Definitions

  • passages 7 and 8 being the means through which the liquid is supplied to and forced out of the engines chambers.
  • Both cams are provided with the equal number of teeth on cam lobes, whereby said number of teeth is preferably by. one to two teeth more than number of teeth of planet gears l.
  • the subject of the present invention is a gyrating-cam engine, designed particularly as a hydraulic engine of multiple power cycles per single revolution, said engine having radial cams and being intended as a power source for mechanisms requiring large torque, these mechanisms including particularly road wheels of vehi cles and hoisting drums.
  • theengine housing froms an outer cam in which an inner cam is installed this inner cam forming the engine rotor and having one lobe less than the outer cam.
  • This alternating supply of liquid controlled by means of a distributor, produces a gyrating-rotary motion.
  • the gyrating-rotary motion of the rotor is then resolved into the rotary motion by application of additional means, e.g., an articulated drive shaft.
  • the aim of the present invention is to eliminate the gyrating-rotary motion of theinner rotor-cam, the complex distributor, and a unilateral force causing distortion of cams and impairing the sealing between chambers formed by the cams.
  • the number of teeth on a single lobe is equal both for the inner and outer cam, and for a hydraulic engine it is advisable if this number is by one or ,two teeth more than the number of teeth of the jointly operating planet gear.
  • the planet gears running between the toothed cams allow that the concentricity of the cams can be obtained. thus eliminating the gyrating-rotary motion and gine cams can be greatly balanced and allows that high pressures can be applied even if the dimensions of engine elements aresmall.
  • the liquid pressure produced in the chambers betweenthe lobes of outer and inner cams presses the teeth of planet gears against the teeth of cams thus ensuring a good sealing of the chambers.
  • the teeth of planet gears adhere to the flanks of teeth of outer and inner cam irrespective of distortion of the cams.
  • FIG. 1 and FIG 2 are a schematic presentation of the engine operation principle
  • FIG. 3 illustrates the engine in a half-section in a plane perpendicular to the face of cams.
  • Planet gears 1 running between an inner cam 2 and an outer cam 3 are forming draw-forcing chambers 4, 5, and 6.
  • cam 3 causes that the volume of chambers 4 decreases and that the liquid becomes forced out of these chambers through a passage 8.
  • the planet gears l of the engine are rolling on and between the toothed inner cam 2 and the toothed outer cam 3, said cams being concentric.
  • the disks 11 and 12 are rotatably mounted on the axle of the inner cam 2 in bearing sleeves 13 and 14.
  • a collector pipe 18 screwed into the axle of the cam 2 exerts pressure on flange 17 thus fixing the said flange on the axis of the inner cam 2.
  • Drilled in collector pipe 18 are passages Sand 7 through which the liquid is supplied to and forced out of the working chambers formed between planet gears l.
  • the rotar'y part of the engine comprises the outer cam 3 with covering disks 11 and 13, and a coupling 19 being mounted on this part, said coupling serving as the engine power take off.
  • the flange 17 fixed on the axle of inner cam 2 serves as a fixing element for the stationary part of the engine.
  • a turn made by the outer cam of substantially 525 causes the planet gear to cover half of itsway and attain the half value of the lobe rise.
  • the planet gear was at a point as the outer cam turns by a further 52.5 the planet gear covers the way of another half rise of the lobe, and attains the crown or top of the lobe of the inner cam, while leaving entirely the lobe of the outer cam.
  • the profiles of the lobes are developed so that when the planet gear becomes engaged by the lobe of the inner cam, the lobe of the outer cam engages the planet gear. Obtaining such a profile is possible, if the number of teeth on the-perimeter of the planet gear, is smaller than the number of teeth on lobes of the inner and outer cams. The difference is preferably two teeth.
  • a gyrating-cam hydraulic engine comprising an outer cam, an inner cam mounted concentrically within said outer cam and forming a space therebetween and rotating toothed planet gears mounted between and in engagement with said cams and separating said space into working chambers, said inner and outer cams having toothed lobes, said inner cam having three lobes and said outer cam having a number of lobes exceeding the number of lobes of said inner cam by at least one, one of said cams being stationary and the other of said cams being rotatable.
