  • a spur gear is known in which pre-assembled mounting units can be used from a mounting opening in an assembly step using a free mounting path.
  • the assembly opening lies in a dividing plane, which cuts through the entire housing and closes it via a cover to which a motor is flanged.
  • the mounting hole is significantly larger than the largest gear part which is introduced into the gear housing. The housing thus surrounds the gearbox on three sides.

  • the transmission unit comprises the gear parts required for the injection unit and / or the dosing unit, these being accommodated in a one-piece gear housing. Due to the one-piece or one-piece increased density is achieved by reducing the surfaces to be sealed. Since no different machined parts are to be put together, resulting in lower Sumollerolleranzen, so that a higher accuracy in the machining can be achieved. At the same time, the gear unit is characterized by its one-piece design. Stands that small wall thicknesses are sufficient for the gear housing, which contributes to a weight reduction. Assembly openings are provided for the assembly of the transmission parts located in the gearbox housing, which at the same time can serve for the connection of drive and driven areas.
  • All bearings and locating holes, such as fits, may be manufactured in one setting, i. be processed in one operation, so that the sum tolerances are significantly reduced as a result of two or more differently assembled and manufactured parts.

  • the gear housing 10 can ensure sufficient stability due to its one-piece construction, even with the lowest wall thickness, which is made even easier by the design as a cast housing. Since all bearings and mounting holes such as fits can be created in a Aufspannvorgang in the gear housing 10, a high precision is possible because no sum tolerances of two differently machined and assembled parts must be considered. This not only increases the life of the transmission but contributes to the overall precision of the injection molding machine, which in turn has a positive influence on the quality of the molded parts to be produced. When introducing the functional elements a backlash is guaranteed at the same time and that in the radial and axial direction with simultaneous sealing of the gear housing.
