Background technique
In prior art, Hydrodynamic thrust-bearing is mainly comprised of rotating shaft, runner plate, bearing shell and bearing support, rotating shaft is fixedly connected with runner plate for driving runner plate to rotate, and bearing shell is a plurality of, is distributed on rotating shaft surrounding, and bearing shell is inclined at the working surface below of runner plate, and clockwise to forming wedge gap with runner plate, large mouthful of side of wedge gap is oil inlet end, the osculum side of wedge gap is oil outlet end, bearing support is fixed in oil groove, and is connected with bearing shell.During use, cold oil large mouthful of side from wedge gap under the drive of mirror rotation runner plate enters, and goes out, and between runner plate working surface and bearing shell working surface, be formed for the oil film of bearing load from the osculum effluent of wedge gap.But in adjacent two bearing shells, because the oil outlet end of last bearing shell is the oil inlet end of a rear bearing shell, and oil is in meeting heating after runner plate friction, this just causes having part deep fat and is attached to runner plate working surface, and under the drive of runner plate, enter between next bearing shell and runner plate, correspondingly reduced the cold oil amount that enters bearing shell, not only improved the working oil temperature of bearing, the bearing capacity that has reduced bearing, also easily causes damage to bearing shell.In addition, in actual use, conventionally a bearing shell after adopting the distance increasing between two bearing shells to avoid the deep fat of last bearing shell to enter, but which has correspondingly increased the volume of thrust-bearing, not only cause the space hold area of thrust-bearing to increase, also cause the manufactured materials of whole thrust-bearing to increase, cost is higher.
Model utility content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of Hydrodynamic thrust-bearing is provided, the utility model not only can reduce the volume of whole thrust-bearing, can also reduce the deep fat amount that enters bearing shell, and increase the cold oil amount that enters bearing shell, reach the object that improves bearing load carrying capacity.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of Hydrodynamic thrust-bearing, it is characterized in that: between adjacent two bearing shells, be provided with oil-isolating device, described oil-isolating device comprises flexible oil separating plate and supporting frame, support frame as described above is fixed in oil groove, described flexible oil separating plate bottom is fixedly connected with supporting frame, and top coordinates with runner plate and stops that the deep fat that is attached to runner plate working surface enters next bearing shell.
Described flexible oil separating plate comprises supporting section and flexible oil removal section, and described supporting section is connected with supporting frame, and described flexible oil removal section coordinates oil removal with runner plate.
Between described flexible oil removal section and runner plate, there is the gap that is less than 5mm.
Support frame as described above is fixed on oil groove bottom or is fixed on the bearing shell of large mouthful of side of wedge gap, and when supporting frame is fixed on the bearing shell of large mouthful of side of wedge gap, supporting frame is connected with bearing shell by link, and has oil inlet passage between supporting frame and bearing shell.
Employing the utility model has the advantage of:
One, in the utility model, by flexible oil separating plate, can stop that the deep fat that is attached to runner plate working surface transmits between adjacent two bearing shells, when minimizing enters the deep fat amount of bearing shell, can increase the cold oil amount that enters bearing shell, not only be conducive to reduce the working oil temperature of bearing, also help the oil slick thickness increasing between runner plate and bearing shell and the bearing capacity that improves bearing.And, because adopting flexible material, makes oil separating plate, when ensuring better oil removal effect, can also reduce the frictional loss of flexible oil separating plate, be conducive to improve the working life of flexible oil separating plate.In addition, compare with Hydrodynamic thrust-bearing of the prior art, due to the utility model can prevent deep fat that last bearing shell flows out under the drive of runner plate, enter after a bearing shell, therefore can also reduce the distance between adjacent two bearing shells, thereby can reduce on the whole the volume of thrust-bearing, both be conducive to reduce the space hold area of thrust-bearing, be conducive to again reduce the manufacture cost of thrust-bearing.
Two, in the utility model, the structure that described oil separating plate is mainly comprised of supporting section and flexible oil removal section, be conducive to improve the stability of whole oil separating plate, and, in oil removal process, flexible oil removal section can tilt along with runner plate sense of rotation, is conducive to strengthen the oil removal dynamics of oil separating plate, improves oil removal effect.
Three, in the utility model, between described flexible oil removal section and runner plate, there is the gap that is less than 5mm, this structure can either reduce the deep fat amount that last bearing shell enters a rear bearing shell, can reduce again flexible oil removal section wear rate, the working life that is conducive to improve flexible oil removal section.
Four, in the utility model, supporting frame both can be fixed on oil groove bottom, also can be fixed on the oil-feed side of bearing shell, make the easier for installation of whole oil-isolating device, in addition, oil separating plate coordinates with runner plate and stops that the deep fat that is attached to runner plate working surface enters next bearing shell under the support of supporting frame, and the stability while also making oil separating plate work is better, is conducive to improve oil removal effect.
