Definitions

  • the present invention concerns a wind power engine in which the rotor runs on bearings at a stationary hollow shaft, and in which the output shaft driven by the rotor via a gear transmission extends through a stationary hollow shaft which serves as bearing housing for the output shaft.
  • Wind power engines nowadays are all provided with a speed increasing wheel gearing in the transmission between the rotor and a generator or similar energy con ⁇ verter for the utilization of the wind energy.
  • the transmission is built up over used parts from lorries so that the hub of the engine wings is bolted to the brake drum of the rear axle-assembly in such a way that a first stage in the transmission will be the crown wheel and the bevel pinion in the locked differential gear of- * the rear axle-assembly.
  • the second stage in the transmission normally consists of v-belts or roller chains to the generator.
  • Wind power engines built up from new parts only have most often industrial gears in different types as speed increasing member.
  • Wind power engines the transmission system of which is built up by automobile parts, normally are charac ⁇ terized by a comparatively more noiseless operation than is the case of wind power engines where common industrial gears are used. This is caused by the curved tooth gearing of the crown wheel and the bevel pinion.
  • the use of automobile parts loaded completely, different from their original purpose is not satisfactory, and V-belts or rol ⁇ ler chains are rather unsuitable for use in wind power engines which must be able to run without service for long periods and often exposed to shock exitating loads.
  • a wind power engine which is characterized in that the gear transmission comprises a gear rim of a crown wheel which is secured to the rotor and which is mounted to transmit the drive power of the rotor to a be ⁇ vel pinion at the output shaft via at least one with crown heel and a bevel pinion provided intermediate shaft which runs on bearings at the hollow stationary shaft and where ⁇ in the rotor itself is also running on bearings at the hollow stationary shaft.
  • the purpose of the invention is obtained because of the intermediate shaft which extends in a direction crosswise to the rotor axis, and because of the conical gears.
  • the short length of construction is obtained because the free space in the center of the gear rim of the crown wheel is utilized for a part of the crown wheel at the intermediate shaft and the engagement of this with the bevel pinion of the output shaft.
  • the length of construction may be further mini ⁇ mized and the stiffness of the construction further in ⁇ creased when the stationary hollow shaft is secured to a radially outwardly extending supporting flange and the ro ⁇ tor is running on bearings on this supporting flange con- centrical with the gear rim of the crown wheel secured to the rotor.
  • conical gears at the intermediate shaft have their tooth planes turned to each other.
  • a single intermedi ⁇ ate shaft is used and where the bearing load of the inter- mediate shaft in axial direction of the intermediate shaft becomes low because the axial forces from the two gear en ⁇ gagements are oppositely directed.
  • a single momentum transmitting bearing having horizontal axis such as a cross roller bea ⁇ ring is defined a hitherto unknown mounting of a rotor for a wind power engine and whereby is obtained an increase of structural stiffness and strength besides a further de ⁇ crease of structural length or building-in length of the wind power engine.
  • the axis of the intermediate shaft intersect the plane of the crown wheel gear rim of the rotor in a point positioned within the circumference of said gear rim.
  • the wing bracket or wing flange of the wind power engine is mounted concentrically to the crown wheel rim of the rotor at an arbitrary position from the front side of the rotatable housing of the rotor to the rear flange of the rotor or possibly to the tubular hub of the rotor.
  • the axis of the rotor and the axis of the output shaft extends in a mutual distance.
  • At least one of the gears of the transmission is a crown wheel or a bevel pinion for an automobile, preferably the crown wheel gear rim of the rotor.
  • At least the crown wheel gear rim of the rotor and the gear engaged with this gear rim have hypoid tooth gearing.
  • this bar can be a complete regular rectilinear regulation bar.
  • there are two intermediate shafts in the rotor casing each having a bevel pinion in engagement with the crown wheel gear rim of the rotor and each having a crown wheel in engagement with the bevel gear of the output shaft.

  • the applied crown wheels and bevel pinions may e.g. be a matching set of crown wheel and bevel pinion from a lorry and a matching set of crown wheel and bevel pinion from a passenger car.
  • a typipal lorry motor produces approximately 200 KW and its maximum torque is of the magnitude 100 daNm. With a gear transmission ratio in the low gear the torque at the bevel pinion shaft exceeds 500 daNm.
