Definitions

  • a geared motor is known from DE 10 2014 008 330 A1.
  • the invention is therefore based on the object of developing a geared motor, with a high gear ratio being able to be produced in a simple and cost-effective manner.
  • the geared motor has a housing part of the gearbox, a bearing flange, a stator housing of the electric motor, a rotor shaft and a bearing, the bearing being accommodated in the bearing flange, the inner ring of the bearing is plugged onto the rotor shaft, the bearing flange having a first cheek and a second cheek connected to the first cheek via a web, in particular wherein the second cheek is arranged on the side of the web facing away axially from the stator housing and the first cheek on the is arranged on the side facing away axially from the housing part of the transmission, the axial direction being aligned parallel to the axis of rotation of the rotor shaft, the first cheek being centered on the stator housing via a first centering collar, the first centering collar being formed on the first cheek or on the stator housing, wherein the second cheek is centered via a second centering collar to the housing part of the transmission, where
  • a circular ring is understood to mean an annular spatial area that resembles a flat, hollow cylinder.
  • the invention therefore makes it possible to achieve a smaller axial distance between the axis of rotation of the wheel and the axis of rotation of the pinion and thus also smaller gear ratios when replacing the bearing flange with another bearing flange in which the two drilling patterns are aligned coaxially to one another.
  • different variants of geared motors can be produced.
  • a high degree of variance can be achieved with just a few components, especially when producing geared motors in a series.
  • the axis of rotation of the rotor shaft is aligned coaxially with the discrete or integer axis of rotational symmetry of the drilling pattern on the motor side. The advantage is that the bearing flange can be easily aligned with the rotor shaft.
  • the axis of rotation of the rotor shaft is coaxial with the axis of rotation of the bearing.
  • a pinion is connected to the rotor shaft in a rotationally fixed manner, which is in engagement with a face-toothed wheel, in particular the axis of rotation of the wheel is aligned perpendicular to the axis of rotation of the rotor shaft, the pinion having a worm gear, in particular a ZA worm gear.
  • the housing part is manufactured as a cast part, with a channel passing through the wall of the housing part being manufactured by means of a slide, the pulling direction of which has a non-vanishing angle, in particular an angle between 10° and 40°, to the axis of rotation of the rotor shaft.
  • the advantage here is that the housing part has increased stability and rigidity on the input side.
  • the rotor shaft with the pinion protrudes through the channel into the interior of the transmission, so that the wheel, which is arranged in the interior area of the transmission, is in engagement with the pinion.
  • the rotor shaft with the pinion protrudes into the channel or through the channel.
  • the advantage here is that the pinion is predominantly arranged in the channel and the installation space is therefore used efficiently.
  • the axis of rotation of the wheel has a non-vanishing center distance from the axis of rotation of the rotor shaft.
  • the first centering collar is aligned parallel to the second centering collar, in particular wherein the axis of rotational symmetry of the first centering collar is aligned parallel to the axis of rotational symmetry of the second centering collar.

  • the first and second cheeks of the bearing flange are connected by means of ribs formed on the web of the bearing flange, in particular wherein the ribs, in particular with respect to the axis of rotation of the rotor shaft, are spaced apart from one another in the circumferential direction, in particular are spaced evenly, in particular wherein the, In particular, the outermost radial distance of the respective rib measured at a respective axial position, in particular related to the axis of rotation of the rotor shaft, decreases monotonically, in particular strictly monotonically, with increasing axial distance from the stator housing, in particular wherein at least two ribs have a different extent in the radial direction and / or wherein the extent of the ribs in the radial direction is a non-constant function of the circumferential angle, in particular wherein, at a respective circumferential angle, the radial distance area covered by the respective rib in the radial direction adjoins the radial distance area covered by the web.
  • the advantage here is that the bearing flange has increased rigidity and improved heat dissipation, in particular the heat loss from the bearing.
  • the different lengths also suppress resonance vibrations. This is because the ribs of different lengths are arranged distributed around the circumference and thus unevenly distributed ribs are formed around the circumference, so that corresponding natural vibrations or resonance vibrations are suppressed.

  • the advantage here is that a high degree of variation in the series can be achieved with a small number of parts.
  • the advantage here is that the second bearing flange can be used instead of the first bearing flange and a lower transmission ratio can therefore be achieved.
