Abstract

The invention relates to a split bearing bush seat type sliding bearing tank, which comprises a tank body connected with a casing, a sliding bearing component and a rolling bearing component which are arranged in the tank body and used for supporting a shaft,; the sliding bearing component comprises a bearing bush, an oil ring and a bearing bush installation seat; the rolling bearing is a single four-point contact ball bearing; and a gravity support surface between the tank body and the casing is positioned at the lower part of the sliding bearing component. According to the invention, the technical problems of large volume, large weight and large bending moment of the current sliding bearing tank can be solved, the weight of the bearing tank can be reduced, the capacity of the lubricating oil can be raised, and the installation of the sliding bearing tank is more stable and reliable.

Description

technical field [0001] The invention relates to a sliding bearing box. Background technique [0002] The bearing housings of existing pumps, motors, and gearboxes sometimes need to use sliding bearing housings. The bearing pad mounting seat in the sliding bearing housing is one piece, and the whole is processed into a spherical surface to install the bearing pads. This structure has the advantages of simple structure and processing. The disadvantage is that the box is heavy and the effective volume of the oil pool is small. [0003] In addition, double row angular contact ball bearings are generally used in the sliding bearing box to bear the axial force. However, double-row angular contact ball bearings generate a lot of heat and are inconvenient to lubricate and cool, and have a large structural mass, complex structure, and inconvenient use and maintenance. [0004] In addition, in order to prevent the outer ring of the axial force bearing from rotating, the sliding bear...
