Abstract
The utility model relates to the technical field of mechanical transmission supercharger, in particular to a planetary gear transmission supercharger which comprises a shell, a belt pulley, a shell cover and a pressure impeller, wherein the belt pulley is connected with the left side of the shell; the shell cover is connected with the right side of the shell; the pressure impeller is mounted in a cavity of the shell cover; a planetary gear, a sun gear, an inner gear and a support shaft are disposed in the shell; and the inner gear is connected with the periphery of the inner wall of the shell via a shell inner ring. With a traditional turbocharger replaced with a planetary gear transmission speed-up mechanism, the planetary gear transmission supercharge is advantaged by dominant speed, and simultaneously sluggish phenomena brought by the turbocharger are eliminated. When an engine starts or runs at low speed, the supercharger can be driven to provide a large supercharge ratio and a large gas supply quantity so as to meet the requirement that large torsion is generated when the engine runs at low speed, and performance of the engine can be greatly improved.

Background technique
The pressurized machine product mostly is a turbosupercharger at present, and the high-temp waste gas of promptly discharging with motor drives turbine, thereby drives coaxial pressurized machine.Its advantage is the original just part exhaust energy of discharging of motor capable of using, so the thermal efficiency is higher.Basically adopt this series products in the market.Shortcoming is that the exhaust energy of discharge is little, not enough pressurized machine air feed demand when motor starting and low speed.This will cause the low engine speed moment of torsion to reduce, and starting and accelerating ability weaken.
The model utility content
Not enough in order to overcome existing turbosupercharger at starting air feed when the low speed, the deficiency a little less than the supercharging power, the utility model provides a kind of planetary pinion transmission pressurized machine.
The utility model solves the technological scheme that its technical problem adopted: a kind of planetary pinion transmission pressurized machine, comprise housing, belt pulley, clamshell and pressure impeller, and belt pulley is connected the housing left side; Clamshell is connected the housing right side, presses impeller to be installed in the clamshell cavity, is provided with planet wheel, sun gear, internal gear and support shaft in the housing; Internal gear is connected on the inner walls circumference through the housing inner ring, and planet wheel is installed on the support shaft through connecting rod, is connected with a joggle with sun gear and internal gear respectively; The housing front end is provided with the fuel inlet fitting post; The rear end is provided with oil drainage hole, and the bottom is provided with spill port, and the support shaft axle center is provided with lubricating oil path.
According to another embodiment of the utility model, comprise that further planet wheel has three, is evenly distributed on the support shaft.
According to another embodiment of the utility model, comprise that further sun gear is positioned at the central authorities of three planet wheels.
According to another embodiment of the utility model, comprise that further belt pulley is connected the outer end of support shaft.
According to another embodiment of the utility model, further comprise and press impeller to be connected with sun gear through rotating shaft.
According to another embodiment of the utility model, comprise that further an end of lubricating oil path is communicated with the fuel inlet fitting post, the other end is communicated with the center and the oil drainage hole of planet wheel, sun gear.
The beneficial effect of the utility model is; Substitute traditional turbosupercharger with the mechanism of planetary pinion transmission speedup, on speed, account for very big advantage, also got rid of the sluggishness that turbosupercharger brings simultaneously and looked like at present; When motor in starting with during low speed; Can impel pressurized machine to supply with bigger pressure ratio and air demand, produce the requirement of high pulling torque when satisfying low engine speed, thereby improve engine performance greatly.
