Abstract
The lubrication balance that the utility model provides coordinates enhancement mode turbosupercharger, the opposite side of its left and right pair of fulcrum floating bearing assembly, between floating bearing and outer back-up ring, be respectively provided with a grease baffle, described grease baffle free floating is engaged between floating bearing and outer back-up ring.The technical program has that lubrication is not delayed, run up lasting dynamic balancing, ensures reliable, efficient, stable, the lasting technological merit maintaining dynamic running matching relationship.
Description
Technical field
The utility model relates to and support the use, realize the automobile turbo-supercharger of motor synergy, low emission.
Background technique
The rotor shaft of turbosupercharger to run up cooperation through floating bearing in hot environment in intermediate, therefore, turbosupercharger introduces pressurized lubrication oil, make floating bearing and thrust in lubricant oil environment, rotor shaft, floating bearing free floating sealed rotational in intermediate is made to coordinate, on the other hand for the position that runs up provides required cooling on the one hand.The lubricating oil flow system of existing turbosupercharger, the be rotatably assorted oil pressure in gap of rotor shaft, floating bearing and intermediate can be caused not enough, especially when running in the season of amblent air temperature sweltering heat or the Motor Vehicle in area, lubricant oil viscosity reduces, the temperature of described dynamic cooperation place will become higher, in addition, when Motor Vehicle operating conditions frequent variations, the oil pressure and the dynamic mated condition that maintain internal component are very easily destroyed, the oil film free suspension mated condition umklappen of described dynamic cooperation position is Mechanical Contact friction, wearing and tearing that can be exceedingly fast and scrapping, cause vehicle parking.
Summary of the invention
Goal of the invention of the present utility model is no matter under which kind of seasonal climate environment or when meeting with the very fast change of which kind of running state, the dynamic position that coordinates, pressurized machine inside can keep good free floating to coordinate the lubrication balance of operative relation to coordinate enhancement mode turbosupercharger.The lubrication balance that the utility model provides coordinates enhancement mode technology for Turbocharger Manufacturing scheme, its main technical content is: a kind of lubrication balance coordinates enhancement mode turbosupercharger, rotor shaft assembly by left and right pair of fulcrum floating bearing assembly rotating support on intermediate bearing saddle bore, the opposite side of left and right pair of fulcrum floating bearing assembly, between floating bearing and outer back-up ring, be respectively provided with a grease baffle, described grease baffle free floating is engaged between floating bearing and outer back-up ring.
Lubrication balance disclosed in the utility model coordinates enhancement mode technology for Turbocharger Manufacturing scheme, the setting of grease baffle makes the part lubricating oil implementing lubrication moderate in floating bearing, rotor shaft assembly, intermediate and thrust place, and do not make them enter intermediate oil back chamber immediately, thus the dynamic cooperation potential energy of pressurized machine inside enough maintains in the oil pressure environment being not less than lubrication supply oil pressure, therefore rotor shaft assembly is made, floating bearing, intermediate and thrust be dynamic coordinates that position is stable to be remained in free floating sealed rotational mated condition, ensure that lubrication is not delayed, dynamic balancing during better maintenance runs up, improve cooling effectiveness and effect simultaneously, can be reliable, efficiently, stable, lasting maintenance dynamic running matching relationship, turbosupercharger obviously extends working life, no matter under what kind of tropical climate, or under which kind of very fast operating mode, power and lasting support can be provided for motor plays synergy function.
Accompanying drawing explanation
Fig. 1 is cut-open view of final assembly of the present utility model.
Fig. 2 is the partial enlarged drawing of the encircled portion of Fig. 1.
Embodiment
Lubrication balance disclosed in the utility model coordinates enhancement mode turbosupercharger, its contexture as shown in the figure, rotor shaft assembly 1 is by left and right pair of fulcrum floating bearing assembly 3,4 rotating support is in the bearing support of intermediate 2, and calm the anger wheel and the turbine at its two ends are arranged at respectively calms the anger in shell and volute.The opposite side of left and right pair of fulcrum floating bearing assembly 3,4, between floating bearing and outer back-up ring, be respectively provided with a grease baffle 8,9, the partial enlargement structure of right floating bearing assembly 4 as shown in Figure 2, grease baffle 9 free floating on described right side is engaged between floating bearing 40 and its outer back-up ring 10, and the grease baffle 8 in left side is full symmetric structure with the grease baffle 9 on right side.Described grease baffle 8, the external diameter of 9 is less than intermediate bearing hole internal diameter, be greater than outer back-up ring hole internal diameter, and form certain interval between intermediate bearing saddle bore, grease baffle 8, the internal diameter of 9 is greater than the axis body diameter of rotor shaft assembly 1, form certain interval between the two, thus be in free floating mated condition when ensureing that rotor shaft assembly runs up, after making lubricant oil carry out intermediate by intermediate oil pipe 5, at floating bearing assembly 3, 4, rotor shaft assembly 1, the dynamic cooperation potential drop speed unhurried current of intermediate 2 and thrust 6, improve the oil pressure of described dynamic cooperation position, ensure to obtain good lubrication between dynamic counterpart, cooling and running balance.
