The invention relates to the technical field of sealing structures, in particular to a rotary sealing structure for coal mine machinery, which includes a base shell, a bearing is provided at one end of the base shell, a rotating shaft is sleeved on the bearing, and a first seal is provided at the end of the rotating shaft close to the bearing. The end of the rotating shaft far away from the bearing is provided with a second sealing ring, the shaft of the rotating shaft between the second sealing ring and the first sealing ring is covered with a sleeve, and the end of the upper surface of the base shell close to the first sealing ring is provided with a There is a first airtight door, and a second airtight door is arranged on the base shell below the first airtight door, and an oil inlet pipe runs through the first airtight door, and an oil outlet pipe runs through the second airtight door, and the second airtight door in the base shell A sealing packing is filled between the first sealing ring and the second sealing ring. The invention can effectively prevent fine coal powder particles from entering the bearing during use, thereby ensuring the service life of the rotating mechanism and improving the production efficiency of the equipment. The whole mechanism is simple to use and easy to maintain, and has strong practicability.
Description
technical field [0001] The invention relates to the technical field of sealing structures, in particular to a rotary sealing structure for coal mine machinery. Background technique [0002] In the mechanical equipment used in coal mines, most of the mechanical equipment needs to be used from the rotating mechanism. Due to the special environment of the coal mine, when the equipment is running, fine coal particles are easy to enter the rotating mechanism. After the rotating mechanism enters the coal powder , with the long-term operation of the equipment, it will cause damage to the interior of the rotating mechanism, which will cause equipment damage and reduce the working efficiency of the equipment. To this end, we propose a rotary seal structure for coal mine machinery. Contents of the invention [0003] The object of the present invention is to solve the shortcoming that fine coal powder particles easily enter the rotating mechanism and cause damage to the rotating mec...
