Description

A kind of certainly radiating bear box of turbocharger

Technical field

The utility model is related to mechanical equipment technical field, the radiating bear box certainly of specially a kind of turbocharger.

Background technology

Turbocharger is actually a kind of air compressor, increases air inflow by compressed air, its core technology Consist of turbine or compressor, but the rotating speed more than 150000 turns for the maximum speed due to turbocharger, its The bear box holding whole turbocharger plays vital effect, and the bearing arrangement of turbocharger is related to turbine work The reliability made and durability problem.Turbo-charger bearing is broadly divided into two classes, and a class is floating bearing（The ripple department axle being commonly called as Hold）, another kind of is then ball bearing, and because the temperature and pressure when compression of turbine gasoline engine and burning all can increase, detonation is inclined To increasing, under whole turbocharger intensive work, the cooling system load of turbocharger itself serious it is impossible to Meet the cooling requirements under high intensity turbocharger operation.

Utility model content

The purpose of this utility model is to provide a kind of radiating bear box certainly of turbocharger, to solve above-mentioned background Propose in technology under whole turbocharger intensive work, the cooling system load of turbocharger itself is serious, no Method meets the problem of the cooling requirements under high intensity turbocharger operation.

For achieving the above object, the utility model provides following technical scheme：A kind of certainly radiating bearing of turbocharger Housing, including water tank, water cooling equipment, fuel feed hole, spreader groove, thrust bearing, axle bed, jump ring, gear plate, volute, roller assembly, Floating bearing, exhaust apparatus, booster shaft, bearing holder (housing, cover) and gas off-take, described water tank is connected with fuel feed hole by water cooling equipment, And the lower section of fuel feed hole is provided with spreader groove, the two ends of described thrust bearing are fixed with booster shaft, the inside edge of described axle bed It is embedded with jump ring, and the right-hand member of jump ring is connected with gear plate, the surface inserting of described volute has roller assembly, described floating bearing Lower section is provided with exhaust apparatus, and the right-hand member of described booster shaft is fixed with axle bed, and the lower section of described bearing holder (housing, cover) is provided with gas off-take.

Preferably, the surrounding of described spreader groove is provided with block activity oil baffle.

Preferably, the outer ring body diameter of described jump ring is less than the interior diametrically 1mm of gear plate.

Preferably, described roller assembly and its overcoat are partial installation structure.

Preferably, described exhaust apparatus profile be designed as funnel-shaped.

Compared with prior art, the beneficial effects of the utility model are：Certainly the radiating bear box of this turbocharger sets There is water tank, sustainable water inlet puts into is lowered the temperature to water cooling equipment, because it is closer to apart from oil-in, can be fast quickly Oil-in is acted on, whole turbocharger is effectively lowered the temperature, exhaust apparatus can be by inside turbocharger High-temperature gas discharge, when turbine wheel shaft runs up, control turbine wheel shaft dynamic stability, this turbocharger from radiating axle Hold housing to have from radiating effect, and compact conformation, frictional force is less, and the effect of turbo lag is lower, the pressure to the power limit Squeeze more favourable, being dynamically controlled to turbine wheel shaft effectively, meet the radiating under high intensity turbocharger operation Require.
