給機。[Claim for Utility Model Registration] A male rotor and a female rotor that are arranged and supported in parallel within a casing are rotated by transmitting power from the engine to a speed increasing gear and a timing gear, and compressed by both rotors. In a mechanically driven supercharger that supercharges the engine with air, the gear force during rotation of the timing gear on the shaft of the male rotor is in the direction of the gas force acting on the male rotor. A helical gear is used in which the gear twist direction is such that the gas force acts in the opposite direction, and the timing gear on the shaft of the female rotor that meshes with the timing gear has gas force acting in the same direction as the direction of the gas force acting on the female rotor. Using a helical gear with a gear twist direction such that A mechanically driven supercharger characterized by using a helical gear with a gear twist direction.

Claims

[Scope of utility model registration request]

The male rotor and female rotor, which are arranged and supported in parallel inside the casing, are rotated by transmitting the power from the engine to the speed increasing gear and timing gear, and the air compressed by both rotors is supercharged to the engine. In a mechanically driven supercharger, the gear force during rotation of the timing gear acts on the timing gear on the shaft of the male rotor in a direction opposite to the direction of the gas force acting on the male rotor. A helical gear with a gear torsion direction is used, and the timing gear on the shaft of the female rotor that meshes with the timing gear has a gear torsion direction that acts in the same direction as the direction of the gas force acting on the female rotor. A helical gear is used, and the speed increasing gear on the shaft of any of the rotors is a helical gear whose gear twist direction is opposite to the gear twist direction of the timing gear on the same axis. Mechanically driven supercharger.
