Abstract
The utility model provides a kind of high-efficiency operation turbosupercharger, the turbo-side collar extension of the intermediate in its rotor shaft and formation spindle oil chamber is through being sealed and matched, between intermediate and turbine, be provided with thermal shield, the rotor shaft axle root place at thermal shield axle perforation place is provided with elastic packing outer shroud one.The heat-blocking action that elastic packing outer shroud in the technical program is equivalent to thermal shield radially extends to rotor shaft, guarantee the service behaviour of the interior ring of elastic packing and rotor shaft, improve the working efficiency of pressurized machine itself, motor, also greatly extended pressurized machine working life.
Description
Technical field
The utility model relates to automobile turbo-supercharger, relate in particular to turbocharger rotor axle axle head cooperating structure.
Background technique
Automobile turbo-supercharger is ultra high speed works assembly, and turbine end is in hot environment, and that rotor shaft immerses is lubricated in the lubricant medium of intermediate, be cooled, and has good shaft end seal simultaneously, maintains normal work running.In existing product structure, the elastic sealing ring that adopts one rotary seal to coordinate on the turbo-side axle head of rotor shaft, but it is not long-time after installing and using, normally 5 ~ 7 months, disassemble the turbosupercharger going wrong, often on the rotor shaft pillow block of discovery turbo-side, normal appearance becomes blue, so that carbon deposit and local blackout phenomenon, and carbon deposit is in the time of closure gasket groove, elastic sealing ring can close kayser on rotor shaft because of carbon deposit Jiao, with the common High Rotation Speed of axle, cause intermediate collar extension by heavy wear, further aggravate the pernicious process that rotor shaft sealing ability lost efficacy, also cause rotor shaft not reach rated revolution running, efficiency of turbocharger reduces rapidly, engine power significantly declines, even cause the technical problems such as parking.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of high-efficiency operation turbosupercharger of still guaranteeing rotor shaft good operation ability and shaft sealing performance in high speed and hot operation state.The high-efficiency operation technology for Turbocharger Manufacturing scheme that the utility model provides, its main technical content is: a kind of high-efficiency operation turbosupercharger, rotor shaft encircles and is sealed and matched in elastic packing with the turbo-side collar extension of the intermediate that forms spindle oil chamber, between intermediate and the turbine wheel back of the body, be provided with thermal shield, the rotor shaft axle root place at thermal shield axle perforation place is provided with elastic packing outer shroud one.
In above-mentioned overall technical architecture, the elastic ring collar extension of ring and the elastic packing outer shroud 180 ° of settings that are radially staggered in described elastic packing.
The disclosed high-efficiency operation technology for Turbocharger Manufacturing of the utility model scheme, the elastic packing outer shroud that rotor shaft is set up through the axle root of thermal shield, effectively having blocked turbine end heat is conducted by thermal shield axis hole, the heat conduction of ring and roller axle inner segment in invasion and attack elastic packing, ensure rotor shaft continue in good lubricated environment, lubricant oil can be waved good lubrication and cooling effect to environment-development in rotor shaft and elastic packing really, thereby guarantee that in elastic packing, ring can be given full play to the sealability that its Technology design requires, ensure that lubricant oil does not leak to turbo-side, the described technical problem of prior art generation and the generation of phenomenon are avoided, moreover in the elastic packing outer shroud of increase and elastic packing, ring forms labyrinth sealing structure, has greatly strengthened sealing effect simultaneously.Comprehensive, the elastic packing outer shroud increasing in the technical program is equivalent to the heat-blocking action of thermal shield to rotor shaft extension radially, guarantee the service behaviour of the interior ring of elastic packing and rotor shaft, improve the working efficiency of pressurized machine itself, motor, make the certain assistance of arranging of pressurized machine bring into play engine operation efficiency, also greatly extended pressurized machine working life.
Brief description of the drawings
Fig. 1 is general assembly sectional structure chart of the present utility model.
Fig. 2 is the A partial enlarged drawing of Fig. 1.
Embodiment
The disclosed high-efficiency operation turbosupercharger of the utility model, rotor shaft 1 rotates and is arranged on intermediate 2, and intermediate 2 inner chambers form the oil lubrication chamber of rotor shaft 1.Rotor shaft 1 one end arranges turbine 4, the other end arranges aerostatic press impeller, intermediate 2 and turbine 4 are taken turns and between the back of the body, are provided with the thermal shield 5 that rotor shaft 1 and intermediate 2 is isolated to turbine case space, the intermediate collar extension of rotor shaft 1 and turbo-side through together with resilient sealing ring sealing coordinate, in this programme structure Zhong Chenggai road, sealing is referred to as to encircle 6 in elastic packing.The rotor shaft 1 axle root at the axle perforation place of thermal shield 5 is provided with another road elastic sealing ring, is referred to as elastic packing outer shroud 7 in this programme structure.Described elastic packing outer shroud 7 preferably adopts the high speed steel material that hardness is high.As shown in Figure 2, elastic packing outer shroud 7 has been blocked the pathway of turbine end heat by the gap between thermal shield axis hole and rotor shaft, turbo-side high temperature is isolated from outside elastic packing outer shroud 7, thereby it is effectively lubricated and cooling fully to guarantee that the interior ring 6 of elastic packing and rotor shaft 1 can obtain in lubricant oil environment.
Claims (2)
1. a high-efficiency operation turbosupercharger, rotor shaft (1) encircles and is sealed and matched in elastic packing with the turbo-side collar extension of the intermediate (2) that forms spindle oil chamber, between intermediate and the turbine wheel back of the body, be provided with thermal shield (5), it is characterized in that rotor shaft (1) the axle root place at thermal shield (5) axle perforation place is provided with one elastic packing outer shroud (7).
2. high-efficiency operation turbosupercharger according to claim 1, is characterized in that in described elastic packing the 180 ° of settings that are radially staggered of the elastic ring opening of ring and elastic packing outer shroud.
