A wedge placed between adjacent coils in a generator comprises a wedge body having a generally triangular portion to be positioned at a radially inner location, and a radially outer portion. The radially outer portion includes ends that will be spaced at axial ends of the wedge when the wedge is positioned within a generator. The ends have a first surface spaced a first distance from an apex of the triangle. The end walls extend above the first surface at each of two spaced positions axially inwardly of the ends of the wedge. The end walls are connected to side walls that extend near circumferential edges of the wedge. An open pocket is formed within the wedge body at locations between the side walls and axially between the end walls.

A shaft for a clutch member comprises an engagement portion having a plurality of teeth spaced about a shaft centerline. The teeth have a tooth profile with a negative rake angle. The negative rake angle is between 1° and 2°. The teeth have a chamfer angle between the face of the negative rake and the face of the clutch end surface. The chamfer angle is between 65° and 75°. A rotor assembly for a generator, a generator and a method are also disclosed and claimed.

A gearbox has a first rotative component and a second rotative component, the gearbox having a rotary input and a rotary output, a first brake for braking the first rotative component of the gearbox against rotation thereof, and a second brake for braking the second rotative component of the gearbox against rotation thereof. The rotary input drives the rotary output if the first brake brakes the first rotative component of the gearbox and the rotary output drives the first rotative component of the gearbox if the second brake brakes the second rotative component of the gearbox.

A generator coupling assembly includes an output housing, an output member rotationally supported by the output housing, a generator powered by the output member, and a clutch adapter. The generator includes a generator stator, a generator rotor rotatably supported within the generator stator, a shaft coupled to the generator rotor, and a clutch member arranged on the shaft. The clutch adapter is coupled to and radially retained by the output member, and includes a clutching structure configured for selective engagement with the clutch member to engage the clutch member and the clutch adapter for co-rotation.

A generator rotor shaft includes a shaft body extending through a first axial distance, and being hollow. Spline teeth are formed in an inner bore of the hollow shaft body. The ratio of a distance from one end of the hollow body to a remote axial end of the spline teeth and compared to the overall length of the shaft body is between 0.3 and 0.6. A rotor balance assembly, a generator, and a method of forming a generator rotor shaft are also disclosed and claimed.

A rectifier assembly includes first and second housings surrounding a pair of electrical rings. Each of the electrical rings communicates with a pin. Bolts secure a spring to hold diodes against an inner wall of the electrical rings. The first housing includes openings opposed to the bolts to allow access to the bolts for tightening the bolts to hold the spring, and bias the diodes against the inner periphery of the electrical rings. A rotor balance assembly, a generator, and a method of assembling a rectifier assembly are also disclosed and claimed.

A disclosed terminal block assembly for a generator includes a terminal block with a base with first and second transverse terminal surfaces adjoining one another. One of the terminal surfaces includes an increased width greater than a length of a cable terminal lug for providing a lightning strike and creepage barrier. The terminal surfaces include spaced apart protrusions extending from the first and second surfaces to provide spaced apart terminal areas overlapping the first and second surfaces. First and second terminal studs are disposed within each corresponding first and second terminal areas and are electrically connected by a bus bar.

A bypass valve assembly for a generator includes a spring cover with a flange which extends in a radial direction from a spring cover body. The spring cover body defines an overall length dimension, the overall length dimension to an end of the spring cover body to the flange dimension defines a ratio between 1.6:1-1.2:1. The bypass valve assembly also includes a valve sleeve with a multiple of windows. Each of the multiple of windows includes a longitudinal edge which defines a longitudinal edge radius and corner radius.
摘要:
A generator has its length shortened by placing springs in a space in a casing that includes an output shaft, which is driven by an input shaft, and a yoke for separating the two shafts. The generator is assembled by placing a spring in a space in a casing having a first part. The space also has a yoke in it. A rotor bearing is placed in the space adjacent to and impinging upon the spring. A second part of the casing is attached to the first part of the casing so that the spring is pre-loaded therein. The generator also utilizes a guide for holding a spring. The generator also has a thrust plate for applying a force of the springs upon the rotor bearing.
