Abstract
The utility model discloses a joint bearing adjusting door. The joint bearing adjusting door comprises an air cylinder, a conical body, a tie bar, blades and adjustment control mechanisms, wherein the conical body is positioned in the center of the air cylinder; one end of the tie bar is connected with the conical body; the other end of the tie bar is connected with the inner wall surface of the air cylinder; the blades are circumferentially arranged in the air cylinder; a joint at the bottom ends of the blades is positioned in a pin shaft hole in the conical body; a rotating shaft at the other ends of the blades is supported by a bearing base and a bearing connecting base which are arranged on the outer diameter of the air cylinder; the adjustment control mechanisms are connected with the blades in a driving way and comprise driving forks, joint bearings and connecting rods; two adjacent driving forks are connected by a connecting rod of which the two ends are provided with the joint bearings; and one driving fork is connected with an electric actuator through the connecting rod of which the two ends are provided with the joint bearings. The joint bearing adjusting door has the advantages of flexible rotation, convenience in operation, no noise caused by vibration and the like and is applied to a fan regulation device, such as a petal adjusting door.
Description
Technical field
The utility model relates to a kind of joint shaft bearing adjustment doors.
Background technique
The Fan Regulation door is for the device of regulating fan delivery.Wherein, the petal type adjustment doors is made up of a plurality of rotatable blades, and a plurality of blades are evenly distributed in the air intake tube along circumference, and the angle of swing of control blade can realize the adjusting of fan delivery.At present, the petal type adjustment doors adopts turning collar to drive the adjusting control mechanism of rotatingshaft and shift fork, and there is following defective in this structure:
Turning collar drives rotatingshaft and drives the shift fork rotation when 1, regulating, and drives blade rotation by shift fork again, and component are many, power consumption is big, and working life is low;
2, have big gap between sliding-groove and the rotating shaft, this gap in use because wearing and tearing continue to increase, adds the gap of other moving elements, causes the transmission integrating error big, and precision is low;
3, turning collar can only along the circumferential direction rotate, and the chute rubbing contact of rotatingshaft and shift fork has increased rotational resistance during rotation, rotates dumb;
4, the transmission part integrating error are big, and there be bigger freely swinging in each blade, and blade vibrates bigger under the impact of wind, and noise is bigger.
In sum, this structure adjustment doors inconvenient operation is rotated dumbly, and it is controlled poor to regulate, and uses noise big, and functional reliability is poor, needs to improve its usability, demands urgently improving.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to propose a kind of joint shaft bearing adjustment doors, by enforcement of the present utility model, regulates and rotates flexibly, and drive gap is little, reliable operation, and noise is low.
For reaching this purpose, the utility model by the following technical solutions:
A kind of joint shaft bearing adjustment doors comprises:
Air duct;
Cone is positioned at the air duct center;
Lacing wire, an end of described lacing wire is connected with described cone, and the other end is connected with the internal face of described air duct;
Blade is circumferential arrangement in described air duct, and the joint of blade bottom end is positioned at described cone upper pin hole, and the rotating shaft of the blade the other end is supported by the supporting base and the bearing seated that are installed on the air duct external diameter;
Adjusting control mechanism with each blade is in transmission connection comprises:
Transmission fork, joint shaft bearing and connecting rod, two adjacent transmission forks are connected by the connecting rod of two ends band joint shaft bearing; One of them transmission fork is connected with electric actuator by the connecting rod of two ends band joint shaft bearing.
Preferably, described cone comprises interconnective upper cone and lower cone.
Preferably, described rotating shaft one end is connected with vanes fixed, and the other end is connected with transmission fork.
Preferably, two adjacent transmission forks are connected by the connecting rod of two ends band joint shaft bearing in the described adjusting control mechanism; One of them transmission fork is connected with electric actuator by the connecting rod of two ends band joint shaft bearing.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model, have advantages such as rotation is flexible, easy to operate, the shockproof noise of blade, suit to use at Fan Regulation devices such as petal type adjustment doors.
