Definitions

  • the invention relates to a toothed rotor set for a pump, in particular for a lubricating oil pump for internal combustion engines.
  • the toothed rotor is similar to a toothed ring pump with a toothed design, wherein the function and operation of a toothed rotor set, which corresponds to a gerotor pump.
  • the pressure chamber is not separated from the suction chamber by a crescent-shaped filler, but a special design of the teeth - based on the trochoid toothing - ensures the seal between the toothed ring and externally toothed pinion.
  • the internally toothed ring has one more tooth than the pinion, so that with appropriate design of the teeth, the tooth heads touch exactly opposite the tooth engagement point.
  • the disadvantage of gerotor pumps is that internal leakage and thus poor volumetric efficiency occurs through this head clearance in the gerotor pumps. As a result, high pressures can not be built up at low speeds.
  • the pump forms a generic Zahnahnungsrotorsatz consisting of an outer ring with an internal toothing and a gear externally recorded therein with external teeth, wherein the internal toothing is formed by rollers rotatably mounted in the outer ring and a tooth more than the outer toothing, wherein the outer toothing of the gear fine teeth superimposed with a much smaller module and each roller on its perimeter with a fine toothing has the same module, in which engage the teeth of the gear.
  • the function of the toothed rotor set results from the fact that a drive torque acts on the inner rotor via a drive shaft and rotates the latter. From the toothed inner rotor, a force is transmitted to the planetary gear, on the one hand results in an impact force through the center of the planetary gear and a circumferential force, which causes a torque of the planetary gear. The impact force acting on the bearing ring causes it to rotate.
  • a hydraulic machine which is formed of a rotatable bearing ring with bearing pockets, wherein in the bearing pockets rotatably mounted rollers are arranged with recesses on the peripheral surface, with an eccentrically mounted to the bearing ring inner rotor with approximately star-shaped outer contour, wherein the teeth of the star in the Recesses of the rollers engage.
  • the rollers and the inner rotor do not have the fine toothing according to the invention, as a result of which engagement errors occur, in particular in gear tooth sets with a higher number of teeth, for example 11/12.
  • the design can only be run with very small tolerances.
  • a Veriereungsrotorsatz consisting of a rotatable bearing ring with bearing pockets in which rotatably mounted planetary rotors are arranged, which form an internal toothing, with an eccentrically mounted to the bearing ring inner rotor with approximately star-shaped outer contour, which is provided with an outer toothing the external toothing has one tooth less than the internal toothing and the toothing of at least one of the two rotor systems has an arcuate component at least in partial regions of the tooth form of the toothing.
  • the advantage of such a designed Zahnahnungsrotorsatzes is that due to the arcuate portion of the tooth shape substantially rolling friction and no sliding friction occurs, so that the wear on the teeth is minimized.
  • the tooth shape in the region of the tooth tip and / or the tooth root, is arcuate.
  • Such a design of the tooth shape in the region of the tooth head and / or the tooth root makes it possible for very large impact forces (radial forces) to be transmitted, it being possible for the proportion of peripheral force to be transmitted to be small.
  • the tooth head and the tooth root in contrast to the involute toothings known in the case of toothed rotors, are introduced into the rolling process, i. the rolling of the toothed planetary rotors on the toothed inner rotor curve, with included.
  • the convexly curved tooth flank of the planetary rotor and the concavely curved tooth flank of the inner rotor form a relatively large sealing surface during tooth engagement, which seals the displacement chamber from the suction region into the pressure region when the displacement chamber passes. Even deviations of the squareness of the rotor do not lead to leakage of the displacement chamber.
  • the region of the tooth tip and / or the tooth root has the tooth shape a flattening.
  • the torque acts through the toothed inner rotor via the toothed planetary rotor on the bearing ring it comes, geometrically caused, almost to a stop of the planetary gear.
  • the planetary rotor tooth heads were flattened. The size of the flattening depends on the field of application of the toothed rotor. At low speeds and high pressures, a strong flattening is necessary.
  • the region of the tooth tip and / or the tooth root has the tooth shape a large radius of curvature.
  • the flattening of the planetary rotor tooth heads also causes an improvement in the transmission of power (Hertzian pressure) from the planetary rotor to the bearing ring.
  • the arcuate portion is at least partially formed as a cycloid.
  • the cycloid has proven to be particularly advantageous in terms of roll-off and transfer of impact forces. This cycloid toothing ensures perfect sliding low rolling, even with considerable changes in curvature and small radii of curvature, which in turn reduces wear.
  • the tooth form is formed as involute.
  • the tooth flanks of the toothed inner rotor and the toothed planetary rotor are formed by an involute, but in this embodiment, engagement errors may occur more easily than in an embodiment whose tooth flanks are formed as cycloids.
  • the toothing has a low-wear surface.
  • the low-wear surface can be replaced by a chemical, in particular thermochemical and / or physical surface treatment can be achieved.
  • the surface can also be galvanized. Further advantageous surface treatment methods are caburation and nitration and / or nitrocarburizing, boriding and / or chromating.
  • At least one fluid channel is arranged in the region of the bearing pockets.
  • the fluid channel may be connected to the pressure side of the pump so that lubricating oil is continuously supplied between the planetary rotor and the bearing pocket in order to ensure an improved lubricating film structure.
  • all movable parts of the toothed rotor set in particular the bearing ring and / or the planetary rotors and / or the inner rotor on at least one end face on a circumferential ridge.
  • This circumferential ridge serves as a seal within the housing in which the toothed rotor set is received.
  • movable parts have a sealing surface on their end faces, which extends over the entire surface, with the exception of the teeth.
  • the seal according to the invention by means of the circumferential ridge has the advantage that the high friction forces occurring in the known seals are greatly reduced and thus the toothed rotor set works lighter and thus more efficient.
  • the circumferential ridge has a width which represents the optimum between sealing effect and frictional force.
  • the invention relates to a method for producing a Verzahungsrotorsatzes, wherein this is in a molding process, preferably by means of powder metallurgy process, plastic injection molding, extrusion, die casting, especially aluminum die casting, and stamping process is prepared.
  • a complex toothing as having the toothed rotor set according to the invention, is simple and inexpensive to produce by means of these methods.
  • a filing and sawing which is known in the usual gears Can be used, can find no application in the invention, since the toothing is too complicated for this purpose.
  • the toothed rotor set in a pump in particular a lubricating oil pump for internal combustion engines, is used.
  • Veriereungsrotorsatz is used as a motor.
  • Fig. 1 shows a Vernierungsrotorsatz 1 invention, consisting of a rotatable bearing ring 2 with bearing pockets 3, in which rotatably mounted planetary rotors 4 are arranged, which form an internal toothing, with an eccentrically mounted to the bearing ring 2 inner rotor 5 with approximately star-shaped outer contour, which is provided with an external toothing 6 is, wherein the external toothing 6 has a tooth less than the internal toothing.
  • the toothed rotor set 1 has a suction region 7, a pressure region 8 and a displacement chamber 9.
  • a drive torque M1 acts on the toothed inner rotor 5 via a drive shaft 10.
  • a circumferential force F2 acts on the toothed planetary rotor 4, which is mounted in a bearing ring 2 (housing), from the toothed inner rotor 5.
  • the circumferential force F2 is divided into two components, the impact force (radial force) F3 and the torque M4, both acting on the toothed planetary rotor.
  • the impact force F3 acts through the center of the toothed planetary rotor 4, which is mounted in a bearing ring 2, and sets the bearing ring 2 in rotation.
  • the toothed rotor set 1 according to the invention can be used as a pump for generating pressure by the inner rotor 5 is driven via a drive shaft 10.
  • the toothed rotor set 1 according to the invention can also be used as a motor by the pressure area is pressurized, so that the inner rotor 5 is set in rotation and the drive shaft 10 drives.
  • Fig. 1a shows the Veriereungsrotorsatz 1 in a second working position. In this a maximum pressure is generated because the inner rotor 5 operates at most on the planetary rotors 4.
  • Fig. 1b shows a plan view of the Veriereungsrotorsatz 1, wherein both a suction side 21 and a pressure side 23 are shown.
  • the suction side 21 opens an inlet opening 22, which may be formed, for example, laterally as a bore in the toothed rotor set receiving housing.
  • an outlet opening 24 opens into the pressure side 23.
  • the diameter of the Auslrawöffung 24 is less than that of the inlet opening 22, since in the latter a higher flow rate is given.

  • the arcuate portion 14 of the toothing thus consists of the tooth base 12 and tooth tip 11, which transmit the impact force F3 between the toothed inner rotor 5 and the toothed planetary rotor 4.
  • Only a small proportion of the toothed surfaces consists of sliding surfaces in the region of the tooth flanks 15, which convert the circumferential force F4 into a rotational movement of the toothed planetary rotor 4.
  • the tooth head 11.1 of the toothed inner rotor 5 is calculated so that it applies exactly in the tooth root 12.2 of the toothed planetary rotor 4, and ensures trouble-free rolling.
