2. dead point phenomenon of poor starting (or not when turning when the starting of intermittence) (product on certain point, can not start when stopping) 3.
Product electric current becomes larger, and 4. lives of product shorten.
Utility model content
The main purpose of the utility model is to provide a kind of bearing reasonable for structure and rotor assembling structure, it is intended to ensure to turn
Son rotation is smooth, and the control of part concentricity is good.
The utility model proposes a kind of bearing and rotor assembling structure, including rotor and bearing, the rotor includes cylindricality
Rotor assembly and the shaft that is axially disposed on the central shaft of the rotor assembly, the rotor assembly be point with the shaft
Body is arranged, and the axial centerline of the rotor assembly is provided through the installation through-hole being adapted to the shaft, the installation
The upper end position of through-hole is provided with the upper bearing (metal) installation position for installing bearing with the bearing adapter, the installation through-hole
Lower end position is provided with the lower bearing installation position for installing bearing with the bearing adapter, and two bearings are respectively assembled at
In the upper bearing (metal) installation position and the lower bearing installation position, the shaft is installed through in the installation through-hole, described turn
Axis connects with the bearing axis.
Preferably, further include that casing and lid set lid on the housing, be equipped in the casing and the rotor set
The rotor installation position of part adaptation is installed in the case where the lower end of the rotor installation position is equipped with the shaft being adapted to the lower end of the shaft
Position is equipped with installation position in the shaft being adapted to the upper end of the shaft, the lower end fixing assembling of the shaft in the lid
Under the shaft in installation position, the upper end of the shaft is securely fitted in the shaft in installation position, the rotor assembly
Rotatably it is mounted in the rotor installation position.
The beneficial effects of the utility model are：
Rotor assembly in this product and shaft are split settings, the axial centerline of rotor assembly be provided through with
The installation through-hole of shaft adaptation, the upper end position of installation through-hole is provided with pacifies with the upper bearing (metal) for installing bearing of bearing adapter
Position is filled, the lower end position of installation through-hole is provided with the lower bearing installation position for installing bearing with bearing adapter, two bearings point
It is not assemblied in upper bearing (metal) installation position and lower bearing installation position, shaft is installed through in installation through-hole, and shaft connects with bearing axis.
When this product is installed, by shaft and other parts fixing assembling, the installation of rotor is completed.
This product rotates for rotor assembly, and the fixed structure of shaft, upper and lower ends bearing need to only be assembled with rotor assembly, nothing
Need it is secondary separately assemble bearing and parts, have some setbacks there is no product rotation caused by because of the reason of the combination and assembling die
Problem can effectively ensure the concentricity of product, while can effectively avoid four kinds of bad problems in technical background.
