Definitions

  • the present invention relates to a bevel gear transmission having an input drive element which interacts with a core bevel gear transmission by means of which an output drive element can be driven.
  • Bevel gear transmissions also referred to as angular gearings, are known and available on the market in a wide variety of forms and designs. They serve essentially to redirect torque.
  • Bevel gear transmissions There are therefore different basic types of bevel gear transmissions, designed for example with (hypoid transmission) or without (bevel gear transmissions) an axial offset. Said transmissions differ substantially in terms of their input drive subassemblies and are therefore designed differently.
  • a disadvantage of the previous bevel gear transmissions is that separate housings, separate units and separate production lines are generally necessary to produce a bevel gear transmission with different input drives.
  • EP 0 517 387 A2 discloses a tool adapter which redirects an input drive torque through an angle to provide an output drive torque.
  • a conventional angular gearing is used here.
  • EP 1 326 032 A1 discloses a type series of differently-dimensioned electric motors, each of which has a transmission flange-mounted onto the output drive side.
  • the transmission is embodied as a separate component.
  • U.S. Pat. No. 6,234,037 B1 describes a modular transmission system in which different electric motors can be connected to or flange-mounted onto the transmission.
  • DE 102 34 749 A1 discloses a bevel gear transmission in which an input drive bevel gear 8 engages in and interacts with an input drive shaft mounted on a housing.
  • FR-2 547 007 A presents a conventional common differential transmission as is also used in the field of vehicle technology.
  • the present invention is therefore based on the object of producing a universal bevel gear transmission which can be easily produced in a modular manner for different output drive variants and input drive variants. This is intended in particular to make it possible for customer-specific requests to be realized and implemented very quickly, so that a customer-specific transmission can be delivered very quickly. It is also intended to provide a bevel gear transmission which is cost-effective to produce. It is also intended to make it possible to produce a plurality of different angular gearings with one and the same core bevel gear transmission, with regard to input drive variants, with regard to output drive variants and different installation sizes, with substantially the same components.
  • a bevel gear transmission having an input drive element which interacts with a core bevel gear transmission by means of which an output drive element can be driven, characterized in that a plurality of different output drive elements or variably selectable output drive variants can be connected to the core bevel gear transmission.
  • the bevel gear transmission it has proven to be particularly advantageous for the bevel gear transmission to be formed substantially from one common, universal core bevel gear transmission in which one bevel gear is inserted and which, opposite the bevel gear, forms a universal interface I.
  • An input drive element can be plugged in perpendicularly with respect to the bevel gear or the universal interface I, which input drive element likewise forms a universal interface II for flange-mounting different selectable input drives.
  • any desired different bevel gear transmissions with different input drive and output drive variants can be produced for all bevel gear transmissions with variably selectable input drive elements and variably selectable output drive elements.
  • different output drive variants can be used for different kinematic properties, different output drives, for example with regard to an output drive shaft or output drive flanges.
  • further output drive stages designed as single-stage or multi-stage drive output stages with different kinematic properties can be attached by means of corresponding universal interfaces and suitable interfaces.
  • Said drive output stages can be embodied as step-down or step-up transmissions with different output drives, formed by output drive shafts or output drive flanges.
  • FIG. 1 is a schematically illustrated partially cross-sectional illustration of a bevel gear transmission, in particular angular gearing, according to the invention in modular form;
  • FIG. 2 is a longitudinal cross-sectional illustration through a region of the input drive element with two different attachable input drives
  • FIG. 3 a is a schematically illustrated longitudinal cross-sectional illustration through the bevel gear transmission, in particular in the region of a universal interface I with different output drive elements which can be attached thereto;
  • FIG. 3 b is a schematically illustrated partially longitudinally cross-sectional illustration with further output drive variants, with it being possible for different output drive stages to be selectively connected by means of an interface.
  • a bevel gear transmission embodied as an angular gearing, has a core bevel gear transmission 1 which has a housing 2 .
  • a bevel gear 4 if appropriate embodied as an internal bevel gear, is inserted in an opening 5 by means of a bearing 3 .
  • a universal interface I is formed in the housing 2 opposite the opening 5 , which universal interface I serves to hold and center arbitrarily selectable output drive elements 6 , as indicated merely schematically in FIG. 1 . It is also possible if appropriate for an interface 7 to be connected instead of an output drive element 6 to the universal interface I of the core bevel gear transmission 1 , to which interface 7 any desired number of different output drive stages 8 can be attached.
  • the output drive stages 8 can be embodied as step-down transmissions or step-up transmissions. It is also possible within the scope of the present invention for the different output drive stages to be connected to an output drive shaft by means of an output drive flange 25 (see FIG. 3 b ). Here, it is possible by forming a universal interface III, see FIG. 3 b , for different drive output stages to be connected to the interface 7 and therefore to the core bevel gear transmission 1 .
  • Different covering elements 9 can be universally connected to the housing 2 in the region of the opening 5 , in particular in the region of the bevel gear 4 , so that the opening 5 is completely closed off if the closed embodiment of the covering element 9 is used, or if appropriate, a plug-in opening is formed in the region of the bevel gear 4 if a covering element provided with an opening 10 is used.
  • a receiving opening 11 is provided approximately perpendicular to the opening 5 or to the universal interface I, into which receiving opening 11 an input drive element 12 can be plugged.
  • the input drive element 12 has a housing 14 which forms a flange 13 which can be connected to the housing 2 of the core bevel gear transmission 1 , in particular to the receiving opening 11 .
  • the input drive element 12 is then precisely centered with the receiving opening 11 by means of the flange 13 . If appropriate, the core bevel gear transmission 1 and the input drive element 12 are fixedly welded to one another.
  • a bevel gear shaft 15 of at least partially hollow design is mounted in bearings (not illustrated in any more detail or numbered here) within the housing 14 of the input drive element 12 .
  • the bevel gear shaft 15 is formed by a bevel pinion and a bevel pinion shaft.
  • a universal interface II is formed opposite the bevel gear 4 . It is possible, as merely indicated in FIG. 1 , for different input drives 16 to be selectively plugged into the universal interface II as desired.
  • the input drives 16 as illustrated in the exemplary embodiment in FIG. 2 , can be embodied as a motor add-on subassembly 17 or a planetary pre-stage 18 .

  • the planetary pre-stage 18 can be embodied as a single-stage or multi-stage planetary pre-stage 18 , with the latter likewise having a shaft flange 20 for holding an electric motor or the like.
  • the bevel gear transmission R is shown in modular form, with it being possible for any desired different output drive elements 6 to be connected to the universal interface II.
  • the first two output drive elements 6 are if appropriate also dimensioned differently with different flanges or shafts for different output drive variants. Corresponding hollow shafts can also form the output drive element 6 .
