Abstract
The utility model relates to a motor with a hollow shaft, belonging to the field of the motor manufacture. The utility model is characterized in that the shaft of the motor can be a hollow metal pipe, an impeller wheel is arranged on the inner wall of the hollow metal pipe, and the impeller wheel can be fixed at the bearing of the inner wall of the pipe shaft by adopting the weld method and other methods. The utility model has the advantages of novel design, low cost, easy fabrication and convenient operation, the volume, the weight and the noise can be reduced, and the motor can be one body with multiple functions; the motor for the purpose can have wide field and can be used as a water pump, a ventilation device, a supercharging device, a miniature hydro-generator, a propeller, etc.
Description
The utility model belongs to the motor manufacturing technology field.
Prior motor all is to drag miscellaneous equipment work by its rotation by transmission and conjunction device, as air blast, and the equipment of water pumper one class.But because the influence of its operational environment, motor internal is provided with fans or other cooling devices as motor, so from design angle, increases these self equipment and middle coupling arrangement, will inevitably bring complex structure, and noise increases, and volume increases.
The purpose of this utility model is: fluid class material in the transporting process, can not increased motor any equipment in addition itself, only depend on the design of its motor shaft, can be used to replace the function that plurality of devices is finished, reach one and use more.
Content of the present utility model is achieved in that its major technique feature is: its motor shaft is designed to hollow metal tube, at its hollow metal inside pipe wall impeller is housed, impeller adopts the method for welding to be fixed in tubular axis inwall bearing place.Also can adopt one-step moulding method, can also adopt fastener forms that impeller is installed.
The utility model has following advantage compared to existing technology:
1, reduces the integrated weight of motor device, volume, noise.
2, the many usefulness of one reduce cost, and make simple, easy to use.
Fig. 1 is the utility model hollow shaft motor master cutaway view.
Below in conjunction with accompanying drawing the utility model is described in further detail:
The design of hollow shaft motor mainly is to consider to utilize motor itself to realize dual purpose from designer's guiding theory.Suppose that hollow shaft motor uses as air blast, motor itself does not need external air blast.Electric motor starting, impeller 8 in the motor-hollow axle 7 is pressed into air in it, so just general mood can be pressed into the other end from hollow shaft 7 one ends, send into the equipment of required air blast, because motor is not to drive load by transmitting moment on the axle, therefore: the moment of torsion that hollow shaft 7 motors act on the axle is not very big, mainly is the weight and the moment that overcomes on the impeller 8 of bearing rotor on the axle.Therefore: hollow shaft motor has wide field on purposes, can be used as some special machines, as water pump, ventilation equipment, supercharging equipment small hydro turbine, propeller etc.
Description of drawings, rotor 1, stator 2, shell 3, end cap 4, bearing 5, sealing ring 6, hollow shaft 7, impeller 8.
Claims (2)
1, a kind of hollow shaft motor of being made up of stator and rotor endcap is characterized in that: hollow shaft 7 is metal tube, at its hollow shaft 7 inwalls impeller 8 is housed.
2, hollow shaft motor according to claim 1 is characterized in that: impeller 8 adopts the method for welding to be fixed in tubular axis inwall bearing 5 places, also can adopt one-step moulding method, can also adopt fastener forms that impeller is installed.
