Description

[0002] Oil-cooled motors are motors that use oil-immersed cooling. They use the high thermal capacity and stability of oil to dissipate heat, thereby ensuring efficient operation of the motor. Oil-cooled motors are usually used in industrial production, such as machine tool processing, presses, punching machines, etc. With the development of modern technology, the use of oil-cooled motors has become increasingly frequent, and their functions are constantly being improved, making them more convenient to use.

[0003] In view of this, Chinese patent number CN110932475B proposes an oil-cooled motor. The oil-cooled motor provided by the present invention performs spraying, pouring, and throwing oil cooling on different surfaces of the armature assembly, and the cooling effect is good. However, for the method of immersing the motor in oil for heat dissipation cooling, if the oil is immersed in the oil for a long time, the heat will always be difficult to dissipate in the oil. Even if the spraying method is adopted, it will take a certain amount of time to dissipate the heat. The continuous operation of the motor is likely to cause the heat to dissipate too slowly, causing the internal stator and rotor to work unstable, thereby affecting the use of the motor. In this regard, this design scheme proposes an oil-cooled motor. Utility Model Content

[0025] A protective shell 208 is inserted at the upper edge of the inner wall of the installation slot 202, and a plurality of air inlet slots 209 are equidistantly provided on the top of the protective shell 208. The protective shell 208 is detachable to facilitate maintenance of the fan 203 in the installation slot 202.

[0026] Furthermore, an oil inlet hole 4 is opened at one end of one side of the outer wall of the casing 1, and a sealing plug 5 is inserted into the inner wall of the oil inlet hole 4, and the outer wall of the sealing plug 5 is threadedly connected to the inner wall of the oil inlet hole 4. The motor body 3 is installed in the casing 1 and sealed by the sealing mechanism 9, and then the sealing plug 5 is screwed out, and cooling oil is injected through the oil inlet hole 4. After it is filled, the sealing plug 5 is screwed in to seal it, and the oil cannot overflow from the oil inlet hole 4.

[0027] A buffer pad 6 is fixedly provided at one end of the inner wall of the casing 1, and a first sealing gasket 7 is fixedly provided at the other end of the inner wall of the casing 1, and the inner wall of the buffer pad 6 and the inner wall of the first sealing gasket 7 are respectively in contact with the two sides of the outer wall of the motor body 3, and a threaded groove 8 is provided at the edge of one end of the casing 1, and the buffer pad 6 plays a role of buffering and shock absorption when the motor body 3 is driven, and the first sealing gasket 7 plays a role of preliminary sealing when oil is injected, so that the oil is not easy to leak out and contact the sealing cover 901;

[0030] Working principle: When using the oil-cooled motor in this design, first, the motor body 3 needs to be installed inside the casing 1, and supported by the buffer pad 6 so that it can be buffered during operation to reduce the vibration amplitude of the equipment. At the same time, the motor body 3 is contacted by the first sealing gasket 7 at the edge of the inner wall of the casing 1, which can initially seal the cooling oil, so that the oil is deposited around the outer wall of the motor body 3 to soak it.

The overall cooling speed of the cover design is faster, and the heat in the cooling oil can be exported in time to prevent the motor from being unusable due to slow heat dissipation when the motor continues to work, thereby improving the protection of the device. When installing the oil-cooled motor, the motor body 3 is installed in the casing 1 and then the sealing cover 901 is screwed into the threaded groove 8 on one side of the casing 1 through the threaded ring 902. The connection area is sealed through the second sealing gasket 903. At the same time, the output end of the motor body 3 passes through the through hole on one side of the sealing cover 901 and contacts with the third sealing gasket 904 to achieve sealing and prevent oil from leaking from the gap.
