Description
Technical Field
The invention relates to the field of seat type sliding bearing cooling, in particular to a seat type sliding bearing cooling mechanism.
Background
The seat type sliding bearing has a central height limitation in the use process, and when the bearing load of the shaft is increased, the generated heat is increased, and the loss is increased, the cooling requirement on oil is also increased. The oil cooler of the seat type sliding bearing in the prior art is a cylindrical cooler, and a plurality of axial cooling copper pipes are arranged inside the oil cooler in a penetrating mode. When the need for oil cooling increases, the need for increased heat exchange capacity and increased cooling effectiveness of the oil cooler typically includes increased copper tube cooling area, increased number of copper tubes, etc., all of which require increased diameter and larger footprint of the cylindrical cooler. However, in the prior art, the oil cooler is installed in the bearing chamber, after the load is increased, the outer diameter of the bearing bush corresponding to the bearing action needs to be increased in the same ratio, but the space of the bearing chamber is fixed, and other parts in the bearing chamber need to be installed and maintained, so that the space for installing the oil cooler below the central line of the inner shaft of the bearing chamber is narrower, the oil cooler is not allowed to be increased in size at all, and the efficient and reliable oil cooling action cannot be provided.
Disclosure of Invention
The invention aims to provide a seat type sliding bearing cooling mechanism to solve the problem that an oil cooler in the prior art cannot provide reliable oil cooling effect after bearing load is increased.
In order to achieve the purpose, the basic technical scheme of the invention is as follows: a seat type sliding bearing cooling mechanism comprises a bearing loading seat and a cooler, wherein the cooler is in a flat cuboid shape and comprises a left end plate, a right end plate, an upper panel and a lower panel, a rectangular loading box is arranged on the bearing loading seat, the cooler is inserted in the loading box, and a plurality of cooling copper pipes are arranged in the cooler.
The principle and the advantages of the scheme are as follows: during practical application, the bearing loads the base of loading as slide bearing of seat, the cooler provides heat exchange cooling for slide bearing's lubricating oil, the structure that adopts flat cuboid form has reduced the occupation of vertical space, when the axle bush of bigger external diameter is adopted in the load increase, such cooler can be more abundant utilize the cooling that lubricating oil was carried out in the bearing indoor constrictive space, it is littleer to the occupation demand in space to compare prior art's cylindrical cooler, can be more constrictive, provide bigger heat exchange cooling efficiency in the flat space, guarantee still can guarantee the effective cooling of lubricating oil under the condition of load increase, ensure slide bearing's reliable and stable work.
