Description
Technical Field
The utility model belongs to the technical field of the motor, concretely relates to fan rotor shaft suitable for high-speed operation.
Background
High-speed motors are generally motors with a rotational speed of more than 10000r/min, which are required to be high because of the high rotational speed, and on the contrary, motors used as driving fans are required to have a small size, especially axial flow fans. Because of the influence of air on the reaction force of the fan, the motor rotor shaft is subjected to larger axial force in the working process, so that the axial abrasion of the bearing is serious, the axial gap is increased, the motor rotor shaft can be obviously felt to shake when the motor is driven, and the stable operation and the service life of the motor are seriously influenced.
Disclosure of Invention
In order to overcome the problems that the axial abrasion of a bearing is serious and the axial clearance is increased due to the fact that a motor rotor shaft in the background technology is subjected to a larger axial force in the working process, the motor rotor shaft can be obviously felt to shake when a motor is driven, and the stable operation and the service life of the motor are seriously influenced, the utility model provides a fan rotor shaft which can stably operate and is suitable for high-speed operation; the gap generated by abrasion in the working process can be adjusted and compensated, the shaking of the motor rotor shaft is reduced, the abrasion is reduced, and the service life is prolonged.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a fan rotor shaft mainly includes frame, pivot, rotor core, commutator, kicking block suitable for high-speed operation, rotor core, commutator fixed mounting in the pivot, the pivot is installed in the frame through two tapered roller bearing radial spacing, the pivot front end is through the spacing installation of shaft shoulder and thrust bearing in the frame, the pivot rear end is through the spacing installation of kicking block and thrust bearing, through the adjustable installation of thin screw thread between kicking block and frame.
The top block is provided with a straight-line-shaped adjusting block or an inner hexagonal hole which is convenient to bear force during adjustment.
The utility model has the advantages that:
the utility model discloses can adjust the clearance that wearing and tearing produced in the kicking block compensation course of work, reduce the shake of electric motor rotor axle, the noise abatement, reduce wearing and tearing, increase of service life.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
The utility model discloses a fan rotor shaft suitable for high-speed operation, a fan rotor shaft suitable for high-speed operation mainly include frame 1, pivot 2, rotor core 3, commutator 4, kicking block 5, rotor core 3, commutator 4 fixed mounting on pivot 2, pivot 2 is installed in frame 1 through two tapered roller bearing 6 radial spacing, reduce the friction and prevent pivot 2 radial runout, pivot 2 front end is installed in frame 1 through shoulder and thrust bearing 7 spacing, pivot 2 rear end is installed through kicking block 5 and thrust bearing 7 spacing, avoid in the motor working process, the axial force that fan and wind interact produced leads to axial displacement, adjustable installation is passed through thin screw thread between kicking block 5 and frame 1; the top block can be adjusted to compensate the gap and the bearing gap generated by abrasion in the working process, so that the shaking of the motor rotor shaft is reduced, the noise is reduced, the abrasion is reduced, and the service life is prolonged. The top block 5 is provided with a straight-line-shaped adjusting block or an inner hexagonal hole which is convenient to bear force during adjustment.
The working process is as follows:
after the components are sequentially installed, the internal clearance and the bearing clearance are adjusted by adjusting the jacking block 5; when the bearing clearance is increased due to friction after working for a period of time, the bearing does not need to be replaced, the jacking block 5 can be adjusted to compensate the clearance and the bearing clearance generated by abrasion in the working process, the shake of the motor rotor shaft is reduced, the noise is reduced, the abrasion is reduced, and the service life is prolonged.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
