Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, and more specifically, to an integrated precision stator core machine base. Background Art

[0002] The stator core frame is a very important component of the generator or motor. The main function of the stator core frame is to serve as the support structure of the stator core laminations, bear the torque of the stator, and transmit it to the base; as well as constitute the support structure of the bearing and frame. The frame ensures the stability and mechanical strength of the stator core, which is crucial to ensure the stability and safety of the motor operation.

[0003] Some existing stator core bases are equipped with heat dissipation fins on their surfaces to dissipate heat. However, if the equipment is used for a long time and only dissipates heat through the heat dissipation fins, the heat dissipation efficiency of the equipment may be reduced, thereby affecting the subsequent operation of the equipment. Therefore, in order to solve the above problems, we propose an integrated precision stator core base. Utility Model Content

When the equipment is running, the heat is dissipated through the first heat sink and the second heat sink, and the heat is absorbed and discharged through the heat transfer oil, which is beneficial to improve the heat dissipation efficiency of the equipment. The sound-absorbing cotton can absorb noise, which is beneficial to reduce the noise value generated when the equipment is running, and a protective component is provided on the outside of the shell to protect the shell, which is beneficial to reduce the damage to the shell caused by direct impact of foreign objects.

[0008] By adopting the above technical solution, the outer side of the shell plays a role of protecting the shell through the setting of the protective ring, which helps to prevent the shell from being directly hit by foreign objects, and further helps to reduce the damage to the shell caused by the impact.

[0009] Furthermore, a plurality of through holes distributed in a linear array are formed on the side wall of the first heat sink, and a plurality of the first heat sinks and the second heat sinks are staggered on the side wall of the housing.

[0010] By adopting the above technical solution, through holes are opened on the side wall of the first heat sink to facilitate air circulation, thereby facilitating the improvement of the heat dissipation efficiency of the device.

[0011] Furthermore, two symmetrically distributed stabilizing blocks are provided on opposite sides of the two supports, and shock-absorbing pads are provided on the bottom ends of the two supports.

[0012] By adopting the above technical solution, the outer side of the support plays a role of supporting and stabilizing the support through the setting of a stabilizing block, which is beneficial to maintaining the stability of the support during use, and further beneficial to maintaining the stability of the placement of the shell. The bottom end of the support can play a shock-absorbing role through the setting of a shock-absorbing pad.

[0013] Furthermore, a sealing ring matching the inner diameter of the cavity is fixedly installed on the sealing plate near the shell side, a plurality of positioning blocks distributed in a circular array are fixedly installed on the sealing plate near the shell side, and a positioning groove matching the positioning block is opened on the shell near the sealing plate side.

[0014] By adopting the above technical solution, a sealing ring is provided on one side of the sealing plate, and the size of the sealing ring is the same as the inner diameter of the cavity, which is conducive to maintaining the sealing between the sealing plate and the shell, reducing the possibility of leakage of the heat transfer oil, and a positioning block is provided on one side of the sealing plate, which is engaged with the positioning groove opened in the side wall of the shell to play a role in positioning and stabilizing the sealing plate, which is convenient for subsequent screwing.

[0015] In summary, the utility model includes the following beneficial technical effects:

[0016] (1) In the utility model, the first heat sink and the second heat sink cooperate to dissipate heat, and a cavity is provided in the shell, which is filled with heat-conducting oil to further dissipate heat.
