External lubricating device of water pump double-row angular contact ball bearing

The invention provides an external lubricating device of a water pump double-row angular contact ball bearing, and relates to the technical field of bearing lubrication. One end of the power driving mechanism is connected with the holding rod; the top of the rotary pushing assembly is connected with a power driving mechanism; one end of the lubricating oil bearing mechanism is fixedly connected with the holding rod; the oil outlet distance control assembly is installed in the lubricating oil bearing mechanism. One end of the oil outlet device is fixedly communicated with the lubricating oil bearing mechanism; the problems that a traditional bearing smearing rod is poor in smearing uniformity and low in smearing efficiency, the outer side of a bearing needs to be frequently rotated, and the smearing process is troublesome are solved. The bearing can be controlled to rotate automatically, time and labor are saved, the oil port assembly is matched to discharge oil uniformly and smear oil uniformly while the bear
