Embodiment 1

[0018] like figure 1 As shown, a water pump shaft-connected bearing includes a main shaft 1 and an outer ring 2, a roller 3 is arranged between the main shaft 1 and the outer ring 2, and the two ends of the outer ring 2 and the main shaft main shaft 1 A water seal 4 is arranged between them, and the end of the main shaft 1 adjacent to the inner chamber of the water pump is provided with a water-spinning ring 5 . The water is thrown out by the water ring, thus avoiding the damage of the bearing caused by water entering between the main shaft and the outer ring from the water seal.

Embodiment 2

[0020] like figure 2 and image 3 As shown, the structure of Embodiment 2 is basically the same as that of Embodiment 1, the difference is that the water throwing ring 5 includes an annular body 6, and the inner hole of the annular body is connected with a sleeve that is sleeved outside the main shaft. A barrel 11, the outer surface of the annular body 6 is adjacent to the inner cavity of the water pump and is provided with a radial water groove 7 extending radially.

[0021] The depth of the end of the radial water groove 7 adjacent to the main shaft is greater than the depth of the end of the radial water groove 7 away from the main shaft. This makes it easier for water to be thrown from the radial gutters.

[0022] The annular body 6 is also provided with a conical water-spinning cylinder 8 positioned on the outer surface of the annular body 6, the small end of the conical-shaped water-spinning cylinder 8 is fixedly mounted on the annular body 6, and the conical water-sp...

Abstract

The invention discloses a water pump shaft coupling bearing. The water pump bearing comprises a main shaft and an outer ring. Rollers are arranged between the main shaft and the outer ring, a water seal is arranged between the two ends of the outer ring and the main shaft, and a water splashing ring is arranged at the end, close to the inner cavity of the water pump, of the main shaft; water is splashed out through the water splashing ring, thus the situation that the bearing is broken due to the fact that water enters the position between the main shaft and the outer ring from the water sealis avoided

Description

technical field [0001] The invention relates to a shaft-connected bearing of a water pump. Background technique [0002] In the prior art, the shaft-connected bearing of the water pump prevents the water in the inner cavity of the water pump from entering the bearing through the water seal. During the working process, the water seal is prone to water leakage. It will damage the bearings and cause the pump to malfunction. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a water pump shaft-connected bearing that can effectively avoid bearing damage and prolong the service life of the bearing. [0004] The technical solution of the present invention is: a water pump shaft-connected bearing, including a main shaft and an outer ring, a roller is provided between the main shaft and the outer ring, and a roller is provided between the two ends of the outer ring and the main shaft of the main shaft. There is a wate...
