Abstract
A high strength plastic gear type micro-motor output shaft mainly comprising a metal output shaft 4, a plastic gear 5 and a plastic locating shaft 6, the plastic gear 5 is wrapped under the middle of the metal output shaft 4 with injection moulding, the lower part of the plastic gear 5 is integrated with the plastic locating shaft 6, and the cast gate for injection moulding is arranged on the end of the plastic locating shaft 6. When injection moulding, the molten plastic is entered from the plastic locating shaft end, the temperature distribution will be even, the distribution of stress will also be uniform, and the axial fusion jointing marks will still less come into being, thereby the strength of the plastic gear will be strengthened effectively. Being provided with the advantages of no-crack, more stable performance and long service life etc, and also being provided with friction-skidding performance, which is favorable to protect the motor in overloading, the utput shaft more particularly adequate for the micro-motor driven the wind screen of air conditioning, also adequate for the micro-motor used for the household electrical appliance of dishwasher 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 micro motor of air-conditioning barge board, the mandrel of its output shaft is metal and makes, plastic gear is injection-moulded in the middle part of output shaft, its injection hole is opened the side at plastic gear, can be in injection moulding process at the outside journal axle of plastic gear to being formed with weld mark, during work, ftracture and reduction of service life at weld easily.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned output shaft, designs highstrenghtpiston's gear type micro motor output shaft of a kind of rational in infrastructure, stable performance and long service life.
Highstrenghtpiston's gear type micro motor output shaft of the present utility model mainly is made up of metal output shaft and plastic gear and plastics positioning shaft, and described plastic gear injection moulding is wrapped in the bottom of metal output shaft, and the bottom of plastic gear and plastics positioning shaft are connected as a single entity.This structure is convenient to the injection moulding sprue gate is opened on the center line of plastics positioning shaft end, can increase the operating life of output shaft.
The micro motor output shaft that has highstrenghtpiston's gear of the present utility model because the method for employing center cast, so just avoided formation along the outside journal axle of plastic gear to weld mark, increased the intensity of plastics.Have and do not ftracture, the advantage of stable performance, long service life etc. also possesses the friction performance of skidding, and helps protecting motor when overload, and the micro motor that is particularly suitable for driving the air-conditioning barge board uses, and the micro motor that also is fit on the household electric appliance such as dishwasher uses.
Description of drawings
Accompanying drawing 1 is the structural representation of existing output shaft;
Accompanying drawing 2 is structural representations of the utility model output shaft.
Embodiment
Referring to accompanying drawing, 1 among Fig. 1 is the metal output shaft, the 2nd, and plastic gear, the 3rd, metal positioning shaft.Because the plastic gear 2 among Fig. 1 is injection-moulded in the middle part of metal mandrel 1, during injection moulding, the sprue gate can only be arranged on the side of plastic gear 2, can form axial weld mark on the one side away from the sprue gate; The intensity at weld mark place is very poor, is easy to generate defectives such as cracking, has a strong impact on working life.Accompanying drawing 2 is output shafts of the present utility model, and 4 among the figure is metal output shafts, the 5th, and plastic gear, the 6th, plastics positioning shaft.Mainly be that output shaft 4 among Fig. 2 is shortened in the bottom of the metal output shaft 1 in the accompanying drawing 1 together with metal positioning shaft 3 removes, plastic gear 5 injection mouldings are wrapped in the Lower Half of metal output shaft 4, and in injection mould, pour into plastics positioning shaft 6 simultaneously, sprue gate when the end of plastics positioning shaft 6 is injection moulding, during injection moulding, liquation enters from plastics positioning shaft 6 lower ends, uniformity of temperature profile, stress distribution is also even, more can not produce axial weld mark recited above, effectively increase the intensity of plastic gear.Have and do not ftracture, advantages such as the more stable and long service life of performance also possessing the friction performance of skidding, and help protecting motor when overload, and the micro motor that is particularly suitable for driving the air-conditioning barge board uses, and the micro motor that also is fit on the household electric appliance such as dishwasher uses.
Claims (2)
1, a kind of highstrenghtpiston's gear type micro motor output shaft, it is characterized in that forming by metal output shaft, plastic gear and plastics positioning shaft, described plastic gear injection moulding is wrapped in the bottom of metal output shaft, and the bottom of plastic gear and plastics positioning shaft are connected as a single entity.
2, highstrenghtpiston's gear type micro motor output shaft as claimed in claim 1, the sprue gate the when end that it is characterized in that the plastics positioning shaft is injection moulding.
