Abstract
A heat sink for a variable frequency motor provided by the invention comprises a radiating impeller. A disc-shaped pedestal is fixed at the center of the radiating impeller, and an intermediate gear is fixed on the disc-shaped pedestal; a through hole is arranged at the center of the intermediate gear and is divided in two sections, one section is a motor shaft containing section, and the other section is an internal spline section; and the diameter of the motor shaft containing section is larger than the diameter of the internal spline section, a step portion is formed at the combination position of the motor shaft containing section and the internal spline section, and grooves are arranged at the connection position of the motor shaft containing section and the internal spline section. Because the grooves are arranged at the connection position of the motor shaft containing section and the internal spline section, the root of the motor shaft and the intermediate gear cannot be worn by friction.
Description
Technical field
The present invention relates to a kind of heat abstractor for variable-frequency motor, belong to washing machine appurtenances technical field.
Background technology
Roller washing machine variable-frequency motor can generate heat in a large number in running, and too much heat is unfavorable for variable-frequency motor running.Internal machine volume is limited simultaneously, has strict demand for heat abstractor volume.For coordinating the installation of roller washing machine variable-frequency motor heat abstractor, need to design a kind of jockey.Publication number is CN202867594U, name is called that the utility model patent of " a kind of idler gear for connecting variable-frequency motor heat abstractor " discloses a kind of technical scheme: idler gear is connected to heat-dissipating impeller center by intermediate connector, described idler gear is cylinder, it is internal spline inside described idler gear, one end is provided with discoidal base, and described chassis outer side is external splines.The defect that idler gear exists is: when motor shaft is fitted within idler gear, the root of motor shaft and idler gear can cause wearing and tearing because of friction.
Summary of the invention
The object of the invention is to provide a kind of heat abstractor for variable-frequency motor.
For achieving the above object, the technical solution used in the present invention is: a kind of heat abstractor for variable-frequency motor, comprises a heat-dissipating impeller, and the center of this heat-dissipating impeller is fixed with disc-shaped base, this disc-shaped base is fixed an idler gear; The center of described idler gear offers a through hole, and this through hole is divided into two sections, and one section is motor shaft accommodating section, and another section is internal spline section; The diameter of described motor shaft accommodating section is greater than described internal spline section, and both junctions form stage portion, and described motor shaft accommodating section is provided with groove in the junction with internal spline section.
Preferred technical scheme is: the material of described disc-shaped base is high molecule plastic.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
The present invention is owing to being provided with groove in motor shaft accommodating section in the junction with internal spline section, and the root of motor shaft and idler gear can not cause wearing and tearing because of friction.
Accompanying drawing explanation
Accompanying drawing 1 is idler gear cross-sectional schematic.
Accompanying drawing 2 is heat abstractor schematic diagram.
In above accompanying drawing, 1, idler gear; 2, motor shaft accommodating section; 3, internal spline section; 4, groove; 5, heat-dissipating impeller; 6, disc-shaped base.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, still all should drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
Embodiment: for the heat abstractor of variable-frequency motor
Shown in accompanying drawing 1 and accompanying drawing 2, for the heat abstractor of variable-frequency motor, comprise a heat-dissipating impeller 5, the center of this heat-dissipating impeller 5 is fixed with disc-shaped base 6, this disc-shaped base 6 is fixed an idler gear 1; The center of described idler gear 1 offers a through hole, and this through hole is divided into two sections, and one section is motor shaft accommodating section 2, and another section is internal spline section 3; The diameter of described motor shaft accommodating section 2 is greater than described internal spline section 3, and both junctions form stage portion, and described motor shaft accommodating section 2 is provided with groove 4 in the junction with internal spline section 3.Owing to being provided with groove 4 in motor shaft accommodating section in the junction with internal spline section, when motor shaft and idler gear 1 assemble, the root of motor shaft and idler gear can not cause wearing and tearing because of friction.The material of described disc-shaped base 6 is high molecule plastic.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (2)
1. for a heat abstractor for variable-frequency motor, it is characterized in that: comprise a heat-dissipating impeller, the center of this heat-dissipating impeller is fixed with disc-shaped base, this disc-shaped base is fixed an idler gear; The center of described idler gear offers a through hole, and this through hole is divided into two sections, and one section is motor shaft accommodating section, and another section is internal spline section; The diameter of described motor shaft accommodating section is greater than described internal spline section, and both junctions form stage portion, and described motor shaft accommodating section is provided with groove in the junction with internal spline section.
