Abstract
A intermediate gear for connecting inverter motor heat abstractor, a through -hole has been seted up at intermediate gear's center, and this through -hole divide into two sections, and one section is the motor shaft section of holding, and another section is the internal spline section, the diameter of the motor shaft section of holding is greater than internal spline section, combination department between them constitute step portion, just the junction that the motor shaft holds duan zaiyu internal spline section is equipped with the recess. The utility model discloses be equipped with the recess owing to hold the junction of duan zaiyu internal spline section at the motor shaft, the root and the intermediate gear of motor shaft can not lead to the fact wearing and tearing because of the friction.
Description
Technical field
The utility model relates to a kind of intermediate gear for connecting variable-frequency motor sink, belongs to washing machine appurtenances technical field.
Background technique
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 sink volume.For coordinating the installation of roller washing machine variable-frequency motor sink, need to design a kind of connection set.Publication number is CN202867594U, name is called that the utility model patent of " a kind of intermediate gear for connecting variable-frequency motor sink " discloses a kind of technological scheme: intermediate gear is connected to heat-dissipating impeller center by intermediate connector, described intermediate gear is cylindrical body, it is internal spline inside described intermediate gear, one end is provided with discoidal base, and described chassis outer side is external splines.The defect that intermediate gear exists is: when motor shaft is fitted within intermediate gear, the root of motor shaft and intermediate gear can cause wearing and tearing because of friction.
Summary of the invention
The utility model provides a kind of intermediate gear for connecting variable-frequency motor sink.
For achieving the above object, the technical solution adopted in the utility model is: a kind of intermediate gear for connecting variable-frequency motor sink, and the center of described intermediate gear offers a through hole, and this through hole is divided into two sections, 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 stepped part, and described motor shaft accommodating section is provided with groove in the joint with internal spline section.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is owing to being provided with groove in motor shaft accommodating section in the joint with internal spline section, and the root of motor shaft and intermediate gear can not cause wearing and tearing because of friction.
Accompanying drawing explanation
Accompanying drawing 1 is intermediate gear cross-sectional schematic.
In above accompanying drawing, 1, intermediate gear; 2, motor shaft accommodating section; 3, internal spline section; 4, groove.
Embodiment
Below in conjunction with drawings and Examples, the utility model is 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 utility model, 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 utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses 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 utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Embodiment: for connecting the intermediate gear of variable-frequency motor sink
Shown in accompanying drawing 1, for connecting the intermediate gear 1 of variable-frequency motor sink, the center of described intermediate 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 stepped part, and described motor shaft accommodating section 2 is provided with groove 4 in the joint with internal spline section 3.Owing to being provided with groove 4 in motor shaft accommodating section in the joint with internal spline section, when motor shaft and intermediate gear 1 assemble, the root of motor shaft and intermediate gear can not cause wearing and tearing because of friction.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
