Abstract
The utility model relates to a turbo charger part, concretely relates to novel turbocharger intermediate. The utility model discloses a novel turbocharger intermediate, floats collar bearing no. 1 and sets up at the turbine end including floating collar bearing no. 1 and superficial collar bearing no. 2, floats collar bearing no. 2 and sets up at the compressor end, floats a collar bearing axial width for floating 80~90% of two axial width of collar bearing. The utility model provides a novel turbocharger intermediate, simple structure, easily adjustment can reduce the heating load that the midbody turbine was held, improves the lubrication and the heat dispersion of midbody.
Description
Technical field
The utility model is related to a kind of component of turbo-charger and in particular to a kind of novel turbocharger intermediate.
Background technology
Turbocharger is to promote turbine acting using I. C. engine exhaust energy, increases inlet pressure of internal combustion engines, so that
Power of IC engine improves, and fuel consumption and exhaust pollution reduce." efficiently, energy-conservation, reduction of discharging " is current automobile engine technology
The main target of development, the market demand of turbocharger constantly increases, and booster runs under high speed, high temperature, due to increasing
The depressor temperature too high lubricating oil the leading to fault such as lost efficacy, burn occurs often, has badly influenced stablizing of turbocharger
Run.Therefore, design energy-saving and environmental protection, an efficient turbocharger test platform, be present turbocharger research and development
Important topic.
At present, in the design of existing turbocharger middle body, typically in the turbine side of turbocharger middle body
Floating-ring bearing and compressor side floating-ring bearing axial width equal although such be designed with beneficial to floating-ring bearing processing and
Assembling, but during booster real-world operation, the temperature of turbine end is far above the temperature of generator terminal of calming the anger, the therefore floating ring axle of turbine end
The thermic load held is greater than the floating-ring bearing thermic load of generator terminal of calming the anger, the lubrication needed for therefore at the floating-ring bearing of intermediate both sides
Oil supply amount is also not quite similar.Accordingly, it is considered to different lubrication shapes needed at the floating-ring bearing of turbocharger middle body both sides
Condition, needs to design novel turbocharger intermediate.
Utility model content
The utility model provides a kind of novel turbocharger intermediate, and structure simply it is easy to adjustment, can reduce centre
The thermic load of body turbine end, improves lubrication and the heat dispersion of intermediate.
The technical solution of the utility model is as follows：
A kind of novel turbocharger intermediate, including floating-ring bearing one and floating-ring bearing two, floating-ring bearing one is arranged on
Turbine end, floating-ring bearing two is arranged on generator terminal of calming the anger, floating-ring bearing one axial width be floating-ring bearing two axial width 80～
90%.
Described novel turbocharger intermediate, wherein, floating-ring bearing one is provided with lubricating oil supply point oil circuit one, floating ring
Bearing two is provided with lubricating oil supply point oil circuit two, and lubricating oil supply point oil circuit one diameter is lubricating oil supply point oil circuit two diameter
1.2～1.5 times.
The beneficial effects of the utility model are：Floating-ring bearing two heat of the floating-ring bearing one of turbine side and compressor side
There is larger difference in load, floating-ring bearing one temperature of turbine side is greater than floating-ring bearing two temperature of generator terminal of calming the anger.This reality
It is less than compressor side floating-ring bearing two axial width with floating-ring bearing one axial width of new employing turbo-side, using less
Floating ring width design advantageously reduce friction loss between floating ring, rotating shaft and oil film, thus reduce being produced by oil drag
Raw heat, plays the effect of floating-ring bearing one thermic load reducing turbine side with this.Further, since turbo-side floating-ring bearing
Thermic load at one is higher, adopts larger oil circuit diameter design, more lubrications in the lubricating oil supply point oil circuit one of turbine end
Oily flow flows through the lubricating oil more parts at the floating-ring bearing one of turbo-side, doing work exported by lubricating oil pump and is transported to turbine end
The floating-ring bearing one of side, thus let out to scatter and disappear by lubricating oil end taking away more heats, effectively reduces the temperature of floating-ring bearing one.
Brief description
Fig. 1 is novel turbocharger intermediate structure figure.
Specific embodiment
As shown in figure 1, a kind of novel turbocharger intermediate, including floating-ring bearing 1 and floating-ring bearing 24, floating ring
Bearing 1 is arranged on turbine end, and floating-ring bearing 24 is arranged on generator terminal of calming the anger, and floating-ring bearing 1 axial width is 10mm, floating ring
Bearing 24 axial width is 11mm；Floating-ring bearing 1 is provided with lubricating oil supply point oil circuit 1, and floating-ring bearing 24 is provided with lubrication
Oil supply point oil circuit 22, lubricating oil supply point oil circuit 1 diameter is 0.5mm, and lubricating oil supply point oil circuit 22 diameter is
0.4mm.Lubricating oil, after working connection 1 shunting, divides oil circuit 22 respectively through lubricating oil supply point oil circuit 1 and lubricating oil supply,
To floating-ring bearing 1 and floating-ring bearing 24 feed lubrication.
