Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a forced lubrication bearing structure of a special motor for a mining counter-cyclonic fan. Background Art

[0002] Bearings, as an indispensable key component in modern mechanical equipment, play a vital role. Its core function is to firmly support the mechanical rotating body, thereby ensuring that the equipment can remain stable when running at high speed. In addition, bearings can significantly reduce the friction coefficient of the rotating body during movement, effectively reduce energy loss and wear, and extend the service life of the equipment. At the same time, the precise design and manufacturing of bearings ensure the rotation accuracy of the machinery, so that the equipment can maintain a high degree of accuracy and reliability during operation.

[0003] In order to increase the stability of the special motor for mining counter-cyclone blowers, two bearings are symmetrically fixed and connected on the surface of the rotor to ensure stable rotation of the rotor and the blades. When adding lubricating oil to the existing motor bearings, two pipes are required to add lubricating oil in turn, which is very inconvenient to add multiple times. However, the existing motor bearing structure cannot add lubricating oil to two bearing pipes at one time, which reduces the practicality of the motor bearing structure.

[0004] Therefore, it is necessary to provide a new forced lubrication bearing structure for a special motor for a mining counter-cyclone fan to solve the above technical problems. Utility Model Content
