Description

Technical Field

[0001] The invention relates to the technical field of asynchronous motors, and in particular to a self-lubricating sliding bearing asynchronous motor structure. Background Art

[0002] At present, domestic sliding bearing motors require external platforms to provide oil stations or install oil-water coolers on the motors.

[0003] The oil-water cooler and the oil station both require separate power supplies, are costly, have complex systems, and have poor reliability. In order to improve the reliability of the power system, it is necessary to improve the existing sliding bearing motor. Summary of the invention

[0004] Based on the fact that the sliding bearing motors proposed in the background technology require an external platform to provide an oil station or an oil-water cooler to be installed on the motor, which leads to the technical problems of requiring separate power supply, high cost, complex system and poor reliability, the present invention proposes a self-lubricating sliding bearing asynchronous motor structure. Compared with the existing sliding bearing motor, the bearing is improved and a self-lubricating sliding bearing is used. The two bearings and the lubricating oil can be fully cooled by only supplying cooling water to the front and rear bearings in two ways. The lubricating oil inside the bearing ensures that the oil film fully and evenly covers the surface of the bearing shell.

[0005] The present invention proposes a self-lubricating sliding bearing asynchronous motor structure, comprising an asynchronous motor body, self-lubricating sliding bearings are installed at the shaft positions at both ends of the asynchronous motor body, two self-lubricating sliding bearings are provided with bearing cooling water sealing shells, and the two bearing cooling water sealing shells are externally connected to cooling water pipelines through self-lubricating bearing water inlet and outlet flanges;

[0006] The asynchronous motor body is provided with a motor water cooling shell, and the motor water cooling shell is connected to two motor cooling water inlet and outlet flanges, and the cooling water pipeline is communicated with the motor cooling water inlet and outlet flanges.

[0007] Preferably, the external cooling water pipeline is composed of two conduits, and both ends of the two conduits are respectively connected to two bearing cooling water sealing shells, and the middle parts of the two conduits are connected to two motor cooling water inlet and outlet flanges.

[0008] Preferably, the motor cooling water inlet and outlet flanges are externally connected to a cooling water circulation assembly, and the cooling water circulation assembly includes a circulating water pump and a cooling water tank.

[0009] Preferably, the water inlet of the circulating water pump is connected to one of the motor cooling water inlet and outlet flanges through a conduit, and the water outlet of the circulating water pump is connected to the cooling water tank through a conduit, and the cooling water tank is connected to the other motor cooling water inlet and outlet flange through a connecting pipe.

[0010] Preferably, a water cooler circulating water circuit is formed between the bearing cooling water sealing housing, the cooling water pipeline, the motor water cooling shell, the circulating water pump and the cooling water tank.

[0011] When the motor is running, cooling water is introduced from one motor cooling water inlet and outlet flange, and the cooling water cools the sliding bearing and the motor through the cooling water pipeline and the self-lubricating bearing inlet and outlet flange. The heated cooling water is pumped into the cooling water tank from the other motor cooling water inlet and outlet flange through a circulating water pump for cooling, thus forming a circulation loop.

[0012] The beneficial effects of the present invention are:

[0013] The self-lubricating sliding bearing asynchronous motor structure proposed in the present invention improves the bearing cooling structure and uses a self-lubricating sliding bearing. It only needs to distribute cooling water to the front and rear bearings in two ways to fully cool the two bearings and the lubricating oil. External equipment such as an external oil circuit and an oil-water cooler can be omitted. The motor body and the sliding bearing are cooled by external cooling water, which effectively avoids the oil leakage phenomenon that often occurs in the motor using the sliding bearing, and at the same time eliminates the external equipment and maintenance costs.
