Description
Technical field
The present invention relates to a kind of air conditioner structure, especially a kind of air conditioner motor electric fan positioning means.
Background technique
Usually, air conditioner is arranged on any interior space or wall of office or family, and the equipment of conduct heating or cool room air.Air conditioner comprises compressor, condenser, expansion valve and vaporizer, has constituted refrigeration cycle thus.In this case, compressor, condenser, expansion valve and vaporizer sequentially connect.
Specifically, this air conditioner comprises and is arranged in outdoor outdoor unit (being outdoor or the thermal radiation end) and is arranged in indoor indoor unit (being indoor or heat absorbing end).This outdoor unit comprises condenser (being outdoor heat exchanger) and compressor.This indoor unit comprises vaporizer (being indoor heat exchanger).
Known in the artly be that air conditioner is divided into wherein indoor unit and outdoor unit detachable air conditioner mounted separately from each other usually and wherein indoor unit and outdoor unit are integrated in a package AC plant in the unit.
No matter be indoor unit or outdoor unit for detachable air conditioner; All be to rely on the rotation of driven by motor fan to produce air quantity; Wherein just need motor shaft and fan be fixed together; Its method that adopts is the cylinder that tumbles in a hollow at the end face of fan, with a screw cylinder is fixed on the motor shaft again.Though this fixation method has played fixing effect, assembling but is difficulty very, at first need motor shaft be inserted in the cylinder of hollow, and the screw of aiming on the hollow circuit cylinder with screw is again tightened.Because this operation is accomplished in fan inside, accidentally screw will fall into motor shaft inside, seeks very inconvenience, so brought great difficulty and inconvenience to assembly working, has influenced manufacturing efficiency.
To above-mentioned defective, a kind of improvement of making in the existing technology is as shown in Figure 1, wherein is fixed with motor shaft 102 on the rotor of motor 101, and this motor shaft 102 can insert in the wheel hub groove of fan, fan is fixed or fixed with other modes through locknut.Motor shaft 102 outer ends form the plane 103 of certain-length, and these plane 103 inboard certain distances are provided with annular stop fixture block 104 to limit the position that motor shaft 102 inserts fan.
Yet this air conditioner motor electric fan structure of the prior art because the length of fan is different, causes the motor of the different position lengths of needs exploitation to solve production line assembling problem, and then causes motor type various, increases management and cost of developing.
Summary of the invention
The technical problem that the present invention will solve provides a kind of location of motor and fan that can make and realizes adjustable motor ventilating fan positioning means, thereby avoids because of the different defectives of having to develop new motor of fan length.
For addressing the above problem, the motor ventilating fan positioning means among the present invention comprises motor shaft and axle sleeve, and said motor shaft is installed on the rotor of motor, and this motor shaft is provided with the pin of a convexity, and axle sleeve is enclosed within on the motor shaft; Said axle sleeve is cylindric, and its internal diameter equates that with the motor shaft external diameter this cylindric axle sleeve is provided with an axially open vertically, and the middle part of axially open is evenly distributed with a plurality of radial openings, and said radial opening end has one to extend axially to motor shaft outer end direction.
The width of said axially open and radial opening is slightly larger than cotter width.
The pin and the motor shaft of said motor shaft raising are one-body molded.
Said axle sleeve is that the fine nylon material of carbon is processed.
The manufacturing that is formed in one of said axle sleeve.
Radial opening on the said axle sleeve is two.
Adopt motor ventilating fan positioning means of the present invention; In use at first axle sleeve is inserted in from the outer end of motor shaft; Make in the axially open of pin on axle sleeve on the motor shaft and to move, arrive the radial opening place until pin, rotary axle box makes pin get into the inner end of radial opening until radial opening; Direction continues to move axle sleeve in motor shaft then, and pin is got in the extending axially of radial opening end.As required the fan of suitable length is carried out fitting operation then.When the fan that needs different length is installed, only need pin be placed in the into different radial openings according to above-mentioned steps and just can realize.Pin moves freely in axially open and radial opening for ease, and the width of said axially open and radial opening can be slightly larger than cotter width.Pin can be one-body molded with motor shaft, thereby avoid because of it is fixed in the hole on the motor shaft motor shaft being damaged.Said axle sleeve is that the fine nylon material of carbon is processed, and the fine nylon material of carbon has high-intensity characteristics, can avoid axle sleeve wearing and tearing in use.Said axle sleeve can be made in the one cast molding, the convenient manufacturing.Consider that the radial opening on the axle sleeve too much can have influence on the intensity of axle sleeve, therefore the radial opening on the said axle sleeve is preferably two.The motor ventilating fan positioning means of structure of the present invention, simple in structure, the convenient making solves huge technical problem with minimum cost, practices thrift a large amount of cost of production and management development cost, improves the performance of enterprises.
