Alternators and improvements to rotary internal combustion engines

The present invention provides improved alternators for use alone or in combination with, for example, rotary internal combustion engines wherein the alternators are characterised by absence of moveable bearings or mountability to existing driving shafts by use of an aligning plate and through passage through the rotor of the alternator to mount to the driving shaft. The alternators may be further characterised by plural rotors on the rotor driving shaft. The rotary internal combustion engines of the present invention are characterised by fixed size combustion chambers formed of radial recesses around a rotor amongst other features. |

DETAILED DESCRIPTION (A) Alternators According to a first aspect of the present invention there is provided an alternator comprising a housing accommodating, a rotor and a stator, and, in use, a drive shaft for the rotor, which alternator has no moveable bearings within the housing supporting the drive shaft for the rotor.
Preferably the alternator has no bearings at all within the housing for supporting the drive shaft.
This is most especially appropriate where the alternator is to be mounted to an existing drive shaft of, for example, an internal combustion engine.
Particularly suitably, the alternator has a rigid aligning plate arranged to centre the housing and stator rigidly over the drive shaft.
A plurality of long bolts is suitably further provided to rigidly bolt the housing and stator to the rigid aligning plate.
Preferably, the rigid aligning plate has a convex profile, suitably arching toward the front of the alternator, to enhance its strength and the rigidity, which it imparts to the alternator assembly.
The alternator housing suitably comprises a casing comprising a front casing part and a rear casing part and the stator is sandwiched between the front casing part and the rear casing part forming a substantially rigid box structure around the drive shaft.
Preferably the rigid aligning plate is secured to the rear external face of the rear casing part.
Preferably, the alternator is without an integral drive shaft for the rotor, the alternator having a passageway therethrough, including through the rotor, to mount onto an existing drive shaft.
Such existing drive shaft is suitably integral with or coupled to a motor such as, for example, the internal combustion engine of a car or other vehicle and the alternator housing is suitably adapted to be bolted to a rigid structure or housing from which the existing drive shaft protrudes and by means of which the alternator is centered over the drive shaft.
In principle, the motor may be any supplier of motive force and could, for example, be a wind-driven propeller or water-driven impeller or the engine of a large or small powered appliance of any type
