Abstract
The utility model relates to an integrated bearing support structure of an auto battery cooling fan. The integrated bearing support structure of the auto battery cooling fan is characterized by comprising a stator iron core and a bearing seat, wherein the bearing seat is arranged in a mounting hole of the stator iron core in an inserting mode. Coaxial stepped holes for fixing two bearings are formed in the front end and the back end of the bearing seat, a through hole is formed between the two stepped holes, and a motor shaft passes through the through hole. According to the integrated bearing support structure of the auto battery cooling fan, due to the fact that rolling bearings replace sliding bearings, the service lives of the bearings are prolonged. Due to the fact that the integrated bearing seat replaces two independent and separated bearing seats in the traditional art, the problem that the bearings are mounted uncoaxially is solved, and the assembly accuracy of the fan is improved. The integrated bearing support structure of the auto battery cooling fan has the advantages of being simple in structure, low in cost, high in assembly accuracy and good in mechanical property.
Description
Technical field:
The utility model relates to a kind of solid box supporting construction of automobile batteries cooling fan, belongs to mechanical field.
Technical background:
The car air-conditioner blower fan is brush motor or brushless electric machine by the definite purpose motor of its driving, can abbreviate brush blower fan and brushless blower fan respectively as.Wherein brushless blower fan is followed the rotor difference that motor shaft rotates together, can be divided into external rotor brushless blower fan and inner-rotor brushless blower fan again.Present external rotor brushless blower fan adopts sliding bearing basically, and bearing fixing is at two independently on the bearing pedestal, and two bearings and bearing pedestal thereof are fixed on the stator core again.Because there is the lamination error in stator core, and two independently bearing pedestal be independent processing, the coaxiality error of two bearings is very big after assembling, can't satisfy the production requirement of blower fan, has influenced the mechanical performance index of brushless blower fan.In addition, the useful life of sliding bearing is short than rolling bearing life, has influenced the useful life of brushless blower fan.
Summary of the invention:
The purpose of this utility model is to provide a kind of solid box supporting construction of automobile batteries cooling fan, make structure make the axiality of the two bearings after the assembling not be subjected to the influence of the rigging error of stator lasmination sum of errors bearing pedestal, improve the assembly process process of brushless blower fan, significantly improved the mechanical performance index of brushless blower fan.
The technical solution of the utility model is as follows:
The solid box supporting construction of the utility model automobile batteries cooling fan, it is characterized in that: comprise stator core and be located in the interior bearing pedestal of stator core installing hole, described bearing pedestal front and back end is provided with for the fixing coaxial stepped hole of two bearings, is provided with a through hole that is used for passing motor shaft between described two stepped holes.
The bearing of said fixing on two coaxial stepped holes is rolling bearing.
Above-mentioned bearing pedestal is the cover tubular.
Be fixedly connected with base plate on the above-mentioned bearing pedestal, bearing pedestal and base plate are made one.
Above-mentioned bearing pedestal and cooperating of stator core installing hole are stationary fit or for movingly.
The utility model solid box supporting construction, owing to substituted sliding bearing with rolling bearing, increased the useful life of bearing, substituted two bearing pedestals of traditional independent separate with all-in-one-piece bearing pedestal, solve the disalignment problem that bearing is installed, improved the assembly precision of blower fan.Have simple in structure, cost is low, assembly precision is high and the remarkable advantage of good mechanical property.
Description of drawings:
Fig. 1 is organigram of the present utility model;
Embodiment:
In order fully to disclose the technical solution of the utility model, be illustrated below in conjunction with embodiment.
The solid box supporting construction of the utility model automobile batteries cooling fan, comprise stator core 1 and the bearing pedestal 3 that is located in the stator core installing hole 2, described bearing pedestal 3 front and back ends are provided with for the fixing coaxial stepped hole 5 of two bearings 4, and 5 are provided with a through hole 6 that is used for passing motor shaft 8 between described two stepped holes.
In order to prolong the useful life of bearing, the bearing of said fixing on two coaxial stepped holes is rolling bearing.
For reasonable in design, above-mentioned bearing pedestal is the cover tubular.Be fixedly connected with base plate 7 on the above-mentioned bearing pedestal, bearing pedestal 3 is made one with base plate.
In order to use needs, above-mentioned bearing pedestal and cooperating of stator core installing hole are stationary fit or for movingly.
The utility model solid box supporting construction, owing to substituted sliding bearing with rolling bearing, increased the useful life of bearing, substituted two bearing pedestals of traditional independent separate with all-in-one-piece bearing pedestal, solve the disalignment problem that bearing is installed, improved the assembly precision of blower fan.Have simple in structure, cost is low, assembly precision is high and the remarkable advantage of good mechanical property.
Embodiment one:
As shown in Figure 1, integrated shaft bearing 3 is working of plastics, and bearing pedestal 3 is pressed in the stator core 5 by cooperation, and two rolling bearing 4 fit systems are pressed in the bearing pedestal 3.Motor shaft 8 cooperations are installed on the rolling bearing 4, and it is fixing to reorder.
Embodiment two:
As shown in Figure 1, integrated shaft bearing 3 is metalwork, and bearing pedestal 3 is pressed in the stator core 5 by cooperation, and two rolling bearing 4 fit systems are pressed in the bearing pedestal 3.Motor shaft 8 cooperations are installed on the rolling bearing 4, and it is fixing to reorder.
Embodiment three, embodiment four and embodiment one, two difference are that the bearing pedestal 3 of embodiment three, embodiment four makes one with base plate.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
