Abstract
The utility model discloses an automatic lubricating device for turbocharger which comprises a rotor shaft of the turbocharger and a pressing shell with a bearing shell. The utility model is characterized in that the pressing shell is connected with an oil storing shell through a locating screw; an oil storing chamber is provided between the pressing shell and the oil storing shell; two ball bearings with out inner rings are provided between the rotor shaft and the bearing shell; an oil seal is installed on one side out of the rotor shaft which is adjacent to a supercharger impeller; a screw plug is arranged on the outboard of the end of the rotor shaft; an oil entering channel and an oil out channel are provided between the oil storing chamber and an oil storing cavity which is formed between the rotor shaft and the bearing shell. The utility model has the advantage of effectively decreasing the abnormal spoilage of the supercharger.
Description
Technical field
The utility model relates to a kind of pressurized machine lubricating fitting.
Background technique
At present, the lubricated engine oil gallery of generally using of turbosupercharger, be subjected to the influence of condition of the engine and behaviour in service because of pressurized machine, make pressurized machine cause improper damage to reach more than 90%, and often dirty because of oil, fuel feeding is not enough, leakage of oil, cause improper damage of pressurized machine and mounting point restricted, need preheating during low temperature.
Summary of the invention
The purpose of this utility model provides a kind of turbosupercharger automatic lubricator, can effectively overcome pressurized machine leakage of oil and improper damage.
The purpose of this utility model is achieved through the following technical solutions, it comprises pressure shell, the store oil shell of turbocharger rotor axle, band cartridge housing, it is characterized in that: this pressure shell links to each other with the store oil shell by positioning screwn, between pressure shell and store oil shell, be provided with the reservoir compartment, between rotor shaft and cartridge housing, be provided with twice and do not have the inner ring ball bearing, side near supercharger impeller outside rotor shaft is equipped with oil sealing, arranged outside has screw plug in the end of rotor shaft, is provided with oil input channel and oil road between rotor shaft and the cartridge housing between formed bearing chamber and the reservoir compartment.
The utility model is owing to adopt technique scheme, and the lubricated employing of pressurized machine is circulating oil path independently, has reduced existingly because of the fuel feeding deficiency, and oil is dirty and cause the improper damage of pressurized machine more than 90%; There is not leakage of oil yet, causes the motor oil starvation to damage thereby reduce because of pressurized machine damages; Overcome the restriction of existing turbosupercharger mounting point in addition, can install arbitrarily; Have reliable at low temperatures characteristics.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure enlarged diagram at B position among Fig. 1.
In the accompanying drawing, 1-supercharger rotor axle, 2-pressurized machine pressure shell, 3-store oil shell, the 4-positioning screwn, 5-reservoir compartment, 6-cartridge housing, 7-ball bearing, the 8-impeller, 9-oil sealing, 10-screw plug, 11-bearing chamber, the 12-oil input channel, 13-oil road, 14, the 15-spring, the 16-blade, 17-damping cushion rubber, 18-overflow valve, the 19-oil drain plug, 20-cushion rubber, 21-bearing outer ring.
Embodiment
That the utility model is described in further detail is as follows below in conjunction with accompanying drawing:
The utility model comprises the pressure shell 2 of turbocharger rotor axle 1, band cartridge housing 6, pressure shell 2 links to each other with store oil shell 3 by positioning screwn 4, between pressure shell 2 and store oil shell 3, be provided with reservoir compartment 5, between rotor shaft 1 and cartridge housing 6, be provided with two no inner ring ball bearings 7, side near supercharger impeller 8 outside rotor shaft 1 is equipped with oil sealing 9, arranged outside has screw plug 10 in the end of rotor shaft 1, is provided with oil input channel 12 and oil road 13 between rotor shaft 1 and the cartridge housing 6 between formed bearing chamber 11 and the reservoir compartment 5.In use, to inject lubricant oil in the bearing chamber 11, lubricant oil circulation in bearing chamber 11 and reservoir compartment 5 by oil input channel 12 and oil road 13, thus bearing 7 is lubricated, because it adopts independent lubricating oil path, therefore overcome the shortcoming of original lubrication system.In order to improve circuit efficient, can on rotor shaft 1, mill out blade 16, to quicken flowing of lubricant oil, the shape of blade can adopt the shape as axial flow pump blade inner or screw thread, and it is better than regular screw threads that it quickens the mobile effect of lubricant oil; For the ease of the installation of no inner ring ball bearing 7, on rotor shaft 1, also be milled with raceway in the bearing, between bearing outer ring 21 and cartridge housing 6, be provided with Returnning spring 14; Oil sealing 9 inboards are provided with Returnning spring 15, can be during greater than inboard spring 15 pressure of oil sealing 9 at bearing chamber 11 inner suctions, oil sealing 9 is opened, air inlet is to reduce oil sealing 9 wearing and tearing, and after suction diminished, oil sealing 9 was closed, so circulation had both guaranteed that lubricant oil was lubricated bearing 7 with the form of mist of oil, reduced simultaneously the wearing and tearing of oil sealing 9 again,, on store oil shell 3, also be provided with overflow valve 18 for inhaled air is discharged; For the ease of changing oil, also be provided with oil drain plug 19 in addition in the lower end of store oil shell 3.In order to prevent leakage of oil, between store oil shell 3 and pressure shell 2, be provided with O-ring seal 20.For reducing the vibrations of bearing 7, be provided with damping cushion rubber 17 between bearing outer ring 21 and the cartridge housing 6.
The utility model can effectively reduce the improper damage of pressurized machine in sum, the reliable and unrestricted characteristics in mounting point under the low temperature.Plate etc. is known technology behind other position structure of turbosupercharger such as turbine, turbine case, the pressurized machine in addition, no longer describes in detail.
