Abstract
The utility model relates to a low noise type micro-motor output shaft. The upper part of a metal output core shaft is provided with enveloping plastics by injection moulding on the basis of the metal output core shaft and a plastic gear which is arranged at the middle lower part of the utility model. Accordingly, the utility model is favorably matched with a driven plastic mating member, and the scraping of garbage in the assembling process can be decreased. The utility model has the advantages of low working noise, etc. The utility model is especially adapted for driving a wind shield plate of an air-conditioner, and is also adapted for domestic appliances, such as a dish-washing machine, etc.
Description
Technical field
The utility model relates to a kind of micro motor output shaft, and particularly a kind of output shaft that is used to drive the reciprocating micromachine of air-conditioning barge board belongs to the coupling field.
Background technique
The existing output shaft that is used to drive the reciprocating micromachine of air-conditioning barge board, its output mandrel is metal and makes, because driven counterpart is generally working of plastics, in assembly process, be prone to the phenomenon of scraping plastic part, produce scraping powder rubbish, influence normal using effect, and since be driven part and can not cooperate fully well, the space occurs, produce when particularly starting and impact, be easy to generate noise.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned output shaft, design a kind of can be driven low noise that part better cooperates and that in assembly process, can reduce the rubbish of the swiping motor output shaft that declines.
The low noise of the present utility model motor output shaft that declines mainly is on the basis of existing output shaft, changes the output mandrel of metal into plastics formula output mandrel, specifically is the top injection moulding outsourcing plastics of metal being exported mandrel.In order to prevent outsourcing plastics axial motion, can be provided with locating slot on the top that metal is exported mandrel.For the assembling of being more convenient for, the tip edge of outsourcing plastics can be made as inclined to one side gesture shape or conical surface.
The low noise of the present utility model motor output shaft that declines, owing to change the output mandrel of metal into plastics formula output mandrel, make it to have and better cooperate and in assembly process, also can reduce scraping rubbish with driven plastics counterpart, have advantages such as operating noise is low, be particularly suitable for driving the air-conditioning barge board and use, also be fit to use on the household electric appliance such as dishwasher.
Description of drawings
Accompanying drawing 2 is structural representations of the present utility model;
Accompanying drawing 3 is the cross-sectional structure schematic representation on the top of accompanying drawing 2.
Embodiment
Referring to accompanying drawing, among Fig. 1 and Fig. 21 is plastic gear, the 2nd, metal output mandrel is because the output mandrel top of Fig. 1 directly contact with driven working of plastics with its metal surface, so easily produce big noise and the easy generation shortcomings such as powder rubbish of swiping when assembling.Accompanying drawing 2 is the improvement to accompanying drawing 1, mainly be top injection moulding outsourcing plastics 3 at metal output mandrel 2, because outsourcing plastics 3 have certain thickness, the top of metal being exported mandrel 2 before injection moulding suitably dwindles and gets final product, in order to prevent outsourcing plastics axial motion, can be provided with locating slot 5 on the top that metal is exported mandrel.For the assembling of being more convenient for, the tip edge of outsourcing plastics 3 can be made as inclined to one side gesture shape or conical surface 4.If, then can when load is excessive, protect gear and motor with setting up friction slip mechanism between plastic gear 1 and the output mandrel 2.Have advantages such as operating noise is low, be particularly suitable for driving the air-conditioning barge board and use, also be fit to use on the household electric appliance such as dishwasher.
Claims (3)
1, a kind of low noise motor output shaft that declines comprises metal output mandrel and is installed in the plastic gear of its middle and lower part, it is characterized in that the top injection moulding outsourcing plastics of metal output mandrel.
2, the low noise as claimed in claim 1 motor output shaft that declines is characterized in that the top of metal output mandrel is provided with locating slot.
3, the low noise as claimed in claim 1 or 2 motor output shaft that declines is characterized in that the tip edge of outsourcing plastics is made as inclined to one side gesture shape or conical surface.
