Water pump is the machinery for conveying liquid or being pressurized liquid, is had a wide range of applications.The maintenance of water pump is production safety
The important guarantee of progress, and the key that the good lubrication of bearing is water pump to be operated steadily in the long term.Existing water pump, especially IS water
Pump, bearing lubrication is more by the way of oil lubrication.By the parts of bearings of rotation or hang over the band oil ring band on oil and take up
Lubricating oil in bearing housing, it is splashed to each position of bearing and implement sufficiently lubrication, then fall back in fuel tank by again
It is secondary to take up.This mode need to control oil mass, and abrasion occurs in bearing when lubricants capacity is very few, and then cause water pump rotary part to touch
Touch damage.Easily occurs oil leak situation in running, oil leak defect processing process is longer, if defect can not be found in time, seriously
Bearing locking can be caused, burn by, or even cause the heavy damage of the important components such as pump shaft.
To solve the problems, such as oil leak, using grease lubrication mode.Lubricating grease is more sticky, is not easy to trickle, and is running
In be not in seepage, so as to unlubricated matter reduction, be not in because lack lubrication matter missing and caused by bearing damage
Caused by rotatable parts damage, the reliability of water pump operation can be improved.
The Chinese patent of Application No. 201320314129.0 discloses a kind of water pump bearing lubrication improved structure, using profit
Grease lubrication, including the bearing cap and bearing being both secured on water pump body；The inner ring of bearing is fixed on pump shaft；Bearing cap from
The outside of bearing is covered, and bearing cap is provided with cavity, and the internal diameter of the cavity is more than the external diameter of the inner ring of bearing, bearing cap
Top is provided with the oiling passage of the cavity wall through cavity, and gear alicyclic ring is located on the pump shaft in the outside that cavity is interior, is fixed on bearing,
Peripheral flange is set on the outer wall of the gear alicyclic ring that one end relative with bearing, the external diameter of flange is adapted with the internal diameter of cavity,
Keep off alicyclic ring outer wall and cavity respective inner walls between form annular gap, the annular gap by oiling passage and bearing,
Space connection between outer ring.But in this technology, if the flange of gear finger ring and cavity inner wall sealing are bad, lubricating grease is easily from sky
Gap is overflowed, and produces leakage.
In view of this it is special to propose the utility model.
