Abstract
The invention relates to a Dongfeng series internal combustion locomotive supercharger thrust bearing, oil wedge surfaces and planes thereof are all distributed in a fan shape on the end surface of the thrust bearing, the oil wedge surface is larger than a connected plane, and an oil groove is positioned at the start edge of each oil wedge surface. A small oil groove is drilled at the outer circumference of the oil groove, and an oil baffle edge is arranged at the outer circumference of each oil wedge surface. Both end surfaces of the thrust bearing are connected with the oil wedge surfaces on the end surfaces through an inclined semi-hole oil groove on an inside diameter. The fan-shaped oil wedge surface has a large oil film loaded area and a long oil film path, the bearing capability is improved by more than 60 percent than the existing oil wedge surface, and the oil baffle edges on the outer circumference surfaces of the oil wedge surfaces can delay the outflow of lubricating oil, thereby being helpful for forming oil film force. The small oil grooves arranged on the oil grooves can discharge impurity granules carried in the lubricating oil, and both end surfaces of the thrust bearing are connected through the inclined semi-hole oil groove, so that no wear traces are formed on the surface of the thrust bearing and the bearing capacity of the thrust bearing is improved.
Description
Technical field the present invention relates to a kind of Dongfeng series internal combustion locomotive supercharger thrust bearing, belongs to supercharger rotor bearing arrangement technical field.
Background technique is in Dongfeng series internal combustion locomotive supercharger, pressurized machine is made up of gas compressor and turbo machine, compressor impeller and turbine disk cantilever are at the two ends of main shaft, and rotor main shaft is supported by two radial bearings, and thrust-bearing is born the end thrust from turbine end.All there is oil film wedge on the thrust-bearing two sides, and during the pressurized machine rotation, thrust-bearing is also rotating.The thrust-bearing bearing load is the several times of radial bearing bearing load, and therefore, general pressurized machine damage of bearings is that thrust-bearing damages earlier substantially.So whether abundance directly influences the reliability of thrust-bearing utilization for the bearing capacity of thrust-bearing and lubricating oil supply, and then influences the working life of pressurized machine.In prior art, supercharger thrust bearing has 8 oil film wedge faces and 8 oil grooves, two limits of oil film wedge face are parallel, oil groove is positioned at the centre of oil film wedge face, the oil film wedge degree of depth only changes to some extent at circumferencial direction, the oil film wedge of this form only can form the bearing capacity of oil film in one direction when forming squeeze film, bearing capacity is less.In addition, two of thrust-bearing end face lubricating oil supplies are the through holes of the diameter 2mm in leaning on oil groove.The thrust-bearing of this structure is less because of bearing capacity, and the lubricating oil of oil film wedge face because centrifugal force has been got rid of soon, can not accumulate oil in the thrust-bearing rotation.Thrust-bearing just is subjected to the influence of lubricating oil supply easily in utilization like this, and thrust-bearing is in case damage is pushed compressor impeller to impeller cover from the axial force that turbine end is powerful, the two is rubbed mutually, cause compressor impeller to damage, and then pressurized machine is quit work, break down.
Summary of the invention is for overcoming the existing in prior technology problem, the purpose of Dongfeng series internal combustion locomotive supercharger thrust bearing of the present invention is: for Dongfeng series internal combustion locomotive supercharger provides a kind of novel thrust-bearing, improve the thrust-bearing bearing capacity, improve the bearing lubrication state, reduce the pressurized machine rate of fault, guarantee that the Dongfeng series internal combustion locomotive supercharger application safety is reliable.
The technological scheme of Dongfeng series internal combustion locomotive supercharger thrust bearing of the present invention is: adopt novel thrust-bearing oil film wedge face area and area of plane ratio, oil groove position, oil film wedge face area greater than the coupled area of plane, oil groove is at the initial line that rises of oil film wedge face, and it is fan-shaped that oil film wedge face and plane all are.Outer circumference place has little oil groove on the oil groove.Secondly, added an oil retaining edge at oil film wedge face excircle, inner radius processes half hole oil groove of several angle.
This Dongfeng series internal combustion locomotive supercharger thrust bearing, oil film wedge face and its plane are fan-shaped and are distributed on the thrust-bearing end face, and oil film wedge face area is greater than the coupled area of plane, and oil groove is positioned at the initial line that rises of oil film wedge face.The excircle place of oil groove has little oil groove, and the excircle of oil film wedge face is provided with oil retaining edge.Connect both ends of the surface oil film wedge face by one on the internal diameter half oblique hole oil groove between two end faces of thrust-bearing.
Dongfeng series internal combustion locomotive supercharger thrust bearing of the present invention is when design, through big quantitative analysis, calculating and test, Dongfeng series internal combustion locomotive supercharger thrust bearing of the present invention is parallel than the oil film wedge face both sides of existing thrust-bearing, oil groove in the centre of oil film wedge face, oil film wedge face and its area of plane ratio be to compare at 5.5: 4.5, fan-shaped oil film wedge face oil film loaded area at first of the present invention is big, the oil film path length, than the parallel oil film wedge face bearing capacity raising in the both sides of prior art more than 60%.Secondly, oil retaining edge can delay the outflow of lubricating oil on the oil film wedge face outer peripheral surface, helps the formation of oil-film force.The 3rd, the little oil groove of opening on the oil groove can be drained the impurity particle that carries in the lubricating oil, avoids thrust bearing surface to be subjected to the scuffing of impurity, and thrust-bearing is worked in clean lubricating oil medium, improves bearing working life.The 4th, connect both ends of the surface oil film wedge face by half an oblique hole oil groove between two end faces of thrust-bearing, make two end face lubricating oil of thrust-bearing in liberal supply, have more practicability.
Dongfeng series internal combustion locomotive supercharger thrust bearing of the present invention, its positive technique effect is: adopt newly-designed thrust-bearing analyze as calculated with endurance test after, thrust bearing surface is without any wear trace, and the improvement of this structure of thrust-bearing has improved the thrust-bearing bearing capacity.
