Abstract

The invention discloses a fan self-lubricating bearing block, and relates to the technical field of bearing blocks. The fan self-lubricating bearing block comprises a hydraulic device, a bearing blockbody, a bearing assembly, a first oil seal, a second oil seal, a lubricating mechanism and a fan, wherein the bearing assembly is formed by stacking a plurality of bearing units from bottom to top. According to the fan self-lubricating bearing block, gaps are formed among the attaching surfaces of the bearing units through the separated bearing assembly so that hydraulic oil can be stored, and the hydraulic oil in the gaps can be mobilized for participating lubrication in time when the bearing units are not lubricated with sufficient hydraulic oil; and through the gaps, during the process ofthe hydraulic oil entering the bearing assembly, the hydraulic oil in the gaps can be driven to swing by the rotation of a connecting shaft, so that the hydraulic oil obtains powerful kinetic energy,the hydraulic oil quickly and fully fills into the gaps of the bearing units for participating the lubricating work in time, and the bearing block is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of bearing housings, in particular to a fan self-lubricating bearing housing and a self-lubricating method. Background technique [0002] Large-scale air handling units must use fans during work. In the existing fan bearing housings, in order to prolong the service life of the bearings and reduce the leakage of lubricating oil and dust pollution to the bearings, oil seals are added to the outside of the bearings to seal the bearings. , The lip edge of the sealing ring will have a certain friction on the transmission shaft. [0003] During the factory assembly process of the fan bearing housing, lubricating oil is usually applied to the oil seal lip in the bearing housing, and no maintenance is required during use. In order to prolong the service life of the bearing, lubricating oil is also applied to the bearing. The high temperature generated during the operation of the machine will melt the lubricating oi...
