Description

A kind of auto pump tooth form pulley assemblies

Technical field

The utility model is related to a kind of auto pump, more particularly to a kind of auto pump tooth form pulley assemblies.

Background technology

The automobile engine of early stage does not have today it is considered that essential important accessory --- water pump, used at that time Liquid cooling medium be pure water, at most mixed with some another name fors, with prevent freeze.The circulation of cooling water fully relies on thermal convection current Natural phenomena.Cooling water is absorbed from cylinder block after heat, just flows up and enter the top of radiator naturally；Cooling water After turning cold, and the bottom of radiator is sunk to naturally and enters the bottom of cylinder block.Can be with using this thermosiphon principle Cooling task is completed reluctantly.But in the near future, water pump is added in a cooling system, to allow cooling water to flow more quickly It is dynamic.

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.

Usual tooth form belt wheel is the power transmission shaft in direct interference connection auto pump, and is not installed with similar fan radiating Mechanism, under the conditions of running at high speed, can cause the radiating effect of the neighboring areas such as water pump shell, belt not good, finally influence automobile The service life of water pump.
