Abstract
The invention relates to the technical field of motors, in particular to a motor shaft. The motor shaft comprises a shaft body, and is characterized in that the shaft body comprises a first half shaft and a second half shaft, wherein external threads are formed at the rear end of the first haft shaft; internal threads corresponding to the external threads are formed at the front end of the second half shaft; the first half shaft is connected with the second half shaft through the internal and external threads; knurls and ceramic membranes are arranged on peripheral surfaces of both the first half shaft and the second half shaft. The motor shaft is convenient for motor assembly and can improve the assembly efficiency.
Description
Technical field
The present invention relates to technical field of motors, be specifically related to a kind of motor shaft.
Background technique
Motor is used to the conversion equipment realizing electric energy and mechanical energy and mechanical energy and electric energy, it is the main driver part in modern industry system, the rotor of existing magneto is made up of motor shaft, magnetic shoe and rotor cap, carrying out in rotor assembling production process, by screw, key or locating stud etc., rotor cap and magnetic shoe need be interfixed, be fixed on motor shaft by rotor cap again, whole process operation is loaded down with trivial details, is difficult to improve packaging efficiency.
Summary of the invention
For the problems referred to above, the invention provides and a kind ofly facilitate motor to assemble and the motor shaft of installation efficiency can be improved, and the wear resistance of motor shaft can be improved, solve existing motor after a long time use, magnetic shoe, occur between rotor cap and motor shaft trickle loosen or be shifted, cause power of motor performance and durability reduction problem.
Realize technological scheme of the present invention
Motor shaft, comprise axle body, described axle body comprises the first semiaxis and the second semiaxis, described the first half shaft rear ends are provided with outside thread, second semiaxis front end is provided with the internal thread corresponding with the first half shaft rear end outside threads, described first semiaxis is connected by internal and external screw thread with the second semiaxis, and described first semiaxis and the second semiaxis perimeter surface are equipped with and are provided with annular knurl and ceramic membrane.
Described first semiaxis front end is provided with jump-ring slot.
Described second semiaxis is provided with positive stop lug boss.
Adopt such scheme, because motor shaft axle body comprises the first semiaxis and the second semiaxis, first semiaxis and the second semiaxis are threaded connection, and motor can be facilitated to assemble, and improve installation efficiency, because motor shaft body is provided with annular knurl and ceramic membrane, the wear resistance of motor shaft body can be improved, and solve motor after a long time use, magnetic shoe, occur between rotor cap and motor shaft to loosen or be shifted, cause the problem that power of motor performance and durability reduce.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the first semiaxis in the present invention.
Fig. 3 is the structural representation of the second semiaxis in the present invention.
In figure, 1 is axle body, and 2 is the first semiaxis, and 3 is the second semiaxis, and 4 is outside thread, and 5 is annular knurl, and 6 is positive stop lug boss, and 7 is jump-ring slot.
Embodiment
As shown in the figure, motor shaft, comprise axle body 1, described axle body comprises the first semiaxis 2 and the second semiaxis 3, described first semiaxis 2 rear end is provided with outside thread 4, second semiaxis 3 front end is provided with the internal thread corresponding with the first semiaxis 2 rear end outside thread 4, in described first semiaxis 2 and the second semiaxis 3 pass through, outside thread connects, because motor shaft axle body 1 comprises the first semiaxis 2 and the second semiaxis 3, first semiaxis 2 and the second half 3 axle are threaded connection, motor can be facilitated to assemble, improve installation efficiency, first semiaxis 2 front end is provided with jump-ring slot 7, second semiaxis 3 is provided with positive stop lug boss 6, bearing then can be installed from the other end of the second semiaxis 3, improve installation efficiency, described first semiaxis 2 and the second semiaxis 3 perimeter surface are equipped with and are provided with annular knurl 5 and ceramic membrane, the wear resistance of motor shaft body can be improved, and solve motor after a long time use, magnetic shoe, occur between rotor cap and motor shaft to loosen or be shifted, cause the problem that power of motor performance and durability reduce.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
