Abstract

The invention relates to the technical field of bearings, and discloses a bearing supporting device. The bearing supporting device comprises a bearing body, an upper bearing bush, a lower bearing bush, housing structures and oil throwing devices, wherein the upper bearing bush and the lower bearing bush are connected. The bearing body is provided with a first penetration hole, the upper bearing bush and the lower bearing bush are arranged in the first penetration hole, a rotation shaft can penetrate through the part between the upper bearing bush and the lower bearing bush, and the bearing body and the upper bearing bush are provided with communication oil inlet holes. The housing structures are arranged on the two sides of the bearing body and matched with the bearing body to form oil cavities, and each oil cavity communicates with an oil outlet hole formed in the bearing body. The oil throwing devices are arranged on the two sides of the upper bearing bush and located in the oil cavities and are connected with the rotation shaft. According to the disclosed bearing supporting device, it is guaranteed that in the rotation shaft running process, fresh lubricating oil with certain pressure constantly lubricates the rotation shaft, the lubricating effect is good, and the rotation shaft bearing capability is improved; and in addition, lubricating oil cooling through cooling water is not needed any more, and the integral structure of the machine is simpler.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing supporting device. Background technique [0002] Bearing is an important part of mechanical equipment, mainly used to support the rotation of the shaft and reduce the deformation and wear of the shaft during the movement. The application fields of the shaft are also quite extensive. For example, in the field of diesel engines, the connecting shaft system of the diesel engine usually includes a thrust shaft, an intermediate shaft, a stern shaft, etc., and the shaft system is long and bears a large load. It can effectively reduce wear and improve the transmission efficiency of the shaft system. [0003] At present, there are two main types of intermediate shaft support devices. One is the intermediate shaft support device using rolling bearings. This device includes bearing housings, bearing covers, bearing outer rings, inner rings, rolling elements, cages, etc., and us...
