Abstract

The invention provides a mechanical supercharger structure applied to the technical field of automobile engine parts. One side of an addendum circle (7) of each rotor blade (6) of a screw rotor (4) ofthe mechanical supercharger structure is in smooth transition connection with a left involute (8); the other side of the addendum circle (7) is in smooth transition connection with a right involute (9); the left involute (8) is in smooth transition connection with a left envelope line (10); the right involute (9) is in smooth transition connection with a right envelope line (11); the left envelope line (10) is in smooth transition connection with a left dedendum line (12); and the right envelope line (11) is in smooth transition connection with one side of an indent right dedendum line (13).The mechanical supercharger structure provided by the invention is simple in structure, enables the screw rotor to have the characteristics of high area utilization coefficient and constant meshing clearance, and has the characteristics of delaying a reflow process, reducing discharge pulse and improving heat insulating efficiency, the working noise generated during the working of a supercharger is reduced, and an NVH (Noise Vibration and Harshness) characteristic of the supercharger is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile engine components, and more specifically relates to a supercharger structure. Background technique [0002] Engine supercharging technology can greatly increase the power and torque of the engine without increasing the cylinder volume, so it has been paid more and more attention. Compared with other supercharging methods, mechanical supercharging has been widely used in automobiles due to its low speed, sharp transient response and easy matching with engines. The supercharger is a gear-driven dual-rotor compression machine that successively completes the three working cycles of intake, compression and exhaust by means of the rotors meshing with each other. In the traditional form, the backflow of gas is realized by the high-pressure gas flowing back to the base circle volume to equalize the pressure at the moment when the base volume is connected to the exhaust port. When the supercharger is ...
