Abstract
Disclosed herein are several embodiments for shroud arrangements to be used in rotary engines using a plurality of rotors within the shroud arrangement. At least one of the rotors is not fixed to the shroud.
Claims29
A rotor assembly comprising:
- a. a shaft wherein a thrust load from a rear portion of a first rotor whose axis of rotation is not parallel to the axis of rotation of the shaft is transferred to the shaft through
- b. a first thrust bearing whose axis of rotation is concentric with that of the first rotor, and wherein the first thrust bearing then acts upon
- c. a wedge shaped plate with the angle of the wedge equal to the angle between the axis of rotation of the first rotor and the axis of rotation of the shaft and wherein the wedge shaped plate then acts against
- d. a second thrust bearing comprising and axis of rotation which is concentric with the axis of rotation of the shaft, and
- e. the thrust bearing then acts against a second thrust plate fixedly attached to the shaft.
2 more elements
A rotor assembly comprising:
- a. a plurality of rotors comprising at least a first and a second rotor having respective center axes that are offset from co-linear, and having lobes and valleys,
- b. the first and a second rotor each comprising an outer surface forming part of a spherical surface arranged in such a way that each outer partial spherical surface shares a common center;
- and
- c. a shroud body comprising an inner spherical surface operatively configured to surround the outer spherical surfaces of the rotors and the shroud body rotates at some angular velocity in the same direction as the rotors.
