Description
Technical field
The utility model is related to living electric apparatus technical fields, and in particular to one kind is rotatably assorted component and fan.
Background technology
Tower is fanned because of its unique pillar moulding, keeps its required floor space when placing smaller, and then increasingly disappeared
The favor of the person of expense, currently, the casing internal of many tower fans has the function of the shaking device being arranged to realize swing flap, yaw dress
It sets and realizes swing flap by driving wind wheel to swing, but also just since tower fan fuselage is longer, chassis floor space and relatively small column
Formula moulding reduces the chassis stability of tower fan, and shaking device is set to the bottom of tower fan, and driving force needs to conduct to tower to fan to push up
End could drive wind wheel to swing, therefore tower fan, in yaw, the swing of shaking device is unstable to easily lead to tower fan fuselage production
It is raw to shake.
Usually, shaking device includes the fixed seat being fixedly connected with casing, and being set to being capable of phase above fixed seat
For the rotation seat of fixed seat rotation, the driving motor of wind wheel and driving wind wheel rotation outlet air is fixedly installed on rotation seat, is turned
Rotating mechanism is additionally provided in dynamic seat, rotating mechanism drives rotation seat relative to fixed seat reciprocally swinging, then so that wind wheel phase
For casing reciprocally swinging, swing flap is realized.In order to improve the swing stability of shaking device fuselage is fanned further to improve tower
Shaking problem, the prior art is used is arranged cone match between rotation seat and fixed seat, rotation seat and shape at fixed seat cooperation
At mutually chimeric taper surface, by increasing the cooperation area between rotation seat and fixed seat, the fit clearance for reducing the two carries
High fitment stability, but cone match manufacturing cost is high, and scale error control is stringent, accordingly improves production, assembly cost；For
This present inventor proposes the rolling elements such as setting ball, roller between rotation seat and fixed seat in R＆D process,
Washer of the fixed setting with lower raceway, raceway in the annular opposite with lower raceway is formed in rotation seat bottom in fixed seat,
The technical solution that the two is rotatably assorted is realized by the rolling cooperation of rolling element and raceway, without manufacturing taper fit face, you can
Make the smooth stabilization that is rotatably assorted between rotation seat and fixed seat, is aligned for the ease of the installation of upper and lower raceway, lower raceway is also set
It is set to annular.But it has been found that due to being influenced by mismachining tolerance in R＆D process, the upper raceway on rotation seat is under
Raceway size, position cannot correspond to completely so that when raceway is installed under the alignment of the above raceway, be easy to cause rotation seat peace
Dress shifts, and ball is caused to wear, and the cooperation center of gravity of rotation seat and rolling element shifts, and generates shaking, and then affect
The shaking device even stability of tower fan fuselage.
Utility model content
Therefore, the technical problem to be solved by the present invention is to overcome the assembly of rotation seat in the prior art and fixed seat
Be easy by process, rigging error is influenced, both lead to the defect that stability is poor, is also easy to produce shaking that is rotatably assorted, to offer one
Kind cooperation is more steady, is not susceptible to the component that is rotatably assorted shaken.
Further provide for a kind of fan with the above-mentioned component that is rotatably assorted.
