is formed, the axle sleeve 9 of gear-box 6 is enclosed within on the axle head of fan shaft 12, the number of small conical gear is identical with the number of fan blade, small conical gear be distributed on the axle sleeve of gear-box and with axle sleeve be scyewed joint, large conical gear 11 and each small conical gear engagement, and be connected in the rotating shaft 12 by anchorage bar 13, compress by gland nut 14 after large conical gear 11 and anchorage bar 13 scyewed joint, anchorage bar 13 and rotating shaft 12 on axial direction for being fixedly connected, wheel hub 2 is screwed on gear-box, fan blade link rod 3 is scyewed joint with small conical gear 5 after passing the wheel hub perisporium, and fan blade 1 is riveted on the top of fan blade link rod.
The number of teeth of large conical gear is 60, and the number of teeth of small conical gear is 10.
The number of small conical gear is 8-10.
On the axle sleeve end face of gear-box 6, be provided with the tapped hole 10 of 2 symmetries, so that the disengage gear case.
On the wheel hub of large conical gear, be fixed with pointer 8.
In Fig. 1,4 is tightening nut, and 7 is jump ring.
The utility model has the advantages that and in the extremely short time, to regulate easily fan blade angle, change arbitrarily Become the air quantity of working face, and effectively change shaft power and reached energy-conservation purpose and reduced and made an uproar Sound. It can also be widely used in the axial fan of other type except being applicable to mine local fan.
