Abstract

The invention provides a shaft coupling of a mechanical supercharger, which is applied to the field of mechanical superchargers. The shaft coupling of the mechanical supercharger comprises a front wheel hub (1), a torque spring (2), a back wheel hub (3), a back notch (4), a back handle leg (9), a front handle leg (11) and a front notch (14), wherein the front wheel hub (1) is arranged into a cylindrical hollow cavity structure, the back wheel hub (3) is arranged into a cylindrical structure, the annular torque spring (2) is sleeved and installed outside the back wheel hub (3), the back wheel hub (3) is sleeved and installed in the front wheel hub (1), the front handle leg (11) of the torque spring (2) is clamped on the front notch (14) on the front wheel hub (1), and the back handle leg (9) of the torque spring (2) is clamped on the back notch (4) on the back wheel hub (3). By adopting the technical scheme, mechanical noise under a pulsating load can be effectively decreased, and the abrasion of the inner surface of the torque spring and the corresponding positions of the wheel hubs can be effectively decreased.

Description

technical field [0001] The present invention relates to the field of mechanical superchargers, and more specifically, the present invention relates to a coupling of a mechanical supercharger. Background technique [0002] In the field of engines, superchargers are generally used to improve the power of the engine and reduce the emission of harmful substances. In the existing supercharger, there are a pair of intermeshing vane rotors, and the non-meshing vanes of the two rotors respectively form a control volume with the casing, and the purpose of transmitting air is achieved by the continuous replacement of the control volume. As long as the amount of air delivered to the intake manifold is greater than the instantaneous engine displacement, the intake pressure can be increased, ultimately increasing the power density of the engine. [0003] figure 2 It is a schematic diagram of the power transmission and air transmission between the existing supercharger and the engine (s...
