Abstract
The utility model discloses an improved water pump bearing lubrication structure. The improved water pump bearing lubrication structure comprises a bearing cover and a bearing, wherein the bearing cover and the bearing are both fixed to a water pump body. An inner ring of the bearing is fixed to a water pump shaft. The bearing cover covers the bearing from outside. A cavity is formed in the bearing cover. The inner diameter of the cavity is larger than the outer diameter of the inner ring of the bearing. An oiling channel is formed on the bearing cover and penetrates through the cavity wall of the cavity. A grease stop ring is located in the cavity and fixed to the portion, arranged outside the bearing, of the water pump shaft. A circumferential flange is arranged on the outer wall of one end, opposite to the bearing, of the grease stop ring. The outer diameter of the flange is matched with the inner diameter of the cavity. An annular gap is formed between the outer wall of the grease stop ring and the corresponding inner wall of the cavity. Due to the annular gap, the oiling channel is communicated with the space between the inner ring and an outer ring of the bearing. Therefore, grease poured from the oiling channel can directly reach a rolling element of the bearing, the rolling element of the bearing can be enough lubricated, and the user effect of the grease is improved.
