Abstract: A supercharger constructed in accordance to one example of the present disclosure includes a housing, a first rotor, a second rotor, a first timing gear, a second timing gear, a first rotor shaft, a second rotor shaft and a coupling. The first and second rotors are received in cylindrical overlapping chambers of the housing. The first timing gear has a gear body that includes first helical teeth. The gear body further defines a central bore and a series of openings. The second timing gear has second helical teeth and is arranged in meshed engagement with the first timing gear. The first rotor shaft supports the first rotor and the first timing gear. The second rotor shaft supports the second rotor and the second timing gear. The coupling has a coupling body and includes a series of protrusions configured to be inserted into the series of openings of the gear body.

Abstract: A supercharger constructed in accordance to one example of the present disclosure includes a housing, first and second rotors, a bearing plate and a pair of sleeves. The first and second rotors are received in cylindrical overlapping chambers of the housing, the first rotor supported by a first rotor shaft, the second rotor supported by a second rotor shaft. The bearing plate is coupled to the housing and has an oil cavity side and an air cavity side. The bearing plate is formed of aluminum. The pair of sleeves can be received by the bearing plate and support respective bearings rotatably supporting respective first and second axle shafts. The pair of sleeves are formed of steel.
