Abstract
The impeller of the utility model is fixed on the middle shaft through nuts. One end of the middle shaft of the impeller is fixed with screw threads of the nuts and the other end is a driven plate; the clutch casing is fixed on the center of the casing on one side of the fan through rivets; the middle shaft of the impeller is fixed in the clutch casing through the bearing; the whole fan is fixed on the top handle of the motor through the clutch and the motor connection hole.
Description
Technical field
The utility model relates to a kind of blower fan, belongs to and is equipped with; The blower fan of clutch driven disc.
Background technique
Blower fan is a kind of tool of production that often uses in the middle of our daily life, the blower fan of form whatsoever, its form all is to produce wind-force by the rotation at the impeller of Fan casing inside, and the rotation of impeller mainly is that wheel shaft by the impeller center is by the external force driven rotary.The blower fan power take-off of prior art can only be fixed as blower fan power output, blower fan body and power output separation difficulty are provided; The wind speed of wind-force that blower fan provides, promptly the rotating speed of impeller is difficult to grasp minimum output quantity.So just bring a lot of inconvenience to use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of blower fan that clutch is housed, this blower fan that clutch is housed can separate with power take-off easily, also can guarantee to export the minimum wind speed of wind-force, thereby improve the utilization efficiency of blower fan power take-off and guarantee the lowest power that blower fan is exported.
The technical scheme in the invention for solving the technical problem is: impeller is fixed on the impeller axis by nut, one end of impeller axis is the fixing screw thread of impeller nut, the other end is the driven disc of clutch, clutch outer member is fixed on the centre of blower fan one side shell by rivet, in clutch outer member, whole blower fan is fixed on the motor by clutch and motor attachment hole the impeller axis by bearing fixing.
The beneficial effects of the utility model:, make blower fan can separate easily with power take-off because an end of impeller axis is installed by the clutch driven disc; The use of clutch has also guaranteed the lowest power of blower fan output.
Description of drawings
Below in conjunction with embodiment extremely accompanying drawing the utility model is described in further detail.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a side-looking part sectioned view of the present utility model.
1. is flow blower casings among the figure, 2. impeller, 3. rivet, 4. clutch outer member, 5. clutch and motor attachment hole, 6. clutch driven disc.
Embodiment
The user needs the utility model is connected on the power take-off that engaging and disengaging gear is installed by clutch and motor attachment hole (5) before use, and whole system is fixed, and can use then.Power take-off is owing to be equipped with clutch, so have only revolution when output unit to reach the minimum requirements of system design when above, clutch friction plate could contact with clutch driven disc (6), and then could impeller (2) rotate, blower fan could produce wind-force, so just guarantee the revolution of impeller (2), and then reached the requirement of the lowest power that guarantees blower fan output; Use up the back as long as with bolt on the motor attachment hole blower fan is separated with power take-off by the dismounting clutch, power take-off promptly can be used as him and uses, thereby reach the purpose that improves the power take-off utilization efficiency, and bring bigger convenience to the user.
Claims (3)
1. the blower fan that has clutch comprises flow blower casing, impeller, clutch outer member and clutch driven disc, it is characterized in that clutch outer member is fixed on the centre of blower fan one side shell by rivet.
2. the blower fan that has clutch according to claim 1, an end that it is characterized in that the draught fan impeller axis are the fixing screw threads of impeller nut, and the other end is the driven disc of clutch.
