Abstract
The utility model discloses an intermediate gear for being connected with a radiating device of a variable frequency motor. The intermediate gear is a cylinder, is connected to the center of a radiating impeller through an intermediate connector, and adopts an internal spline on the inner side; a disc-shaped base is arranged at one end of the intermediate gear; and an external spline is arranged on the outer side of the base. The connecting device can effectively connect a output shaft of a motor with the impeller; the inner side of the gear adopts the spline design, therefore the output shaft of the motor can be matched to prevent relative rolling, the contract area is large, and the reliability is high; and the intermediate gear is simple in structure and convenient to produce massively.
Description
Technical field
The utility model relates to a kind of connection set, in particular to a kind of intermediate gear for connecting roller washing machine variable-frequency motor sink.
Background technique
The roller washing machine variable-frequency motor can generate heat in running in a large number, and too much heat is unfavorable for the variable-frequency motor running.The washing machine internal limited space has strict demand for the sink volume simultaneously.For cooperating the installation of roller washing machine variable-frequency motor sink, need a kind of connection set of design.
The model utility content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of intermediate gear for connecting the variable-frequency motor sink is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of intermediate gear for connecting the variable-frequency motor sink, described intermediate gear is connected in the heat-dissipating impeller center by intermediate connector, and described intermediate gear is cylindrical body, and described intermediate gear inboard is internal spline, one end is provided with discoidal base, and described chassis outer side is external splines.
Preferably, described internal spline is involute splines.
Preferably, described external splines is rectangular spline.
The beneficial effects of the utility model are:
This connection set can effectively be connected motor output shaft with impeller, gear is inboard can to cooperate motor output shaft to prevent relative rolling for spline designs, and surface of contact is large, and reliability is high; The utility model is simple in structure, is convenient to batch production.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 the utility model annexation schematic representation;
Fig. 2 the utility model overall structure schematic representation.
Number in the figure explanation: 1, intermediate gear, 101, internal spline, 102, base, 103, external splines, 2, intermediate connector, 3, heat-dissipating impeller.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to Fig. 1, shown in Figure 2, a kind of intermediate gear for connecting the variable-frequency motor sink, described intermediate gear 1 is connected in heat-dissipating impeller 3 centers by intermediate connector 2, described intermediate gear 1 is cylindrical body, described intermediate gear 1 inboard is internal spline 101, one end is provided with discoidal base 102, and described chassis outer side is external splines 103.
Preferably, described internal spline 101 is involute splines.
Preferably, described external splines 103 is rectangular spline.
Intermediate gear is put into above the injection mould, heat-dissipating impeller is placed on above the injection mould, it is plastic injection-moulded between intermediate gear and heat-dissipating impeller that injection machine carries out injection moulding PBT material, make intermediate gear, intermediate connector, heat-dissipating impeller be combined together to form rotor, injection-moulded plastic has nine stiffening ribs, the weight of design centre gear increases gravity, and the concentric requirement of product can be guaranteed.The effect of the intermediate connector of outer ring is fixing in addition and the function of link gear, and guaranteed too the rotating shaft of gear driven washing machine the inside is rotated with one heart, and surface of contact is large, and reliability is high.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
