Abstract
Type that economizes on fuel part slide bearing made of baked clay relates to slide bearing made of baked clay technique, and the purpose is in order to reduce the lubricated fuel feeding flow of slide bearing made of baked clay. Oil film oil inlet and the line at partial slide bearing body made of baked clay center and the contained angle 20 of horizontal flange, the oil film oil inlet is located horizontal flange retrograde rotation direction one side with the line at part slide bearing body made of baked clay center, axle bush body oil inlet is 20 with the line at partial slide bearing body made of baked clay center and the contained angle of horizontal flange, axle bush body oil inlet is located horizontal flange retrograde rotation direction one side with the line at part slide bearing body made of baked clay center. The beneficial effects of the utility model are that the appropriate oil feed angle of having selected has reduced the leakage of cold oil, has also blocked the oil that heaies up and has got back to the oil feed passageway again, reach bearing alloy effective cooling, reduce the purpose of bearing fuel feeding flow, be applicable to the steam turbine power generation unit.
Description
Technical field
The utility model relates to a watt sliding bearing technology.
Background technique
Along with the development of steam turbine technology, original Method of Small Scale Turbo-generator has not been suitable for the needs of the current economic development of China.The appearance of current Large-scale machine set especially AP1000 half speed nuclear power generating sets, make the size of bearing do larger and larger, the lubricants capacity of bearing also significantly increases thereupon, thus the buying of equipment and operating cost also increasing.
Bearing oil-feed angle is in the past selected in δ=45° angle place, 45° angle place is maximum place, bearing play, a large amount of oil is not just also utilized from then on bearing play place and has flowed away, the oil that another part heats up likely returns to bearing shell body filler opening by oil film filler opening, heat will be brought to bearing metal along with the oil heated up, the toughness of bearing can be made like this to reduce, and wear intensity strengthens.Therefore, in order to energy efficiency, research fuel-saving type bearing is the problem that current bearing manufacturer both at home and abroad generally faces.
Model utility content
The purpose of this utility model is the fuel supply flow rate in order to reduce watt sliding bearing lubricating, proposes fuel-saving type part watt sliding bearing.
Fuel-saving type part watt sliding bearing described in the utility model, it comprises part watt sliding bearing body; A described part watt sliding bearing body comprises housing filler opening, oil film filler opening, bearing shell body filler opening, bearing metal, bearing shell body and two housings; The plane that two housings of described part watt sliding bearing body connect is called horizontal flange; Described bearing metal is positioned at inside bearing shell body, and bearing metal and bearing shell body are hollow cylinder; Described oil film filler opening is positioned at bearing metal internal surface; Described bearing shell body filler opening is positioned at bearing shell external surface;
Described oil film filler opening is α with the part line of watt sliding bearing body central and the angle of horizontal flange, and described oil film filler opening is positioned at side, horizontal flange counter-rotating direction with the line of part watt sliding bearing body central; Described α≤25 °, and α >=15 °;
Described bearing shell body filler opening is β with the part line of watt sliding bearing body central and the angle of horizontal flange, and described bearing shell body filler opening is positioned at side, horizontal flange counter-rotating direction with the line of part watt sliding bearing body central; Described β≤25 °, and β >=15 °;
Passage between described housing filler opening and force feed film entrance is positioned at bearing metal outer surface; Oil inlet passage between described bearing shell body filler opening and oil film filler opening is cylindrical.
The beneficial effects of the utility model suitable have selected oil-feed angle, decrease the leakage of cold oil, also block the oil heated up and come back to oil inlet passage, therefore, reach the effective temperature-reducing of bearing metal, and then reaching the object reducing bearing fuel supply flow rate, fuel-saving type part watt sliding bearing described in the utility model can save the bearing lubrication oil mass of 36% under identical bearing oil temperature condition.
