Description

The Effector that a kind of propeller fan movable vane established angle is regulated

Technical field

The utility model relates to a kind of improvement of Effector structure of propeller fan movable vane established angle adjusting.

Background technique

At present, axial fan movable vane established angle is regulated Effector, adopts the fluid transmission mostly, and its final controlling element is the oil hydraulic cylinder linear movement output.The device of this application liquid cylinder pressure has following shortcoming: 1, accuracy of manufacturing requires height, and initial cost is high.

2, need special device that high hydraulic medium is provided.

3, hydraulic medium pressure is difficult for keeping constant, makes Location accuracy not high.

4, need the high pressure oil sealing configuration, then require highlyer for revolving part, it is many that working service requires.

5, oil hydraulic cylinder is located on the rotor disk, has increased the fatigue stress of main shaft.

Summary of the invention

The utility model is exactly to the problems referred to above, the Effector that provides a kind of mechanical propeller fan movable vane established angle to regulate.

For realizing the above-mentioned purpose of the utility model; The utility model adopts following technological scheme; The utility model comprises the axial moving device with flexible rod; Described flexible rod links to each other with the sound conversion equipment, and the described sound conversion equipment of its structure outline comprises that an end with the fixing casing of flexible rod, is provided with the rotating shaft that the outside has bearing in the casing; The end of rotating shaft is stretched out by the casing the other end, and links to each other with transfer panel.

The beneficial effect of the utility model: 1, do not have high pressure oil, save the high pressure oil oil-servicing facilities, difficulty and the fault of also having avoided sealing to bring simultaneously.

2, high, the positioning stablity of mechanical transmission Location accuracy.

3, each component processing good economy performance has reduced initial cost.

4, the transfer panel of the utility model movable vane with ventilator is linked to each other, regulate the movable vane established angle in the time of can being implemented in the ventilator running, realize remote operation, also can when shutting down, regulate the movable vane established angle, the ability that adapts to different needs is strong.

5, easy to use, time saving and energy saving.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the user mode figure of the utility model.

Fig. 3 is that the A of Fig. 2 is to view.

In the accompanying drawing 1 be axial moving device, 2 for the input worm screw, 3 for flexible rod, 4 for the sound conversion equipment, 5 for casing, 6 for bearing, 7 for rotating shaft, 8 for transfer panel, 9 for the established angle indicating device, 10 for rocking arm type movable vane slewing gear mechanism, 11 for motor, 12 for rocking handle, 13 for limiting block, 14 for pressure spring, 15 for the pad frame.

Embodiment

The utility model comprises the axial moving device 1 with flexible rod 3; Described flexible rod 3 links to each other with sound conversion equipment 4; The described sound conversion equipment 4 of its structure outline comprises the casing 5 that an end is fixed with flexible rod 3, and the rotating shaft 7 that the outside has bearing 6 is set in the casing 5; The end of rotating shaft 7 is stretched out by casing 5 the other ends, and links to each other with transfer panel 8.

Described axial moving device 1 comprises input worm screw 2, and the gear on worm parafacies in the input worm screw 2 coaxial shifters 1 connects, and described flexible rod 3 is the output terminal of worm tooth wheel set.Realize the control that the flexible rod 3 to axial moving device 1 moves axially through input worm screw 2.

Described worm tooth wheel set is a common practise, so not shown.

Described input worm screw 2 links to each other with the output shaft of motor 11, and the end of the output shaft of motor 11 is provided with rocking handle 12; Can be through motor 11 control input worm screws 2, when outage or other situation, can regulate the movable vane of ventilator through the mode that manpower shakes rocking handle 12.

Described input worm screw 2 is provided with established angle indicating device 9; The rotation of the gear train that established angle indicating device 9 links to each other with input worm screw 2 through its inside can show the angle that input worm screw 2 is rotated, and is convenient to the ventilator movable vane is adjusted the control of angle.

Described casing 5 inner two ends are provided with bearing 6, are provided with limiting block 13 corresponding to two bearings 6 in the rotating shaft 7 between the two bearings 6.

For bearing 6 is better worked, the pad frame 15 with pressure spring 14 is set between bearing 6 and the casing 5.

Described casing 5 bottoms are provided with road wheel, are convenient to sound conversion equipment 4 and move axially.

Course of action below in conjunction with description of drawings the utility model: transfer panel 8 is connected with rocking arm type movable vane slewing gear mechanism 10 on being located at the propeller fan rotor disk; The input worm screw 2 of the worm tooth wheel set of axial moving device 1 is extended to outside the fan casing, link to each other with the output shaft of motor 11.The axial-flow blower wheel disc is when the work running, and regulation and control motor 11 turns over the corner of setting, and then rotating shaft 7 straight lines move corresponding distance, makes movable vane turn over corresponding angle, just reaches the purpose of regulating the movable vane established angle.If adopt manpower then directly shake the input worm screw 2 of worm tooth wheel set through rocking handle 12.Because

input worm screw

2 and 9 interlocks of movable vane established angle indicating device just can detect the angle that the movable vane established angle rotates through movable vane established angle indicating device 9 simultaneously.
