Description
Technical field
The utility model is related to a kind of auto pump, the positioning lubrication dress of more particularly to a kind of auto pump shaft connecting bearing
Put.
Background technology
The principle of auto pump is that engine drives cold in water pump bearing and wheel rotation, water pump by belt pulley
But liquid is driven by impeller and rotated together, and the edge of water pump cover is thrown toward under the influence of centrifugal force, while producing certain pressure
Power, then flows out from water outlet or water pipe.The center of impeller due to coolant is thrown out of and pressure is reduced, the cooling in water tank
Liquid is inhaled into impeller under unit fixed on water pump suction and the differential pressure action of impeller central through water pipe, realizes the reciprocation cycle of coolant.
The cooling system of Modern Automobile Engine typically all uses centrifugal water pump.Auto pump is automobile engine cooling
The core component of system, its maintainability directly influences the normal work of engine.Auto pump is directly by skin
Band is connected on engine power output shaft to obtain power, that is, does power source with the power of engine itself.In vapour
In the cylinder body of car engine, there is the water channel of a plurality of Cooling Water circulation, lead to the radiator (being commonly called as water tank) that is placed in automotive front
Cross water pipe to be connected, constitute a big water circulation system, in the upper water-out mouthful of engine, equipped with a water pump, pass through fan
Belt drives, and the hot water in engine cylinder-body water channel is pumped out, cold water is pumped into.There is a section temperature on the side of water pump
Device, when automobile just starts when (cold car), does not open, makes cooling water without water tank, only (is commonly called as small follow in engine interior circulation
Ring), when the temperature of engine reaches more than 95 degree, turn on, in-engine hot water is pumped to water tank, during automobile front driving
Cold wind blows over water tank, takes away heat.Engine drives the coolant quilt in water pump bearing and wheel rotation, water pump by belt pulley
Impeller drives to be rotated together, and the edge of water pump cover is thrown toward under the influence of centrifugal force, while producing certain pressure, then
Flowed out from water outlet or water pipe.The center of impeller due to coolant is thrown out of and pressure is reduced, the coolant in water tank is in water
It is inhaled under the differential pressure action of pump inlet and impeller central through water pipe in impeller, realizes the reciprocation cycle of coolant.
Auto pump generally comprises water pump shell, shaft connecting bearing, impeller, band wheel assembly, water seal assembly etc., outside shaft connecting bearing
Circle is interference fitted in water pump shell, but existing most shaft connecting bearing is not carry out axially position, and belt wheel is total
Into being mounted on the central shaft of shaft connecting bearing, shaft connecting bearing is influenceed by external load, can be occurred in the course of time axial
Play, serious meeting makes water seal assembly failure, causes the leakage of coolant.With wheel assembly it is fixed in the form of interference fit
On the central shaft of shaft connecting bearing, after integral installation in place, it is difficult to which the bearing on shaft connecting bearing is lubricated, it is used for a long time
Afterwards, lack lubrication to cause bearing heating, abrasion or even scrap, the service life of bearing is influenceed, so as to reduce auto pump
