Description

Technical Field

[0001] This utility model relates to the technical field of bearing housings, and in particular to a variable frequency permanent magnet motor bearing housing with a heat dissipation structure. Background Technology

[0002] The shaft of a variable frequency permanent magnet motor is mainly connected to the frame through a bearing housing. During use, the bearing housing generates a lot of heat due to the rotation of the bearing. Especially in summer, the heat dissipation is slow, which can easily cause damage to the bearing. The heat is also transferred to the motor through the shaft. Existing heat dissipation methods are all natural heat dissipation, and the common method is to install ventilation pipes on the bearing housing for heat dissipation. This heat dissipation method is inefficient in actual use. Therefore, this application provides a variable frequency permanent magnet motor bearing housing with a heat dissipation structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a variable frequency permanent magnet motor bearing housing with a heat dissipation structure, so as to solve the problem of low heat dissipation efficiency and poor effect of the bearing housing in the prior art described in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a variable frequency permanent magnet motor bearing housing with a heat dissipation structure, comprising...

[0005] The bearing housing body has an annular oil cavity inside;

[0006] The pit is located on the ground, and several troughs are also provided at the bottom of the pit.

[0007] The oil tank is placed at the bottom of the pit, and cooling boxes connected to the oil tank are installed at the lower end of the tank corresponding to the position of the tank.

[0008] Several partitions are respectively installed inside the oil tank and extend into the corresponding cooling boxes, forming a flow channel with the partitions, oil tank, and cooling boxes;

[0009] An oil pump is located at one end of the flow channel and is connected to one end of the oil chamber through a feed pipe.

[0010] The liquid inlet pipe is located at the other end of the flow channel, and it is connected to the other end of the oil chamber through the discharge pipe.

[0011] Preferably, the outer wall of the cooling box is provided with several heat dissipation fins inserted into the soil.

[0012] Preferably, a support net is provided on the ground at the pit opening, and the feed pipe and discharge pipe pass through the support net respectively.

[0013] The beneficial effects of adopting the above technical solutions are:

[0014] This application utilizes an oil pump to deliver grease from the flow channel to the oil chamber via the feed pipe. As the grease passes through the oil chamber, it carries away the heat energy from the bearing housing body. It then flows back into the flow channel through the discharge pipe. As the grease carrying heat passes through the flow channel, the soil absorbs the heat energy of the grease through the cooling box, thus cooling the grease. The grease is then pumped back into the oil chamber, forming a cycle. This application uses soil to cool the grease, which can effectively reduce costs. Attached Figure Description

[0016] Figure 2 This is a cross-sectional view of the fuel tank of this utility model.

[0017] The components include: ground 10, bearing housing body 20, oil cavity 21, pit 30, trough 31, support net 40, oil tank 50, cooling box 51, partition 52, flow channel 53, liquid inlet pipe 54, discharge pipe 55, oil pump 56, feed pipe 57, and heat sink 60. Detailed Implementation

[0018] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-2 In this first embodiment, a variable frequency permanent magnet motor bearing housing with a heat dissipation structure includes...

[0020] The bearing housing body 20 has an annular oil cavity 21 inside;

[0021] The pit body 30 is set on the ground, and the bottom of the pit body 30 is also provided with several troughs 31;

[0022] The oil tank 50 is placed at the bottom of the pit 30. At the lower end of the oil tank 50, a cooling box 51 connected to the oil tank 50 is provided at the position corresponding to the position of the tank 31.

[0023] Several partitions 52 are respectively installed in the oil tank 50 and extend into the corresponding cooling box 51. The partitions 52, the oil tank 50, and the cooling box 51 form a flow channel 53.

[0024] Oil pump 56 is located at one end of flow channel 53 and is connected to one end of oil chamber 21 through feed pipe 57;

[0025] The liquid inlet pipe 54 is located at the other end of the flow channel 53, and the liquid inlet pipe 54 is connected to the other end of the oil chamber 21 through the discharge pipe 55.

[0026] This embodiment is implemented as follows:

[0027] In use, the cooling grease in the oil tank 50 is pumped by the oil pump 56 and sent to the oil chamber 21 through the feed pipe 57. When the cooling grease passes through the oil chamber 21, it absorbs the heat energy from the bearing housing body 20 where the oil chamber is located. The grease that has absorbed heat enters the oil tank 50 through the discharge pipe 55 and the liquid inlet pipe 54, and is then sucked away by the oil pump 56 again through the flow channel 53. When the grease that has absorbed heat passes through the flow channel 53, the heat energy of the grease is absorbed by the soil through the side wall of the cooling box 51, thus achieving the cooling of the grease and enabling circulation.

[0028] Please see Figure 1 The outer wall of the cooling box 51 is provided with several heat dissipation fins 60 inserted into the soil.

[0029] This application improves the heat dissipation efficiency of grease by using heat sinks 60 provided on the cooling box 51.

[0030] Please see Figure 1 A support net 40 is provided on the ground at the pit opening of the pit body 30, and the feed pipe 57 and the discharge pipe 55 pass through the support net 40 respectively.

[0031] This application uses a support net 40 to seal the pit opening of the pit body 30, preventing workers from falling in.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
