Definitions

  • a pump or a motor with the toothed rotor set according to the invention has a higher efficiency than the pump with a toothed rotor set known from the prior art, since a lower torque has to be used in order to overcome the friction in the system. Due to the design, the gear rotor set according to the invention also enables a larger delivery volume in comparison to the gear rotor set known from the prior art.
  • the gear rotor set according to the invention has a higher degree of efficiency, since when the inner rotor rotates clockwise, the planet gears undergo a counter-clockwise rotation and thus additional lubricating oil in the tooth gaps of the planet gears is conveyed from the suction side to the pressure side.
  • a disadvantage of the generic toothed rotor is that it is not possible to ensure clean rolling without interference under all operating conditions.
  • the movement of the planet gears relative to the bearing ring comes to a standstill in one position.
  • the gear rotor set is used in a pump, in particular a lubricating oil pump for internal combustion engines, gearboxes, hydraulic units and high-pressure cleaning systems.
  • Fig. 1 shows a gear rotor set 0.1 according to the prior art, consisting of a rotatable outer rotor 0.2 with bearing pockets 0.3, in which rotatably mounted planet gears 0.4 are arranged, which form an internal toothing, with an inner rotor 0.5 eccentrically mounted to the outer rotor 0.2 with an approximately star-shaped outer contour , which is provided with an external fine toothing 0.6, the star-shaped outer toothing having one tooth less than the inner toothing.
  • the toothed rotor set 0.1 has seven planet gears 0.4.
  • the largest portion, the arcuate portion 23, of the toothing thus exists on the tooth base 19 and tooth tip 18, which transmit the impact force F3 between the toothed planet gear 7 and the toothed 2 outer rotor. Only a small proportion of the toothing surfaces consists of sliding surfaces in the region of the tooth flanks, which convert the frictional torque MR into a rotary movement of the toothed planet gear 7.

Abstract

Ensemble rotor à denture pour une pompe ou un moteur, qui comporte un rotor externe rotatif pourvu d'un trou interne pratiquement en forme d'étoile présentant une denture interne fine, et un rotor interne monté de manière excentrique dans le trou. Ledit rotor interne est pourvu de poches paliers pour des roues planétaires qui possèdent une denture fine à l'aide de laquelle lesdites roues s'engrènent dans la denture fine du rotor externe. Les roues planétaires possèdent une denture constituant une denture externe, ladite denture externe possédant une dent de moins que la denture interne du rotor externe.
