Abstract
The bearingless generator comprises: a stator, a rotor to coaxial couple directly with original rotation shaft of prime mover, a binding bolt for rotor to cross rotor center and connect with said prime shaft, and an erection bolt for stator to fixed connect directly the stop end of generator with the one of the prime mover. This invention saves two bearings and end caps, has simple structure and light weight, releases labor, and improves generator performance.
Description
Technical field
The present invention relates to a kind of generator without bearing.
Background technology
As everyone knows, traditional generator rotor structure form is the duplex bearing supporting construction.Last century end has occurred single shaft again and has held the generator of supporting construction form, and has obtained using widely.The generator of a kind of form in back not only lacks a front end housing than preceding a kind of generator, has reduced the volume and weight of motor, and the precision of the rotating shaft concentricity of generator when docking with prime mover also will height.
Summary of the invention
The purpose of this invention is to provide a kind of generator without bearing, reduce the volume and weight of motor, generator Structure is simpler, and improves the hydro-generator ventilation radiating effect, reduces the temperature rise of motor.
The present invention realizes like this, it comprises generator unit stator, generator amature, generator amature fastening bolt, stator construction bolt, it is characterized in that generator amature no bearing in front and back and front and rear cover, generator amature directly is connected with the rotating shaft of prime mover is coaxial, the generator amature fastening bolt passes rotor center and prime mover rotating shaft is fastenedly connected, the generator unit stator construction bolt is fastenedly connected the seam of generator unit stator seam direct and prime mover, and the generator rear end connects protective cover.
The present invention has deducted two bearings and end cap, and electric machine structure is simple, and volume is little, in light weight, manufacturing process is easy, alleviated labour intensity, save raw material, motor length shortens, makes that wind path is short and intake is big, electric machine temperature rise reduces, and increases the capacity nargin of motor.
Description of drawings
Fig. 1 is a general assembly schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention includes generator unit stator (3), generator amature (4), generator amature fastening bolt (5), stator construction bolt (6), it is characterized in that generator amature no bearing in front and back and front and rear cover, generator amature (4) directly with coaxial connection of rotating shaft of prime mover (1), generator amature fastening bolt (5) passes rotor center and prime mover rotating shaft (2) is fastenedly connected, generator unit stator construction bolt (6) is fastenedly connected the seam of generator unit stator seam direct and prime mover, and the generator rear end connects protective cover (7).
