Abstract

The utility model relates to a fan oscillating device comprising a synchronous motor and an oscillating connection rod. One end of the oscillating connection rod is connected with a fan head. A drive small gear is arranged on an output shaft of the synchronous motor, a driven large gear is arranged beside the drive small gear, and gear teeth of the drive small gear are meshed with gear teeth of the driven large gear. An oscillating main shaft with the larger diameter is arranged in a center shaft hole of the driven large gear and fixed in a shaft hole of an eccentric wheel. The other end of the oscillating connection rod is fixed to the eccentric wheel. The synchronous motor of the fan oscillating device can drive a larger and heavier fan head, and the service life of the fan oscillating device can be prolonged effectively.

Description

A kind of fan head-shaking device
Technical field
The utility model relates to fan, is specifically related to a kind of head-shaking device of fan.
Background technique
Existing head-shaking mechanism of electric fan, generally all be provided with a synchronous machine and a connecting rod, one end of connecting rod is connected with the output shaft of synchronous machine, and the other end is connected with the head of fan, by the direct drive link of synchronous machine, rotated, then shaken the head by certain amplitude by connecting rod drive fan head.The defect that the fan head-shaking device of this structure exists is: if strengthen size and the weight of fan head, original synchronous machine cannot drive head to swing, and need to change more powerful synchronous machine; And during due to the work of this head-shaking device, by the output shaft of synchronous machine, directly promoting link motion, synchronous machine body itself will directly bear push-pull effort, easily causes shorten the working life of synchronous machine.
Model utility content
The synchronous machine drives that the purpose of this utility model is to provide a kind of available same power more greatly, the fan head-shaking device of heavier fan head, meanwhile, this head-shaking device also can extend the working life of synchronous machine.
The technical solution of the utility model is as follows:
, comprising a synchronous machine and a yaw connecting rod, one end of described yaw connecting rod is connected with fan head; The output shaft of described synchronous machine is provided with a driver pinion, and the side of described driver pinion is provided with a driven gearwheel, and the gear teeth of described driver pinion and driven gearwheel are intermeshing; In the central shaft hole of described driven gearwheel, be provided with the yaw main shaft that a diameter is larger, described yaw main shaft is fixed in an eccentric axis hole; The other end of described yaw connecting rod fixes on described eccentric wheel.
Compared to fan head-shaking device before, the utility model is provided with one group of gear mechanism consisting of a driver pinion, a driven gearwheel, a yaw main shaft and an eccentric wheel between synchronous machine and yaw connecting rod, the moment of exporting during synchronous machine work can be amplified via this gear mechanism, even if therefore the synchronous machine of same power is applied on the fan that flabellum and head are larger, this synchronous machine is the fan head of drive fan swing smoothly also, thereby makes the larger fan head of synchronous machine drives of same power.In addition,, when the yaw main shaft of this oscillating head mechanism drives yaw connecting rod, stressed by yaw main shaft, the output shaft of synchronous machine does not bear push-pull effort, thereby can effectively extend the synchronous machine life-span.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's general structure schematic diagram
Fig. 2 is the utility model embodiment's mounting point schematic diagram
In figure, be labeled as: 1, synchronous machine, 2, yaw connecting rod, 3, driver pinion, 4, driven gearwheel, 5, yaw main shaft, 6, eccentric wheel, 7, fan head.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described.
With reference to Fig. 1:
, comprising a synchronous machine 1 and a yaw connecting rod 2, one end of described yaw connecting rod 2 is connected with fan head 7; The output shaft of described synchronous machine 1 is provided with a driver pinion 3, and the side of described driver pinion 3 is provided with a driven gearwheel 4, and the gear teeth of described driver pinion and driven gearwheel 3,4 are intermeshing; In the central shaft hole of described driven gearwheel 4, be provided with the yaw main shaft 5 that a diameter is larger, described yaw main shaft 5 is fixed in the axis hole of an eccentric wheel 6; The other end of described yaw connecting rod 2 fixes on described eccentric wheel 6.
The working principle of the present embodiment is: synchronous machine 1 drives driver pinion 3 to rotate, and driver pinion 3 drives driven gearwheel 4 to rotate, and the moment that synchronous machine 1 is exported is amplified in this process; Driven gearwheel 4 drives yaw main shaft 5 to rotate along driver pinion 3,5 band movable eccentric wheel 6 motions of yaw main shaft, and eccentric wheel 6 drives yaw connecting rod 2 by the swing amplitude of setting, and yaw connecting rod 2 drive fan heads 3 swing.
Above-described embodiment is only representative utilization of the present utility model, can also have according to different forms other utilization form.But as long as adopt the fan head-shaking device of said structure, principle and working morphology all to belong to protection domain of the present utility model.
