Definitions

  • the present invention relates to a method for producing a planet carrier for a planetary gear, which has a sun gear, one or two ring gears, at least one planet gear and a drive shaft.
  • Planetary gears are particularly well suited to combine high gear ratios with a compact design.
  • An example of this is the so-called Wolfrom coupling gear, which still has high efficiency with a high gear ratio.
  • a particularly simple coupling gear is called a Wolfrom gear.
  • the drive shaft is connected to a sun gear that works with a planetary gear block.
  • the planet gear is supported on an internally toothed ring gear which is fixedly connected to the housing, the web running empty as a planet carrier. The movement is transmitted via the planet carrier and the planet gear, which is designed, for example, as a stepped planet.
  • the planet gear in turn meshes with a second internal gear that forms the output.
  • a planetary gear of this type is suitable for a compact construction which enables high transmission densities in a small space.
  • gears are required for the transmission of power from high-speed drive motors. These gears are said to have a small backlash when changing the load direction. Furthermore, they are characterized by a rigid, light and compact design.
  • a planetary gear with a driven sun gear, a first and a second internal gear, each of which is fixed and the second is rotatably driven and forms the output and with planet gears inclined extending axes are mounted in a planet carrier in such a way that they are in constant tooth mesh with the sun gear and the ring gear.
  • the planet gears are designed as step planets with small and large step gears, the teeth of the step gears having different modules.
  • Another planetary gear with a driven sun gear and two internally toothed ring gears is known from DE A 43 25 295 by the applicant.
  • the planetary mounted on planetary axes in the planet carrier planet axes are at an acute angle to a central axis of the planetary gear is inclined relative angeord ⁇ net.
  • the planet carrier, which runs idle here, is mounted on a bushing with low friction via a ball bearing, the bushing for adjusting the axial position of the planet carrier rests on one end on a shoulder on a ball bearing and can be fixed on a spacer by means of a locking ring.
  • An essential component of such a planetary gear is the planet carrier, which generally consists of a forged component and a punched or cut guide disk, which are welded together. A variety of processing steps are required for this manufacturing process, including an additional welding process.
  • Cast planet carriers have also been used, but they require an equally high level of machining effort in their manufacture.
  • the expensive molds required for the production of the cast planetary carriers have a shorter service life than the forming tools required for the fine cutting of the guide disks.
  • the planet carrier produced according to the invention can be made lighter than the conventional planet carrier, thereby making it possible to save weight.
  • the invention will be explained in more detail with the aid of the drawing, which shows an advantageous embodiment. Show it:
  • the conventional carrier shaft is shown schematically, and 2 and 3 are two guide disks, which are produced as spacer parts and are arranged at a distance from one another and parallel to one another on the carrier shaft, with a number of riveting tools 4, the number of which is equal to the number of planets to be recorded, m are connected according to the invention with one.
