Description
Technical field
The utility model relates to turbosupercharger, particularly relates to a kind of heat insulation turbosupercharger.
Background technique
The rotor shaft of usual turbosupercharger is by floating bearing supports turbine shaft, turbine shaft is made to be supported on intermediate, its intermediate and impeller be fixedly by arranging a slab, intermediate is connected and fixed by screw and slab, such means of fixation not only installs trouble, and easily produces oil leakage, and the oil duct in present intermediate and water channel are all a kind of vertical linear structure, although also can play cooling action to axostylus axostyle, effect is unsatisfactory.
Model utility content
The purpose of this utility model is to provide a kind of heat insulation turbocharger middle body, has simple, the easy for installation and feature of good heat-insulation effect of structure.
In order to achieve the above object, the technological scheme that the utility model provides is: a kind of heat insulation turbosupercharger, comprise spiral case, described spiral case is provided with intermediate, described intermediate is provided with pressure shell, in described intermediate, turbine shaft is installed, described turbine shaft is separately installed with pressure impeller and turbine, between described turbine and intermediate, thermal-protective coating is installed, described turbine shaft is provided with floating bearing, whirlpool end seal ring is installed between described floating bearing and turbine, extremely impeller is pressed successively thrusting plate to be installed by floating bearing between described floating bearing and pressure impeller, the gentle shrouding of oil baffle.
Between described sealing gland plate and intermediate, seal ring is installed.
Between described floating bearing and intermediate, floating bearing snap ring is installed.
The beneficial effects of the utility model are: the utility model is by comprising spiral case, described spiral case is provided with intermediate, described intermediate is provided with pressure shell, in described intermediate, turbine shaft is installed, described turbine shaft is separately installed with pressure impeller and turbine, between described turbine and intermediate, thermal-protective coating is installed, described turbine shaft is provided with floating bearing, whirlpool end seal ring is installed between described floating bearing and turbine, between described floating bearing and pressure impeller, extremely presses impeller that thrusting plate, the gentle shrouding of oil baffle are installed successively by floating bearing.Thus it is simple, easy for installation and can heat insulation effect to reach structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
