Description

Technical Field

[0001] The utility model relates to the field of resolver rotors, in particular to an integrated rotating shaft with a resolver rotor. Background Art

[0002] A rotating shaft is an essential component for connecting the main parts of a product and is used to rotate and work under both bending moment and torque. There are many types of rotating shafts, and the rotating shaft integrated with a resolver rotor is one of them.

[0003] For the traditional rotating shaft with a resolver rotor, the resolver rotor and the bearing are of a separated structure. When connecting the resolver rotor and the bearing, first, multiple operations such as drilling are required on the bearing, and then the resolver rotor and the bearing are manually connected. The operation is rather troublesome, time-consuming, reducing the production efficiency of the rotating shaft. At the same time, during the installation process, good centering cannot be achieved, and the resolver stator cannot be well accommodated in the height direction. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide an integrated rotating shaft with a resolver rotor.

[0005] The integrated rotating shaft with a resolver rotor provided by the utility model adopts the following technical solutions:

[0006] An integrated rotating shaft with a resolver rotor includes a shaft body and a resolver stator arranged at the end of the shaft body. On the end face of the shaft body where the resolver stator is arranged, a plurality of mounting holes are evenly arranged around the center of the end face, and magnetic conductive parts are installed in the mounting holes.

[0007] Further, the mounting holes include large holes for installing large-volume magnetic conductive parts and small holes for installing small-volume magnetic conductive parts. The large holes and the small holes are arranged alternately, and the magnetic conductive parts installed in the large holes and the small holes have the same shape.

[0008] Further, the mounting holes and the magnetic conductive parts are both cylindrical, and the magnetic conductive parts are installed in the mounting holes by interference fit.

[0009] Further, the large holes and the small holes are spaced 60°.

[0010] Further, an installation step for installing the resolver stator is arranged on the side wall of the shaft body.

[0011] In summary, the utility model has at least the following beneficial effects: Installing the magnetic conductive parts on the shaft body can realize the functions of the original resolver rotor, reduce the installation steps of the assembly, make the resolver rotor and the shaft body concentric, thereby improving the accuracy of the resolver rotor, with a simple structure and convenient processing.

[0016] The following uses specific specific examples to illustrate the implementation mode of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation modes.

[0017] The following combines the attached Figure 1-2 Further detailed description of the present utility model will be made.

[0018] The embodiment of the present utility model discloses an integrated rotating shaft with a resolver rotor. Refer to Figure 1 - Figure 2 , the integrated rotating shaft with a resolver rotor includes a shaft body 1 and a resolver stator 2 arranged at the end of the shaft body 1. A plurality of installation holes 3 are evenly arranged around the center of the end face at the end of the shaft body 1 where the resolver stator 2 is arranged. A magnetic conductive part 4 made of magnetic conductive material is installed in the installation hole 3. Installing the magnetic conductive part 4 in the installation hole 3 on the shaft body 1 can realize the function of the original resolver rotor. At the same time, the installation steps of the assembly will be reduced, so that the resolver rotor is concentric with the shaft body 1, thereby improving the accuracy of the resolver rotor. The structure is simple and the processing is convenient.

[0019] In this embodiment, the installation hole 3 includes a large hole 31 for installing a large-volume magnetic conductive part 4 and a small hole 32 for installing a small-volume magnetic conductive part 4. The magnetic conductive parts 4 installed in the large hole 31 and the small hole 32 have the same shape. By using one large and one small of the magnetic conductive part 4 to simulate different air gaps, the output waveform can achieve the effect of resolver.

[0020] In this embodiment, both the installation hole 3 and the magnetic conductive part 4 are cylindrical. The magnetic conductive part 4 is installed in an interference fit with the installation hole 3, and the installation is more compact.

[0021] In this embodiment, the large hole 31 and the small hole 32 are spaced 60°, so that the large hole 31 and the small hole 32 are evenly spaced, and three can be arranged on each end face of the shaft body 1.

[0022] In this embodiment, an installation step 11 for installing the resolver stator 2 is provided on the side wall of the shaft body 1, which facilitates the installation of the resolver stator 2 on the shaft body 1.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
