Abstract
The utility model relates to a motor output shaft which comprises a plastic output shaft, a plastic gear and a metal central spindle which are integrated, wherein the upper part of the metal central spindle is coated with the plastic gear in an injection molding manner; the metal central spindle is perpendicular to a tooth side surface of the plastic gear; and the upper part of the plastic gear and the plastic output shaft are connected into a whole. The motor output shaft gets rid of the original riveting pressing structure, and adopts an output shaft and gear integrated injection molding structure; in order to ensure the matching of the output shaft and a gear plate, contact end parts of the output shaft and the gear plate are connected by the metal central spindle, so that the output shaft operates more stably; a hole in the middle of the plastic output shaft can effectively reduce shrinkage generated by the output shaft in an injection molding process, so that the size of the integrated output shaft is more stable; and the output shaft with the structure can save the production cost, reduces noise, is wear-proof and simple in structure, and is suitable for use.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of motor output shaft.
Background technique
The output shaft ordinary circumstance that the now stepping on market, synchronous machine use is metal material, by riveted joint, realizes coordinating of output shaft and gear, and processing mode is more loaded down with trivial details, and cost is also higher.
The model utility content
The technical problems to be solved in the utility model is: in order to solve output shaft, to adopt metal material and gear riveted joint to process loaded down with trivial details, the problem that cost is higher, and the utility model provides a kind of motor output shaft to solve the problems referred to above.
The utility model solves the technological scheme that its technical problem adopts: a kind of motor output shaft, the plastic output axis, plastic gear and the metal core axle that comprise one, described plastic gear injection moulding is coated on the top of metal core axle, metal core axle is vertical with the flank of plastic gear, and top and the plastic output axis of described plastic gear are connected as a single entity.Adopt the output shaft of plastics to replace original metal output shaft, in order to increase the wear resistance of plastic output axis and gear plate, the end that plastic output axis contacts with gear plate is provided with metal core axle.
In order to make the plastic output axis structure more stable, be provided with the hole that prevents injection moulding contracting shape in described plastic output axis, the center line in described hole overlaps with the center line of metal core axle.
The beneficial effects of the utility model are, the utility model motor output shaft, break away from original rivet pressing structure, adopt output shaft, gear integral type injection structure, and in order to guarantee coordinating of output shaft and gear plate, output shaft adopts metal core axle to be connected with the end of gear plate contact, make the output shaft operation more stable, hole in the middle of plastic output axis can effectively reduce the miniature that output shaft produces in injection moulding process, make the size of integral type output shaft more stable, the output shaft of this structure, can save cost of production, reduce noise, and wear-resisting, simple in structure, be suitable for using.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the optimum embodiment's of the utility model motor output shaft structural representation.
In figure 1, plastic output axis, 2, plastic gear, 3, metal core axle, 4, hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model motor output shaft, the plastic output axis 1, plastic gear 2 and the metal core axle 3 that comprise one, plastic gear 2 injection mouldings are coated on the top of metal core axle 3, metal core axle 3 is vertical with the flank of plastic gear 2, the top of plastic gear 2 and plastic output axis 1 are connected as a single entity, and are provided with the hole 4 that prevents injection moulding contracting shape in plastic output axis 1, and the center line in hole 4 overlaps with the center line of metal core axle 3.
This integral type output shaft can be widely used on the motor in fields such as driving air-conditioning barge board, fireplace, stage lamp, projector, medical apparatus, laser lamp, supervisory system and cleaners and polishes.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to the claim scope.
