Problems solved by technology
Among them, the reliability of the comb tooth oil gear is poor, and the contact oil gear is easy to induce vibration of the shaft system. The existing air-sealed oil gear needs dry air to seal, and the air moisture content is very high. When the air quality control is not good, it will The water in the lubricating oil will bring risks to the safe operation of the steam turbine generator set

The embodiment of the present application provides a hermetic seal oil gear applied to bearings, which can prevent the lubricating oil in the bearing box in the turbogenerator set from leaking out of the bearing, and can also prevent water vapor and sundries outside the bearing box Enter the bearing box and contaminate the lubricating oil. It includes a ring-shaped housing. A positive pressure sealing groove and a negative pressure extraction groove are arranged inside the housing. Both the positive pressure sealing groove and the negative pressure extraction groove are annular grooves. There is a partition, the partition is used to separate the positive pressure sealing groove and the negative pressure extraction groove; the housing is provided with an air inlet near the outside of the bearing box, and the air inlet is used to introduce the compressed air outside the housing into the positive pressure seal In the groove; a ventilation hole is arranged on the partition, one end of the ventilation hole is connected with the positive pressure sealing groove, and the other end of the ventilation hole is connected with the negative pressure extraction groove, and the ventilation hole is used to introduce compressed air into the negative pressure extraction groove.
Description
Technical field [0001] The present application relates to the field of mechanical manufacturing, and more particularly to an airtight sealing gear gear and a turbine generator set applied to the bearing. Background technique [0002] The oil gear of the steam wheel generator is a device that prevents lubricating oil leakage and prevents foreign matter, water vapor or the like to contaminate lubricating oil inside the bearing. [0003] At present, the main oil gear of the steam wheel generator has a comb and a contact floating oil gear, and is generally sealed. Among them, the reliability of the comb is poor, the contact fuel gear is easy to induce the axial vibration, and the existing airtight sealing oil is required to be sealed, and the air water content is high. When the air quality is not good, Make the lubricant with water and bring risks to the safe operation of the turbine generator set. [0004] It can be seen that the inventive oil gear to prevent water vapor from enteri...
