Definitions

  • the invention relates to a transmission with a large reduction ratio in slow motion, in particular for roller shutters, awnings, curtains, closure elements and the like, with an input shaft and with an output shaft, with at least two intermediate gear stages and with a housing.
  • Such a gear unit is known from DE 195 38 866 AI and includes a first gear stage with gears and a second gear stage with an eccentric. All gear components are arranged in the gear housing, which is closed at the end by end shields.
  • the manufacturing outlay in particular the assembly outlay for introducing the individual transmission elements into the interior of the transmission housing, is in need of improvement.
  • the object of the present invention is therefore to provide a small-sized transmission, the transmission components of which can be arranged and mounted more easily than previously in the transmission housing.
  • the transmission 1 has an input shaft 2 with a high input speed with a low input torque and an output shaft 3 with a low output speed but a high output torque.
  • the first housing module 4 is assigned a first gear stage 6 with gear wheels 7, 8, which are mounted on a pin 9, 10
  • the second housing module 5 has the second gear stage 6 'with the planet gears 11, 12, which on the one hand with the intermediate shaft 13 and, on the other hand, mesh with an internal toothing of the housing module 5.
  • a pot wheel 14 is provided in a rotationally fixed manner with the intermediate shaft 13, which meshes with a toothing of the gear wheels 7, 8 and thus serves to drive the intermediate shaft 13.
  • the two housing modules 4, 5 are each provided with a bearing plate 17, 18 in the area of each end-side shaft passage 15, 16, which serves to mount the drive shaft 2 or the output shaft 3.
  • the figure shows that the bearing plate 17 is assigned a ball joint 19 which compensates for an angular offset of the drive shaft 2. Angular misalignment can occur because the drive shaft usually protrudes from the drive motor.
  • the end shield 17 can of course be a component of the drive motor, which is flanged directly to the housing module 4.
  • the end shields 17, 18 are arranged in a latching manner in the respective associated housing module 4, 5. The rotary / plug-in movement required for locking or releasing the connection in a bayonet fitting can be carried out much more simply and cost-effectively than a tubular screwing of the end shields 17, 18 to the housing module 4, 5.
  • the housing module 5 has an axially projecting collar 20 which has a diameter which is reduced compared to the outer diameter of the tubular housing module 5. This reduced diameter essentially corresponds to the inside diameter of the first housing module 4.
  • the collar 20 engages under a section 21 of the first housing module 4. This is preferably done with a press fit. This ensures that the two housing modules 4, 5 are arranged fixedly and centrally to one another.
  • the two housing modules 5, 6 are clipped together and it is either on the collar 20 or the cut 21 arranged in the radial direction resilient tab.
  • a radially oriented nose is provided on the tab, which engages in a recess on the associated component (collar 20, section 21).
  • gear modules to be preassembled and then assembled using the housing modules 4, 5.
  • housing modules 4 Of course, it is possible to set up a gearbox with any number of stages in the same way. So the invention is not limited to 2-stage gear.
  • an intermediate wall 22 is also provided in one piece on the housing module 5 in the region of the collar 20, which extends radially inwards to the intermediate shaft 13 and supports it in the radial direction.
  • the intermediate wall is solid and has a wall thickness in the axial direction which is several times greater than the wall thickness of the housing module 5 in the radial direction.
  • the wall thickness of the partition wall ensures a low surface pressure and a suitable choice of material, for example a self-lubricating plastic guarantees low friction values at the low speeds.
  • the housing module 5 forms with the gear stage 6 'a kind of independently manageable, versatile Reversible unit, which is built for example in large series and can be combined with different, variably designed gear stages 6 in the manner of a modular system.
  • the output shaft 3 is finally supported in the end shield 18.
  • the drive shaft 2 is set in motion by a drive device, so that the toothing 23 on the drive shaft 3 sets the two gear wheels 7, 8 in rotation.
  • These two toothed wheels 7, 8 are provided with a toothed projection 24, 25, which is directly in engagement with the internal toothing of the top wheel 14 and drives the planet gears 11, 12 and the planet carrier 29 provided with bearing needles 27, 28 via the toothing 26.
  • the planet carrier 29 is in turn non-rotatably connected to the output shaft 3 and serves in accordance with the rotational movement transmission.
  • each housing module should be designed to be as torsionally rigid as possible due to the high torques. That is why tubular shape is particularly advantageous.
  • the figure shows that the entire transmission 1 with the housing modules 4, 5 forms a slim unit, the housing of which is essentially tubular and the diameter of which is not larger than the diameter of conventional electric motors, so that the whole of the electric motor and transmission overall is slim and yet the individual gear stages can be preassembled separately from one another and assembled in a final assembly. It may be appropriate, even more as two gear stages using the modular design described.

Abstract

L'invention concerne une transmission à grand rapport de démultiplication lente. Cette transmission (1) comprend un arbre d'entraînement (3) et un arbre de sortie (3) ainsi qu'au moins deux étages de transmission intercalés (6, 6') qui assurent la démultiplication voulue. Chacun des étages de transmission (6, 6') est monté dans un module de carter séparé (4, 5), ces modules pouvant ensuite être fixés l'un sur l'autre de façon à être à fleur. L'invention permet une construction modulaire de la transmission, les modules individuels (4, 5) étant prémontés avec les étages de transmission individuels (6, 6') pour être réunis ensuite au cours d'un montage final. L'invention permet également de réduire considérablement la complexité de montage habituellement nécessaire pour installer les éléments de transmission appropriés dans les carters tubulaires. Enfin, l'invention permet de combiner différents étages de transmission (6, 6') avec différentes fonctions cinématiques ou différents rapports de démultiplication.
