Abstract

The utility model relates to a lubricant circuit of a tilting pad sliding bearing. The bearing is a tilting pad sliding bearing, a bearing body is arranged outside tilting pads, and the two sides of the bearing body are provided with an end cover for the bearing. The lubricant circuit is characterized in that the bearing is directly lubricated, i.e. a lubricant nozzle is arranged between adjacent pads of the bearing, and the upper end of the bearing body is provided with an oil return port for oil returning. Due to the direct lubrication and the arrangement of the inlet of the oil return channel on the upper end of the bearing, the utility model integrates the advantages of direct lubrication and oil bath lubrication, abandons the shortcomings thereof, and not only solves the problem of tile kilning with insufficient oil during the direct lubrication, but also solves the problem that the temperature rise of the oil bath lubrication is higher than the temperature rise of the direct lubrication. The whole lubricant circuit of the bearing has the advantages of simple design and convenient manufacture.

Description

A kind of lubricating oil path of tilting pad sliding bearing

Technical field

The utility model relates to the sliding bearing technical field, the concrete lubricating oil path that relates to a kind of tilting pad sliding bearing, and this oil circuit can directly be lubricated bearing, and oil-poor phenomenon can not occur.

Background technique

The existing watt sliding bearing that can incline has flooding system lubrication and directly lubricated two kinds of lubricating systems, fuel-displaced how the outflow from bearing (ball) cover axle side clearance, bottom or top.

Bearing adopts directly lubricated, and can make cold oil enter bearing shell rapidly, and stop too much deep fat to enter bearing shell, thus the temperature of reduction bearing shell and axle journal.When directly lubricated, lubricant oil promptly flows out bearing, and no immersion oil phenomenon is if the lubricant oil oil mass is calculated incorrect or because of other reason causes the fuel feeding deficiency, can be caused oil-poor and tile kilning.When bearing adopted flooding system lubrication, flooding system lubrication can be full of by the inner fluid of bearing, avoids oil-poor tile kilning.The flooding system lubrication oil return is many flows out from the end cap bottom opening, guarantee that the inner fluid of bearing is full of, and needs the number or the size of control spill port, and difficulty relatively during design is simultaneously with directly lubricated to compare bearing temperature rise higher.

The model utility content

Technical problem to be solved in the utility model is, overcome problems of the prior art, a kind of lubricating oil path of tilting pad sliding bearing is provided, combine the advantage of directly lubricated and flooding system lubrication, promptly solved the directly lubricated oil-poor tile kilning that may occur, solved the problem of flooding system lubrication again than directly lubricated temperature rise.

In order to address the above problem the technical solution of the utility model is such:

A kind of lubricating oil path of tilting pad sliding bearing, bearing are the tilting pad sliding bearing, and the tile fragment outside is a bearing support, the bearing support both sides are the end cap of bearing, it is characterized in that bearing adopts directly lubricated, promptly between the every adjacent tile fragment of bearing, be provided with the lubricant oil nozzle; Be provided with the return opening that is used for oil return in the upper end of bearing support.

Described bearing support is provided with the oil return oil duct that oil return is drawn from side or bottom that is communicated with return opening.

Described end cap is provided with the oil return oil duct that oil return is drawn from side or bottom that is communicated with return opening.

Beneficial effect, directly lubricated and oil return oil duct entry design has been taken into account the advantage of directly lubricated and flooding system lubrication in the upper end of bearing, has abandoned its shortcoming, promptly solved the directly lubricated oil-poor tile kilning that may occur, solved the problem of flooding system lubrication again than directly lubricated temperature rise.The simplicity of design of whole bearing lubricating oil circuit, easily manufactured.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1-Fig. 2

Relate to a kind of can the employing directly in the present embodiment and lubricate, can not occur the bearing lubrication mode of oil-poor phenomenon again.Described bearing is the tilting pad sliding bearing, and tile fragment 1 outside is a bearing support 2, and the bearing support both sides are the end cap 3 of bearing.

Bearing adopts directly lubricated, promptly is provided with lubricant oil nozzle 4 between the every adjacent tile fragment 1 of bearing, and 5 designs of scavenge oil hydraulic fluid port are in the upper end of bearing support 2.Adopt directly and lubricate, can make cold oil enter into bearing shell rapidly, and can stop too much deep fat to enter bearing shell, thus the temperature of reduction bearing shell and journal surface.

5 designs of scavenge oil hydraulic fluid port can guarantee that in the upper end of bearing the inner fluid of bearing is full of, and prevent that bearing is oil-poor, flow out big that bearing can design the oil return oil duct rapidly for making fluid.Bearing adopts oil spout and goes up the lubricating system of oil return, combines the advantage of directly lubricated and flooding system lubrication, has promptly solved the directly lubricated oil-poor tile kilning that may occur, and has solved the problem of flooding system lubrication than directly lubricated temperature rise again.

When oil return circuit designed, bearing adopted directly and lubricates, and nozzle promptly is installed on bearing support, with the entry design of the oil return oil duct of the bearing upper end at bearing.

Referring to Fig. 3-Fig. 6, when design bearing, require bearing sometimes in the lower end oil return, only need this moment milling oil return oil groove 6 on the bearing support 2 of bearing or on the end cap 3, lubricant oil is caused the lower end outflow of bearing gets final product; Sometimes require bearing only to need at this moment on the bearing support 2 of bearing, to bore spill port 7, a side lubricant oil is caused that the opposite side of bearing gets final product in a side oil return.

More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
