Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Before the utility model is described in detail, be noted that in following description similar elements is to represent with identical numbering.
Consult Fig. 2, Fig. 3 and Fig. 4; First preferred embodiment for the radiation fan of the utility model autobalance counterweight; Comprise a rotating shaft 2, be incorporated into this rotating shaft 2 an end and can interlock the impeller unit 3 of these rotating shaft 2 rotations, and the counterweight element 4 that is connected with this rotating shaft 2.
This rotating shaft 2 is formed with a containing groove 22.This counterweight element 4 comprises that one is fixedly set in the carrier 41 of the containing groove 22 of this rotating shaft 2, and several are arranged at the counterweight member 42 in this carrier 41, and this carrier 41 has the interior surrounding wall that contact with the containing groove 22 of this rotating shaft 2 411, one and this interior surrounding wall 411 outer surrounding wall 412 separately; And two connect surrounding wall 411 in this, outer surrounding wall 412 connecting wall 413 with side respectively; Surrounding wall 411, outer surrounding wall 412, connecting wall 413 match and center on a guide slot 400 around this rotating shaft 2 in being somebody's turn to do, and in the present embodiment, the aspect that said counterweight member 42 is balls also is arranged in the guide slot 400 slippingly; Be that said counterweight member 42 can receive the influence of centrifugal force and rolling in this guide slot 400; And this carrier 41 is to be C type disk body shape, can be apace is interlocked fixingly with the containing groove 22 of this rotating shaft 2, but also can be annular; Containing groove 22 with sheathed mode and this rotating shaft 2 fastens; In addition, in the present embodiment, wherein a connecting wall 413 is to be fixedly arranged on separatably on this interior surrounding wall 411, the outer surrounding wall 412; When this connecting wall 413 breaks away from, can supply said counterweight member 42 to set in this guide slot 400.
Consult Fig. 3; When this impeller unit 3 began to drive this rotating shaft 2 and 41 rotations of this carrier, unbalanced weight when this impeller unit 3 rotates made the counterweight member 42 of this counterweight element 4 can receive uneven centrifugal forces affect; At this moment; Said counterweight member 42 can roll along guide slot 400 position that 3 weight are lighter towards the impeller unit of this carrier 41, just can supply unbalanced weight simultaneously, reaches the effect of autobalance counterweight immediately; This impeller unit 3 is rotated has good balance, so this impeller unit 3 need not carry out extra counterweight operation.
Consult Fig. 5, for second preferred embodiment of the radiation fan of the utility model autobalance counterweight, roughly the same with first preferred embodiment; Different places are that this outer surrounding wall 412 has a breach 414, and this guide slot 400 is connected with the external world; This guide slot 400 another kind of different enforcement aspects are provided; With this first preferred embodiment identical effect is arranged, on making, can reduce the use of former material simultaneously, reduce cost.
Consult Fig. 6; Be the 3rd preferred embodiment of the radiation fan of the utility model autobalance counterweight, roughly the same with first preferred embodiment, different places are: this carrier 41 is to be arranged at rotationally in this rotating shaft 2; And this counterweight member 42 is to be fixedly arranged in this carrier 41; And the weight that makes this counterweight element 4 is to lay particular stress on this counterweight member 42, so when this impeller unit 3 began to drive this rotating shaft 2 and rotates with this carrier 41, unbalanced centrifugal force can make this carrier 41 rotate relative to this rotating shaft 2; And then drive this counterweight member 42 and relatively move to lighter position, impeller unit 3; Replenish the rotary balance underweight, the effect that reaches the autobalance counterweight arranged equally, so this impeller unit 3 is rotated can balance.In the present embodiment, the quantity of counterweight member only is provided with one.But when reality is implemented, most counterweight members can be set also,, all can reach the purpose of the utility model as long as make it lay particular stress on a side at carrier.
In sum; The radiation fan of the utility model autobalance counterweight; In this impeller unit 3 can adjust this impeller unit 3 when rotating automatically through the counterweight member 42 of this counterweight element 4 counterweight; Therefore can there be good balance this impeller unit 3 when rotating, so do not need each fan to carry out the counterweight operation respectively, saves activity duration and manpower.
