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 with oil-isolating device 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 with oil-isolating device, comprise runner plate and a plurality of bearing shells that are arranged on runner plate below, it is characterized in that: described oil-isolating device is fixedly installed in the oil groove between adjacent two bearing shells, described oil-isolating device comprises oil separating plate and supporting frame, support frame as described above is fixed in oil groove, the bottom of described oil separating plate is connected with supporting frame elasticity, and top coordinates with runner plate and stops that the deep fat that is attached to runner plate working surface enters next bearing shell.
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.
Described oil separating plate is connected with supporting frame by spring.
The quantity of described spring is many, and many springs are arranged between oil separating plate and supporting frame.
Employing the utility model has the advantage of:
One, in the utility model, by 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.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, 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.
Three, in the utility model, described oil separating plate is connected with supporting frame by spring, by spring, can automatically regulate the dynamics that contacts between oil separating plate and runner plate, even if oil separating plate is used and exists for a long time in the situation of certain wearing and tearing, also can guarantee oil removal effect, be conducive to extend the working life of whole oil-isolating device; In addition, this structure, ensuring under the prerequisite of better oil removal effect, also can not affect the rotation of runner plate.
Four, in the utility model, the quantity of described spring is many, many springs are arranged between oil separating plate and supporting frame, this structure had both made the stability of oil separating plate on supporting frame better, make again in oil separating plate working surface (oil removal face) each position more balanced with the contact dynamics of runner plate, can further improve oil removal effect, thereby further reduce the volume of whole thrust-bearing.
