A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a first side coupling assembly, a second side coupling assembly, a central hub and a plurality of coupler pins. The first hub is mounted for concurrent rotation with the input shaft. The second hub is mounted for concurrent rotation with the rotor shaft. The first side coupling assembly has a first side coupling body and a first side elastomeric insert. The first side coupling body includes an inboard body portion having a first series of pockets and an outboard body portion having a second series of pockets. The first side elastomeric insert has a first and second plurality of lobes. The pockets of the first and second series of pockets are tangentially offset relative to each other and each receive respective first and second plurality of lobes therein.

Elastomer series coupling damper for supercharger

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a central hub, and a plurality of coupler pins. The first hub can be mounted with the input shaft. The second hub can be mounted with the rotor shaft. The central hub can be disposed in between the first and second hubs. The central hub can have an elastomeric body that defines a series of passages therein. The passages can taper inwardly throughout and provide incremental dampening against the first and second plurality of pins. The plurality of coupler pins can be received in the central hub bores. The first and second plurality of pins can be received by the passages in the elastomeric body.

Differential case

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a first side coupling assembly, a second side coupling assembly, a central hub and a plurality of coupler pins. The first hub can be mounted with the input shaft. The second hub can be mounted with the rotor shaft. The first side coupling assembly can have a first side coupling body and a first side elastomeric insert. The second side coupling assembly can have a second side coupling body and a second side elastomeric insert. The central hub can define central hub bores therein. The plurality of coupler pins can be received in the central hub bores. The first and second side elastomeric inserts provide dampening between (i) the first side coupling body and the central hub and (ii) the second side coupling body and the central hub.

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger can include a first hub, a second hub and an elastomeric coupling. The first hub can be coupled to the input shaft and include a first plurality of coupling pins extending therefrom. The second hub can be coupled to the input shaft and include a second plurality of coupling pins extending therefrom. The elastomeric coupling can include a coupling body having a series of openings. The first and second coupling pins can be alternately received by the respective openings. The elastomeric coupling can be configured to absorb torsional variations from the input shaft.

Elastomeric coupling for supercharger

A torsion damping mechanism for a rotary blower is provided that includes an input hub adapted to engage a first end of a torsion spring and an output hub adapted to engage a second end of the torsion spring. An intermediate hub is fixed for rotation with a first drive member. A bearing member includes an inner portion connected for rotation with the intermediate hub and an outer portion connected for rotation with the output hub. The bearing member may be a one-way bearing that permits torque to flow from the output hub into the intermediate hub and the first drive member when the output hub is driven in a first rotational direction, and permits the output hub to rotate relative to the intermediate hub with no substantial torque transfer therebetween when the output hub is driven in a second rotational direction.

Torsion damping mechanism for a supercharger

A torsion damping mechanism for a rotary blower is provided that has improved durability and ease of installation into the rotary blower. A rotary blower including a torsion damping mechanism according to an embodiment of the present invention is also provided.

A rotary blower () includes a torsion damping mechanism for transmitting torque from an input drive () to a first timing gear (), the mechanism including an input hub (), an output hub (), and a torsion spring () having an input end () and an output end (). The housing () defines a chamber () containing fluid rotation of the timing gears resulting in an air-oil mist. The input hub and output hub define an axial gap () intermediate the input and output ends of the torsion spring. The output hub () defines an angled passage () having a radially outer end () in communication with the axial gap (), and a radially inner end, whereby rotation generates a flow of the air-oil mist through the angled passage () and between the outer cylindrical surface of the hubs and the inside surface () of the torsion spring ().
