Description
Technical field
The utility model relates to a kind of Industrial fan, specifically is a kind of swinging mechaism of Industrial fan.
Background technique
The relative normal domestic use fan of Industrial fan has that power is big, wind-force is strong, noise is high, volume weight is also bigger simultaneously, family expenses fan swinging mechaism often is not suitable for Industrial fan, therefore existing industrial fan is not provided with swinging mechaism usually, in factory floor, often need to place many Industrial fans summer and reach the purpose that cooling disappears and affixes one's name to, so noise in workshop is bigger, how fan has been placed influences workman's operation in the way, swinging mechaism also is installed for Industrial fan, so just can be improved the Industrial fan utilization efficiency greatly.
The model utility content
The purpose of this utility model is to provide a kind of Industrial fan, and this Industrial fan is provided with the mechanism of waving of head, and swinging mechaism is simple in structure, easy to use, and has stuck protection mechanism.
The utility model is achieved in that
A kind of swinging mechaism of Industrial fan, comprise that main frame reaches the support device that is connected usefulness with host activities, it is characterized in that: be provided with reduction gear box at the main frame rear portion, this reduction gear box is by casing, driving gear, connecting worm screw and output gear shaft forms, the inlet opening that the main shaft afterbody of main frame passes the reduction gear box body is meshed with driving gear, the output gear shaft of reduction gear box passes from the main frame bottom, on the output terminal of output gear shaft, be fixed with a connection piece, have an end off-centre of a driving arm to be connected on the link, the other end of driving arm is movably connected on the support device.
Described subtracting is provided with two cavitys in the casing, driving gear be connected ccontaining one of them cavity of worm screw in, output gear shaft is provided with in another cavity, the gear of output gear shaft is meshed with groove on being connected worm screw, the output terminal of output gear shaft passes from the bottom of reduction gear box, described driving gear connects on the worm screw with being connected the coaxial setting of worm screw and being socketed in, and also is provided with anti-jamming mechanism between connection worm screw and driving gear.
Described anti-jamming mechanism by be arranged on the connection gear annular cover be arranged on the spring and the ball that are connected on the worm screw and form, annular is set on the top of connection gear, is provided with several equally distributed convex tendons in annular is overlapped; Have a through hole on described connection worm screw, spring and ball just are provided with in this through hole, and two balls are in the two ends of spring, and ball is pushed up to the annular cover under the effect of spring.
The utility model drives the connection gear of reduction gear box by the main frame main shaft, connection gear drives by anti-jamming mechanism and connects worm screw, drive the output gear shaft rotation by connecting worm screw, the rotation of output gear shaft makes that the position relation of eccentric tie point and another tie point of driving arm constantly changes on the link, thereby since the length of driving arm constant force to roll with the generation of fan main frame guarantee that two distances between the tie point are constant, connection gear be connected anti-sticking gear mechanism between the worm screw when the gear generation stuck phenomenon, the connection gear rotation can not drive when connecting the worm screw rotation, force with the ball pressure and tie the spring that contracts, use connection gear and connect between the worm screw and skid, thus the normal operation of assurance main motor.
